PC INSTALLATION

Preparation
Before assembling the PC there are some things that need to be prepared for
do the assembly with the efficient and effective, namely:

• Documentation PCs or components (including the information admonitions).
• containers to put the nut during installation.
• appropriate screwdriver.
• Paper and pen to take notes or draw diagrams or information from another PC as a comparison in the PC assembly.
• enough space to work (with good lighting).
• antistatic elbow protector (if any).
• Make sure the power is not connected to a power source.

Once these things above have been prepared, then we can begin assembling
by considering:

Monitor

Monitor is one output unit for displaying results  processing files or data. There are 3 types of monitors are now many  used, namely: the type of CRT (Catode Ray Tube), LCD and Plasma. Kind - kind of monitor that ever existed:

•  Monochrom monitor (MDA)                               : text & graphics (CRT) 
• Monitor Color Graphics Adapter (CGA)             : color & RGB graphics (CRT) 
• Monitor Enhanced Graphics Adapter (EGA)        : 640x480 resolution (CRT) 
• Monitor Video Graphics Adapter (VGA)             : 640x480, 800x600 (CRT) 
• Monitor Super Video Graphics Adapter (SVGA) : 800x600, 1024x768 (CRT)  
• Monitor Liquid Crystal Display (LCD): higher resolution

Keyboard

The keyboard is one of the input devices are often used, with technology develops further on the PC keyboard is also increasingly developed. There are 4 types of keyboard is the most commonly used are:

1. Original PC or XT keyboard (83 keys) 
2. AT original keyboard (XT + Sysreq for OS / 2 + 10 function keys) 
3. 101-107 key PS / 2 keyboard (AT + function keys F11 and F12) 
4. 79 Keyboard, 82 keys for Notebook (Laptop)

The big difference between XT and AT keyboards are:

• put XT keyboard microprocessor inside the keyboard,
• AT keyboard, a microprocessor is assumed to be on the mainboard.

CD-ROM, DVD-R (RW) DRIVE

Speed ​​CD-ROM and CD-RW varied from 4X, 8X, 24X to 56X. At first CDROM data transfer speed of 150 Kb / s. So-speed 52X CD-ROM has the ability to transfer data 52 X 150 Kb / s = 7800Kb / s. Interface used is usually IDE (Integrated Drive Electronics). While the DVD-ROM drive is famous for his ability to read the disk format to 4.7 GB capacity than CD-ROM that only a maximum capacity of 720 MB.

Storage Media CD-R (Compact Disc Recordable) and CD-RW (Compact Disc Recordable and rewritable), capacity up to 100MB 720Mb, while DVD-R (Digital Versitile Disc-Recordable) and DVDRW 4.7 GB up to 17GB (double-sided, dual layer)

Sound Card

Serves to produce the sound of the computation performed by
computer, and the results can be heard using speakers. In
it there are some important components are: DSP (Digital Signal
Processor) which functions to handle most computing
associated with sound. DAC and ADC (Digital to Analog Converter) which
processing both incoming voice or sound from the computer,
MIDI and some others such as line out connector,

Hard disk (HDD)

Hard drive is a type of disk that is fixed, generally made of materials or disc-shaped metal plate. A hard drive typically consists from more than one plate or plates are coated with iron oxide. These plates called platters, each platter consisting of 2 sides. Because structure consisting of several disks, the disk has a capacity large storage. In addition it is also very high-speed hard disk with round 3600, 4500, 5400, 6300, 7200, 10000, 12000 rpm so acces data is also very fast. Some types of hard drives on the market that is hard drive used for laptops and PCs. PC hard drive technology that many outstanding currently

VGA Card

Is a link between the CPU with Monitor. Type VGA card:

• Card Monochrom used to monitor the appearance monochrom black / white or green in general. This card is only 8 bits. 

• Color Graphics Adapter Card is used for CGA monitors. This Card can be used two kinds of monitors, since this card can we change of CGA into monochrom and vice versa 

• Enhanced Graphics Adapter Card is used for EGA monitor, card EGA equal to the difference found on the CGA card text displayed, EGA is more subtle than CGA. 

• Video Graphics Adapter Card is used for VGA and SVGA 
• SVGA card is used for VGA or SVGA monitor. SVGA to divided into several types:

Memory

Some types of memory:

• EDO RAM

• SDRAM (Synchronous Dynamicc RAM)

First released, SDRAM is still struggling in the working frequency of 66 MHz, then grew to 100 MHz and 133 MHz final. Width The transferred data bandwidth range from ± 800 Mb / s (PC 100). Now for capacity ranging from 16 to 512 Mb with the number of pins = 168. Figure 2. 16. Memory SDRAM

• DDR SDRAM (Double Date Rate SDRAM)

A DDR SDRAM module consists of 184 pins which have a data point 64 bits. Physically DDR has only one hole on the pin. So that distinguishes it from SDRAM. All kinds of good DDR PC 1600, 2100, 2700, 3200 have the same number of pins. Excess DDR is to have technology that can improve data throughput Memory 2 x faster than SDRAM, because work on the buses 200 and 266 MHz. Figures for 1600/2100 on DDR PC obtained from the calculation as follows:

Proceccor

 PROCECCOR

The processor is the brain or engine of a PC, sometimes called microprocessors or even central processing unit (CPU), which perform calculation (ALU function) and the processing system. 

When we mention the word "processor", it often is imagined then the image processor manufacturers, such as Intel, AMD, VIA / Cyrix and others. Then followed by a series of product output and information about the speed, such as the Pentium 4 to 2.4 GHz,
-AMD 64 Athlon 3200 +, Pentium-M Centrino, 2.0GHz Celeron, Cyrix III-
600MHz and others.

 
There are 2 class processor that was circulated at today's consumers, namely:

Motherboard

The motherboard is the board where the components of computer plugged and can be interconnected. Mainboard types are much once, but the quality of this motherboard is determined by the chipset embedded in it like: Gigabyte, Intel, SIS, NVIDIA nForce, VIA, and other forth.

Power Supply

Cassing and Power Supply
Cassing is a place of components - components that will be our raft. The casing consists of a wide - range of forms including:
a. Cassing Desktop
b. Cassing Tower
c. Cassing Slim

 

Power Supplay an energy source for a computer
function convert AC current into DC. Type of power supplay for PC in the market for computer assembly there are 2:

Computer Architecture

Computer Architecture
There is no specific provision about how to structure a computer system. Every expert and designer of computer architecture have their respective views. However, to simplify we understand the components and functions of each hardware component computers, we need to have general knowledge about the structure of the system computer
