In this blog it will be about the hardware components which will be needed to set up a home office.
There are several hardware components that you will need to make a home office:
- Monitor – The most comon output device is the monitor. Monitors has changed over the period of time from 4:3 to 16:9 or maybe 16:10. There are amny types of differnet brands for example LCD, Plasma, LG. Modern monitors are mostly Liquid Crtstal Displays (LCD), Thin Film Transistors (TFT) monitors. The older monitors are Cathod Ray Tube (CRT) monitors.
- Keyboards – The most common input is a keyboard. A keyboard has loads of buttons and keys, it is just like a old fashion typewriter. There are 3 main keyboards: a standard, a laptop size and a thumb size. Desktop computer keyboards, such as the 101 key US traditional keyboards or the 104 Windows keyboards, include alphabetic letters, numbers, symbols, and a variety of function keys. A laptop size keyboard usually have shorter travel distance for the key strokes and a reduced set of keys.
- Mouse – Another most common input device is a mouse. A mouse is a pointing device that functions by detecting two dimensional motion relativeto it’s supporting surface. The earlier mice is the Trackball, which is invented by Tom Cranston. The Trackball is used at alternative to a mouse. User’s operate it by rotating the ball which moved the pointer on the screen. The Trackball are often used in the Computer Aided Design (CAD).
- Microphone – Microphones are used to input sound. In computing they can be used with voice recognation software and a word processing application to enter text. Web cams often have a mircophone in them. Most microphonnes are used in many applications such as: telephones, tape recoders, karaoke systemm etc. There are many microphones invented here are some examples: Condenser Microphone, Dymanic Microphones, Carbon Microphones.
- Scanner – A scanner can be used to digitise images. They are similar to a photocopier but they make a digital copy instead of a physical copy. Scanners can also be used with optical character recognation (OCR) software to scan text that is editable. The modern scanners are typically used a charge-coupled device (CCD) or a Contact Image Senser (CIS) whereas older drum scanners use a photomultiplier tube as the image sensor. A rotary scanner is used for high speed document scanning it is another type of drum scanner but using a CCD array instead of a photomultilier. There are moire types of scanner for example planetary scanner, these type of scanners take photographs of books and documents and there are also 3D scanners, these type of scanners as used to produce 3 dimensional models of objects.
