Why is it that the user terminals of the mainframe computer also called dumb terminals?

they are typically only capable of transferring characters to and from the computer and positioning the cursor as requested by the computer. some have additional capability, depending on the model of the terminal, but they are not capable of independent computations or data storage.

What is the difference between a mini computer and main frame computer?
a main frame computer is a large-scale computers but a super computer are larger than mainframe while a mini computer is smaller in size, have lower processing speed and also have lower cost than mainframe computers.
What are the four classification of computers?
MAINFRAME COMPUTERMINI-COMPUTERMICRO-COMPUTERSUPER-COMPUTERThere are many computers which are different from each other in various aspects. Classification of computers are given below.(1) Micro computers: These computers use a microprocessor chip and this chip is used instead of CPU means that this microprocessor chip works as a CPU.These computers are also called personal computers. Two major types of these computers are laptop or Desktop computers. Only one user uses these computers at time that's why they are also known as personal computers.(2) Mini Computers: These are powerful computer. These computers come into existence in 1960s at that time mainframe computer was very costly. Mini computers were available in cheap prices, so users start using it.(3) Mainframe Computer: It as a very powerful and large computer. You can get idea of its power as it can handle processing of many users at a time.Terminals are used to connect a user to this computer and users submit there task through mainframe. Terminal is a device which has keyboard and a screen. By using terminal users put inputs into the computer and get the output through screen.(4) Super Computers: As the name "super computer" specifies that these are most powerful computers even than mainframe. Actually, when we optimize a mainframe computer then we get super computer.(5) Microprocessor: You will find these computers everywhere. Microprocessor chips are used in many devices as I-pod, DVD, headphone etc.
Who invented the first computer screen?
Until the early 1980's most monitors were terminals. They were boxy video display terminals (VDT's) combined with an attached keyboard.In 1981, IBM introduced the first PC, also known as a "three-piece computer" because the monitor, keyboard and CPU were separate, rather than earlier computer terminals, which combined the monitor and keyboard.

Micro-computer mainframe computer super computer?
micro computer is also known as personal computer... this type of computer available in our home...mainframe computer is very large storage computer. they can store very large amount of data.super computer is used in weather forecasting, in research fields, seismic modeling, nuclear weapon design, aircraft design, etc. super computer can do calculations at least 10 times faster than fastest available regular computer........... this is typically very costly....... yesterday's supercomputer is often out performed by today's computer and therefore new super computers must be designed and built that are at least 10 times faster than today's computer.........super micro computers are the super computers of the micro computers. though often used by the same users that use super computers, their main users are game players. their realistic 3D rendered action games require far more processing power than an ordinary micro computer has, but they could never afford a mainframe or super computer nor could they fit one in their house. high end dedicated game consoles usually contain a dedicated super micro computer!
What is the difference between a workstation and a mainframe?
A network is a group of interconnected communicating devices (computers, portable devices, routers, modems, printers etc.) While a mainframe is a centralized server which provides primary services to a network or multiple networks. Typically, the term 'mainframe' is differentiated between 'server' by way that a mainframe provides service to dummy or smart terminals. Terminals do little or nothing by themselves, and require an established link to the mainframe to boot or function basically. A dummy terminal has no processing capability and boots off the mainframe over the network. IE, it's little more than a network card, monitor, and keyboard. Most ATMs and credit-card machines are dummy terminals- If the mainframe goes down, they become inoperable. A smart terminal, which is more common, has it's own processing capabilities. A desktop computer is an example of a smart terminal, as it can function even if offline. Also, typically, smart terminals will load data from the mainframe then store it on the terminal itself, rather than running entirely from the mainframe.

What does a personal computer stand for?
I refer all those machine (Computer) which is use by the user for personal or commercial purpose. Basically at home or in small organization the machine is on table is a Personal Computer.
Why you use many processors in a mainframe computers?
Mainframe computers are used for bigger and complex environment than mini computer, so many processors are used to increase the efficiency of data processing. It also provides another benifit i.e. a mainframe computer is able to continue to be in service with remaining processors in case one processor is failed.

What happens when you connect the car positive and negative battery terminals together Will this reset car computers?
If you connect the terminals together with them unhooked from the battery and the engine off, yes that is also called a capacitive discharge.If you connect the terminals together with them unhooked from the battery and the engine off, yes that is also called a capacitive discharge.

What is CA11?
I believe it is a mainframe scheduling software related to CA7 It´s a Computer Associates tool that helps to restart jobs in Mainframe. Normally used with CA7 (Schedule tool), but also used with other CA tools (like Jobtrac).
What are the names of old style computer terminal fonts?
In the good old days of computers printing was done on large printers attached to a mainframe computer. The IBM 1403 printer, for example, had a chain (several could be chosen from) each of which had a different font. One was called Chain A and by implication this was also the font name.
What are the different between mainframe and PC?
Typically mainframes run hundreds of terminals. PCs tend to be stand alone devices. In the old days mainframe computers were the size of refrigerators or larger. Today, however, you can achieve the equivalent in mainframe processing power by linking a series of PCs together with gigabit network interface cards, so the distinction gets a little blurry. In addition, mainframes do not have to act as big terminal servers to qualify as mainframes. Although mainframes are usually found in banks, large corporations, and universities, where they run hundreds of terminals, they are also used by scientists for massive modeling computations and in the scientific analysis of very large volumes of data.
What kind of companies make up the computer terminal industry?
Companies primarily engaged in manufacturing computer terminals, teleprinters, and multistation cathode ray tubes (CRTs) make up the computer terminal industry.
What are the example of mainframe computing?
IBM system 3 and AS-400 are some examples of minicomputers.
