Ping | Packet Internet Groper is a utility used to determine whether a |
| particular network device (IP address) is available online. It works by |
| sending out a packet to the device and waiting for its response. |
PPPoE | |
| encapsulation of PPP packets over Ethernet frames. |
PPTP | PPTP stands for |
| allows authorized users to extend their own networks through private |
| “tunnels” over the ISP or online service. This kind of interconnection is |
| known as VPN ( Virtual Private Network) |
A connector used for Ethernet devices that holds up to eight wires. | |
Router | A router is a device that interconnects networks. |
Subnet Mask | Subnet masking is a method of splitting IP networks into subgroups. |
TCP | Transmission Control Protocol enables two hosts to establish a |
| connection and exchange streams of data, guaranteeing delivery of |
| data and that packets will be delivered in the same order in which |
| they were sent. |
Throughput | It is the measurable amount of data moved from one place to |
| another within a given time period. |
UDP | User Datagram Protocol is a connectionless protocol that, like TCP, |
| runs on top of IP networks. Unlike TCP/IP, UDP provides a direct way to |
| send and receive datagrams over an IP network and is used primarily |
| for broadcasting messages over a network. |
URL | Uniform Resource Locator is the address that defines the location of a |
| file on the World Wide Web. |
UTP | Unshielded Twisted Pair is the most common kind of copper wiring |
| designed to reduce crosstalk between copper wires. |
VPN | Virtual Private Network is a secure means to join remote networks |
| using comprehensive authentication and encryption. They may be |
| “virtually” joined even across a public network like the Internet by |
| means of employing IPSec amongst others. |
WAN | Wide Area Network. It is a communication network that extends over |
| a large geographical area. For example, the Internet. |
WEP | Wired Equivalent Privacy is a wireless data privacy encryption |
| protocol based on a |
WLAN | Wireless Local Area Network is a group of computers and associated |
| devices that communicate with each other wirelessly. |
| |
| server and yet provides the same strong encryption protection. |
