System Unit - Case that contains electroniccomponents of the computer used to processdata.

Common components inside the system unit: Processor Motherboard

Memory Ports Power supply Adapter cards; Sound card, modem card, video card

and network card.


7/26

These are the generalcomponents of computers.

Can you give the functionsof each component?

Computer Components

MotherboardThe motherboard is like the nervoussystem of a human being, it connects all

the internal components together. Allcommunication is done over themotherboard.

CaseThe computer is enclosed inside of a case.The case is like the metallic body of a car.It protects the internal components andholds everything in place.

Computer Components

Power SupplyThe power supply provides the correct

electricity for each component.

ProcessorAct like a human brain. All decisions andcalculations are done by the processor. Itexecute computer programs andactivities.

Computer Components

CPU FanTo cool the heat produced by the other

computer components during computerprocessing

Hard DriveBesides storing digital information, harddisk drives also contain all of a computer'soperating data, including the operatingsystem.


11/26

Computer Component

RAMRAM stands for Random Access Memory.It is temporary storage for data. For

instance, when you open Microsoft Word(or any program), it goes into RAMbecause your CPU can get it a lot fasterfrom RAM

Windows

by Microsoft

Windows Macintosh

Hardware

andCustomizability

Highly customizable

Preferred by many becauseof how easy they can be tocustomize. Because of theway their hardware isdesigned, users can replacegraphics cards, RAM chips,

CD drives, motherboardsand other internal hardwareat their discretion.

Less customizable

Most Mac models, on theother hand, are difficult toupgrade apart from RAMand a few other basiccomponents. Mostchanges require a visit to

an Apple store.


14/26

Windows Macintosh

Price Inexpensive

Windows computers areconstructed from a numberof parts from variousmanufacturers

Expensive

Mac computers are lesscustomizable and havegreater hardwarerestrictions


15/26

Windows Macintosh

Software

Availability

Widely Available

Windows is much morewidely used, so moresoftware is available forWindows than for Mac. Thisis the reason that manygamers choose Windows,

because many titles aren'tavailable for Mac if the gamedevelopers don't choose tomake a separate version.

Limited

AvailabilityHowever, there are manyprograms and utilitiesdesigned exclusively forthe Mac operatingsystem.


16/26

Windows Macintosh

Security More likely to Get

Effected withVirusesWindows suffers the mostfrom viruses, spyware,adware and other malicious

software than any otheroperating system.

Less Effected with

VirusesThere are malicious(harmful) programs madefor Mac as well, but Macsaren't infected nearly asoften.


17/26

Windows Macintosh

Operation More steps and

ActionsFor example, Windowsprograms are installed byfollowing an install processwith a number of steps

Programs are uninstalled inWindows via the Add orRemove Programs utility

Less Steps and

ActionsMac applications can beinstalled by clicking anddragging an icon into the"Applications" folder.

Mac users can uninstall aprogram by deleting itsicon in the "Applications"folder..

1. I am the primary source that links your computer processorunit (CPU), your memory and hardware.

2. I provide electricity to all the computer components to befunctioned.

3. I store short term memory. The memory is used to process

current data.4. All the computer programs and activities must go through

me.5. Without me, the CPU can be overheat.6. All the downloaded files and folders are stored in me.

Who am I?
