TEXT
WHAT IS A COMPUTER?
A computer system is a combination of five elements: hardware, software, people, procedures, data /information. Hardware can be defined as the mechanical, magnetic, electronic, and electrical devices composing a computer system. Software is the term used to describe the instructions that tell the hardware how to perform a task. Without software instructions, the hardware doesn't know what to do. People, however, are the most important component of the computer system: they create the computer software instructions and respond to the procedures that those instructions present. The basic job of the computer is the processing of information. Computers accept information in the form of instructions called a program and characters called data to perform mathematical and logical operations, and then give the results. The data are raw material while information is organized, processed, refined and useful for decision-making. Computers are used to convert data into information. They are also used to store information.
