This gives the address of the next instruction on a process.

There are five (5) necessary conditions that can cause deadlock to occur.

Mutual Exclusion is where at least one process must be in a non-sharable mode.

No preemption means that a process can only release the CPU non-voluntarily.

All the following are benefits of virtual memory except?

All the following are ways we can secure files except?

A device that allows for the transmission of data over cables lines.

A switch is much preferred over hub.

A switch broadcast to all the computers attached while a hub makes a direct connection with the attached computer.

Which of the following represents the correct ordering of the connectivity devices used in a network.

Which of the following represents the 5th layer in the OSI model?

Which layer of the OSI model are switches used?

MAC addressing is used at this layer?

This layer is responsible for routing packets and uses various protocols in the process.

The Presentation layer of the OSI model is responsible for encrypting and compressing the data.

This topology allows for all devices to be connected to a central hub

A disadvantage of this topology is that a break anywhere in the cable shuts the network down.

An advantage of this transmission media is that it is not susceptible to interference.

A disadvantage of this transmission media is that it is limited physically.
