Errors are common in digital signals because of noise in the transmission line. Due to this, the data sent by the sender will change and… Read More
The minimum size of an Ethernet frame is 64 bytes. The Ethernet protocol is responsible for Network Interface Card (NIC) to Network Interface Card (NIC)… Read More
The Data-link layer is the second layer from the bottom in the OSI (Open System Interconnection) network architecture model. It is responsible for the node-to-node… Read More
Network topology is the systematic arrangement of the elements (links, nodes, etc.) of a communication network. Network topology can be used to make understand that… Read More
Prerequisite – Types of Network Topology Mesh Topology : In mesh, all the computers are interconnected to every other during a network. Each computer not… Read More
Star Topology A star may be a topology for a Local Area Network (LAN) during which all nodes are individually connected to a central connection… Read More
Bus Topology: Alternatively mentioned as line topology, bus topology could even be a specific quiet topology during which each computer and network device is connected… Read More
Hybrid Topology: Firstly before going to the topic, we saw that topology may be a connection of varied links and nodes, communicating with one another… Read More
Ring Topology may be a network configuration where device connections create a circular data path. In this each device is connected to with its exactly… Read More
Prerequisite – Services provided by Data Link Layer Logical Link Control (LLC) is one of the uppermost layers of the IEEE 802 Protocol Reference Model.… Read More
Line Discipline is function of Data link layer. It simply determines and identifies the direction of communication. It is simply process of coordinating half-duplex transmission… Read More
Data-link layer uses the techniques of error control simply to ensure and confirm that all the data frames or packets, i.e. bit streams of data,… Read More
Flow control is design issue at Data Link Layer. It is a technique that generally observes the proper flow of data from sender to receiver.… Read More
Prerequisite – Error Detection in Computer Networks  Checksum is the error detection method used by upper layer protocols and is considered to be more reliable… Read More
Point-to-Point Protocol (PPP) is basically a Wide Area Network (WAN) protocol that performs or works at layer 2 by simply encapsulating frames for transmission or… Read More
