BTEC Computing Unit 2 Review Practice
Test.
Utility software - CORRECT ANSWER Software used by the OS to help manage resources and services for
computer systems.
Features of utility software - CORRECT ANSWER Security, Connectivity, Back up and Restore.
Uses of utility software - CORRECT ANSWER Data compression, Disk defragmentation, Data encryption,
Back up, Anti-virus software and registry cleaners.
Factors affecting performance of utility software - CORRECT ANSWER CPU, GPU and Memory.
Factors affecting choices of utility software - CORRECT ANSWER Cost, Ease of use and Availability.
Application software - CORRECT ANSWER Computer program used to perform functions and activities
for the user.
Features of application software - CORRECT ANSWER Storage of data, Creating and editing documents,
GUI and Menus.
Uses of application software - CORRECT ANSWER E-mail, Word processing, Database programs,
Spreadsheet programs and Desktop publishing.
Factors affecting performance of application software - CORRECT ANSWER Complexity, Design, The
network, Ability to use memory efficiently and The processing required.
Factors affecting choices of application software - CORRECT ANSWER Cost, Ease of use, Availability and
Design.
Principles of open source - CORRECT ANSWER Free, Interchangeable for anyone.
, Implications of open source - CORRECT ANSWER can be copied, less secure and can be edited by anyone
with access to the code.
CPU (Central Processing Unit) - CORRECT ANSWER The CPU is the part of the computer where
operations are managed and executed. Performance is measured by instructions executed per unit time.
Hardware used in output devices - CORRECT ANSWER These are used to get anything out of the
computer/ provide data to the user
- Printers
- Screens
- Projectors
- Speakers
Backing storage types e.g USB memory stick - CORRECT ANSWER External hardware for example optical
disks (CDs). USB memory sticks: a removable device that can store data, measured in gigabytes and
terabytes. Capacity typically starts at 2GB but can go as high as 512GB or 1TB. 2.0 USB can transfer data
at 60 megabytes per second. 3.0 USB can transfer up to 640 megabytes per second.
Multi-functional device - CORRECT ANSWER These are devices that perform multiple functions, for
example a printer.
Motherboard - CORRECT ANSWER A circuit board, located on the bottom or at the back of the computer
chassis which has connectors for other circuit boards and the principal components of a computer to be
slotted into. Allows communication to the CPU, RAM, as well as all other computer hardware
components.
Personal computer - CORRECT ANSWER A computer widely used for work and used by individuals.
Power Supply (PSU) - CORRECT ANSWER Supplies power to a computer. Usually, personal computers can
be plugged into standard electrical outlets where the power supply then pulls the required amount of
electricity and coverts the current from AC to DC.
