Ø 32-bit/16-bit:
There are many advantages that 32 bit has over the 16 bit applications. 32 bit application have their own address space which creates a stable environment for a computer system. Whereas the 16 bit version runs in a shared address space which means if you experience a 16 bit application crash, it can crash the entire system. In addition, 32 bit runs much faster, it can handle multitasking and can handle much longer filenames than can the 16 bit application.

Ø AI:
Stands for Artificial Intelligence. This is the area of computer science focusing on creating machines that can engage on behaviors that humans consider intelligent. The ability to create intelligent machines has intrigued humans since ancient times, and today with the advent of the computer and 50 years of research into AI programming techniques, the dream of smart machines is becoming a reality. Researchers are creating systems which can mimic human thought, understand speech, beat the best human chess player, and countless other feats never before possible.

Ø Alert Box
The little box that pops up to inform you that the computer you are working on is about to perform an operation which may have damaging consequences is called the alert box. In a way, the alert box is certainly a help, especially when you might have typed in a command absentmindedly and would not like to go through with it! Most of the time you can make it go away by a click of the buttons available or by using the mouse.

Apache is the most popular Web server software. It enables a
computer to host one or more websites that can be accessed over the Internet
using a Web browser. The first version of Apache was released in 1995 by the
Apache Group. In 1999, the Apache Group became the Apache Software Foundation,
a non-profit organization that currently maintains the development of the Apache
Web server software.
Apache's popularity in the Web hosting market is largely because
it is open source and free to use. Therefore, Web hosting companies can offer
Apache-based Web hosting solutions at minimal costs. Other server software,
such as Windows Server, requires a commercial license. Apache also supports
multiple platforms, including Linux, Windows, and Macintosh operating systems.
Since many Linux distributions are also open-source, the Linux/Apache
combination has become the most popular Web hosting configuration.
Apache can host static websites, as well as dynamic websites that
use server-side scripting languages, such as PHP, Python, or Perl. Support for
these and other languages is implemented through modules, or installation
packages that are added to the standard Apache installation. Apache also
supports other modules, which offer advanced security options, file management
tools, and other features.
Most Apache installations include a URL rewriting module called
"mod_rewrite," which has become a common way for webmasters to create
custom URLs.
While the Apache Web server software is commonly referred to as
just "Apache," it is technically called "Apache HTTP
Server," since the software serves webpages over the HTTP protocol. When
Apache is running, its process name is "httpd," which is short for
"HTTP daemon."
Ø AppleTalk:
A protocol suite developed by Apple Computer in the early 1980s, was developed in conjunction with the Macintosh computer. AppleTalk's purpose was to allow multiple users to share resources, such as files and printers. The devices that supply these resources are called servers, while the devices that make use of these resources (such as a user's Macintosh computer) are referred to as clients. Hence, AppleTalk is one of the early implementations of a distributed client/server networking system.
Ø AppleScript:
It is a kind of English-like language that is used to write specific script files which have the ability to automate the actions of the computer systems and applications that run on it.

Ø ARP:
Stands for "Address Resolution Protocol." ARP is a
protocol used for mapping an IP address to a computer connected to a local
network LAN. Since each computer has a unique physical address called a MAC
address, the ARP converts the IP address to the MAC address. This ensures each
computer has a unique network identification.
The Address Resolution Protocol is used when information sent to a
network arrives at the gateway, which serves as the entrance point to the
network. The gateway uses the ARP to locate the MAC address of the computer
based on the IP address the data is being sent to. The ARP typically looks up
this information in a table called the "ARP cache." If the address is
found, the information is relayed to the gateway, which will send the incoming
data to the appropriate machine. It may also convert the data to the correct
network format if necessary.
If the address is not found, the ARP broadcasts a "request
packet" to other machines on the network to see if the IP address belongs
to a machine not listed in the ARP cache. If a valid system is located, the
information will be relayed to the gateway and the ARP cache will be updated
with the new information. By updating the ARP cache, future requests for that
IP address will be much quicker. While this may seem like a complex process, it
usually takes only a fraction of a second to complete. If only it was just as
easy to find old receipts when you need them.
Ø ASCII:
It stands for "American Standard Code Information Exchange" and is pronounced (ask-ee). A standard code or protocol for displaying characters and transferring data between computers and associated equipment. It was developed for the purpose of information exchange among the following:
-Associated equipment
-Data communications systems
-Data processing systems

Ø Asynchronous:
1 : not synchronous; not occurring or existing at the same time or having the same period or phase.
2 : of, used in, or being digital communication (as between computers) in which there is no timing requirement for transmission and in which the start of each character is individually signaled by the transmitting device.
