Software Engineering Why is it necessary?

To understand the need of software development, we need to stop briefly to look back to the recent past of computing. This history helps to understand the problems that began to become apparent in the late sixties and early seventies, and the solutions that have been active in the field of software for creating. They mentioned some of the problems, such as "The software Crisis," so named for the symptoms of the problem. The situation might have called "The Complexity Barrier," so named for the primary cause of the problems. Some refer to the software crisis in the past tense. The crisis is not yet over, but thanks to the development of many new techniques that are now included under the heading of software development, we have made and will continue to have progress.

In the early days of computing was the primary concern in the building or acquiring the hardware. Software almost expected to take care of yourself. The consensus held that "hardware" is "hard" to change, and the "software" of "soft" and easy to change. According to most people in the industry carefully planned hardware development but gave considerably less forethought to the software. If the software is not working, it was believed that it would be easy enough to change until it works. In that case, why bother to plan?

The cost of software has attained such a small fraction of the cost of the hardware that no one considered very important to manage its development. Everyone, however, saw the importance of producing programs were effective, and ran quickly because of the time saved on expensive hardware. People time was assumed to save machine time. This is how people process efficient received little priority.

This approach was deemed appropriate in the early days of computing, when the software was simple. However, the computing matured, programs and projects become increasingly complex growing, and programs regularly since then defined, written, operation and maintenance of all the same person, the program began to develop teams of programmers to meet someone & # 39; expectations.

than the individual effort through the work of the group. Communication and coordination which once went to a man's head had to happen between leaders of many individuals, so the whole process is more complicated. As a result, communication, management, planning and documentation became critical.

Consider this analogy: carpentry work to build a simple house for himself without more than a general concept of the plan. He was able to work things out and change the work progresses. It & # 39; and that the early programs were written. But if the home is more complicated, or if it is built for someone else, the carpenter has to plan more carefully, that the house was to be built. Plans need to consider the future owner before construction begins reviewed. And if the house is built by many carpenters, the whole project will certainly have to be planned prior to the start of work to build a single table of the house, the other did not build another house on the other side. Scheduling becomes a key element to the cement contractors pour the basement walls before the carpenters start the framing. As housing becomes more complex, and more people & # 39; s work should be coordinated, blueprints and management plans required.

The programs become more complex, the early methods used to make blueprints (flowcharts) were no longer satisfactory to represent this greater complexity. And it's so hard to become a person who needs a program written to convey to another person, the programmer just what he wanted, or for programmers to convey to each other what they are doing. In fact, no better visualization methods become even more difficult with a programmer to keep track of what he was doing.

The time needed to write programs, costs began to exceed all estimates. It was not unusual for systems cost more than twice as many had predicted and the weeks, months or years longer than expected. The system is turned over to the client often does not work properly because of money or time ran out before the programs could be developed as originally planned. Or the program is so complex that any attempt to fix a problem produced more problems than it fixed. As a client, finally he saw what he starts, often changed their minds about what they want. At least one very large military software systems project costing several hundred million dollars was abandoned because it could never be made to work properly.

The quality of the programs has become a big concern. As computers and programs used in more basic tasks, such as monitoring of life-saving equipment, program quality took on new meaning. Because of increased dependency on computers and in many cases no longer do without them, we discovered how important it is to operate.

Making a change within a complex program turned out to be very expensive. Often that the program was not a little bit different so heavy that it was easier to throw out the old program and start again. This was, of course, expensive. The evolution of software development approach to learning systems develop that are built well enough the first time that simple changes can be easily solved.

However, the hardware was growing less and less expensive. Tubes were replaced by transistors and transistors were replaced by integrated circuits until micro computers costing less than three thousand dollars has become a multi-million dollars. As to how quickly change is made, the cost of a given amount of calculation is reduced by half every two years. Since this adjustment, the time and cost to develop the software is not as small as the hardware that may be disregarded.

