What are some examples of internal hardware devices?
Motherboard
CPU
RAM

What is RAM?
RAM is an internal chip which stores any part of the operating system currently in use. It is volatile
What is CPU?
CPU has ALU where arithmetic and logical operations are carried out. It also has CU which takes instructions, then decodes and executes them.
What is ROM?
ROM is a memory used to store information that needs to be permanent. ROM is non-volatile so the data stored is not lost even after the power is lost.
What is NIC?
NIC allows a computer or any other device to be connected to a network, wired or wireless.
What is a graphics card?
A graphic card allows the computer to send graphical information to video display devices. A graphic card contains, a processing unit, a memory unit, a cooling mechanism and connections to a display unit.
What is sound card?
Sound card is a ability to produce sounds.
What is HDD?
HDDs are magnetic in nature and are one of the main methods for storing data.
What is SSD?
SSDs are the newer storage system which makes use of SDD technology.
What is software?
Software is the general term used for the programs that control the system and process data.
What are some examples of software data?
Word processing
Database
Spreadsheet
Video editing
Graphics editing
Apps
Audio editing
CAD
Control and measurement software
What is system software?
System software is the software designed to provide a platform for other software to run.
What is word processing?
Word processing creates, edits, saves and manipulates texts. It has spell checkers, thesaurus and copy and paste functions. It can translate into a foreign language and import pictures into a structured page format.
What is spreadsheet?
Spreadsheets use formulas to carry out calculations. They have the ability to produce graphs, model them and do ‘what if’ calculations.
What is data base?
Data base is used to organize, manipulate and analyze any data. It can also carry out and edit queries on DBMS.
What are apps?
Apps refer to software which can perform a fairly substantial task.
What is control and management software?
It is designed to allow a computer or a microprocessor to interface with sensor.
What is CAD?
CAD is a software used to help in the creation, manipulation, modification and analysis of a design.
What can an audio editing software do?
It can alter the length and volume of the track, reduce noise and create another version of the sound track.
What can an video editing software do?
It allows a user to manipulate videos to produce a new video.
What can a graphics editing software do?
It allows bitmap and vector images to be changed.
What is a compiler?
A compiler is a computer program that translates a program written in a HLL into machine code. The original program is called source code and the end result is called object code.
What are linkers?
A linker is a computer program that takes one or more object files produced by a compiler and combines them into a single program that can be run on computer.
What is a device driver?
A device driver is the name given to software that enables one or more hardware devices to communicate with the computer’s operating system.
What is OS?
It is a software that is essentially running in the background of the computer system to make the computer user-friendly.
What are utitlities?
Utility programs are software that has been designed to carry out specific tasks in the computer, such as; antivirus, disk repair, security and file management.
