Even large companies use the minicomputers for completion of the specific task such as production, design etc. Minicomputers cannot process a large amount of data in comparison with the supercomputers.
Some of the popular mini computers are
- Texas Instrument TI-990
- IBM Midrange computers
Laptops, desktops, tablets, personal digital assistants, smart phones, calculators – All these devices will come under the category of microcomputers. They are one of the most widely used computers. They are also fast in terms of speed, memory and data processing. These computers are one of the cheapest computers when compared to all other models. The microcomputers are specially designed for general usages like entertainment, education and working in offices. There are companies who manufacture microcomputers like Sony, Samsung, Toshiba, Dell, Apple etc.
Workstations are the special type of computers which is mainly used for engineering applications such as CAD, CAM, and software development. These computers generally require high-quality graphics and high computing power. Workstations generally come with a high-resolution screen, in-built network support and huge memory. Most workstations have large storage spaces. Some special type of workstations are called diskless workstations and they generally come without a disk drive. Common operating systems used in workstations are like Windows and UNIX. Workstations are also a type of personal computer which is operated by the single user.
But these are typically linked through a local network. Even they can be used in standalone conditions.
6. SERVER COMPUTER
The server is the main computer for a particular company which contains all the collection of data and programs. Multiple users can store, use and share the data among the specified local network. Different types of servers are like a file server and application server. This computer is several steps under the supercomputer. Because they will not try to solve any complex problems as supercomputers. Servers try to send the data according to the user requirements.
