Computers 101

Understanding Digital

Variation A

A way of transmitting or storing data using
"on" and "off" bits, expressed as "1" or "0."

Variation B

Defines any system based on discontinuous
data or events. Computers are digital machines
because at their most basic level they can
distinguish between just two values, "0" and "1",
or "off" and "on". There is no easy way to
represent all the values in between, such as 0.45.
All data that a computer processes must be encoded
digitally, as a series of zeroes and ones.

Variation C

A description of data which is retained or transmitted
as a sequence of discrete symbols from a finite
set, most commonly this means binary data
represented using electronic or electromagnetic
signals. The antonym is analogue.

Variation D

Representing or operating on data or information
in numerical form.

Variation E

Of or relating to a device that can read, write,
or retain information that is represented in
numerical form.

Variation F

Involving or using numerical digits expressed
in a scale of notation to represent discretely all
variables occurring in a problem.
