Computers
Presented : ANSIF EK
Digital computers are programmable machines that use electronic technology to generate, store and process data. Two terms, positive "1" and nonpositive "0," compose the data into a string.
What is “Digital Computer” ?
Digital Computer
Micro computer
Supercomputer
Mainframes
Minicomputer
Microcomputers
A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and input/output devices.
Also known as “personal computer” Includes workstations ,desktops ,servers,
laptop and notebook Examples are the IBM pc,
Apple Macintoshes, Dell.
Microcomputers
MINICOMPUTER
Minicomputers emerged in the mid-1960s and were first developed by IBM Corporation.
This computer fills the space between the mainframe and microcomputer
This may also be called a mid-range computer.
Minicomputers may contain one or more processors, support multiprocessing and tasking, and are generally resilient to high workloads.
Example are DEC’S, VAX, RANGE.
MINICOMPUTER
Mainframes Computer
Mainframes are a type of computer that generally are known for their large size, amount of storage, processing power and high level of reliability. They are primarily used by large organizations for mission-critical applications requiring high volumes of data processing.
Ability to run (or host) multiple operating systems.
Mainframes first appeared in the early 1940s.
The Market is dominated by IBM
Mainframe computer
Supercomputers
supercomputers consists of tens of thousands of processors that are able to perform billions and trillions of calculations or computations per second.
Supercomputers are primarily are designed to be used in enterprises and organizations that require massive computing power
As of 2013, IBM Sequoia is the fastest supercomputer to date. It has more than 98,000 processors that allow it to process at a speed of 16,000 trillion calculations per second.
Supercomputers
they contain most of the key components of a typical computer, including a processor(s), peripheral devices, connectors, an operating system and applications.
A large and very powerful mainframe computer is called a supercomputer. The Cray X-MP is an example of supercomputer. Such supercomputers are applied to the solution of very complex and sophisticated scientific problem and for national security purposes of some advance nations.
