CPU
CPU (Central Processing Unit - ცენტრალური გადამამუშავებელი ერთეული) also called the Microprocessor or “The Brain” of the Computer.
Processor speed: The speed at which a microprocessor executes instructions. This is usually measured in megahertz (MHz). -სიჩქარე რითაც მიკოპროცესორი ასრულებს ოპერაციებს

Computer Memory
RAM (random access memory) stores data that is processing. This type of memory is erased when the computer is turned off.
ROM (read only memory) contains special instructions for the computer to operate.

Storage
Hard Drive
1 Terabyte and upwards today
As low as 256 KB less than 30 years ago.
(that is more than a million times greater capacity today!)
CD-ROM
600-700 MB
DVD-ROM
4 GB - Red Laser,
27 GB- Blue Laser
Flash Drives
From 4 GB up to 100+ GB, including high end of 1 TB.

Video Cards
Video cards plug into the motherboard and are used to display video.
VRAM is video memory that enhances the refreshment rate of the image.
Video cards have chipsets that can increase the speed of video display.

Pixel

Resolution
Resolution refers to the number of pixels (picture elements) in the monitor image.
Increased resolution uses more computer resources but increases the visual clarity of the display.

Resolution
Screen resolution is measured in pixel per inch (ppi), and printer resolution is measured in dots per inch (dpi).
Computer screen resolution is approximately 72 ppi.
