QUESTIONS AND CORRECT ANSWERS
GRADED A+
◉ COBOL. Answer: The first computer language; developed in the
1950s; still used today.
◉ Fourth generation computer languages (4GL). Answer: software
tools that help reduce the amount of procedural knowledge that is
needed about how computers operate and lets end users create
programs as needed; SQL is a 4GL.
◉ Structured Query Language (SQL). Answer: A computing language
that is used with relational databases.
◉ Dynamic Random-Access Memory (DRAM). Answer: The main
memory of a computer system; requires constant refreshing.
◉ Static Random-Access Memory (SRAM). Answer: Retains memory
for as long as power is being supplied; does not need to be
constantly refreshed; used to access the most frequently used data,
as it is faster.
,◉ Horizontal Application. Answer: Software that provides solutions
based upon the common needs of many businesses.
◉ Vertical Application. Answer: Software that designed for a specific
business.
◉ Software. Answer: Provides instructions to computers to perform
tasks.
◉ Low-Level Programming Language. Answer: Basic programming
languages that used machine language instruction; they are specific
to the hardware and lack portability.
◉ Dumb Terminal/Thin Client. Answer: A terminal that depends on
the host computer for its processing power
◉ optical character recognition (OCR). Answer: Reads machine
printed text; used for time cards.
◉ Intelligent Character Recognition (ICR). Answer: Reads
handwritten text; more advanced form of optical character
recognition (OCR).
,◉ UNIX. Answer: An operating system designed to code computer
instructions in a mainframe environment.
◉ Workstation. Answer: A powerful computer system that can
handle intensive mathematical operations; often used by engineers.
◉ Mashup. Answer: Occurs when software is mixed and matched to
develop a customized application
◉ Field. Answer: An attribute of an entity, such as name, address, or
student ID.
◉ Tuple/Record. Answer: A record of data set in a row.
◉ Query Language. Answer: Provides instructions and procedures to
retrieve data from a database.
◉ Primary Key. Answer: A field that uniquely identifies a record,
such as customer ID or student ID.
◉ Foreign Key. Answer: Field that is a primary key to another table.
◉ Schema. Answer: The complete description of the database.
, ◉ Variable. Answer: a data type or simply type is a classification of
data which tells the compiler or interpreter how the programmer
intends to use the data; can become incompatible with data
warehouse design.
◉ Flat File Database. Answer: Stores data in plain text, holding one
record; cannot contain multiple tables like a relational database.
◉ Online Analytical processing (OLAP). Answer: analyze transaction
data used for making decisions; multidimensional (cubical) data;
requires a lengthy, complex loading and updating phase.
◉ Online transaction processing (OLTP). Answer: database design
used for browsing and manipulating business transaction activity.
Processing of information into the database.
Don't perform analyses on these databases because it could affect
performance.
◉ relational database. Answer: type of database in which multiple
information files are combined into one database in one location,
where data are stored in two-dimensional tables known as relations
and contain multiple entities and attributes
