CSIS 110 Module 1 Question and
answers verified to pass
data - correct answer In the context of computing and data management,
data refers to the symbols that a computer uses to represent facts and ideas.
data representation - correct answer The use of electronic signals, marks, or
binary digits to represent character, numeric, visual, or audio data.
analog data - correct answer Data that is measured or represented on a
continuously varying scale, such as a dimmer switch or a watch with a sweep
second hand.
digital data - correct answer Text, numbers, graphics, or sound represented
by discrete digits, such as 1s and 0s.
bit - correct answer The smallest unit of information handled by a computer. A
bit is one of two values, either a 0 or a 1. Eight bits constitute a byte, which
can represent a letter or a number.
digitalization - correct answer Converting non-digital information or media to a
digital format through the use of a scanner, sampler, or other input device.
binary - correct answer The representation of data using two states, such as
off-on or 1-0.
file - correct answer A named collection of data (such as a computer
program, document, or graphic) that exists on a storage medium, such as a
hard disk or CD.
, binary number system - correct answer A method for representing numbers
using only two digits: 0 and 1. Contrast to the decimal number system, which
uses ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
file name extension - correct answer The characters in a file name after the
period, such as .exe and .txt.
numeric data - correct answer Numbers that represent quantities and can be
used in arithmetic operations.
file format - correct answer The method of organization used to encode and
store data in a computer. Text formats include DOCX and TXT. Graphics
formats include BMP, TIFF, GIF, and PNG.
character data - correct answer Letters, symbols, or numerals that will not be
used in arithmetic operations (name, Social Security number, etc.).
ASCII - correct answer American Standard Code for Information Interchange)
A code that represents characters as a series of 1s and 0s. Most computers
use ASCII code to represent text, making it possible to transfer data between
computers.
Extended ASCII - correct answer Similar to ASCII but with 8-bit character
representation instead of 7-bit, allowing for an additional 128 characters.
Unicode - correct answer A 16-bit character representation code that can
represent more than 65,000 characters.
