QUESTION 1
Personal Computer(PC)
Correct Answer: A computer designed for use by an individual, usually incorporating a graphics display, a
keyboard, and a mouse.
QUESTION 2
Server
Correct Answer: A computer used for running larger programs for multiple users, often simultaneously, and
typically accessed only via a network.
QUESTION 3
Supercomputer
Correct Answer: A class of computers with the highest performance and cost; they are configured as servers
and typically cost tens to hundreds of millions of dollars.
QUESTION 4
Embedded computer
Correct Answer: A computer inside another device used for running one predetermined application or
collection of software.
QUESTION 5
Personal mobile devices(PMDs)
Correct Answer: Are small wireless devices to connect to the internet; they rely on batteries for power, and
software is installed by downloading apps. Conventional examples are smart phones and tables.

QUESTION 6
Cloud computing
Correct Answer: Refers to large collections of servers that provide services over the internet; some
providers rent dynamically varying numbers of servers as a utility.
QUESTION 7
Software as a Service (SaaS)
Correct Answer: Delivers software and data as a service over the internet, usually via a thin program such as
a browser that runs on local client devices, instead of binary code that must be installed, and runs wholly on
that device. Examples include web search and social networking.
QUESTION 8
Acronym
Correct Answer: A word constructed by taking the initial letters of a string of words. For example: RAM is an
acronym for Random Access Memory, and CPU is an acronym for Central Processing Unit.
QUESTION 9
Terabyte(TB)
Correct Answer: Originally 1,099,511,627,776(2^40) bytes, although communications and secondary storage
systems developers started using the term to mean 1,000,000,000,000(10^12) bytes. To reduce confusion, we
now use the term.
QUESTION 10
Tebibyte(TiB)
Correct Answer: For 2^40 bytes.
