Improving Network Performance
Nowadays, it seems that everyone has a computer and is discovering that communication technologies are necessary. E-mail, Internet, and file transferring has become a part of the modern world. Networks allow people to connect their computers together and to share resources. They allow people to communicate and interact with each other. The days of the lone PC are diminishing.
At the same time, computers are getting faster than ever. The most powerful PC five years ago couldn’t be sold for half of its original price today. This poses some problems to the consumer. New technologies can’t be driven by older technology. As innovations continue to be invented, the computer of yesterday is fast outpaced by the technology of today.
While processor and memory speed have been increasing astronomically, the speed of common networks have not. Networks tend to progress more slowly because of the large capital investment needed to implement one. Tearing out the old network to install a new one is just not feasible in many cases. Because upgrading the hardware on the network is so difficult and uneconomical, many ways have been invented to increase the perceived speed of the network.
Computer games have traditionally driven the market in regard to processor power and speed. Running a spread-sheet or a word processor on a 386 is not unthinkable, as these "business" applications have little real-time processing requirements. In contrast, the goal of a computer game is to immerse the player in an environment that is suitably realistic, so that it is intuitive and fun. The term "suitably realistic" is pushing technology to its limits. With a fast enough computer, modeling every aspect of our physical world is conceivably possible.
Combining the two ideas of interactive computer games and interactive communications seems only natural. A multiple player simulation extends interaction beyond the single player simulation, but introduces increased programming complexity. Multiple programs on different machines have to be managed, and the participants must coordinate communication among themselves (Gossweiler 1). This paper will cover these aspects of network performance, specifically in regard to a computer game that is the accompanying senior project.
The speed of the underlying communications hardware accounts for much of t...

...e screen at ten updates per second, and an object is moving at five centimeters per frame, then the 80386 would move the object 5*10 = 50 centimeters every second. On the Pentium computer though, the program quite possibly could be running at sixty frames per second. On this computer, the object would move 5*60 = 300 centimeters, or three meters. The solution to this problem is to base the movement on time instead of frames. Instead of moving five centimeters in a frame, the object would be specified to move at 50 centimeters per second (Gossweiler 6). That way, on a fast computer, the animation will be smoother, but the object will end up in the same place.
Through all of this, the most important thing to remember is that optimization depends on the application. Increasing speed requires creative solutions to simple problems, and not all solutions work well. Optimizing performance requires a little trial and error, a little creative thinking, some common sense, and a lot of effort. When creating a program, the critical point is to make the program work and exceed the expectations of the users. The speed of a simulation is not worth much if it is not easy to use and fun to play.
Video games use several complex parallel processing machines to render gaming action in real time.

Amongst the shelves that are packed with the latest computer software, sits a genre of games, that does not get the recognition that it deserves. Simulation games. These games do not give the player level after level of mind-boggling graphics, blood and gore, or even the feeling of accomplishment. Their one purpose is to give the control to the player, that they would normally not get in their everyday lives. By definition a simulation game is a game where the player must take on a role that is different than his or her everyday life.
Soon, the Internet underwent a transition from a single network to a linked one, becoming a network of networks, making it the largest information source in the history of the world. Through the 1980's, the "Net", itself, sparked a massive demand...
In the early years of computer and network research and development many systems were designed by a number of companies. Although each system had its rights and were sold across the world, it became apparent as network usage grew, that it was difficult, to enable all of these systems to communicate with each other.

Networking is a technological instrument which has important utilization in communication, it can be voice communication or video communication, but it has some limitations that most of the time we can not keep them as evidence in our communication cycle, because of that it is better to use written form communication such as emails, text messages, and fax.
Figure 2.11 above shows the network topology in a single lab. In the lab, a star topology is used to connect a printer, a wireless access point and 50 personal computers with a single special device known as switch. Instead of using hub, a switch is used to identify which computer system is connecting to which port. Switch knows exactly where a frame is received from and which port it wants to send to, without increasing the network response time. Unlike a hub which divides the bandwidth among the systems when multiple PCs are broadcasting, switch enables system users to access the maximum amount of bandwidth regardless the number of PCs transmitting. Thus, a switch is considered as a better choice than a hub because it maintains the performance instead of degrading.
Instead of only focusing on the faster processor they also make the processor better such as Intel release the first desktop with dual core processor in 2005. The computer also developed from desktop to laptop then now to tablet PC. Microsoft was the first to introduce this tablet PC. Computer industry also keeps developing the graphic system for user to experience the picture almost similar to the reality. They make it keep it transform from 2-dimension (2D) to 3D and up until now it has increasing to 6D. User can buy the computer which is user friendly, come in many size and with better function. The community can buy the computer since nowadays it’s affordable to buy. Nowadays, education system also has been using the technology in the teaching as teaching aids.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
The invention of computers has made a huge change in human civilization and society, by changing the way people think. Computers replaced jobs and tedious repetitive thoughts that were done by human originally. People became more and more reliant on computers, and thus, computers became essential to our lives. Computers can manufacture products quickly, and eliminate possible human errors. As technology progresses, new ideas have been brought into computer to make them perform more efficiently. Also, scientists and engineers tend to make things “smaller”, so we can enjoy the benefits from electronic devices anywhere and anytime. Therefore, size and efficiency are two main points for consumers. Desktop computer and laptop computer are representatives for each of these concepts. Although desktops and laptops come from the same origin, they are different in many ways.
In the computer world, networks are the primary means of inter-computer communications. The building and maintenance of a network is the responsibility of the network manager. The network manager must have the expertise to design and implement an appropriate network for his client. The proper design of a network is based on more than a few principles. However, the job of the network manager encompasses more than simply building a useable network, although that is the end result.
Computers in technological development demand more efficient networking. In a very short period it has changed the way we have looked at things since centuries. It is one industry that is going to shape our future for centuries to come Coming from a background of Electronics and Communication Engineering, I have developed an interest to probe into the area of Networking and Computer Networks. Hence I wish to do Masters in Computer Science (CS) as my major.
The computer has progressed in many ways, but the most important improvement is the speed and operating capabilities. It was only around 6 years ago when a 386 DX2 processor was the fastest and most powerful CPU in the market. This processor could do a plethora of small tasks and still not be working to hard. Around 2-3 years ago, the Pentium came out, paving the way for new and faster computers. Intel was the most proficient in this area and came out with a range of processors from 66 MHz-166 Mhz. These processors are also now starting to become obsolete. Todays computers come equipped with 400-600 Mhz processors that can multi-task at an alarming rate. Intel has just started the release phase of it’s new Pentium III-800MHz processor. Glenn Henry is
computer. The electronic computer has been around for over a half-century, but its ancestors have been around for 2000 years. However, only in the last 40 years has it changed the American society. From the first wooden abacus to the latest high-speed microprocessor, the computer has changed nearly every aspect of people’s lives for the
