Packet Switched service transfers the data from source to destination. Data is transferred on a type of network in which small units of data called packets are transferred. Each packet contains a destination address within it, where it has to be received.This type of communication between receiver & sender is ... Read More

In a packet switching network, the data or information is transmitted between the sender and receiver in the form of packets. It does not require a dedicated physical path to transmit the fixed-size packet across the sun-network.If the size of information is large, then it is subdivided into multiple packets. ... Read More

When too many packets are present in the network it causes packet delay and loss of packet which degrades the performance of the system. This situation is called congestion.The network layer and transport layer share the responsibility for handling congestions. One of the most effective ways to control congestion is ... Read More

We need a virtual-circuit subnet for connection-oriented service. Virtual circuits were designed to avoid having to choose a new route for every packet sent.Instead, a route from the source machine to the destination machine is chosen as part of the connection setup and stored in tables inside the routers, when ... Read More

When connectionless service is offered, packets are frequently called Datagrams (just like telegrams) because individual packets are injected to the subnet and are routed individually.No advance setup is required. Subnets are called Datagram subnets. When Connection oriented service is provided, then before any packet is sent a path from source ... Read More

Let us understand what a Wi-Fi Direct mode is.Wi-Fi Direct ModeThe Wi-Fi Direct is built upon the same Wi-Fi technology used by most modern consumer electronic devices to communicate with wireless routers. It allows two devices to communicate with each other, provided that at least one of them is compliant ... Read More

802.11 architecture uses two types of modes, which are as follows −Infrastructure ModeThe most popular mode used to connect clients like laptops and smartphones to another network such as company intranet or internet.This mode is shown below −In infrastructure mode every client is associated with an Access point which is ...

Ethernet is a way of connecting computers together in LAN, it is the most widely used method of linking computers together in LANs. The basic idea of its design is that multiple computers have access to it and can send data at any time.Token Ring is also a computer networking ... Read More

Ethernet was developed at Xerox PARC between 1973 and 1974. Engineer Bob Metcalfe invented it for interconnecting advanced computer workstations, making it possible to send data to one another and to high-speed laser printers.It was originally intended to create a network in a small area known as a Local Area ...

Protocols in which stations listen for a carrier and act accordingly are called Carrier Sense Protocols. Multiple Access tells the fact that multiple nodes send and receive on the medium.Transmissions of one node are received by all other nodes using the medium. Carrier Sense Multiple Access (CSMA) is a probabilistic ... Read More
