3 What do you know about the following? Supercomputer Mainframe Minicomputer Personal Computer (PC) CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

4 There are different types of computer of varying size and power, including the following: Supercomputer This is the most powerful type of mainframe. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

5 What Are the Uses of a Supercomputer? Since its creation in the 1960s, the supercomputer has been used by a variety of large companies and colleges in an effort to conduct research that otherwise would not be possible. Because supercomputers can crunch numbers at a far superior rate than humans as well as work in a multidimensional way, the devices are essential to modern studies and research.

6 What Are the Uses of a Supercomputer? Quantum Mechanics Supercomputers are used heavily in the processing of information on quantum mechanics. They are used to study physical systems at the atomic level. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

7 What Are the Uses of a Supercomputer? Weather Large-scale weather forecasting, such as that of global climate change, needs to use supercomputers in order to take into account globally changing conditions. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

8 What Are the Uses of a Supercomputer? Modeling Intensive modeling is conducted using supercomputers. This is useful for molecular studies, polymer research, chemical composition and simulations such as wind tunnel research. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

9 What Are the Uses of a Supercomputer? Military Military applications are very elaborate. From organizing war games to studying the effects of nuclear detonations on a large scale, many militaries across the planet use supercomputers. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

10 What Are the Uses of a Supercomputer? Grand Challenge Unsolved problems (known as "Grand Challenge" problems) are frequently the subject of supercomputer use. Examples of this include mathematical problems and protein-folding techniques. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

11 Another large and very powerful computer type is… Mainframe Its large, very powerful, multi-user i.e. can be used by many people at the same time, multi-tasking i.e. can run many programs and process different sets of data at the same time. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

12 Mainframe computers Mainframes (often referred to as Big Iron) are used mainly by large organizations for critical applications, typically bulk data processing such as census, industry and consumer statistics, enterprise resource planning, and financial transaction processing. CANKAYA UNIVERSITY - OFFICE OF BASIC AND ELECTIVE COURSES- ENGLISH UNIT

13 Minicomputers A minicomputer is a class of multi-user computers that lies in the middle range of the computing spectrum, in between the largest multi-user systems (mainframe computers) and the smallest single-user systems (microcomputers or personal computers).
