COMPUTER SCIENCE AN OVERVIEW
CHAPTERS 1 TO 8 REVIEW PAPER 2026
COMPLETE QUESTIONS WITH EXPERT
SOLUTIONS AND MARKING SCHEME
◉ ROM.
Answer: The computer's "built-in" memory containing data that
normally can only be read, not written to. It contains the
programming that allows your computer to be "booted up" each
time you turn it on.
◉ RAM.
Answer: The physical hardware inside a computer that temporarily
stores data, serving as the computer's "working" memory. Volatile
◉ operating system.
Answer: Often abbreviated as O.S., this is a powerful, and usually
large program that controls and manages the hardware and other
software on the computer. Examples: Windows, iOS, and Linux
◉ computer.
Answer: An electronic device that manipulates information, or data.
It can store, retrieve, and process data. It is a programmable
,machine. This means it can execute a programmed list of
instructions and respond to new instructions that it is given.
◉ hardware.
Answer: The collection of physical parts of a computer system.
◉ software.
Answer: organized information in the form of operating systems,
utilities, programs, and applications that enable computers to work.
◉ Artificial Intelligence.
Answer: The theory and development of computer systems able to
perform tasks that normally require human intelligence, such as
visual perception, speech recognition, decision-making, and
translation between languages.
◉ the Turing test.
Answer: A test for intelligence in a computer, requiring that a human
being should be unable to distinguish the machine from another
human being by using the replies to questions put to both. This was
originally called "The Imitation Game." You performed this test using
ELIZA, Chomsky, and 20 Questions.
◉ ELIZA.
, Answer: In 1965, Joseph Weizenbaum developed this interactive
program that carried on a dialogue in English on any topic. "She"
was designed to mimic a Rogerian psychotherapist. You chatted with
"her" when you did the Turing test worksheet.
◉ search engine.
Answer: is a program that allows you to search the internet for
information
◉ web crawler.
Answer: A search engine makes an index using a program called a ___
(aka spider). This program automatically browses the web and
stores information about the pages it visits. Every time it visits a
webpage, it makes a copy of it and adds its URL to an index.
◉ 5 Characteristics of an Algorithm.
Answer: 1. Effectively computable operations, 2. Halts in a finite
amount of time, 3. Produce a result, 4. Have unambiguous
operations, 5. are well ordered
◉ 3 Advantages of Using the Internet for Research.
Answer: 1. Fast, 2. easy to narrow down results, 3. Information is
very current
