COMPUTER HAS FOUR PARTS - HARDWARE, SOFTWARE, DATA, USER, an electronic device that shows pictures often look similar to televisions. - MONITOR, allows a person to enter symbols like letters and numbers into a computer. - Keyboard, It is the main input device for most computers. - Keyboard, Types of Keyboard - QWERTY, DVORAK, COLEMARK, DVORAK, COLEMARK, is an input device that is most often used with a personal computer. - MOUSE, along a flat surface can move the on-screen cursor to different items on the screen. - MOUSE, Items can be moved or selected by pressing thebuttons (called clicking) - MOUSE, Different type of mouse - Mechanical Mouse, Optical Mouse, Wired Mouse, Wireless Mouse, Gaming Mouse, Ergonomic Mouse, an external hardware device responsible for taking computer data and generating a hard copy of that data. - Printer, also knows as a “computer chassis”, “tower”, “system unit”, “base unit” or simply “case” and sometimes incorrectly referred to as the “CPU” or “hard drive”, is the enclosure that contains most of the components of a computer. - Computer Case, Also known as PSU - Power Supply, converts mains AC to low voltage regulated DC power for the internal components of a computer. - Power Supply, Also known as GPU - Video Card, allows the computer to send graphical information to a video display device such as monitor, TV, or projector. - Video Card, Video Card Includes What? - processing unit, memory, a cooling mechanism and connections to a display device., An expansion board that enables a computer to manipulate and output sounds. - Sound Card, necessary for nearly all CD- ROMS and have become commonplace on modern personal computers. - Sound Card, enable the computer to output sound through speakers connected to the board, to record sound input from a microphone connected to the computer, and manipulate sound stored on a disk. - Sound Card, also called a Network Adapter or Network Interface Card, or NIC for short - Network Card, acts as the interface between a computer and a network cable. - Network Card, to prepare, send, and control data on the network. - Network Card, sometimes alternatively known as the mainboard, system board, planar board or logic board, or “mobo” - Motherboard, is the main printed circuit board (PCB) found in computers and other expandable systems. - Motherboard, What are the sizes of motherboard - Eatx, Atx, Micro-Atx, Mini-tx , formerly also referred to as a central processor unit - CPU, the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical and input/output operations of the system. - CPU, also called optical drive - Optical Disk Drive, Allows you to use CDs, DVDs, and Blu-ray discs to listen to music or watch a movie. - Optical Disk Drive, Refered as Random Access Memory - RAM, is a form of computer data storage. Allows data items to be read and written in roughly the same amount of time regardless of the order in which data items are accessed. - RAM, Refered as Read- only memory - ROM, is a type of storage medium that permanently stores data on personal computers and other electronic devices. - ROM, it cannot be change; it is permanent and non-volatile, meaning it will also hold its memory even when power is removed. - ROM, It is volatile; it is lost when power is removed. - RAM, is a data storage device used for storing and retrieving digital information using rapidly rotating disks (platters) coated with magnetic material. - Hard Disk Drive (HDD), retains its data even when powered off. - Hard Disk Drive (HDD), is a new generation of storage device used in computers. - Solid State Drive (SSD), store data using flash-based memory, which is much faster - Solid State Drive (SSD), He invented the Mouse - Douglas Engelbart,
