  Term Name Description

Network

A group of computers which are connected together through hardware and software.

WinSock

Windows Sockets. An API for sockets through windows, which provides TCP/IP network programming support.

SPX

Sequenced Packet Exchange. A reliable network protocol introduced by Novell Netware. Complimentary protocol would be IPX.

IPX

Internetwork Packet Exchange. An unreliable (datagram) protocol introduced by Novell Netware. Complimentary protocol would be SPX.

LAN

Local Area Network. A computer network limited to the immediate area, often connected with Ethernet. It is often supported in multiplayer games.

Lag

The time it takes information to go from one computer to another. Usually it is only refered to when it is noticeably slow. See latency.

Latency

The time it takes for information to travel. Often measured in the time information can go across a network and return with the "ping" command. Sometimes called lag.

Uploading

The process of transfering information from a client to a host. Ex: When you send a file from your computer to an FTP site.

Download

The process of transfering information from a host source to a client. Ex: When you surf the web you are downloading information from web sites.

BPS

Bits Per Second. A measurement of speed for transfering information.

Bandwidth

Refers to a measurement of how many bits can be transfered over a path at once. For instance a pipe may be able to send 16 bits at once which would be called 16 bits of bandwidth.

Client / Server

An architecture in which there is a main source of information, the server, and it is accesed when the information is needed by the clients.

ADSL

Asymmetric Digital Subscriber Line. As opposed to SDSL (Symmetric Digital Subscriber Line), an ADSL connection runs through an ordinary phone line and receives data over the internet at high speeds, comparable to those of cable modems, though it transmits data at only a fraction of the speed at which it receives data -- but still faster than a conventional 56Kbps modem.

UDP

User Datagram Protocol. An unreliable method of sending packets, UDP is faster but less stable in terms of reliable information than TCP. UDP is often used for faster transmission of data that is not useful at a later time.

TCP

Transmission Control Protocol, is used for reliable packet transfer. Packets are slower in nature as they are always checked and will arrive to the applications in the proper order.

TCP/IP

A suite of protocols that is the standard on the Internet. There are 13 protocols overall, including telnet, FTP, TCP, UDP and RDP. See TCP and UDP.
