Computers have wide uses in our daily life—from scientific data recording to engineering to everyday personal use. The applications and benefits of computer are increasing day by day. There are many types of computers which performs different tasks such as weather monitoring and tracking to processing simple tasks such as surfing the Internet and checking email.
Some of them are as follows.
Supercomputers

" Seymour Cray" built the first supercomputer in 1963 called the CDC 6600. Supercomputers provide the fastest processing speed of any computer. Used for highly complex calculations, supercomputers possess extreme processing capabilities. For example, the Jaguar, a Cray Inc. supercomputer, operates at 1750 Teraflops (floating point operations per second) at peak performance—which means the system can calculate 1,750,000 Gigabytes per second. Supercomputers work behind the scenes to drive the most advanced information research forward. They are used for various highly specified applications including weather research, quantum physics, nuclear weapon detonation simulations and a class of problems called the "Grand Challenge problems," a set of problems requiring a high-performance computer.
Minicomputers
The mid-range computer and currently called a server, is between a microcomputer and mainframe computer. The term "minicomputer" developed during the 1960s to describe computers that utilized transistor technology. During the 1970s and 1980s, the development of microcomputers—or desktops—placed minicomputers in the mid-range designation. They were considered a more powerful single-user machine. True minicomputers began to decline, however, due to a less-expensive minicomputer that used microprocessor technology. Mid-range computers provide processing services for several applications. They are used to run back-end applications such as enterprise email, database systems and network-wide antivirus software.
Microcomputers or PC
Considered the first desktop, the HP 9830, which was released for consumer use in the 1970s, surpassed computers at the time because it featured a hard drive and utilized the BASIC programming language. Microcomputers are the most common consumer device. This computer type includes desktop personal computers and laptops. Microcomputers use a microprocessor to execute instructions and are designed for use by one individual. They are used for office applications, email, Internet access, gaming or education.
