Since the days of computers the size of rooms and cathode ray tubes, video games have been a hot topic filled with constant innovation and adaptation. What better for adaptation than the one piece of technology that is evolving and changing every hour of every day, the personal computer.…
Hints: (a) Notice that there are no “x” variables in the functions on the left hand side of this…
Early in the years of computers, the then generation had predictions. They saw computers or rather artificial intelligence turn-around how people would relate with each other and their environment. They had a believe of how machines like computers being our drivers, robots doing our chores and functions like voice interface controlling retrieval and storage of data and information. However, it never came to pass because of the difficulty in implementing and carrying out step-by-step logic operation that is provided by digital computers.…
By 2008, PCs were far easier to use than they had been two decades earlier. They had also begun to…
Some professionals in the Information Technology (IT) field might describe the Operating System (OS) of a Personal Computer (PC) as its software brain. Jean Andrews, Ph.D., describes an OS this way: “An operating system is software that controls a computer. It manages hardware, runs applications, provides an interface for users, and stores, retrieves, and manipulates files” (Andrews, 2010). In other words, the OS is the Graphical User Interface (GUI) from which the PC’s operator controls any piece of hardware or software. Before installing an OS, a user must understand the purpose that it serves – why it is important to have an OS. Once understanding what purpose the OS serves to the user, he/ she will understand how this can help to operate and maintain his/ her own computer. Eventually, the user should hope to gain enough knowledge about a particular OS, that he/ she will be able to assist others with installing it on another PC.…
Today in this modern world, computers have made a mark able position in almost everyone’s life. From students to business men, everyone owns a computer. Without a computer, life seems quite impossible. It is the most versatile machine ever been made. Anyone can use a computer according to his or her own desire. For example, a small kid may use a computer to play games or a student may use it as a medium to extract information from the internet, etc. The importance of this machine can be observed in our day-to-day life.…
As our world expands through the growing abilities and applications of computers in our everyday lives, it seems that the role of the computer has been reversed. Before we knew that the computer only understood what we programmed it to understand; however, now the majority of our society is learning more from computers than they are able to input into it. Dumm (1986 p.69)…
The package Truth Tables and Boolean Algebra set out the basic principles of logic. Any Boolean algebra operation can be associated with an electronic circuit in which the inputs and outputs represent the statements of Boolean algebra. Although these circuits may be complex, they may all be constructed from three basic devices. These are the AND gate, the OR gate and the NOT gate. x y AND gate x·y x y OR gate x+y x NOT gate x…
At one point in time there were computers that were nowhere near as intricate like the ones we have learned to love today. Older computers were not as small as the ones we are used to having on our laps today. In fact the first computer ENIAC (electronic numerical integrator and computer), weighed 30 short tons,…

A few years ago, computers were practically unheard of by most people. Today, computers are one of the most powerful tools throughout the world. The world has changed since these machines have come along. They play a huge part in many all of our lives in one way or another. And it’s almost scary to stop and think how much we rely on them on our day-to-day routine. People always tend to seek the easy way out looking for something that would make their lives easier. These machines and tools have given us the ability to do more in less time giving us, at the same time, more comfort. As the technology advances, computers become faster and more powerful. The increased use of these tools, however, would control humans' lives and change the way in which they think.…
a) Speed – A PC can process data at a very high speed. It can process millions of instructions within fraction of seconds.…
Computers were invented many years ago, but we began to use them recently. The technical progress is constantly developing. People always create new computer technologies. The computer has become a part of our daily life. Many people use computers at work, school, and at home, but we have not yet realized the advantages and disadvantages of the computer.…

Computers have gained popularity over the years and everyone at least has one somewhere stashed around their house. We have the need to use computers for everything. Computers have become sort of like a useful household staple that can manipulate any data we want according to a set of instructions. That's how it is, all we have to do is give the computer instructions and it does all the hard work for us.…