As the cost of hardware plummeted, software is still written by people whose wages are rising. The savings systems improve the productivity of software development from the use of compilers, assemblers, and database management is not acting as fast as the hardware cost savings. Indeed, today software costs not only can no longer be ignored, become greater than the hardware cost. Some current developments such as nonprocedural (fourth generation) languages ​​and artificial intelligence (fifth generation), show promise in increasing the productivity of software development, but are just now beginning to see that it is possible.

The other problem was that the previous programs was often not fully understood what the program needed to do. After the program has been completed, the client began to express dissatisfaction. And if the customer is dissatisfied, ultimately the producer also unhappy. As time went by software developers learned to lay out paper and pencil exactly what you intend to do before starting. Then it would review the plans for the client, if the client is satisfied & # 39; s expectations. It is simpler and less expensive to carry out these changes in the paper and pencil version than to the system after they are built. Using good planning makes it less likely that the changes to be made when the program ends.

Unfortunately, until a few years ago no good method of representation existed to describe satisfactorily systems as complex as those that are being developed today. The only good representation of what the product will look like it was the finished product. The developers were able to demonstrate to customers what they planned. And customers could not see whether what the software was what they wanted until it was built. Then it was too expensive to change.

Again, consider the analogy of building construction. An architect draw a floor plan. The client usually refers markets, as the designer intended and does not give feedback that is appropriate. Floorplans reasonably easy for the layman to understand, because most people are aware of the drawings representing geometrical objects. The architect and the client share common concepts of space and geometry. But the software engineer must represent the client system that includes logic and information processing. Since they have no common concepts of the language, the software engineer must teach a new language that can communicate with the customer before.

Furthermore, it is important that this language should be simple, so you can learn.

Types of data cables

needed a transmission medium to transmit information from the source to the destination. The information is usually a sign that you have to travel a long distance. To do so, the transmission medium can be wired or wireless. Wired transmission signal passes the cable from one device to another. But the wireless transmission are transmitted without a physical conductor of electromagnetic waves. Three types of cables, for example.

twisted-pair cable 1-
2 coaxial cable
3 fiber optic cable

Twisted

The two twisted-pair cable copper conductors, each with its own plastic insulation and twisted together. A wireless signal and the other is used to ground reference. The advantage of twisting is that both wires also touched against external influences. So the unwanted signals are canceled out as the receiver calculates the difference between the two signal wires.

This two types of cables, for example.
1- UTP (unshielded twisted pair)
2- STP (shielded twisted pair)

STP cable plus a metal shield, which is insulated twisted pairs. But it lacks UTP cable. The most common UTP RJ45 connector.

The unshielded twisted pair cable is classified into seven categories based on quality. Category 1 cables used in telephone lines, the data transfer rate of about 0.1 Mbps. As used in Category 5 LAN with a 100 Mbps data transfer rate.

Performance of twisted-pair cable is measured by comparing attenuation is a function of frequency. Damping increases frequencies above 100 kHz.

These cables are used for phone lines to voice and data channels. DSL lines and Local Area Networks twisted pair cables.

coaxial cable

coaxial cable (coax) carries high frequency signals than twisted-pair cables. Coax central core conductor solid wire enclosed insulation which an outer conductor of aluminum foil. This outer conductor completes the circuit. External driver closed an insulator, and the whole cable is protected by a plastic cover.

These cables are categorized based RG (radio government). RG-59 used for Cable TV, RG-58 Ethernet thin and thick RG-11 Ethernet. The connector used in these cables is called BNC connector; It is used to connect the end of the cable to a device.

Although the coaxial cable greater bandwidth, but the attenuation is much higher compared to twisted-pair cables. It is widely used in digital telephone networks where a single cable can carry data at speeds up to 600 Mbps. Cable TV networks use RG-59 coaxial cable. Traditional Ethernet LANs also use this cable.

fiber-optic cable

The fiber optic cable transmits signals in the form of light. Using optical fibers to guide the reflection of light over a single channel. It consists of two main parts: core and cladding. Core is denser compare and cover made of plastic or glass. Housing Works guard core. The difference between the density of the core and cladding so that a light beam passing through the core is reflected from the casing, rather than being broken into.

