|
How do the devices in a computer communicate with the CPU?
|
By being installed directly on the system board, linked to it by a cable connected to a port on the system board, or indirectly linked to it by expansion cards.
|
|
|
What is the most important component of the computer's electrical system?
|
The power supply
|
|
|
Volatile Memory
|
Needs a continuous supply of electrial power to hold data or software stored in them. RAM is volatile memory.
|
|
|
What are capacitors used for?
|
To smooth out the uneven flow of electricity through a circuit.
|
|
|
Nonvolative Memory
|
Memory that holds data permanently. ROM chips are nonvolatile memory
|
|
|
Tranistor
|
An electronic device that can serve as a gate for an electrical signal; can amplify the flow of electricity; basic building block of an integrated circuit that is used to build a microchip.
|
|
|
What major components are found on the system board?
|
The CPU, chip set, RAM, Cache memory, buses, expansion slots, Flash BIOS, CMOS chip, and electrical system.
|
|
|
What are some of the features of the ATX board?
|
Developed by Intel for Pentium systems, has a power-on switch that can be software enabled, uses a single P1 power connection.
|
|
|
What are the basic electrical components in a PC?
|
Transistors, Capacitors, Diodes, and Resistors.
|
|
|
What are some of the features of the Baby AT board?
|
Smaller verison of AT, uses P8 and P9 power connections, measures 33cm x 22cm.
|
|
|
What are some features of the AT systems board?
|
Oldest type of board still commonly used today, uses P8 and P9 power connections, and measures 30.5cm X 33cm
|
|
|
Capacitor
|
an electronic device that can hold an electrical charge for a period of time.
|
|
|
What are the two most popular system boards?
|
The AT and the ATX.
|
|
|
How does electricity travels over the system board?
|
On buses, each bus has wires or lines designated to carry voltage.
|
|
|
What is the System board?
|
The largest and most important circuit board inside the computer that houses the CPU.
|
|
|
Diodes
|
semiconductor device that allows electricity to flow in only one direction.
|
|
|
RAM (Random Access Memory)
|
Provides primary storage.
|
|
|
Resistors
|
An electronic device that limits that amount of current that can flow throught it.
|
|
|
Power Supply
|
Converts electricity and reduces it to a voltage that the computer can handle.
|
|
|
Primary Storage
|
Temporary storage that the CPU uses; much faster than permanent storage; Temporarily hold both data and instructions while it is processing them.
