Transcription de la présentation

  1. Computer Literacy Presentation Eric Spittler and Andreina Guedez

  2. Basic concepts FOR COMPUTER NETWORK Protocol: rules and conventions for communication between network devices. Channel: physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel. Device Driver: is a computer program that operates or controls a particular type of device that is attached to a computer

  3. Data Bus A data bus is a computer subsystem that allows for the transferring of data from one component to another on a motherboard or system board, or between two computers.

  4. Controller/Expansion Card An expansion card is an electronic circuit board that adds more functionality to a desktop computer. Expansion cards are installed into the expansion slot of a computer motherboard. They enhance the computer’s ability to perform additional functions not offered by the motherboard.

  5. FireWire Firewire is an alternative type of port (connection) on your computer, for connecting devices. Firewire's biggest advantage over USB is not speed though, its the fact that Firewire is an intelligent peer to peer connection. As long as the devices supported it, you could theoretically hook a videocamera to a stand-alone DVD burner if they both had Firewire

  6. Network A network, is a collection of computers and other hardware interconnected by communication channels that allow sharing of resources and information.

  7. Lan vs. wan vs. wlan vs. pan WLAN: Wireless Local Area Network (computers in your house networked together without a cable) LAN: Local Area Network (computers in your house networked together) PAN: Personal Area Network when a network is established by connecting phone lines to personal digital devices or PDAs (personal digital assistants), WAN: Wide area Network (connection to your ISP)

  8. Infrared technology vs. Bluetooth distance an infrared signal can travel varies based on the strength of the remote, but is usually less than 50 feet for household electronics Use radio frequency, which allows transmission through walls and other objects In order for an infrared signal to be detected, there must be a direct line of sight between the transmitter (remote) and the receiver (TV) The standard range of a Class 3 Bluetooth device is about 30 ft

  9. What 512K Connection Means? 1 megabit = 1024 kilobits

  10. Differences between Dial up, DSL, Satellite and Cable Modem
