Chapter 1: PART IIntroduction to Personal ComputerSoftware• IntroductionYour PC (Personal Computer) is a system, consisting ofmany components. Some of those components, like WindowsXP, and all your other programs, are software. The stuff youcan actually see and touch is hardware.• HardwareThe hardware are the parts of computer itself includingthe Central Processing Unit (CPU) and related microchips andmicro-circuitry, keyboards, monitors, case and drives (hard,CD, DVD, floppy, optical, tape, etc...).Other extra parts called peripheral components ordevices include mouse, printers, modems ,scanners, digitalcameras and cards (sound, color, video) etc...
Chapter 2: ProcessorThe Central Processing Unit,Which is often referred to as the"Processor" is the brain of the computer.The chip that performs the majority ofcalculations and instructions needed tomake your computer run. Without thischip, no other function of the PC ispossible. The processor is attached to themotherboard (Processor slot).• The speed of the CPUThe computers speed or clockrate is integral to its overall design. Thecomputers clock rate is the frequency atwhich it can execute a set of instructions.Computer clock rates are measured inMegahertz (millions of clock ticks persecond). There are two types of speedsthat should be considered whenevaluating the system performance:• Internal clock speed - Is the speed atwhich the processor can obtaininformation within itself, like withinternal cache and registers.(Pentium III 800 MHz. the 800 MHz isthe internal clock speed)• External clock speed - Is the speed atwhich the CPU communicates withcomponents outside itself.
Chapter 3: MotherboardThe motherboard is the maincircuit board inside your PC. Everycomponents at some pointcommunicates through themotherboard, either by directly plugginginto it or by communicating through oneof the motherboards ports.The motherboard is one bigcommunication highway. Its purposeinside your PC is to provide a platform forall the other components andperipherals to talk to each other.• Modern motherboards come withthe following features:• Processor slot : Processor slot is usedfor processor.• Memory banks : Memory banks areused for RAM modules.• AGP slot : AGP slots are used forgraphics accelerators.• PCI slots : PCI slots are used toprovide connectivity for PCI cardssuch as modems and sound cards.• IDE : IDE are used to connect andcontrol IDE devices such as harddrives and CD-ROM drives.• USB ports : USB ports are used toconnect USB devices.• These are just some of the featuresthat a motherboard may have asstandard, some motherboards comewith integrated components such asa sound card, graphics card, modem,NIC (Network Interface Card) andmore.
Chapter 4: RAMRAM (Random Access Memory) is thebasic working memory of your computersystem. A computer used RAM to holdvolatile (Temporary) instructions anddata needed for processing. Volatilesimply means that it is not permanent,which means anything written to RAMwill be loses if the machine loses poweror if its turned off. Another key pointabout RAM is that data stored unit canbe accessed much more quickly thandata retrieved from the hard disk.Theoretically data retrieved from RAM isaccessed 100 to 300 times faster thanthe same information from a hard disk,optical drive, or a floppy. Memory ismeasured in bytes, so youll oftenencounter the terms megabyte (MB) andgigabyte (GB) in describing RAM sizes (amegabyte is a million bytes; a gigabyte, abillion). RAM is something that you donot want to skimp on. You can choose aslower processor, but with RAM youwant as much as you can get.• Types of RAM:
Chapter 5: HardDiskThe hard disk (or hard drive) is the permanentstorage area of your computer. It storesinformation whether the computer is on or off. Ahard drive is a mass storage device found in all PCs(with some exclusions) that is used to storepermanent data such as the operating system,programs and user files. The data on hard drivescan be erased and/or overwritten, the hard driveis classed as a non-volatile storage device whichmeans it doesnt require a constant power supplyin order to retain the information stored on it(unlike RAM).Hard Drive RPM SpeedsYou will often see hard drives advertised as being capable of a certain RPM(Revolutions Per Minute), this figure (as the name suggests) refers to how many timesthe spindle makes a complete 360? turn in any single minute. RPM values range fromabout 5,400RPM to 12,000RPM and above.
Chapter 6: CardVideo CardVGA Card is the one sending the monitorsignal to the monitor.A computer video card is placed in themotherboard, where it transfers videosignals through a cable to your monitor.The sound card is an essentialcomponent in the PC, since it translatesdigital signals into analog audio for yourlistening pleasure. Well, thats true, if youwant to play games or run multimediaapplications in your PC. Otherwise, itmay not be necessary, especially inbusiness environments.Sound Card
Network CardModem CardA device that translates data from yourPC into a form that can be sent to othercomputers over regular phone lines.The modem also receives signals fromother computers and converts it intosomething your computer canunderstand. A modem is the devicemost home computers use to connectto the Internet.A network interface card(NIC) is a device thatallows computers to be joined together in aLAN, or local area network. Networkedcomputers communicate with each other usinga given protocol or agreed-upon language fortransmitting data packets between the differentmachines, known as nodes .The network interface card acts as theliaison for the machine to both send andreceive data on the LAN.
Chapter 7: Peripherals. KeyboardsThe keyboard is the maininput device for most computers.There are many sets of keys on atypical “windows” keyboard. Onthe left side of the keyboard areregular alphanumeric andpunctuation keys similar to thoseon a typewriter. These are usedto input textual information tothe PC.• MouseMouse is another input device usedin computer. Mouse is a device thatcontrols the movement of the cursoror pointer on a display screen. Amouse is a small object you can rollalong a hard, flat surface. As youmove the mouse, the pointer on thedisplay screen moves in the samedirection. Mouse contain at least onebutton and sometimes as many asthree, which have different functionsdepending on what program isrunning.
• Floppy DriveYou need a floppy drive to read thefloppy. A floppy disk can hold only 1.44megabytes, but it is portable and allowsyou to make copies of your files.• CD-RW• CD - Rom.• MonitorCD writer isused to writeCD. It can alsoused as a CDdrive. CD canbe able to writewith differentformats.Most softwarepackages come inCD format, soyou must have aCD-ROM drive toread them.The information video card sendscontrols which dots are lit up and howbright they are, which determines thepicture you see.Monitor is thedisplay device. Manytimes per second,the video card sendssignals out to themonitor.
Chapter 8: Case And Power Supply8. Computer CaseThe computer case is your computershousing. You need this to store your components, thelargest of which is your motherboard.. Power Supply• The graphic below shows each power cableand its name.The computer power supply is placedinside the computer case generally near the topof the case. It is sometimes necessary to buy amini power supply for some cases are so smallthat they need one. Most computer cases whenbought come with a power supply that is suitedto its case. There are usually power ports on themotherboard for the fans in the case but if not itis possible to buy an adapter that will convertpower from the 4-pin power cable to a fan powercable.
