Section A - 7 - Computer Software - Types & Roles of Operat

A research lab has purchased a new mainframe computer to perform massive data processing. What type of operating system is commonly used with this type of device?

• Real-Time Operating Systems

• Single-User, Single-Task Operating Systems

• Single-User, Multi-Tasking Operating Systems

• Multi-User Operating Systems

What type of operating system is commonly used on most personal computers and mobile computing devices?

• Real-Time Operating Systems

• Single-User, Single-Task Operating Systems

• Single-User, Multi-Tasking Operating Systems

• Multi-User Operating Systems

What type of operating system is commonly used in airplanes?

• Real-Time Operating Systems

• Single-User, Single-Task Operating Systems

• Single-User, Multi-Tasking Operating Systems

• Multi-User Operating Systems

Why do powerful computers like servers use multi-user operating systems?

• It allows them to run multiple applications simultaneously.

• It would be inefficient to save all that processing capability for just a single user.

• It ensures they process data consistently within a set deadline for a task.

• They wouldn't use a multi-user operating system.

What type of operating system is commonly used by robotics on a manufacturing line?

• Real-Time Operating Systems

• Single-User, Single-Task Operating Systems

• Single-User, Multi-Tasking Operating Systems

• Multi-User Operating Systems

Single-user, single-task operating systems are commonly used on smartphone devices.

• True

• False

An example of the role of the operating system in networking is that it comes installed with anti-virus software.

• True

• False

A small accountancy firm has recently expanded by hiring new staff. They have decided to ensure each member of staff has access to a laptop that can connect to the company network. They are concerned about the security of this though. What features of an operating system will help the company with this?

• Traceroute will identify hackers trying to access the network and block them.

• Device drivers will stop unauthorised users from connecting to the network with their own devices.

• User authentication will stop unauthorised users from logging into the laptops & accessing the network.

• Virtual memory will monitor users activity and prevent anything they shouldn't be doing.

What type of operating system is this accountancy firm likely using on these laptops?

• Real-Time Operating Systems

• Single-User, Single-Task Operating Systems

• Single-User, Multi-Tasking Operating Systems

• Multi-User Operating Systems

Most operating systems come with TCP/IP built in. What feature of an operating system does this relate to?

• Networking

• Security

• Memory Management

• Device Drivers
