List three computer system types and specify how they differ from eachother.?

Question

What kind of business situation in which each one would be used?

Answer 1

There are more than three on the website below but I've listed three for you here. Check the link though. It gives a pretty good description of various systems.

The personal computer (PC) defines a computer designed for general use by a single person. While a Mac is a PC, most people relate the term with systems that run the Windows operating system. PCs were first known as microcomputers because they were a complete computer but built on a smaller scale than the huge systems in use by most businesses.

Palmtop - More commonly known as Personal Digital Assistants (PDAs), palmtops are tightly integrated computers that often use flash memory instead of a hard drive for storage. These computers usually do not have keyboards but rely on touchscreen technology for user input. Palmtops are typically smaller than a paperback novel, very lightweight with a reasonable battery life. A slightly larger and heavier version of the palmtop is the handheld computer.

Server - A computer that has been optimized to provide services to other computers over a network. Servers usually have powerful processors, lots of memory and large hard drives.

Answer 2

I'm not sure what you mean by "computer system types." For this purpose I'm going to assume you mean "operating systems."
The three main OS's are Windows XP or VISTA, Mac OSX, and any of the various flavors of Linux.
Windows is by far the most popular, found in over 90% of all personal computers. It is easy to learn and reasonably stable. There are thousands of add-on programs available for every possible use, both commercial and freeware. The browser that comes with it, Internet Explorer, is versatile and fast. However, it is particularly subject to invasion by hackers, if only because it's so popular that it's worth hacking.
Mac OSX comes with Mac computers, product of the Apple Corporation. Those who use it swear it is almost perfectly reliable. It comes already bundled with just about every utility anyone could want, and now it can run Windows programs, too.
Linux, sometimes called the geeks' operating system, can be balky and difficult to learn. There are many varieties, including Debian, Ubuntu, and Red Hat. Some are commercially sold, but most are free for the taking, as is much of the software associated with it.
All three OS's support every kind of business utility, including word processing, databases, and presentations.
