LLC vs MAC Sublayers
hello friends this is Vasu Birla and today we will know about sublayers of data link layer .
As we discussed in the last part that data link layer takes data from physical layer in form of bits (0,1) and check the transmission errors and then convert it in to frames.
Data Link layer performs very important and complex task in our network. so for reducing of its complexcity it further divided in two parts or sub-layers. These are -
Logical Link Control Layer - This sublayer provides services to Network Layer and hides details of data link layer on network layer. It establish and control Logical links between local devices on network. Today Most LAN technologies use this LLC protocol.
Media Access Control Layer- For Reducing the data traffic and conflict problem in network medium this MAC layer is used. MAC layer defines that how devices communicate on network mediums .
In the next paRT we will know about Layer 3 or network layer ,,, ok hare krishna,,, good day ..
