  1. THE DIFFERENT TYPES OF DEVICESOguzhan Turgul, 12B1

  2. INPUT DEVICES • Mouse - The mouse is used to open and close files, navigate web sites, and click on a lot of commands (to tell the computer what to do) when using different applications. • Keyboard - The keyboard is a way to input letters or numbers into different applications or programs.  A keyboard also has special keys that help operate the computer. • Camera - Most cameras are used during live conversations.  The camera transmits a picture from one to another, or can be used to record a short video.

  3. OUTPUT DEVICES • Monitor - A monitor is the screen on which words, numbers, and graphics can be seem.  The monitor is the most common output device. Printer- A printer prints whatever is on the monitor onto paper.  Printers can print words, numbers, or pictures. Speaker - A speaker gives you sound output from your computer.  Some speakers are built into the computer and some are separate.

  4. Storage Devices • Random Access Memory- A type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. • Hard Disc Drive- The hard disk drive is the main, and usually largest, data storage device in a computer. The operating system, software titles and most other files are stored in the hard disk drive. • Optical Disc 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.

  5. Communication Devices • Modem-A modem is an example of an interface. • The purpose of a modem is to convert between the analogue signals used in telephone cables and the digital signals used by a computer. • Digital phone lines- It is not necessary to use a modem when using a digital telephone line such as an ISDN (Integrated Services Digital Network)line to connect a computer (or a LAN) to the internet because the signal is already a digital one which a computer can process.