There are two possible modes of propagation of light optical fiber, such as: multi and single mode. Multimode fiber allows multiple beams from a light source to move through the core. Multimode step-index fibers, the core density remains constant from the center to the edge. But in multimode graded-index fiber core density gradually decreases from the center, the core, to the edge. Graded index fiber creates less distortion in the signal compare the step-index.

Two types of connectors for fiber optic cables. The SC connectors used for cable TV, and ST connector used for connecting cable to networking devices. Attenuation of fiber optic cable is very low compare to other two. It provides high bandwidth and immunity to electromagnetic interference. Light weight and greater immunity to tapping makes it advantageous cable.

fiber optic backbone networks are often used for high-bandwidth and cost efficiency. Local networks such as 100Base-FX network and 100Base-X use this cable. It is also used in cable television companies.

How to Start Your Own Online Gaming website and stupid money

When I said I wanted to start an online game site my friend asked me if I wanted to sell Xbox games and Nintendo games. I laughed and told him not to. I asked, uncomprehending face will be a game site with little cost to play games of skill that he be remembered in the early 90 & # 39; s. I told him not to. I told him that I wanted to start an online gaming website where people can play against each other, and play new 3D graphics games. He also asked if I wanted to get paid for it. So here is the story of how I did it.

start online gambling site is not difficult. There are plenty of software that is already made for you ……. Prices vary. You should do your research to see if you want different functions. Also you can get a customized website, which I advise you to always, if you want to stand out among competitors. You can get done customizing Google.com, Elance.com, Readycoder.com and others. Now, if you want to make it a business to manage the game site, like a real business. You can get someone to install it, or pay $ 20 extra and get the company that bought it to install it. I can show you plenty of ways to do a lot of things are very cheap and free. But I say to the entrepreneur who wants to really, really well and get started fast. It will not take much to get started, but be prepared to spend some money to make some profit.

Now I know you guys are thinking, well how do you get money. There are ways to get paid game site. There are advertisements. The best known is the Google AdSense. You can sign up for free, and Google is not to get technical, you can send the robot spiders is to look at the website and determines what types of ads should be placed. There are also independent advertising companies, where they can make pop-up ads or tracks on the site to make money. Also, if you use Mochi Ads, you can make money from advertising networks. The fact that a work Mochi Ads that when loading a game on the website of the trade will play automatically. You can also sell your links to your website. If you start getting a lot of traffic, people will want to link to you. You can sell links if you also want to make some revenue. And of course you can sell your own ad space by submitting to places like Craigslist, toy libraries and so on. You may also be advertising partners, where to get money if you buy the product of your website. With these sources of income coming in every month consistently while you are sleeping, you & # 39; ll only be a fool not to try to start their own gaming business. Yes there is a lot of competition, but there is more money than the competition. So why not get the cake?

The key to getting all this traffic. You can get traffic banner ads, Google AdWords, social media and more. I & # 39; ve looked into advertising to MySpace and Facebook, which is very well, because nobody thought of advertising. So the so-called competition does not exist.

I hope this information will help you with some inspiration and ideas on how to make money online doing something you love and play what you want. Good luck and never stop!

Google – the best social environment for Equal Opportunities

over the Internet attack by the Obama administration's executive power. This does not bode well for Internet entrepreneurs and political speech. The following is an analysis of how the Internet and especially Google has created a free world-wide social environment. The governments of the world should examine the Internet Society. You might learn something.

known as the Google search relevant information on the Internet. There are other browsers or search engines such as Yahoo, Explorer, MSN, Bing, etc. However, Google is more than just a browser.

Google has managed to create a solid foundation in the natural and social environment in a virtual free society, geographical or language barriers.

on fairness, I strongly biased towards individual freedom. I grew up under communism, but more importantly, to witness the transition from communism to a free society and loss of freedom. The communist movement is expected to power all international masses and become a major world communist system. Will Google and the Internet around these days, have embraced communism, and he might have learned something useful: Freedom of the masses is very constructive. I would like the current politicians a look and learn something about the environment created by Google and still cherish.

