Answer:
Microcomputer
These ae also known as personal computers (PCs). They are small in sizes and relatively inexpensive. They are highly flexible and designed for small scale personal use and business application. these are based on microprocessor technology, a silicon chip containing the important circuitry to perform operations. IBM, Dell, Sony, HP and Apple are the manufactures of microcomputers. Nowadays they have come more advance and powerful in technology.
The business community uses personal computer for word processing, desktop publication, inventory and accounting software like QuickBooks and spreadsheets. At home users perform surfing internet and playing games.
Minicomputer
Compare to mainframe these are midrange computers, small in size and more compact and less expensive. They are designed for computerization of data, scientific research, industrial process, data collection and telephone switches. Minicomputers are multiprocessing system and can support upto 200 user at a time but the power of processing is not as great as the mainframe and supercomputers. Timesharing, batch processing and online processing is available on these midrange computers.
Examples of Minicomputers
IBM System/3
Honeywell 200
TI-990
Mainframe Computer
Mainframe computers can store huge amount of data. They are large in size and memory, power and expensive. These machines are capable to different operating system on the same time and support time sharing and virtual memory. Universities, banking institutions, stock exchanges, insurance companies are some examples of using mainframe servers for maintaining students’ data, ATM transactions, financial transactions, clients and employees’ records.
The main difference between supercomputer and mainframes is that supercomputer has a speed of calculations and mostly used for space scientific and engineering related problems i.e. data crunching while mainframe servers are used for transaction process.
Modern mainframes Computers
IBM zSeries
System z9
System z10 servers
Supercomputer
The term “super computer” is considered the most powerful computers in performance and processing. Supercomputers are capable to solve immense mathematical calculations, scientific problems and hence it is called number crunchers. They are difficult to design and need teamwork research and development.
speed
super computer are the fatest computer followed by main frame computer then mini computer and microcomputer.
