The protocol, or set of rules, that performs the addressing function of the 
Internet. Every packet of data traveling over Internet networks includes an IP 
address of its destination and of its sender. Routers and other devices to direct 
Internet traffic to its proper destination use this IP address. 

One thousand cycles per second; a unit of measure for frequency. 

A computer network technology designed to connect computers separated by 
a short distance. The local group of linked computers is generally connected to 
a single, shared server. 

One million cycles per second; a unit of measure for frequency. 

A device that you connect to your computer and to a phone line, that allows 
the computer to talk to other computers through the phone system. Basically, 
PC cards do for computers what a telephone does for humans. 

The software controlling the overall operation of a multipurpose computer 
system, including such tasks as memory allocation, input, and output 
distribution, interrupt processing, and job scheduling. 

A feature that is an advanced performance accelerator for TCP/IP-based 
wireless applications such as e-mail, vertical enterprise applications, and Web 
browsing. The AT&T Wireless Communication Manager Optimization feature 
offers unique compression, acceleration and content adaptation techniques to 
dramatically improve bandwidth utilization for wireless data applications. It 
allows the user to retain total “on-the-fly” control of the type and quality of 
content they receive. It also provides performance improvement over native 
wireless services that increases productivity, decreases airtime/per packet 
charges, and enables three times the number of users on the wireless data 
infrastructure. 

A set of rules or standards that enable computers to connect with each other 
to exchange information. 

The PC’s primary storage area, used to write, store and retrieve information 
and program instructions, which are then passed to the CPU for processing. 
The type of RAM used affects performance, as the information stored here has 
to be refreshed many times per second by the processor. Manufacturers are 
continually coming up with new designs to provide the fastest possible access 
times at the lowest possible cost. 

An integrated circuit chip containing programs and data that can be accessed 
and read but cannot be modified. 

The communications protocol used by UNIX systems and the Internet. TCP 
checks for lost packets, puts the data from multiple packets into the correct 
order and requests that missing or damaged packets be resent.
