and ADAPTER CARD
), (3 Basic Components of Motherboard
- PROSESSOR SLOT
Processor slot is a slot on the motherboard that houses a CPU and forms the electrical interface with the CPU.
- MEMORY SLOTS
Memory slots are slots on the motherboard that hold memory modules.
- ADAPTER CARD SLOTS
Expansion slots on the motherboard that can hold adapter card.
Consists of the electronic components that store instuctions waiting to be executed by the processor.
, DEFINITIONMotherboard is a main circuit board of the system unit, which has some electronic components attached to it and others built into it.
An electronic component on a computer's motherboard that interprets and carries out the basic instuctions that operate the computer.
Iterprets and carries out the basic instructions that operate a computer.
, 2 BASIC COMPONENTD OF PROCESSOR
- CONTROL UNIT (CU)
Funtion: Directs and coordinates most of the operations in the computer.
- ARIMETIC LOGIC UNIT (ALU)
Funtion: Performs arithmetic and logical operations.
, MACHINE CYCLE
4 BASIC OPERATIONS IN MACHINE CYCLE
- FETCH: Fetches the instuctions or data item from memory.
- DECODE: Decodes the instuctions into commands and sends the instructions to the ALU.
- EXECUTE: Executing the commands and if necessary.
- STORE: The results are stored in memory.
, EXAMPLE STEPS IN MECHINE CYCLE
- The control unit fetches the math problems instuctions and data from memory.
- The control unit decodes thye math problems instructions and sends the instructions and data to the ALU.
- The ALU performs calculations on the data.
- The results of the math problems are stored in memory.
, FUNTIONThe functions of the motherboard are:
Holds many components of the system.
Provides connectors for other peripherals.
To store data and instructions waiting to be executed and the results of processing the data(information).
, TYPES OF MEMORY
1.Also called main memory.
2.Can be read from and writteb to by processor.
3.Holds data or programs that are currently being used by the processor.
4.Assembled on a small circuit board called memory module which is plugged onto the memory slots.
DEFINITION: Will lost its cintents when the power is turned off or interrupted.
EXAMPLES: SRAM(static RAM), DRAM(dynamic RAM), MRAM(magnetoresistive RAM).
- NON VOLATILE
Description(ROM):1.Data is prerecorded for read only and cannot be removed.
2.Contain a small startup program(BIOS) which is used to boot the computer.
Exists as a chip on the motherboard.
DEFINITION: Does not lose its contents even when the computer power is turned off.
EXAMPLES: PROM(Programmable ROM), EPROM(Erasable Programmable ROM), EEPROM(Electrically Erasable Programmable ROM)
Any data and instructions entered into the memory of a computer.
Any hardware component that allows users to enter data and instructions into a computer.OUTPUT
Data that has been processed into a useful form.
Any type of hardware component that conveys information to one or more people.
, INPUT DEVICESKEYBOARD
An input device that contains keys users press to enter data and instructiond into a computer.
Input device that allows a user to control a pointer on the screen.
A touch sensitive display device
You touch a stylus or digital pen on a flat surface to write, draw, or make selections.
Input device that directs movements and actions of on screen objects.
Mobile device that alloes users to take pictures and store the photigraphed images digitally.
the process of entering input by speaking into a microphone.
the process of entering any sound into the computer such as speech, music, and sound effects.
process of capturing full motion images and storing them on a computer.
, OUTPUT DEVICESDISPLAY DEVICE
an output device that visually conveys text, graphics, and video information.
an output device that produces text and graphics on a physical on a physical medium such as paper.
AUDIO OUTPUT DEVICE
a component of a computer that produces music, speech, or other sounds.
a device that takes the text and images displaying on a computer screen and projects them on a larger screen so that an audience can see the image clearly.
, INPUT AND OUTPUT DEVICES
storage holds data, instruction and information for future use.
the fhysical material on which computer keeps data, instructions and information.
, TYPES OF STORAGE MEDIAMAGNETIC STORAGE
Uses different patterns of magnetization on a magnetically coated surface to store information.OPTICAL DISC
Store information in deformities on the surface of a circular disc and read this information by illuminating the surface with a laser diode and observing the reflection.FLASH MEMORY
Data is retained in non volatile memory chips and contain no moving parts. Small, lightweight and highly reliable.
