PRINTER:
A computer printer is another type of output device. Many modern printers have the ability to interface with different media types such as memory sticks, memory cards, and cameras. You will also see what are called multi-function printers that combine printing, scanning, faxing, and photocopying all into one device.
MONITOR:
The monitor is your view into the computer. They come in all shapes and sizes, but the main ones being sold today are LCD (Liquid Crystal Display) monitors. There's quite a big difference between LCD and CRT (Cathode Ray Tube) monitors and CRT monitors are slowly being phased out and replaced by LCD's. LCD monitors are much lighter and thinner, they take up less space, and provide a crisper more focused image.
Computer speakers, or multimedia speakers, are speakers external to a computer, that disable the lower fidelity built-in speaker. They often have a low-power internal amplifier.
In computing, an image scanner—often abbreviated to just scanner— is a device that optically scans images, printed text,handwriting, or an object, and converts it to a digital image.
The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions. The central processing unit carries out each instruction of the program in sequence, to perform the basic arithmetical, logical, and input/output operations of the system.
