Give two examples of computer related scenarios that exemplify: Abstraction (two examples) Virtualization (two examples)

Solution

Abstraction:

Abstraction is a technique for arranging complexity of computer,systems.

->In operating system an abstraction is a software that hides lower level details and provide a set of high level functions.

Example:

Two functions perform almost the same task and can be combined in to a single function.

Example2:clavinoxsoftware is middleware which provides os abstarction targetting wireless embedded device and system development.

->It comprises wireless protocols stacks development tools and memory management techniques in addition to the support of desktop and range of realtime operating system.

(b)Virtualization:

Virtualization refers to the act of creating a virtual version o something.

->including virtual computer hardware platforms,storage devices,commputer network resources.

->Operating system level virtualization hosting of multiple virtualized enviroment with in a single os instance.

->some virtualizatio in operating system are

•Application virtualization

•service virtualization

•memory virtualization

•storage virtualization

•data virtualization

•network virtualization and etc.

Examples:

•computer based exams like GMAT,CAT

•Smart glasses

•smart watches

•most the app like the number of miles you walk is not stored on phone memory but on other server and moreover all the calculations are done by a software.
