According to physical size, computers are classified into the following types:
Supercomputer: Supercomputers are the fastest and the most expensive type of computer. They are large and require more space for installation. These types of computers are mainly designed to perform massive data-based and complex tasks. Supercomputers are capable enough to handle trillions of instructions at the same time.
Mainframe Computer: Mainframe computers are comparatively smaller in size as compared to supercomputers. However, they are not much small. These types of computers are designed to perform hundreds or thousands of jobs at a time simultaneously. These computers can handle heavy tasks, including complex calculations and can store vast amounts of data. They are best suited for big organizations such as banking, telecom, and educational sectors.
Microcomputer: Microcomputers are cheap in price and support multi-user platform. These are the general-purpose computers designed to handle all the necessary tasks of individual needs. Since they are comparatively slower than mainframe computers, thereby are suitable for small organizations. They are best suited for internet café, schools, universities, offices, etc. A microcomputer is also referred to as the ‘Personal Computer (PC)’ in general life. Laptop and desktop are examples of microcomputers.
Minicomputer: Minicomputers are also referred to as Miniframe computers. These are the midsize multiprocessing computer designed purposely for easy carry. These types of computers are light-weight and can fit in a small space. They are suitable for billing, accounting, education, and business purposes. Since these minicomputers are easy to carry, they are the best option for those who need a computer while traveling. Tablet PC, Notebooks, and cell phones are examples of minicomputers.
Workstation: Workstation is a powerful, single-user computer. A workstation is a personal computer with a faster microprocessor, a massive amount of RAM, higher-quality monitors, high graphic memory, etc. This is best suited for performing any specific type of task professionally. According to the type of tasks, a workstation can be referred to as a music workstation, graphic workstation, or engineering design workstation. Most businesses and professionals use workstations for performing tasks like animation, music creation, video editing, poster designs, data analysis and more.
