What is a Computer?A computer is an electronic device that manipulates information, or "data." It has the ability to store, retrieve, and process data. You can use a computer to type documents, send email, and browse the internet. You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more.Slide3
There are four (4) types of computers that were designed by mankind. These include:
SupercomputersMainframe computers
MinicomputersMicrocomputersSlide4
SupercomputersA supercomputer is a computer that performs at or near the currently highest operational rate for computers. A supercomputer is typically used for scientific and engineering applications that must handle very large databases or do a great amount of computation (or both).
It was first created in 1960.Slide5Slide6
SUPERCOMPUTERSAdvantages
Decreasing Processing TimeSolving New ProblemsLowering CostsImproving SafetyHigh CapacityDisadvantagesStorage and BandwidthMaintenance and SupportExpensiveProcessing TimeSlide7
UsesA supercomputer is used for:
Processing of information on quantum mechanicsLarge scale weather forecastingMolecular studiesPolymer researchTo solve mathematical problemsWind
tunnel researchChemical composition. Slide8
Main FramesA data processing system employed mainly in large organizations for various applications, including bulk data processing, process control, industry and consumer statistics, enterprise resource planning, and financial transaction processing.Slide9Slide10
Main FramesAdvantages
Supports thousands of transactions per second.Can serve thousands of users and applications simultaneously.Able to manage huge amounts of data.More reliable and secure than client-server networks.Backwards compatibility with legacy mainframe software, which is useful if your organization has already invested heavily in mainframe computing.
DisadvantagesRequires backwards-compatibility with Mainframe Operating Systems.Dedicated staff are needed to run the system.Initial start-up costs can be high, compared to client-server networks - which can start small and be expanded later. A small client-server system might be all you need.By default, there is no geographical distribution built into the system, and this is something that client-server networks are designed for
.
They can take up a lot of space and require dedicated environmental management, for example, cooling systems.Slide11
UsesBusinesses and large institutions often use mainframe computers as network servers for their personnel workstations. Because of their massive capacity for memory and storage, they are also commonly used as web servers

MinicomputersA minicomputer is a type of computer that possesses most of the features and capabilities of a large computer but is smaller in physical size.
Minicomputers are mainly used as small or midrange servers operating business and scientific applications. However, the use of the term minicomputer has diminished and has merged with servers. Slide13Slide14

MicrocomputersA microcomputer is a complete computer on a smaller scale and is generally a synonym for the more common term
, personal computer or PCs, a computer designed for an individual. Slide17Slide18
Microcomputers Advantages

Uses HomeFamilies use microcomputers for education; software can hold thousands of book volumes worth of information.
Businesses Took a huge leap forward in bookkeeping, inventory and communication when microcomputers were made readily available.Medical UsesThe first microcomputer (dubbed the "Sac State 8008") was built specifically for storing medical records. Before microcomputers were available, medical records were stored in paper form. Microcomputers make it possible to download patients' medical histories.Slide20
Now let’s recap!!!What is a Computer?List the types of computersGive a disadvantage and an advantage of each.Slide21
