Eduqas CS - 3.6 - 7-Layer OSI Model Quiz

What are networking standards?

• A type of hardware used in networking

• A programming language for network design

• A method to physically connect devices

• Rules that allow computer systems to communicate across networks

Why is a network design split into layers?

• To make it easier to modify and use

• To increase the number of devices in a network

• To reduce the cost of network hardware

• To eliminate the need for protocols

Which layer of the OSI model allows humans and software applications to use the network?
