Un it 1: Introduction to computer systems. The difference between data and information is that data is information in a special form ready to be processed by a computer. Information can be text or a picture Anything that has a meaning to a person is information. A computer is anything that can process data.
An example of a computer is a laptop or PC CPU, Central Processing Unit. The main processing chip of a computer. The central processing unit is a chip inside a computer, which processes the data going in and out of a computer system. In most CPUs, this task is divided between a control unit that directs program flow and one or more execution units that perform operations on data. A COMPUTER PROCESSING UNIT As the brains of your computer, a CPU pretty much runs your computer. The CPU allows you to: Operate software.
The more powerful your CPU, the more kinds of applications you ” ll be able to run on your system. If you don’t have enough power in your CPU, the software will run slowly or incorrectly. Speed your computer’s operation. A top-of-the-range CPU will perform tasks more quickly than an older, cheaper processor. The difference in speed can be seen, especially when doing jobs that require multiple calculations. Do high-end design work.
If you are working with graphics or computer-assisted design, a modern, a powerful CPU is essential to manipulate the massive amounts of information found in complex and memory-intensive graphics. Stay ahead of software design. Software development typically has lagged behind processing power. So it usually takes a while before popular software starts to demand more power than CPUs can deliver. The five elements of a computer system are: INPUT: OUTPUT: MEMORY: BACKING STORAGE: CENTRAL PROCESSING UNIT (CPU): The basic concepts and principles of computer systems are: A computer uses binary coding because it only understands ZEROS (0) and ONES (1) If we press a key on a keyboard, the input is changed in to binary by the computer BINARY Literally means “base two,” a number system consisting solely of ones and zeros, upon which almost all computer machine language is based.

“Bit,” the most basic unit in computing, stands for BInary digiT. The term “digital” corresponds with “binary.”.
