A Computer is a programmable device or machine that is capable of performing arithmetic and logical operations both automatically, simulteanously and sequentially in a given or instructed direction. It is also known as multi-data processor such that it can process, store and retrieve data of various kinds as directed by the user.
Computer Science is simply the study of computers and computing systems. Computer scientists deal mostly with software and software systems; such as the computing theories, design, development, and application.
The earliest discovery of computer science was based on calculations. Calculating fixed numerical tasks with Abacus, aiding in computations such as large multiplication and division. Wilhelm Schickard designed and developed the first standard mechanical calculator in 1623. And In 1673, Gottfried Leibniz developed a digital version of the mechanical calculator, called the Stepped Reckoner.
Charles Babbage started the design of the first automatic mechanical calculator, called Difference Engine, in 1822, which eventually gave him the idea of the first standard programmable mechanical calculator, called Analytical Engine machine in 1834.
The early computers was based on calculations and has evolved into Modern Computers with many functions and uses. The major composition of modern computers are:
3. Human ware,
4. Bridgeware and
Hardware is regarded as the physical components of the computer system that can be seen and touched through which the user communicate with the computer. Examples are:
3. Monitor among others.
Software is the untouchable part which controls the activities or functions of the computer. Such as:
1. System Software,
2. Application Software and
3. E-Accessory software
Advantages and Functions of Computer Science:
2. Ease of Operations
3. Ease of Data sharing
5. Enhances the security system
6. It accept commands as input as given by the user.
