2.1.2 SOFTWARE
Software is the step-by-step instructions that tell the hardware how to perform a task. Without software, the hardware is useless. Software is of two types: Systems software and Applications software.
Applications software is the software that can perform useful work on general-purpose tasks while the systems software enables the applications software to interact with the computer and help the computer manage the internal resources.
2.1.3 DATA / INFORMATION
2.1.4 PROCEDURE
Procedures are the steps for accomplishing a result. Some procedures maybe expressed in manuals or documentation.
2.15 PEOPLE
People are the most important part of, and the beneficiaries of, a computer-and-communications system. The whole point of data processing is to benefit people. People of all level and skills, from novices to programmers, are the users and operators of the system. Regardless of the size of the data processing system, data processing personnel will probably be needed to make the system efficient and effective.
For a small organization, there maybe only one or two people in the data processing department. A large system may require literally hundreds or even thousands of personnel. A small business owner who decides to operate a microcomputer will be performing the functions of a complete data processing department.
People and procedures are probably the easiest elements to understand in a computer-and-communications system – although, arguably the most complicated.
