WAN – (wide area network): The computers are in different geographic locations and are connected by telephone lines or radio waves.
NWay Protocol A network protocol that can automatically negotiate the highest possible transmission speed between two devices.
P
PING | Packet Internet Groper, a utility used to determine whether a |
| specific IP address is accessible. It functions by sending a packet |
| to the specified address and waits for a reply. It is primarily used |
| to troubleshoot Internet connections. |
PPPoE | |
| connecting the users on an Ethernet to the Internet through a |
| common broadband medium, such as DSL or cable modem. All |
| the users over the Ethernet share a common connection. |
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 token- |
| passing and Carrier Sense Multiple Access with Collision |
| Detection (CSMA/CD),implemented as |
| 106 |
| FDDI, or Ethernet. The Router Information 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, |
| stations, |
Subnet mask | In TCP/IP, the bits used to create the subnet are called the subnet |
| mask. |
