Parts of Computer ► Motherboard ► CPU ► Memory ► Video

Card ► Power Supply ► Hard Disk ► CD/DVD Rom Drive ► IDE Cable

Motherboard - A motherboard is the central or

primary circuit board making up a complex electronic system, such as a modern computer. It is also known as a main board, baseboard, system board

Motherboard Design

Microprocessor ►A

microprocessor -- also known as a CPU or central processing unit -- is a complete computation engine that is fabricated on a single chip.

Microprocessor Design

Memory ►Memory-

is technically any form of electronic storage, it is used most often to identify fast, temporary forms of storage

Video Card ►A

video card, (also referred to as a graphics accelerator card, display adapter, graphics card, and numerous other terms), is an item of personal computer hardware whose function is to generate and output images to a display.

Video Card Design

Power Supply ►In

a personal computer (PC), the power supply is the metal box usually found in a corner of the case. The power supply is visible from the back of many systems because it contains the powercord receptacle and the cooling fan.

Power Supply Design

Hard Disk ►Hard

Disk Drive (HDD), commonly referred to as a hard drive, hard disk or fixed disk drive, is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.

Hard Disk Design

CD ROM ►CD-ROM

(an abbreviation of " Compact Disc read-only memory") is a Compact Disc that contains data accessible by a computer.

CD ROM Design

IDE Cable ► This

cable will work fine in two-drive configurations, but there is a drawback: it's suboptimal for one-drive installations. These high-speed disk cables really should always have a drive on the physical far end of the cable to reduce noise on the bus, but this cable puts the single drive in the middle

MAINTENANCE

PC Maintenance •

you use your computer more than a few hours per day, we suggest you not to turn off your computer at the end of the day. Instead turn off only the monitor to save electricity. Daily power up and down makes the components exposed to high and low temperature cycles that are not good for the life-time of the components, particularly the critical ones such as hard drives, CPU, and memory. The temperature cycle would result in expansion-shrinking cycle for the components. The life-time of electronic components would be increased if they are run at constant temperature with adequate

PC Maintenance If your area experiences a few times of power outage per year, it is necessary to use a UPS. Sudden power downs while the system is running may cause severe damage to hard drives. • A tape backup and a lock to make systems hard to move are worthy investment for critical data. •

PC Maintenance •

Use your hand to touch and feel the cover of your computer at least once a week. The cover should be at room temperature. If it feels warm there may be a problem! Check to make sure that the cooling fans on the power supply and CPU are working properly. Clean the air pathway on the back of the power supply on a regular basis.

Networking

TOOLS IN NETWORKING ► RJ-45 ► Twisted

pair cable ► Crimp tool ► Ethernet hub ► router ► Network Adapter Card (NIC)

RJ 45 ► Eight-conductor

data cable contains 4 pairs of wires. Each pair consists of a solid (or predominantly) colored wire and a white wire with a stripe of the same color.

Twisted Pair Cable ► Twisted

pair cabling is a form of wiring in which two conductors are wound together for the purposes of canceling out electromagnetic interference (EMI) from external sources, electromagnetic radiation from the UTP cable, and crosstalk between neighboring pairs.

Crimp Tool ► crimps

RJ45 modular plugs. Simply place the plug with the cable in the crimp tool and squeeze the grips together, thus causing the plug to bite into the cable.

Ethernet Hub ► An

Ethernet hub or concentrator is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single segment.

Router ►A

router is a device that determines the proper path for data to travel between different networks, and forwards data packets to the next device along this path.They connect networks together; a LAN to a WAN for example, to access the Internet.
