Internal Hardware
Motherboards
main printed circuit board.
Contains buses, or electrical pathways found in a computer.
Buses allow data to travel among the various components
accommodates CPU, RAM, expansion slots, heat sink/fan, BIOS chip, chip set, sockets, internal and external connectors, various ports, and buses
System Unit
Tower type case
Desktop type case
CPU
performs actual processing of data, according to instructions from programs.
Data and programs are stored in primary and secondary memory and moved to and from CPU as required.
Signals representing data and instructions, travel between system components along electronic pathways, called buses
brain of the computer
Intel/AMD microprocessor
general purpose processor that performs data manipulation and/or transformation functions including computations, comparisons and data movement.
Arithmetic Logic Unit (ALU) - arithmetic and logical operations Control Unit (CU) - controls data movement and execution of instructions
Registers - small high speed storage areas
Memory
data storage
Primary memory
RAM & volatile
hold data and instructions during processing
Small size, Great speed, Shock and temperature resistant
temporary
Secondary memory
High capacity & non-volatile
provide permanent long term storage
Read-only memory (ROM)
Cache
store the most frequently used data.
Hard disk, floppy disks and tapes
store data using magnetic
read or write information to magnetic storage media.
be fixed or removable
Optical Drive: CD’s, DVD’s & BlueRay Disk (BD’s) store data that are detectable by laser light.
SSD
no moving parts, make faster access to data, higher reliability, reduced power usage
Flash drive
removable storage device that connects to a USB port.
requires no power to maintain the data.
IDE, EIDE, PATA, SATA, eSATA,SCSI
Adapter Cards
increase the functionality of a computer by adding controllers for specific devices or by replacing malfunctioning ports.
Sound adapter and video adapter
USB, parallel, and serial ports
Network Interface Card (NIC), wireless NIC, & modem adapter
expansion slots
PCI
AGP
PCI-E
