what is a USB drive?
A USB is also known as a USB flash drive or a keychain drive it is a storage device that uses flash memory and is lightweight enough to attach to a key chain. A USB drive can be used in place of a floppy disk, Zip drive or a CD. When the user plugs the device into USB port, the computers operating system recognizes the device as a removable drive and assigns it a drive letter.

A hard disk drive is also known as a disk drive that stores and provides relatively quick access to large amounts of data. Most computers typically come with a hard disk that contains several bytes of storage.
a hard disk is set of stacked disks.What is a LCD monitor
A LCD monitor is a thin, flat electronic visual display, Light modulating properties of liquid crystals form a array of pixels.
The brightness of an LCD is made to be brighter by increasing the brightness of the backlight. In case of a CRT, a increasing brightness also increases the beam spot size.
CRT monitors
In a CRT monitor the image quality is Excellent, there is no pixelation . The black levels are good out performing digitals by a minimum or 10:1
The CRT monitors a large and heavy. The tubes are expensive to replace when they wear out.
They are also not as bright as some current LCD or DLP models.

Performs the instructions of a computers programs. The CPU performs arithmetical logical operations on data held in computer memory(the RAM). The RAM is seen as a vector that contains instructions and data provided by the computer programmer.
RAM
A ram stands for Random access memory and is used for computer data storage. A RAM allows stored data to be accessed in nearly the same amount of time for any storage location.
there is two different types of RAM there's DRAM and SRAM DRAM stands for Dynamic random access memory and SRAM stands for Static random access memory.

Inputs and Outputs
Inputs to a computer are keyboard or mouse.
Touch Screens
A type of display screen that has a touch-sensitive transparent panel covering the screen.
MOTHERBOARD
A motherboard is a main circuit board of a microcomputer. A motherboard contains CPU, BIOS, memory, mass storage interfaces, serial and parallel ports. On most computers it is possible to add memory chips directly to the motherboard.
Inputs and Outputs
Inputs to a computer are keyboard or mouse. as well as touch screen, drawing pens, and touchpads. An output would be a computer screen, printer, or computerized machinery that receives information to make a product better
Touch screens
A type of display screen that has a touch-sensitive transparent panel covering the screen. Instead of using a pointing device such as a mouse or light pen, you can use your finger to point directly to objects on the screen.
