Creating a Computer-Najihah Athar-
What is a computer?A computer is a machine that follows the orders of the user. All computers have four main components which is the arithmetic logic unit (ALU), the control unit, the memory and the input and output devices. These parts of the computer are connected by busses which is a group of wires. Inside these parts are thousands of electric circuits which are turned on and off when the computer is being used. All computers are able to store, retrieve and process data. Computers can range from big to small sizes and fast or slow speed. Anything one computer is capable of doing; the other computer can do too.
MONITOR
•Clear visual display (LED)•Glossy screen-High color saturation, clear sharpness of images and blocks out any reflecting light.•Power saving-Adjust the screen’s brightness to save power.•Polarized 3D monitor-You can view videos in 720p in 3D with 3D glasses (you can get the screen installed separately)
20” screen with HD viewing
The monitor is made out of stainless aluminum so there will be no scratches and little heat conduction.
The screen is a wide (20”) to allow airflow in the computer’s system. This means that wires won’t get heated up. This prevents short circuits.
HD LED light with 800 GB HDD
Webcam that transfers clear videos with no interference
Thin frame more space on the desktop
Clear glass and thin frame to allow comfortable viewing.
LCD Monitor
Has only one main cord for power
SYSTEM UNITPower button
CD Drive
Icons -Battery, Flash drive, Wi-Fi and Bluetooth-
Headphone Jack
Indicates how much battery life there is left
Indicates Wi-Fi strength
CD/DVD Drive USB Jack
Shows which jack each USB is inserted in
Bluetooth icon
Phone/Camera Memory card
Network jacks (for printers etc)Internet cable
Lightweight steel.
SYSTEM UNIT
Features:System Unit- It contains the motherboard, power supply, cooling fans, internal disk drives and memory modules. The system box can’t break down easily because of the high protection inside and out. It can balance the monitor too. The reaction to the order is fast.Motherboard- Handles and supports the advanced computing processes. Since it is the main circuit board for the computer, it is protected by a covering that doesn’t allow dust or anything else to enter. CPU-It is the main chip in the whole computer system because it is where the calculations take place. It has a small fan on top of the CPU to help get rid of heat.Cooler-A cooler is installed under the system box to cool down the system, which Memory-A high memory capacity of 2-32GB RAM
Input and Output (I/O)I/O means any device that transfers data TO or FROM a CPU.Input means when information is put into the CPU. Output means when information from the computer is taken out from the CPU and into the outside world.

Speakers
SPEAKERSFeatures:High Definition Sound, no echoes, no distortion and HD response
The speakers are placed on the system unit for high projection and more space on the desktop.
Built in the system unit
Built-in speakers deliver loud, clear sound with notable bass response and very little distortion.
Sound projection is multiplied because the speakers are in form of small circles and are placed close together. It gives a 360° sound.

Soft keys that make little or no noise when hit
Keys are placed close together so dust won’t enter
Wireless keyboard makes a tidier desktop
The right side has a memo pad where you can type in a to do list or passwords to remember.
Extremely thin. You can change the sensitivity levels.
MOUSE
It is smooth, seamless mouse that can control everything with simple gestures of the hand
Allows fast scrolling
Has laser tracking
Made out of stainless aluminum
Two way power (battery and solar powered)
Wireless. This makes a tidier desktop
Scroll is tap sensitive. This means that you can scroll down with a tap and a drag down (instead of scroll down)
PRINTERScanner-Same resolution quality as the place picture.
Options menu. Print, scan and photocopy
Paper
Inkjet Printer500 sheet input tray
Wireless printer. It is connected by a flash drive installed on the computer.
Resolution: 4800 dpi (dots per inch)
Speed: 30ppm (papers per minute)
MODEM
Converting a computer’s digital signals into specific frequencies is a very important job.The network is a very big place and a good modem is needed.This modem can convert signals in 30-characters per second which is fast. This means that the computer will receive and give more information in a shorter time.The signal can be transmitted easily and decoded to reproduce the original digital data
