Computers and How They Work
Why is it important to know how a computer works? Easy, if you don't, it will be hard to control. Computers were never built to control us even though that is how it appears. Their creation was just another tool God gave man to use to benefit society. What can you do to learn more about computers? I have an easy answer. Just read, and use computers more. They are not that hard and with time you too can become the master over this tool.
Computers, the ones we know and love have not been around all that long. The first home personal computer was not sold until 1977. We have come a long way since then. Did you know that in 1983 there were approximately 2 million personal computers in use in the United States. However just 10 years later in 1993 the number had jumped to more than 90 million.
Computers, today are small, fast, reliable, and extremely useful. Back in 1977 that really was not the case. However, they both operated in basically the same way. They both receive data, stored data, processed data, and then output data similar the the way our own brain functions. This article deals with those 4 functions: Memory, Processing, Input, and Output.
MemoryLets look at computer memory first. The function of storage in a computer comes in many different sizes, types and shapes. However there are two basic categories: short-term and long-term. A typical computer contains numerous types of memory including RAM, ROM, virtual, cache, and various long-term storage devices. Each type of computer memory serves a specific function and purpose.
Computer memory is measured in bytes. A single byte is made up of a series of 1's and 0's normally traveling in pairs of eight. These eight 0's and 1's are the way the computer communicates and stores information. With each keystroke or character a byte of memory is used. In another article you will learn more about bits and how the computer thinks
