5. 1. Introduction We are going to learn about the following types of computers. Carry up your hand if you know any of these computers. Supercomputers Minicomputers Microcomputers Laptops/notebooks Mainframe computer Embedded computers Terminals Cloud computing

6. Man is still the most extraordinary computer of all. John F. Kennedy

7. Those who can imagine anything, can create anything. Alan Turing

8. 2. Types of Computer 1. Mainframe 2. Super Computer 3. Mini Computer 4. Micro Computer

9. 2.1. Mainframe Computer Main frame computers are known as “Colloquially” means big iron . Mainframe systems are some of the most important aspects of many major businesses. Not only can they process massive amounts of information, but they can do so relatively quickly. For that reason, many of the largest sectors invest in the technology as a way to easily process billions of transactions a week . Mainframe computers are utilized by large industries because they are some of the only hardware that can easily process massive amounts of transactions .

10. 2.1.1 Uses of Mainframe Computer 1 . E-Business And E-Commerce 2. Banking 3. Health Care 4. The Military 5. Academics And Research 6. Retail

11. 2.1.2 Examples of Mainframe Computer Tianhe-1A ; NUDT YH Cluster Jaguar; Cray XT5 Nebulae; Dawning TC3600 Blade TSUBAME 2.0; HP Cluster Platform 3000SL Hopper; Cray XE6 System z9 System z10 servers HP mainframe IBM 370, S/390

12. Knowledge created a new culture of business derived from the information gathering and analysis capabilities of first the mainframe and then the PC Steven Sinofsky

13. 2.2. Super Computer The most powerful computers in terms of performance and data processing are the Supercomputers. These are specialized and task specific computers used by large organizations. These computers are used for research and exploration purposes, like NASA uses supercomputers for launching space shuttles, controlling them and for space exploration purpose . The supercomputers are very expensive and very large in size . It can be accommodated in large air-conditioned rooms; some super computers can span an entire building.

14. 2.2.1. Uses of Super Computer Space Exploration Supercomputers are used to study the origin of the universe, the dark-matters. For these studies scientist use IBM’s powerful supercomputer “Roadrunner” at National Laboratory Los Alamos. 2. ​ Earthquake Studies ​Supercomputers are used to study the Earthquakes phenomenon. Besides that supercomputers are used for natural resources exploration, like natural gas, petroleum, coal, etc. 3. ​ Weather Forecasting Supercomputers are used for weather forecasting, and to study the nature and extent of Hurricanes, Rainfalls, windstorms, etc. 4. Nuclear Weapons Testing Supercomputers are used to run weapon simulation that can test the Range, accuracy & impact of Nuclear weapons. In Pakistan Supercomputers are used by Educational Institutes like NUST for research purposes. Pakistan Atomic Energy commission & Heavy Industry Taxila uses supercomputers for Research purposes.

15. Your brain is a supercomputer and your self talk is the program it will run Jim Kwik

16. 2.3. Mini Computer Minicomputers are used by small businesses & firms. Minicomputers are also called as “Midrange Computers”. These are small machines and can be accommodated on a disk with not as processing and data storage capabilities as super-computers & Mainframes .  These computers are not designed for a single user. Individual departments of a large company or organizations use Mini-computers for specific purposes. For example, a production department can use Mini-computers for monitoring certain production process.

18. 2.4. Micro Computer PC  is an abbreviation for a Personal Computer, it is also known as a Microcomputer . Its physical characteristics and low cost are appealing and useful for its users. The capabilities of a personal computer have changed greatly since the introduction of electronic computers. Today a personal computer is an all-around device that can be used as a productivity tool, a media server and a gaming machine. The modular construction of the personal computer allows components to be easily swapped out when broken or upgrading.

20. 2.4. Micro Computer Desktop computers, laptops, personal digital assistant (PDA), tablets & smartphones are all types of microcomputers. The micro-computers are widely used & the fastest growing computers. These computers are the cheapest among the other three types of computers. The Micro-computers are specially designed for general usage like entertainment, education and work purposes. Well known manufacturers of Micro-computer are Dell, Apple, Samsung, Sony & Toshiba. Desktop computers, Gaming consoles, Sound & Navigation system of a car, Netbooks, Notebooks, PDA’s, Tablet PC’s, Smartphones, Calculators are all type of Microcomputers.

21. “ Being in the   microcomputer  business is like going 55 miles an hour 3 feet from a cliff. George Morrow

22. 3. LATEST COMPUTERS

23. 3.1. Workstations Workstations  are high-end, expensive computers that are made for more complex procedures and are intended for one user at a time. Some of the complex procedures consist of science, math and engineering calculations and are useful for computer design and manufacturing. Workstations are sometimes improperly named for marketing reasons. Real workstations are not usually sold in retail, but this is starting to change; Apple's Mac Pro would be considered a workstation. The movie Toy Story was made on a set of Sun ( Sparc ) workstations  [1] Personal Computer or PC

24. 3.2. Smartphones Do you own a smartphone? Your smart phone is a computer! Most smartphones run iOS or Android. Android is an operating system that is based on  Linux . Smartphones are becoming exponentially faster and also have an exponentially increasing data capacity. These two devices have many limitations such as processing power, memory, energy usage and screen size. They also have different input methods such as (1) numeric keypad (2)small QWERTY keypad with navigation keys or touch gestures, (3) an onscreen and (4) voice input

26. Infographic Style Infographic Style Embedded Computers Embedded computers can be compared to "computers on a chip ". All in one so to speak. You will find them in all kind of apparels that surround us. Washing machines, ticket machines at the subway, camera's, cars, motors, sewing machines, clocks. Everywhere needing something to regulate, control of check something. Historically , embedded computing is associated with self contained preprogrammed computing. Meaning there are mostly no connections outside the environment where that particular type of computing takes (physically) place and influences the working of that embedded computing device.

27. Infographic Style Infographic Style Cloud Computers Cloud computing is the delivery of on-demand computing services -- from applications to storage and processing power -- typically over the internet and on a pay-as-you-go basis . Rather than owning their own computing infrastructure or data centers, companies can rent access to anything from applications to storage from a cloud service provider . One benefit of using cloud computing services is that firms can avoid the upfront cost and complexity of owning and maintaining their own IT infrastructure, and instead simply pay for what they use, when they use it.

28. According to size Computer is divided into how many types? Let’s RECAP The Computer is classified into 4 tyes According to size: Mainframe Computer, Super Computer, Mini Computer and Micro Computer

29. Can you differentiate the super Computer and Mainframe Computer? Let’s RECAP Complex Problems vs Large Storage Speed: BIPS vs MIPS Size: Larger vs smaller Cost: expensive vs less expansive Operating System (O.S) : Linux vs multi operating System Built :Specific vs general purpose

30. What is the advantage of using Cloud Computing? Let’s RECAP Reduced IT costs Scalability Business continuity Collaboration efficiency Flexibility of work practices Access to automatic updates
