BIT
• (short for "binary digit") is the smallest unit of measurement
used to quantify computer data. It contains a single binary
value of 0 or 1.

BLU-RAY
• Blu-ray is an optical disc format such as CD and DVD. It was developed for
recording and playing back high-definition (HD) video and for storing large
amounts of data. While a CD can hold 700 MB of data and a basic DVD can
hold 4.7 GB of data, a single Blu-ray disc can hold up to 25 GB of data.

BYTE
• A byte is a unit of measurement used to measure data. One byte contains
eight binary bits, or a series of eight zeros and ones. Therefore, each byte
can be used to represent 2^8 or 256 different values.

CELL-CORE PROCESSOR
• is a microprocessor chip with a multi-core , parallel processing architecture
and floating-point design. The chip, the prototype for which was introduced
early in 2005, is the product of a team of engineers from IBM, Sony Group,
and Toshiba Corporation.

CLOCK SPEED
• Clock speed is the rate at which a processor can complete a processing
cycle. It is typically measured in megahertz or gigahertz. One megahertz is
equal to one million cycles per second, while one gigahertz equals one
billion cycles per second. This means a 1.8 GHz processor has twice the clock
speed of a 900 MHz processor.

DVD
• Stands for "Digital Versatile Disc." It can also stand for "Digital Video Disc,“ it is
a high-capacity optical disc that looks like a CD, but can store much more
information. While a CD can store 650 to 700 MB of data, a single-layer,
single-sided DVD can store 4.7 GB of data.

EMULATOR
• when one system imitates or reproduces another system. This can be done
using hardware, software, or a combination of the two.

FLASH MEMORY
• a type of electrically erasable programmable read-only memory (EEPROM).
a section of memory cells can be erased in a single action or in a "flash." A
common use of flash memory is to store the BIOS settings in a computer's
ROM. When the BIOS needs to be changed, the flash memory can be
written in blocks, rather than bytes, making it easy to update.

GIGABYTE (GB)
• A gigabyte is 109 or 1,000,000,000 bytes
• One gigabyte (abbreviated "GB") is equal to 1,000 megabytes and
precedes the terabyte unit of measurement. Gigabytes, sometimes
abbreviated "gigs," are often used to measure storage capacity.

GIGAHERTZ (GHZ)
• One gigahertz is equal to 1,000 megahertz (MHz) or 1,000,000,000 Hz. It is
commonly used to measure computer processing speeds. For many years,
computer CPU speeds were measured in megahertz, but after personal
computers eclipsed the 1,000 Mhz mark around the year 2000, gigahertz
became the standard measurement unit.
• While gigahertz is most commonly used to measure processor speed, it can
also measure the speed of other parts of the computer, such as the RAM
and backside cache.

HARD DRIVE
• The primary computer storage device, which spins, reads and writes one or
more fixed disk platters. Hard drives are the storage medium in desktop and
laptop computers as well as all servers and mainframes throughout the
world. They are also used in printers for storing fonts and print jobs as well as
the classic iPod and myriad other portable and stationary computer-based
devices.

LCD
• (Liquid Crystal Display) A screen display technology developed in 1963 at
the David Sarnoff Research Center in Princeton, NJ. between polarizing filters
and glass panels, liquid crystals are rod-shaped molecules that flow like liquid
and bend light like crystal. The orientation of the filters and panels
determines how light passes through the crystals.

MEGABYTE (MB)
• 1. A unit of computer memory or data storage capacity equal to 1,048,576
(220) bytes. 1 megabyte is equal to 1,000,000 bytes
• Megabytes are often used to measure the size of large files. For example, a
high resolution JPEG image file might range is size from one to five
megabytes

MEGAHERTZ (MHZ)
• Megahertz is used to measure wave frequencies, as well as the speed of
microprocessors. Radio waves, which are used for both radio and TV
broadcasts, are typically measured in megahertz.
• Megahertz is also used to measure processor clock speeds. This
measurement indicates how many instruction cycles per second a processor
can perform. While the clock speeds of processors in mobile devices and
other small electronics are still measured in megahertz, modern computer
processors are typically measured in gigahertz.

ODD (OPTICAL DISK DRIVE)
• Optical drives retrieve and/or store data on optical discs like CDs, DVDs, and
BDs (Blu-ray discs) which hold much more information than classic portable
media options like the floppy disk.

PIXEL SHADING
• The name used to describe the method in which a GPU applies textures and
renders pixels to the display. Pixel Shaders are used to give a more realistic
look to objects, such as reflections.

RAM
• Stands for "Random Access Memory," Every time you open a program, it gets
loaded from the hard drive into the RAM. This is because reading data from
the RAM is much faster than reading data from the hard drive. Running
programs from the RAM of the computer allows them to function without
any lag time. The more RAM your computer has, the more data can be
loaded from the hard drive into the RAM, which can effectively speed up
your computer.

ROM
• Stands for "Read-Only Memory." ROM is memory containing hardwired
instructions that the computer uses when it boots up, before the system
software loads. In PCs, the instructions are read from a small program in the
ROM, called the BIOS (Basic Input/Output System).

TRIPLE-CORE PROCESSOR
• A single chip with three distinct processors that work simultaneously. For
example, AMD introduced its triple-core Phenom Tri-Core X3 8000 series in
2008
• These cores are units that read and execute different program instructions.
The program instructions are regular CPU instructions, including add, branch,
and move data; however, the availability of three different cores in a single
unit helps to execute multiple instructions simultaneously, which greatly
improves overall program speed.

VERTEX SHADING
• A programmable function in display adapters that offers a graphics
application programmer flexibility in rendering an image. The vertex shader is
used to transform the attributes of vertices (points of a triangle) such as color,
texture, position and direction from the original color space to the display
space. It allows the original objects to be distorted or reshaped in any manner.
