e-mail, file transfers, and other network services.
The service is used by a client, program, a computer
or another system. The server and client do not necessarily
need to be on the same computer.
What is a platform? A
platform is any base of technologies on which other
technologies or processes are built. It is also an underlying
computer system on which application programs can run.
On personal computers, Windows 95 and the Macintosh
are examples of two different platforms. On enterprise
servers or mainframes, IBM's System/390 is an example
of a platform.
A platform consists of an operating
system, the computer system's coordinating program,
and a microprocessor, the microchip in the computer
that performs logic operations and manages data movement
in the computer. The operating system must be designed
to work with the particular microprocessor's set of
instructions. As an example, Microsoft's Windows 95
is built to work with a series of microprocessors from
the Intel Corporation that share the same or similar
sets of instructions. There are usually other implied
parts in any computer platform such as a motherboard
and a data bus, but these parts have increasingly become
modularized and standardized.
What does it mean when someone
says "a client for a particular platform"?
It means that the client program is designed to work
with one or more specific platforms and each platform
requires a specific kind of client.

and therefore academic research can be problematic.
There have also been security problems where people
have been duped out of money. However, there are certain
measures one can take when working on the Internet such
as thoroughly checking Internet resources and ensuring
some sort of reliable identification and encryption
system when disclosing personal and financial information.

find information about subjects that they are studying.

Why is culture an important
consideration when communicating interculturally?

the desired message getting across.
