3.  A case that contains electronic components of the computer used to process data.  Available in variety of shapes and sizes.  Is made of metal or plastic.  Protects the eternal parts.  Electronic components and storage devices are part of the system unit.

4.  Main circuit board of the system unit.  Many electronic components attached to motherboard  Other components built into.

5. I. Interprets and carries out the basic instructions that operate a computer. II. Various functions preformed by the processor extend over many separate chips and often multiple circuit boards. III. Contain a control unit and an arithmetic logic unit. IV. Those two work together to perform processing operations

6.  The component of the processor that directs and coordinates most of the operations in the computer.  Interprets each instruction issued by a program and then initiates the appropriate action to carry out the instruction

7.  Another component of the processor  Performs arithmetic, comparisons, and other operations.  Arithmetic operations include basic calculations such as addition, subtraction, multiplication and division.  Depending on results of comparison, different actions may occur.  Comparison operations involve comparing one data item to another to determine weather its bigger or smaller then the other item

8.  A machine cycle, also called a processor cycle or a instruction cycle, is the basic operation performed by a central processing unit (CPU).  it takes a series of steps each time the CPU executes an instruction  Each machine cycle results in the execution of one machine instruction

9. Registers are local storage areas within the processor that are used to hold data that is being worked on by the processor Most operations are done on registers the processor can't directly perform arithmetic in memory The width (in bits) of the processor's registers determine how much data it can compute with at a time you want to add 1 to a memory location, the processor will normally do this by loading the initial value from memory into a register

10.  Most first-generation PCs did not keep track of dates and times  System time is measured by a system clock, which is typically implemented as a simple count of the number of ticks that have transpired since some arbitrary starting date, called the epoch  System time can be converted into calendar time  Library routines are also generally provided that convert calendar times into system times.

11.  Intel AMD  right mouse click on the 'My Computer icon. Click properties and it will give u some info on ur comp, including ur processor. p.s welcome to tsg

12.  In electronic systems, a heat sink is a passive heat exchanger component that cools a device by dissipating heat into the surrounding air.  A heat pipe or heat pin is a heat-transfer device that combines the principles of both thermal conductivity and phase transition to efficiently manage the transfer of heat between two solid interfaces.  As opposed to air cooling, water is used as the heat conductor. Water cooling is commonly used for cooling

13.  Parallel computing is a form of computation in which many calculations are carried out simultaneously  Parallel computers can be roughly classified according to the level at which the hardware supports parallelism  Parallel computer programs are more difficult to write than sequential ones.

14.  A socket on the motherboard that can hold and adapter card.  The adapter card is a circuit board that enhances functions of a component of the system unit and or provides connections to peripherals  A peripherals is a device that connects to the system unit and is controlled by the processor and that computer

15.  Also called and adapter card.  It’s a circuit board that enhances functions of a component of the system unit or provides connections to peripherals.  Sometimes all functionality is built into the adapter card.  With others a cable connects the adapter card to a device.

16. o A thin credit card- sized device that adds memory, storage, sound, fax/modem, network and others. o Because of the small size, some consumer electronics such as digital cameras use them.

18.  Four special purpose parts are:  MIDI- special type of serial port that connects the system unit to the music instrument such as electronically key board.  SCSI- A special high speed parallel port called a SCSI port allows you to attach SCSI pronounced skuzzy peripherals such as disk drives and printers  IrDA- some devices can transmit data via inferred light waves for these wireless devices to transmit signals to a computer both the computer and devices must have IrDA boards.  Bluetooth- An alternative to IrDA Bluetooth technology uses radio waves to transmit data to regular devices unlike IrDA the Bluetooth devices do not have to be realigned with each other.

19.  These bites transfer internally within the circuitry of the computer long electrical channel each channel is called a bus allows the various devices both inside and attached to the system unit to communicate with each other.  Busses transfer bits from input devise to memory from memory to processor from processor to memory from memory to output storage device.  The data bus transfers actual data  Address bus- transfer information about where the data should reside in memory  The size of a bus called the bus width determines number of bits that a computer can transfer at one time.  Word sizes is the number of bites the processor can intercept an execute at a certain time.

20.  PCI Bus (Peripheral components interconnection bus)  Accelerated Graphics Port (AGP)  Universal serial bus (USB)  PC card Bus

21.  Opening inside the system unit in witch you can install additional equipment.  Different from a slot.  Drive bays typically hold disk drives.  The types of drive bays:  External drive bays  Internal drive bays

22.  Is the component of the system that converts the wall outlet AC power to DC power.  AC adapters witch is a external power supply one end of the AC adapter plugs into the wall the other attaches to the peripheral.  Built into the power supply is a fan that keeps the power supply and other components of it cool.
