In the bus, all nodes are connected with another in a loop while instar they are connected to a central node. . SMTP is a connection oriented protocol. SMTP is a connection oriented protocol. It defines seven layers or levels in a complete communication system. Frame Relay devices fall into the following two general categories: -The size of an ATM cell is 53 bytes, 5 byte header and 48 byte . It is most popular because it hits a good balance among cost, speed & easy installation. AN WirelineWireless & Mobile Access. (c) To detect errors. Each cell is 53 bytes long - 5 bytes header and 48 bytes payload. It explains IP addressing and network addressing such as IP address, subnet mask, IP address types and IP classes in detail. FDDI (Fiber Distributed Data Interface) is a set of ANSI and ISO standards for data transmission on fiber optic lines in a local area network (LAN) that can extend in range up to 200 km (124 miles). A computer network is a set of devices connected through links. A hybrid five-layer reference model resembling the popular TCP/IP model will be discussed. Now you see for yourself how easy it is to remember www . TCP/IP is transmission control protocol and internet protocol. By Dinesh Thakur. Lec.no: 1. Typically, there are six building blocks: the hub, bridge, router, brouter, the LAN/MAN/WAN switch, and the transport media. E-mail stands for electronic mail. 7. The recommendations of the 802.11 committee have become the standard for wireless networking. Any computer can talk to any other computer Net 2 Net 1 Net 3 Net 4. SMDS is designed for moderate bandwidth connections . Because of these pros, Ethernet in computer networks will give support to all popular network protocols. A computer network is a set of devices connected through links. Explanation: Double duplex is not a legitimate channel for transmission in computer network. A Demilitarized Zone (DMZ) is a network segment that is separated from other networks. Domain Name System is also called DNS. It encodes data into small fixed - size cells so that they are suitable for TDM and transmits them over a physical medium. A computer network is mainly of four types LAN(Local Area Network) PAN(Personal Area . Numerous varieties of terminal equipment are connected to the ATM network access node, which interconnects to the ATM hub and other . Channelization is basically a method that provides the multiple-access and in this, the available bandwidth of the link is shared in time, frequency, or through the code in between the different stations.
