ماعندي الا حقت الاسبوع الثاني

OPEN-ENDED
all computer systems have a system unit for microcomputers there are six basic types :
1)
desktop system unit : typically contain the systems electronic components and selected sec ondary storage devices . input and output devices such as a mouse , keyboard and monitor
2-media center system units : blur the line between desktop comput-ers and dedicated entertainment devices .
3-notebook system units: are portable and much smaller . these system units contain the electronic components selected secondary storage
4-netbook system units: are similar to notebook system unit they are however smaller less powerful and less expensive
5-tablet PC system unit: were similar to notebook system unit since the introduction of apples ipad however the definition
6-handheld computer system unit : are the smallest and are designed to fit into the palm of one hand

2)
1-analog: or continuous signals that vary to represent dif ferent tones pitches and volume computers however can recognize only digital electronic signals
before any processing can occur within the system unit a conversion must occur from what we understand to what the system unit can electronically process

3)
sockets: provide a connection point for small speciazed electronicparts called ships
Chips: consist of tiny circuit boards etched onto squares of sandlike material called silicon
Carrier packages : these packages plug either directly into sockets on the system board or onto cards that are then plugged into slots on the system board .
Slots : provide a connection point for specialized cards or circit boards
Bus lines : provide pathways that support commu-nication among the various electonic components that are either located on the system board or attacher to the system board

4)In a microcomputer system the central processing unit (CPU) or processor is contained on a single chip called the

5) offers a combination of the features of ram and rom like ram it can be updated to store new information like rom it does not lose that information when power to the computer system is turned off

6) was originally a set of specific hardware and software stan dards developed by intel microsoft and others a generic term that is asso ciated with the ability to plug any device such as a printer or monitor into a computer and have it play or work immediately

7) bus line : also known simply as a bus connects the parts of the cpu to each other
Bus width : a bus is similar to a multilaane highway that moves bits rather than cars from one location to another
System buses : connects the cpu to memory on the system board
Expansion buses : connects the cpu to other components on the system board including expansion slots

8)Four standard ports are
1-VGA(Video graphics adapter) and DVI (Digi -tal Video interface) provide connections to monitors
2-USB (universal serial bus ) widely used to connect keyboards mice printers and storage devices one port can connect several devices to system unit
3-FireWire provides high-speed connections to spe-cialized fireWire devices such as camcoputers and storage devices
4-Ethernet high speed networking port that has become a standard for many of today's computers
Specialized ports :
Three specialty ports are S/PDIF for high-end audio and home theater systems high definition multime dia interface for high definition digital audio and video , and MIDI for digital music
Legacy ports: have largely been replaced by faster more fleible ports such as the universal serial bus (USB)
Cables : are used to connect external devices to the system unit ports

9) power supply units convert AC to DC they are located within the desktop computer 's system unit AC adapters power notbook computer and tablet PCs and recharge batteries
