- 8SSD is?Solid-state drive
- 9Software is ?Software is a general term for the programs
that control the computer system. - 10Two types of softwaresApplication
&
System - 11What is an application software?Programs that allow
users to do specific tasks - 12Examples of application softwaresWord processor
Spreadsheet
Database
Apps
Video editing
Graphics editing
Computer-aided design (CAD) - 13Functions of a word processor- Used to manipulate text documents, such as an essay or a report.
- Creating, editing and manipulating text
- Copy and paste function
- Spell checker and thesaurus
- Importing photos/images
- Translation into other languages
(basically Microsoft Word) - 14Functions of a spreadsheet- Used to organize and manipulate numerical data.
- use of formulas to carry out calculations
- produce graphs
- do modelling and ‘what if’ conditions
(basically Microsoft Excel) - 15Functions of a database- Used to organize, manipulate and analyze data.
(A typical database is made up of one or more tables. Each row is called a ‘record’ and each column is called a ‘field’.)
- carry out queries on database data and produce a report
- add, delete and modify data in a table
(smth like the accounting one in office?) - 16Definition of an app- the type of software that runs on mobile phones or tablets.
- Usually downloaded from an ‘App Store’ and range from games to sophisticated software such as phone banking.
Examples
video and music streaming,
GPS (global positioning system), and
camera facilities. - 17Examples of appsvideo and music streaming
GPS (global positioning system)
camera facilities - 18Functions of graphics editing softwareAllows bitmap and vector images to be
changed. - 19BITMAP can?can change the pixel brightness and colour to produce a different image.
- 20VECTOR can?manipulates lines, curves and text to alter the stored image and do not use pixels.
- 21Functions of video editing software- Allows a user to manipulate videos to produce an edited video.
- rearranging, adding and/or removing sections of video clips and/or audio clips,
- applying colour correction, filters and other video enhancements, and
- creating transitions between clips in the video footage. - 22Functions of photo editing software- Allows a user to manipulate digital
photographs stored on a computer. E.g.
change brightness, contrast, colour saturation or remove ‘red eye’.
- allows a photographer to remove unwanted items and generally ‘touch up’ a photo to make it as perfect as possible. - 23Control and measuring software is?A software designed to allow a computer or microprocessor to interface with sensors so that it is possible to:
- measure physical quantities in the real world (such as temperatures), and
- control applications (such as a chemical process) by comparing sensor data with stored data and sending out signals to alter process parameters (for example, open a valve to add acid and change
the pH). - 24What is a system software?Programs that allow the
hardware to run properly
and allow the user to
communicate with the
computer - 25Examples of system softwareCompiler
Linkers
Device driver
Operating systems (OS)
Utilities - 26Compiler is?A computer program that translates a
program written in a high-level language into machine code so that it can be directly used by a computer to perform a required task.
The original program is called the source
code. The code after compilation is called the object code. - 27Examples of compilersJava
Python
Visual Basic
Fortran
C++
