What You Will Learn in

This Computer Network-Data Link Layer Online Test helps you to Boost your Knowledge in Computer Network. In this test, we will cover the topics in the form of questions.
The data link layer is the important layer of OSI model. Data link layer has two sublayers LLC (logical link control) and MAC(Media access control).
The data link layer is the main part of IEEE-802 and according to that, the work of LLC is to control data flow among various application and services. Working of MAC according to IEEE-802 is to control the physical media for transport.
There are two common MAC layer types includes ETHERNET and 802.11 Wireless specifications.

There are some functions of the data link layer -
(1). It handles the problem which occurs during the bit transmission error.
(2). It ensures data flows at a pace that doesn't overwhelm sending and receiving devices.
(3). It permits the data to layer 3 that is Network Layer where data is addressed and routed.
