Different features of computer
This document discusses the key features of computers, including processing power, storage, display, operating system, network connectivity, and power. It describes how processing power is determined by the motherboard, processing memory and graphics processing unit. It also explains that computer storage includes the hard drive and removable drives like CDs and USB sticks, and that the display size and resolution can vary between devices. The document outlines how operating systems offer different software compatibility and interfaces, and that most computers have built-in wireless or wired network connectivity options. Finally, it notes that laptop battery life depends on the number of cell packs while desktops require a constant power source.

- 2. WHAT IS COMPUTER? A computer is an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program.
- 4. Processing Power The processing power of a computer is one of its main selling points; it determines the computer's speed and efficiency in handling software. Factors that determine the processing power include the motherboard, processing memory and graphics processing unit. The motherboard is responsible for running all the tasks on the computer. Processing memory space determines how many programs the computer can run at a time. The graphics processing unit is responsible for running all images, video and multimedia on a computer and is a crucial feature for demanding tasks such as video editing and graphics design.
- 5. Computer storage includes the hard drive and removable drives. The hard drive is the computer's main file repository. The speed of a hard drive's rotation also determines how fast the computer can access files and is noted by revolutions per minute, or RPM. Removable drives are secondary forms of storage, including compact discs and memory sticks.
- 6. Display The display is generally separate with desktops and integrated with laptops. Differences in display include size and resolution; higher-end devices usually have a bigger screen size and greater contrast ratio for high definition displays.
- 7. Operating System The operating system is a distinct computer interface. Different operating systems can offer completely different sets of software and program compatibility. For example, the native Internet browser for Windows is Internet Explorer; Safari is the standard for Mac-based computers. Despite having the same basic functionality, each program differs in user interface and task efficiency.

- 9. Powe r Laptop computers are largely dependent on the battery for power. The battery differs in the number of cell packs; a greater number of cell packs usually means that the laptop can last on the battery alone for a longer period of time. For desktop computers, the power source typically has to be connected to an outlet at all times.
