HARDWARE MOUSE PAD OPERATING SYSTEM APPLICATION SOFTWARE COMPUTER SYSTEM allows the transmission ofdigital data (from computer or other digital devices.) for import data. for printing information( in paper) by usingsoftware. provide to users a simpleand functional way to give orders in the computer, for saving data. used from users to perform useful tasks or projects,such as performvarious calculations,programming,creation and editing text,images,graphics,sound e.t.c. performs programms,saves tasks and projects,manages and controls the hardware computer and generally the functions of computer.Popular operating systems are:Windows Linux,Unix,MacOS,Solaris. executes operations such as addition andlogical coupling neededfor the execution of orders. CONTROL UNIT REGISTERS MEMORY any unit that can save data in binary formand allow their retrieval. Random Access Memory (RAM) Read-only memory (ROM) It is used to temporarily storedata and information that the computer uses to implement its applications. A form of memory that is permanent and is used bythe computer for important information that does not change. Basic input/output system (BIOS) A type of ROM memory used by thecomputer to install basic communication,when the computer is first opened.It alsocontrols and coordinate all the operationsthat needed, until the computeris readyto perform an application or a command ofuser. This is used by the computer ton record and playmusic by converting the analog signal into digital information and back again. a computer case usedfor active cooling andexpel warm air from inside. is used to cool central processing units or graphics processors. a cable with many conducting wires running parallel to each other on the same flat plane. a medium-capacity removable disk storage system. is a disk storage medium composedof a disk of thin and flexible magneticstorage medium. a cable that temporarily connects an applianceto the mains electricity supply via a wall socketor extension cord. translates the data from the computer into a form thatcan be displayed. Also used a bit number that indicates the number of colors and starts from 16 colors and canreach up to 32-bit colors which translated into millions of colors. main board with circuitswhich are connected allthe components of thecomputer.Determine theinternal architecture of thecomputer.Also,suppliespower to all componentseither directly via corridors or indirectly through cables. a flat, usually circular disc which encodes binary data (bits) in the form of pits (binary value of 0 or off, due to lack of reflection when read ) and lands (binary value of 1 or on,due to a reflectionwhen read) on a special material (often aluminium)on one of its flat surfaces. (CD-ROM->650-700MB,(DVD->4,7GB) is a communication system that transfers data between components inside a computer,or between computers. The buses are channels or cable that passes electric signals corresponding to a binary symbol.[0],[1]. a large storage area that is stable and permanent and is used to hold information such as programs and documents.Technically, it is a collection of hard drives are covered by a magnetic material. Inthis written material data using read / write heads. FAN An electrical converter that regulates the electricity used by the computer.Convertsthe alternating current to constant, voltage 0-12Volt.(It also calculated in Watts ) A chip located above the motherboard and is responsible for all the computer operations.The speed of the CPU is measured in Hertzs.(Hertzis one cycle per second.) used for storing data andcommands into the processor.The size of the registers can affect the speed and output ofthe computer. ARITHMETIC LOGICAL UNIT (ALU) OPTICAL DISK(CD-ROM OR DVD DRIVE) BUS MOTHERBOARD includes: directs the flow ofinformation to the CPUand to the memory and control what will be the next instruction to be executed by the CPU.
