The inner circuit components are silicone objects that are called a semiconductor. There are also a numerous amount of wires that joins in with components this is called the Bus. Where the machine stores data and programs is called the hard. The operating system is when a computer is turned on and searches memory. Examples of operating systems are Windows 98, Windows 8 and Mac. Today’s most popular operating system is Windows 8. Today’s students majoring in the field of computer science will also have to learn the history of the computer. Now, let’s go on to the history of the computer.
The IBM 360 (1964): (Wikipedia) The 360 series pioneered the concept of upward compatibility whereby a user could upgrade from one computer to the next without having to reprogram existing applications. The machine was viewed as an enormous financial gamble, but paid off tremendously as it gave IBM dominance in mainframes which it has never relinquished. Apple II (1977): (wikipedia) The Apple Il was a fully assembled home computer in an attractive case, complete with keyboard, connection to a TV screen, color, memory to 64Kb, and basic interpreter. The machine was to launch the personal computer revolution and vault its founders, Steve Wozniak and Steve Jobs, from garage to glory. IBM PC (1981): (Wikipedia) IBM wasn’t the first nor was it technologically innovative, but IBM’s announcement put computers on the desks of America's economic business scale. By 1985 IBM had manufactured its three millionth PC, and had spawned an entire industry in the process. (Wikipedia)

Apple Macintosh (1984): The Macintosh was far from an instant success, but once Apple got the bugs out and added an internal hard disk, laser printer, and expanded memory, the machine took off. Its ease of use and graphical interface offered an entirely different perspective on computing. (Wikipedia)

The PC Today (2014): The march of technology is relentless and astounding and today’s PC runs rings around its predecessor. Today you can buy a Pentium processor with touch-screen 4GB memory, 750GB hard drive all for approximately $500.