Larry Page and Sergey Brin started Google in January 1996 as a research, when they were both PhD students at Stanford University in California. Originally, Google ran under the Stanford University website, a domain google.stanford.edu.

The domain google.com was registered on September 15, 1997. The company on September 4, 1998, a friend & # 39; s garage in Menlo Park, California.

Google's name comes from "Googol". Googol refers to the number 1, followed by 100 zeros. It's such a big number, it can not be achieved, if you count the grains of sand in the whole universe. I thought that means an infinite number of people and the interaction does not seem to end. Google has more than one million data centers around the world and processes over one billion search requests and twenty petabytes (1000000000000000) of user-generated data every day, which is an incredible achievement. Google just launched a $ 100,000 private investors.

Larry Page and Sergey Brin had an idea, a dream and a goal: Match other peoples & # 39; dreams and desires with each other, so that all may benefit. If the seller had a good product or service, Google has made it easy for the search party to find. The author of the book is also published in a book and sell it without adding a space to rent. Google made it easier to promote the book. Talented people can start a home business shoe string through the night. There are billions of sites on the Internet for all sorts of information or products for sale. All that information is not sent to individuals or companies waiting to be found and / or shared with interested parties and prospects. Google does not create the information; Individuals and institutions did.

Google & # 39; s mission has been to develop the best possible presentation of any investigation. This is not an easy task, certainly not on the Internet. Complex algorithms, as well as on-site assessment is used to request connection to the delivery points. Before Google was created in the early browsers such as Netscape, MS Explorer, Yahoo, and dozens of cataloging techniques used straight-forward words or phrases and associate them to the affected areas. However, when dealing with billions of pages and posts every day, it is very difficult to determine which site offers the best and most relevant information for a query. Google & # 39; s browser, satisfactory results usually come out on top of the first page, and similar information with millions of posts. People rarely look beyond the first three pages.

Larry Page had an idea to evaluate the order and importance of pages, you can count back links on a given page. The total amount of links is important and where they are from.

For example, if I were a small business designing home theaters and had no money on advertising my business, I design a web page all kinds of instructions and a diagram of the portfolio is to help prospects understand how to deploy the project. The site as a tutorial. The next step would be to contact a few large distributors home theater furniture, electronics, cables, etc. and ask them to link educational site that belongs to them and offered to customers as an educational tool for do-it- yourself project. beneficial for all parties. The same concept works when a person skilled in the public useful information on a variety of electronic publications. The author & # 39; s connection will point to his site and the Google index, and is entitled to it.

Google this new technology PageRank, where a website & # 39; s relevance was determined by the number of pages, and the importance of those pages linked back to the original site.

Google received the patent describes that PageRank mechanism. The patent was officially assigned to Stanford University and lists Lawrence Page as the inventor. By 2006, the name "Google" is somehow part of everyday language, which is the word "Google" should be added to the Merriam Webster Collegiate Dictionary and the Oxford Angol Dictionary, refers to "using the Google search engine to obtain information on the Internet."

This feature is very important to be equal social opportunities because it has allowed creativity to be distributed on the Internet almost no cost to the author. Before this technology is applied, web competitor had to spend a lot of advertising dollars to promote the site. Otherwise, no one has found it. The search engines do not index. Since 2006,

Google has added a wide range of services and capabilities either through acquisitions or internal development. It is not my intention to do a thorough analysis of all its properties. I will outline the key features and free tools that Google provides to its subscribers.

Google and its function

Google has been criticized often too big and too dominant in the Internet field. Critics generally not to mention the valuable services Google offers to both large and small businesses and individual entrepreneurs. Most importantly, the real value to the end user, the potential consumer products and services advertised or promoted via the internet.

Google makes money by providing a sound foundation for advertisers and many useful free advertising tools. Google does not advertise. Advertisers do. It's a mutually beneficial relationship.

