Computer Science Principles
Quarter 1 Test Questions and
answers (verified for accuracy)
Bit - answer A binary digit, or bit, is the smallest unit of information in a
computer. It is used for storing information and has a value of true/false, or
on/off. An individual bit has a value of either 0 or 1, which is generally used
to store data and implement instructions in groups of bytes.
Error detection and correction - answer It is possible in theory that a single
bit of a big message will arrive incorrectly. But networks don't just pass bits
from one place to another. They check to see if the bits seem to have been
damaged in transit, and correct them or retransmit them if they seem
incorrect
Moore's Law - answer Authored by Gordon Moore, it is a principle that states
that the processing power of a computer will, on average, double every two
years.
Disruptive Technology - answer refers to any enhanced or completely new
technology that replaces and disrupts an existing technology, rendering it
obsolete
Binary - answer A way of representing information using only two options.
Innovation - answer A new or improved idea, device, product, etc, or the
development thereof.
Bandwidth - answer Transmission capacity measure by bit rate.
, Bit rate - answer The number of bits that are conveyed or processed per unit
of time. e.g. 8 bits/sec.
Latency - answer Time it takes for a bit to travel from its sender to its
receiver.
Protocol - answer A set of rules governing the exchange or transmission of
data between devices.
Data - answer Facts and statistics collected together for reference or analysis
Character - answer In terms of computing, it is any letter, number, space,
punctuation mark, or symbol that can be typed on a computer. The word
"computer" for example, consists of eight characters. The phrase "Hi there."
takes up nine characters. Each character requires one byte of space, so
"computer" takes up 8 bytes. The list of characters that can be typed is
defined by the ASCII and extended ASCII set.
ASCII - answer American Standard Code for Information Interchange. This is
the universally recognized raw text format that any computer can
understand.
IETF - answer Internet Engineering Task Force - develops and promotes
voluntary Internet standards and protocols, in particular the standards that
comprise the Internet protocol suite (TCP/IP).
Byte - answer a group of 8 bits
Internet - answer A group of client and server computers that are connected
to each other
Net Nuetrality - answer The principle that all Internet traffic should be treated
equally by Internet Service Providers.
