Protocol | Communication on the network is governed by sets of rules |
| called protocols. Protocols provide the guidelines devices use to |
| communicate with each other, and thus they have different functions. |
| Some protocols are responsible for formatting and presenting and |
| presenting data that will be transferred from file server memory |
| to the file server’s net work adapter Others are responsible for |
| filtering information between networks and forwarding data to its |
| destination. Still other protocols dictate how data is transferred |
| across the medium, and how servers respond to workstation requests |
| and vice versa. Common network protocols responsible for the |
| presentation and formatting of data for a network operating system |
| are the Internetwork Packet Exchange (IPX) protocol or the Internet |
| Protocol (IP). Protocols that dictate the format of data for transferors |
| the medium include |
| Access with Collision Detection (CSMA/CD),implemented as |
| |
| Protocol (RIP),a part of the Transmission Control Protocol/Internet |
| Protocol (TCP/IP) suite, forwards packets from one network to |
| another using the same network protocol. |
R
RARP | Reverse Address Resolution Protocol, a TCP/IP protocol that allows |
| a physical address, such as an Ethernet address, to be translated into |
| an IP address. |
Router | A router is the network software or hardware entity charged |
| with routing packets between networks. |
S
Server | It is a simple computer that provides resources, such as files or other |
| information. |
SMTP | The Simple Mail Transfer Protocol is used for Internet mail. |
SNMP | Simple Network Management Protocol. SNMP was designed to |
| provide a common foundation for managing network devices. |
Station | In LANs, a station consists of a device that can communicate data |
| on the network. In FDDI, a station includes both physical nodes and |
| addressable logical devices. Workstations, |
| |
Subnet mask | In TCP/IP, the bits used to create the subnet are called the subnet |
| mask. |
