TYPES OF COMPUTERS

Computers come in different sizes with varying capabilities forprocessing information

FLOPS (Floating point operations per second)

PDAs, handheld mobile devices

PCs

Workstation

More powerful mathematical and graphics-processing capabilities than a PC

Servers

Type of midrange computer

Support computer network, sharing files and resources

Provide hardware platform for e-commerce


8/44

Mainframes

Large-capacity, high-performance computer that can process large amounts ofdata very rapidly

E.g. used by airlines for thousands of reservations per second

Supercomputer

More sophisticated computer used for tasks requiring extremely rapid andcomplex calculations with thousands of variables, millions of measurements

Used in engineering, scientific simulations, military/weapons research,

weather forecasting

Grid computing

Power of geographically remote computers connected into single network toact as virtual supercomputer

Contemporary Hardware Trends

The Emerging Mobile Digital Platform

Nanotechnology

Creating computer chips and other devices thousands of times

smaller through manipulating individual atoms, molecules


16/44

Nano tubes are tiny tubesabout 10,000 times thinner

than a human hair. They

consist of rolled up sheets

of carbon hexagons, have

potential uses as minuscule

wires or in ultra small

electronic devices, and are

very powerful conductors

of electrical current.


17/44

Edge computing

Multitier, load-balancing scheme for Web-based applications

Significant parts of Web site content, logic, and processingperformed by smaller, less expensive servers located nearby theuser

Increases response time and resilience and lowers technologycosts.

Autonomic computing Development of systems that can configure themselves, heal

themselves; e.g. self-updating antivirus software


18/44

Edge Computing


19/44

Virtualization

Process of presenting a set of computing resources so they can be

accessed in ways that are unrestricted by physical configuration or

geographic location Server virtualization: Running more than one operating system at

the same time on single machine.
