Components of a Computer
Answer- CPU, Memory and Storage, Peripheral Devices
CPU
Answer- Executes programs' instructions and commands various
components in the computer. Referred to as the "chip".
Memory
Answer- Stores the programs being executed and the data they are using.
I/O Subsystem
Answer- All peripheral devices where long term storage devices are
used.
,Bus
Answer- Permits information to move between each component;
electrical channels that enable communication among the electronic
components
System Unit
Answer- Critical component of all computer based systems; consists of
most of the hardware the computer needs in order to run; comes in a
variety of shapes and sizes.
Internal Components of the System Unit
Answer- Case, Internal Bays, Buses, Ports, Hard Drive, Motherboard,
CPU, CPU Cooler, Memory Module (RAM), Power Supply Unit (PSU),
Expansion Slots/Cards
Parts of the CPU
Answer- Control Unit (CU) - retrieves the instructions and the raw data
that is input and coordinates or controls the sending of those instructions
and data to the ALU
Arithmetic Logic Unit (ALU) - does the actual processing of the data;
completing mathematical calculations and logical operations to process
,the data and converting the input of the keyboard text entry to output
displayed on the screen
System Clock
Answer- Controls the speed at which instructions are processed.
RAM
Answer- Stands for Random Access Memory.
It temporarily stores data before it is processed and sent to your screen
or printer.
It is volatile (means data or information stored disappears when the
computer is turned off or loses power).
You can choose the amount of RAM your computer has.
Types of RAM
Answer- Dynamic RAM (DRAM) - typically called main memory
Static RAM (SRAM) - cache memory and registers
, BIOS ROM
BIOS stands for Basic Input Output System; ROM stands for Read Only
Memory.
Typically stored in ROM chip on the motherboard.
Is software not hardware, ("basic" operating system that runs when the
computer is first turned on).
Runs tests of memory and the CPU and initializes hardware components
so that the actual Operating System can be loaded from the hard disk.
Can't choose the amount or contents.
1st Generation of Computers
Answer- Vacuum tubes, relay switches, the need to program in machine
language
2nd Generation of Computers
Answer- Transistor components, magnetic core memory, smaller size,
easier to program, disk drives and drums, called mainframe computers
