Hybrid Computers
Classification of Computers based on capacity
Microcomputers
Minicomputers
Mainframes
Supercomputer
have the ability to store different programs of instruction and thus, perform a variety of operations
general purpose
designed to perform one specific task. The program of instructions is built into, or permanently stored in the machine.
special purpose
used for scientific, engineering, and process control purposes. They deal with quantities that are continuously variable.
analog computers
The name analog comes from the word “___-” meaning similar.
analogous
machines that specialize in counting. It operates by counting values that are discrete, or separate and distinct.
digital computer
combines the measuring capabilities of the analog computer and the logical and control capabilities of the digital computer. It offers an efficient and economical method of working out special types of problems in science and various areas of engineering
hybrid computers
arguably the most powerful in terms of speed and accuracy.
used in solving complex mathematical computations.
capable of executing trillions of instructions per second, calculated in floating point operations per second (FLOPS).
supercomputer
are large-sized computer types. They are equally powerful but fall short in terms of the computation ability in supercomputers
mainframe computers
general-purpose devices without the monumental expenses associated with a larger system. Their processing power is below that of mainframe systems but above the capabilities of personal computers
minicomputers
minicomputers are also known as
mid-range computers
smallest, least expensive, and most used , have small memories, less processing power, are physically smaller, and permit fewer peripherals.
microcomputers/personal computers or simply PC
