FTP (File transfer protocol): Used to exchange files over the Internet.
SMTP (Simple Mail Transfer Protocol): An Internet protocol used to provide electronic mail services.
DNS (Domain name server): An Internet service that translates domain names into IP addresses .
DHCP (Dynamic Host Configuration Protocol): A protocol for assigning dynamic IP addresses to devices on a network.
Gateway : A device on a network that serves as an entrance to another network. A gateway on a LAN is typically the address of the router. This can be found in Windows by typing “ipconfig” into a command prompt. A sample IP would look as follows: 192.168.0.1
Hostname : The name of the computer on the network. This can be found by typing “ipconfig /all” in the command prompt.
IP (Internet Protocol) address : A number that uniquely identifies every host on a network. This can be found by typing “ipconfig” into a command prompt. An example of a LAN IP would be 192.168.0.11, and an example of a WAN IP would be 18.104.22.168
Dynamic IP address : An IP that changes each time the computer connects to the network. Usually used on a dial-up connection.
Static IP address : An IP that stays the same each time the computer connects to the network. Normally used on a high speed or broadband connection.
Physical address : An address associated with a particular network device. This is also known as a MAC address and can be retrieved by typing “ipconfig /all” into a command prompt in the Windows Operating System.
Subnet mask : A 32-bit address mask used in IP to specify a particular subnet. This can be retrieved by typing “ipconfig /all” into a Windows command prompt.
To retrieve any of these items in a Linux operating system substitute the “ipconfig” command with the “ifconfig” command in the terminal.
Fiber Optic Cable:
LAN (Local–Area Network) : A computer network that spans a small area. Most LANs are confined to a single building or a small group of buildings.
Ethernet : A LAN architecture that supports data transfer rates of 10Mps up to 1Gps. This architecture uses Cat5 cabling to get its desired speeds.
WAN (Wide-Area Network): A computer network that spans a geographical area. Typically a WAN consists of many LANs.
Broadband Internet : A high speed, high capacity, transmission medium carried on coaxial, Cat5 or Fiber-optic cables with a wider bandwidth than conventional telephone lines.
Dial-up Internet : A connection that uses the public switched telephone network rather than a dedicated circuit. The connection is established using the phone line, the Internet service provider’s software, a user name and password, and an authentication process done by the Internet service provider.
Bandwidth: The amount of data that can be transmitted in a fixed amount of time, usually expressed in bits per second or bytes per second.