Google's advertising tools

Google Analytics allows website owners to track where and how people use in-depth research on the web more users can go wherever he wants to go. This is a very powerful tool that helps web designers to correct and optimize the organization of information and perspectives presented by monitoring their behavior while visiting the site.

Google AdSense allows website owners to display these advertisements on their websites and earn money every time you click ads. Google automatically puts only those ads that are relevant to the content on the site. If you are visiting any of these ads you will find interesting, you can click and the website owner collects a small fee. I want you to remark that these ads are pennies for advertisers.

Google AdWords allows advertisers to display ads Google content network through either a cost-per-click or cost-per-view system. This daily monitoring and financial control facilities is a real advertising services. Advertisers have a set of related keywords and ads specific performance testing day. Interestingly, Google has a price bidding system. If you offer a senior position in the upper side and if the ad attracts more visitors than the competition, in addition, Google will gradually decrease the cost of advertising. It is possible to have a very top position on the site and pay less per click than the other below. It encourages creativity and unique content, which in turn will make the campaign more successful.

Keywords Services, all the above services may not be very useful if you have something that means selecting the right keywords and phrases that fit your potential prospectors looking for. Do not forget to answer requests in writing. Google's extensive support services that will help in the selection of appropriate keywords and monitor the number of links associated with competition. These powerful tools allow you to determine the demand and competition, solely on the basis of keywords.

There were other services, such as Gmail, Google News, Orkut, and more being added all the time. There are no limits to the creativity of a free social environment, such as by Google.

I'm not trying to minimize the contributions of other browsers such as Yahoo and Explorer. This article is not really Google as a Web browser. This international society free Google helped create access to knowledge and economic development.

Economic impact

The cost of running websites can be as low as $ 5.00 per month. Blogs free and can be used. The cost of entering the international business is very low. There are thousands of people who live by selling books, which are often not even their own. Rock bands can record and publish music for free. I could go on and on. All this is made possible by that to a certain extent, Google affordable promotional skills.

The most important thing is that Google managed to create this social environment, because there was no government oversight or regulation. The only self-policing policy dealing with abuse services like spam. When the Chinese government tried to interfere with the operation, Google decided to get out of China.

Conclusion

Imagine a world governance, where all freedoms are guaranteed: freedom of expression, freedom of association, freedom of trade and free exchange of ideas and opinions, (it is including political). Internet only to Google, the Conciliation and governance.

Do not allow the government to do this in some form of regulation in the name of "public good".

English as a foreign language, diving instructor, freelance travel writer and promotion activities, and IT are some ways in which, for those who prefer an extended visit to the land of smiles is basic adventures.

Job in Thailand and tourists

While there is a certain degree and TEFL (English as a Foreign Language) certificate English in Thailand job search is the easiest path to becoming independent in Thailand. Depending on education and experience in teaching in Thailand is a relatively simple task to accomplish, and one of the most stable and lucrative career in the & # 39; Farang & # 39; exploration of old Siam.

5 Fail-Safe & # 39; cash-generating strategies & # 39; To Make Tons of Money Online The Comfort of Your Home

One of the most positive thing that can happen to a person than to begin working from home online business and make it successful. Several reasons come to mind quickly as to why people are attracted to the high earning an income through affiliate programs; especially the need to direct the public has been discontinued, do not arise in the management responsibilities and the need to stock an inventory is missing.

How an Internet genius is not necessary when operating a home business online and are just as important as the income can be done in the comfort of the home environment and during the hours you select.

Just like every business situation is beneficial to understand the ins and outs of the methods of creating an online income using an affiliate program. Understand the basics and to learn some strategies and approaches some of the items that need to be understood before it to see the cash flow on the Internet. The level of success and income rests entirely in your hands and yours alone.

One strong recommendation is to avoid the many scams scattered all over the Internet. These include: internet pyramids, CPA offers suggestions to read various documents, such as e-mails and questionnaires to fill in, but a few that fall into this category. Programs such as these are only the money the owner & # 39; s pocket.

