ANSWERS ALREADY PASSED
◉ Decomposition. Answer: breaking a problem down into smaller,
more manageable parts, which are then easier to solve.
◉ Back up. Answer: a copy of files in another location so that they
are still available if the original copy is damaged or lost. Backing up
is the process of making a backup copy.
◉ Access control. Answer: this determines which users have access
to which data, and what they are allowed to do with it.
◉ Algorithm. Answer: a precise method for solving a problem. It
consists of a sequence of step by step instructions.
◉ Analogue. Answer: using signals or information represented by a
quantity (e.g. an electric voltage or current) that is continuously
variable. Changes in the information being represented are indicated
by changes in voltage. This method requires very accurate sending
and receiving mechanisms.
,◉ Application software. Answer: software that performs a task that
would otherwise be done by hand, perhaps with pen and paper.
◉ Arithmetic/logic unit (ALU). Answer: the part of the CPU that
performs calculations and logic operations.
◉ Arithmetic operator. Answer: an operator that performs a
calculation on two numbers.
◉ Arithmetic shift. Answer: used for signed binary numbers. When
performing a right shift the bits at the left are replaced by copies of
the most significant bit.
◉ Array. Answer: an organised collection of related values that share
a single identifier.
◉ Ascending order. Answer: this is arranging items from smallest to
largest (e.g. 1, 2, 3, 4, 5, 6 or a, b, c, d, e, f).
◉ Assembly language. Answer: a low-level language written using
mnemonics.
, ◉ Assignment statement. Answer: the SET. . .TO command is used tc
initialise variables in pseudo-code, for example, SET anotherGo TO 0
,SET correct TO False
◉ Attribute. Answer: an item of data stored about an entity.
◉ Audit trail. Answer: a record of activities that have taken place on
a computer system. This record is generated automatically and will
record what has happened and who or what made the change.
◉ Authentication. Answer: the process of proving to a computer
system who you are (e.g. using a username and password).
◉ Bandwidth. Answer: the amount of data that can be carried on a
network in a given period of time.
◉ Binary. Answer: information represented by only two values (e.g.
a voltage or no voltage, on or off). There are no communication
errors or misunderstandings because there are no small differences.
◉ Binary digit or bit. Answer: the smallest unit of data that is
represented in a computer. it has a single binary value, either 1 or 0.
◉ Binary prefix. Answer: multiplies a unit by powers of 2.
