Rationale:
A sound card (also known as an audio card) is an internal computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs. The term sound card is also applied to external audio interfaces that use software to generate sound, as opposed to using hardware inside the PC.

Peopleware
It refers to people involve in the data processing operations such as the system administrator, student and the like.
Peopleware is a term used to refer to one of the three core aspects of computer technology, the other two being hardware and software. Peopleware can refer to anything that has to do with the role of people in the development or use of computer software and hardware systems, including such issues as developer productivity, teamwork, group dynamics, the psychology of programming, project management, organizational factors, human interface design, and human-machine-interaction.

Rationale:
Yes—the operating system is running. Mostly it is managing the user interface, waiting for some input to tell it what to do.

Rationale:
Removable media is any type of storage device that can be removed from a computer while the system is running.

Disadvantage:
1. The problem with paper tape was that it kept on breaking - since the more holes that you punched in it the more fragile it became.
2. Another problem with paper tape was that the large size of the holes on the paper meant that you needed very long lengths of tape to store lots of data or small computer programs.

What is computer software? It is the set of instructions (also called a program) that guides the hardware to operate effectively.

OHSP ICT Module

Rationale:
CRT - (Cathode Ray Tube) display
LCD - (Liquid Crystal Display) as of 2010, it is the primary visual display for personal computers.
LED - (light-emitting diode) display
OLED - Organic Light-Emitting Diode

OHSP ICT Module

Rationale:
Input devices? Yes-various sensors throughout the car deliver data to the computer.
Output Devices? Yes-various actuators have their actions controlled by data.
Main Storage? Yes-probably not very much.
Secondary storage? No.