If you really care about successfully create an online income affiliate program that is already in the five online income generating methods that are guaranteed success:

5. E-Book Creation: This method is a very profitable and aggressive approach to earning an income. But, it does not require a high level of effort and experience to substantial income writing e-books. This method is not recommended for novice internet entrepreneurs.

4. E-commerce: Online marketers very well with this approach and believe that grandpa Internet businesses. This approach involves selling a specific product and does not require an extensive business background, the loyalty of suppliers and customers and may be very time consuming, depending on the level of experience. This approach would not be my recommendation is not until there was no chance to get your feet wet.

3. CPA Network: This method is simple, and promotes the creation of online earnings. You receive payment for each referral sent to various organizations and owners. On the flip side, CPA programs often pay pennies for each referral and it may be some time before you start seeing any significant income. This would require a huge amount of traffic to create a significant and continuous income.

2. Google AdSense: similar to the CPA network program run, you can send a payment for each referral and the completion of certain forms of individual leading the search. The primary difference lies in the fact that all transactions in Google.

1. Affiliate Marketing: This approach would be the first choice to create a significant and continuous income. It does not need to sell, maintain inventory of the products in question or receive a relatively small amount to obtain referrals to direct heavy traffic.

Each product supports, via the Internet, I receive a commission, quick and easy. Typically, the amount of commission to move the 60 percent bracket, and is based on the price; is not that shocking?

Website or blog is often the method of choice for most affiliate marketers when supporting products. But it really is not necessary and we can start up without an income, either.

Without a doubt, the fastest and easiest way to create an online income through affiliate marketing. I usually take about an hour for the web site and confirm some products, lean back in a few hours, and then watch the cash flow begins.

What is the difference between Web 1.0 and Web 2.0?

Web 2.0 is a buzzword commonly used to encompass a variety of new procedures and the World Wide Web. Despite the fact that most of the economic cycle, some of the key attributes colligated Web 2.0 includes the emergence of social networks, two-way communication, different & # 39; Adhesive & # 39; multifariousness techniques and major content types. Although most Web 2.0 is running on the same platform as 1.0, there are some important differences. Our goal is to lead out the key features of the elementary characterized by differences in interest 2.0.

enamours combination of Web 2.0 concepts on the Web in recent years. The exact definition delicate and difficult to categorize the binary label "Web 1.0" and "Web 2.0". But there is a crowded separation of a series of extremely popular Web 2.0 sites such as Facebook and YouTube, and the old Web. These separation seeable when fabricated onto the various axes, such as the technological and structural sociological.

One key difference between Web 1.0 and Web 2.0 that the creators are very few Web 1.0 most of mere users will only benefit consumers, content, and any user can content generator Web 2.0 and the various technological segélyökkel expanded potential increase content generation.

Another difference between Web 2.0 and Web 1.0 can be based on time. The term "Web 2.0," coined around 2004, and many of the first true Web 2.0 began moving in late 2003 and early 2004, the websites that have been modified a bit structures since the early 2000 & # 39; Before you can be counted on Web 1.0 (for example, IMDB).

The most important feature of Web 2.0 is that these sites increase the users to expend as much as possible on their site. They offer strong incentives increasing stickiness on the site. The majority of the Web 1.0 site links to external sites, users can easily follow those links to other sites. The primary reason is that most Web 1.0 sites tends to cover a topic and do not require users to log in to access them. On the other hand, Web 2.0 sites encourage intra-site activities, usually requiring users to log in and build links with the rest of the site.

Web 1.0 sites were one-way communication while Web 2.0 to build two-way communication medium. Web 1.0 was autocratic and top-down. On the other hand, Web 2.0 and democracy from the bottom up. Instead of the New York Times website about 1.0, what is important stories of the day was Digg.com, Buzz and Yahoo.com depicts the story of the users voted the most important.

Web 1.0 sites must be read passively openly. Web 2.0 tempt to participate, to vote content up or down grading it, noting it and submit new posts.
