- 2. COMPUTERS A. Is a device that can be instructed to carry out arbitrary sequences of arithmetic or logical operations automatically. B. Is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. C. Programmable electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations, all under the control of SOFTWARE.
- 3. CHARACTERISTICS A. It responds to a specific set of instructions in a well-defined manner. B. It executes pre-recorded list of instructions (program)
- 4. CHARACTERISTICS A. SPEED No human being can compete to solving the complex computation, faster than the computer. B. ACCURACY Since it is programmed, it will always give accurate results. C. STORAGE Can store mass storage of data with appropriate format. D. DILIGENCE Can work for hours without any break and creating error. E. VERSATILITY Can perform completely different type of work at the same time (multi-tasking). F. NO IQ Does not work without instruction. G.

- 12. PARTS OF COMPUTERS 1. CENTRAL PROCESSING UNIT (CPU) Carries out arithmetic and logical operations. Electronic Circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. INTERNAL PARTS
- 13. PARTS OF COMPUTERS 2. MEMORY Is any physical device capable of storing information temporarily or permanently. For example, Random Access Memory (RAM), is a volatile memory that stores information on an integrated circuit used by the operating system, software, and hardware. INTERNAL PARTS
- 14. PARTS OF COMPUTERS 3. HARDDRIVE Is a non-volatile memory hardware device that permanently stores and retrieves data on a computer. A hard drive is a secondary storage device that consists of one or more platters to which data is written using a magnetic head, all inside of an air-sealed casing. INTERNAL PARTS

- 19. PARTS OF COMPUTERS 4. TOUCH SCREENS A display screen that serves as an input device through multi-touch gesture with stylus or fingers. PERIPHERAL DEVICES OUTPUT DEVICES
- 20. PARTS OF COMPUTERS 5. MONITOR Or video display terminal (VDT) and video display unit (VDU), a monitor displays video images and text. It is made up of circuitry, a screen, a power supply, buttons to adjust screen settings, and casing that holds all of these components. PERIPHERAL DEVICES OUTPUT DEVICES
- 21. PARTS OF COMPUTERS 6. SOUND CARD referred to as an audio output device, sound board, or audio card. Is is an expansion card for producing sound on a computer that can be heard through speakers or headphones. PERIPHERAL DEVICES OUTPUT DEVICES
- 23. A computer or array of computers that act as one collective machine capable of processing enormous amounts of data. A supercomputer could be made up of 10, 100, 1000, or more computers, all working together.
- 28. As of 2016, the largest supercomputer is the Sunway TaihuLight in China. It consists of 40,960 RISC processors, each with 256 cores, totaling 10,649,600 cores. The Sunway TaihuLight is capable of 93 petaflops of processing power and uses a custom operating system, called Sunway RaiseOS.
- 29. TYPES OF COMPUTER An ultra high-performance computer made for high-volume, processor-intensive computing. A data processing system employed mainly in large organizations for various applications.
- 30. USES OF MAINFRAME Bulk data processing, process control, industry and consumer statistics, enterprise resource planning, and financial transaction processing.
- 31. Computer that is smaller, less expensive, and less powerful than a mainframe or supercomputer, but more expensive and more powerful than a personal computer.

- 42. GAMING CONSOLE A specialized desktop computer used to play video games. The two most popular consoles are Sony's PlayStation and Microsoft's Xbox.
- 43. NETBOOK Is a small, light, low-power notebook computer that has less processing power than a full-sized laptop designed primarily for accessing Internet-based applications.
- 44. LAPTOP often called a notebook or "notebook computer", is a small, portable personal computer with a "clamshell" form factor, an alphanumeric keyboard on the lower part of the "clamshell" and a thin LCD or LED computer screen on the upper part, which is opened up to use the computer.
- 45. PERSONAL DIGITALASST. a handheld device that combines computing, telephone/fax, Internet and networking features. A typical PDA can function as a cellular phone, fax sender, Web browser and personal organizer. PDAs may also be referred to as a palmtop, hand-held computer or pocket computer.
- 46. TABLET A tablet computer, commonly shortened to tablet, is a portable PC, typically with a mobile operating system and LCD touch screen display processing circuitry, and a rechargeable battery in a single thin, flat package. Tablets, being computers, do what other personal computers do, but lack some I/O capabilities that others have.
- 47. MOBILE TABLET Is a line of tablet computers designed, developed and marketed by Apple Inc., which run the iOS mobile operating system. This device for "browsing the web, reading and sending email, enjoying photos, watching videos, listening to music, playing games, reading e-books and more.

- 49. CALCULATOR Is a device that performs arithmetic operations on numbers. The simplest calculatorscan do only addition, subtraction, multiplication, and division. More sophisticated calculators can handle exponent ial operations, roots, logarithm s, trigonometric functions, and hyperbolic functions.
- 50. SOUND & NAVIGATION Vehicle audio is equipment installed in a car or other vehicle to provide in-car entertainment and information for the vehicle occupants. Once controlled from the dashboard with a few buttons, they can now be controlled by steering wheel controls and voice commands.
