What are the 3 major classifications of computers?

Answer 1

There are only 2 kinds of people in the world, those who divide people into 2 categories, and those who don't.

You can classify computers in almost as many ways as you can classify computers. Some examples:

1. mechanical (abacus, slide rule)
2. analog electronic (rarely used nowadays)
3. digital electronic
4. biological (the brain)

or
1. scientific (emphasizing floating point)
2. commercial (emphasizing fixed point)

or by the kind and degree of parallelism
1. single
2. pipelined
3. threaded
4. multiprocessor (especially shared memory)
5. massively parallel

or by the kind of application
1. embedded (in your watch, oven, cell phone, car)
2. mobile (in your PDA)
3. portable (your laptop)
4. desktop (personal workstation)
5. server (file, web, network, compute)
6. mainframe
7. supercomputer

Classifications Of Computer

Answer 4

Who is the "we" and how does one "do away" with any human conceptualization? In these days of Political Correctness, some might argue that there is no need for the differentiation of humans by what is called Race. There are probably more that are fighting tooth and nail to keep the concept alive. It is not always a matter of taxonomic rigor and validity. Similar to Gender differentiation, the concept of Race for crude physical phenotypes is highly useful for the medical profession. It is not because of the strange mixture of genetic material in some humans that changes the concept of Race for peoples who are mostly of one genetic background. Yes, Race is a social construct. It always has been. It has lead to many adverse interactions of people in the past, but an attempt to eliminate the concept may have no valid point. Those who are the strongest supporters of the concept learned it at home and not in any school system. Nothing will change by eliminating the word Race from educational materials. The best that humanity can hope for is to pass on to our children the concept of Humanity as a whole and to not judge any individual by the way he or she looks.

Answer 5

I'm going to assume that you're referring to classical theoretical computer science. If so, broadly speaking (there are lots of variations here), they are:

1. Finite State Automaton (basically a state transition machine)
2. Push-Down Automaton (think of a state transition machine with a push-down stack like an old HP calculator)
3. Turing Machine (think of a state transition machine with a infinite supply of tape which can be read from and written to)

Each of these 'machines' accepts a certain kind of program ('grammar') and each one is 'more powerful' (can do more complex operations, has memory) than the previous one on the list.

I can't begin to get into the specific of this stuff, as they teach whole graduate seminars on it and it gets rather esoteric (lots of Greek symbols and abstraction).

These machines correspond to something called the Chomsky (after Naom Chomsky) hierarchy of automata, where each type of machine accepts a grammar. If my memory is working well, I think it goes...

FSAs accept regular grammars
PDAs accept context-sensitive grammars
TMs accept context-free grammars

Answer 6

Well it depends, what the classification is regarding. But are you sure there are 3 classifications?

Typically there are 4 types of computers:
* Mainframe Computers
* Minicomputers
* Microcomputers
* Supercomputers

Or according to their architecture:
•SISD (Single Instruction Stream, Single Data Stream)
•SIMD (Single Instruction Stream, Multiple Data Stream)
•MISD (Multiple Instruction Stream, Single Data Stream)
•MIMD (Multiple Instruction Stream, Multiple Data Stream)
(see Flynn's taxonomy)

Answer 7

kis_kat, you are too good. Actually, as a sometimes software developer, I formally learned the first three items in your list were widely recognized as the so-called three major types of computers. But duh, there were just so few super-computers—relatively speaking—that I guess the books just omitted them for convenience sake. Go figure!

Ben and paulmaxpayton... Well done.

I guess we do need to know from what perspective the questionnner is coming from: application, commercial, or technical.
