Difference between the communication and transmission.Transmission is a physical movement of information and concern issues like bit polarity, synchronisation, clock etc.Communication means the meaning full exchange of information between two communication media.
Signals are usually transmitted over some transmission media that are broadly classified in to two categories.Guided Media:These are those that provide a conduit from one device to another that include
Latest Answer : 1) Guided media: Coax, Twisted-pair, Fibre etc2) Unguided media: Wireless ...
In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.
Latest Answer : Broadband refers to signaling method which includes a relatively wide range of frequencies butBaseband refers to only one type signaling method using a relatively medium's full bandwidth. ...
BUS topology:In this each computer is directly connected to primary network cable in a single line.Advantages:Inexpensive, easy to install, simple to understand, easy to extend.STAR topology:In this all
Latest Answer : There are five topologies for networks 1. Ring Topology 2. Star Topology. 3. Bus Topology. 4. Mess Topology. 5. Hybrid Topology.Now a days we are using EXTENDED STAR topology. It is fast & reliable topology. ...
Repeater:Also called a regenerator, it is an electronic device that operates only at physical layer. It receives the signal in the network before it becomes weak, regenerates the original bit pattern
Latest Answer : Different type of networking / internetworking devicesRepeater:Also called a regenerator, it is an electronic device that operates only at physical layer. It receives the signal in the network before it becomes weak, regenerates the original bit pattern ...
A gateway operates at the upper levels of the OSI model and translates information between two completely different network architectures or data formats.
Latest Answer : I Beg to differ.According to me A device that determine the optimal path along which network traffic should be forwarded. Routers allow different networks to communicate with each other. They forward packets from one network to another based on network ...
The address for a device as it is identified at the Media Access Control (MAC) layer in the network architecture. MAC address is usually stored in ROM on the network adapter card and is unique.
Latest Answer : Short for Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) ...
Difference between bit rate and baud rate.Bit rate is the number of bits transmitted during one second whereas baud rate refers to the number of signal units per second that are required to represent those bits.baud rate = bit rate / N where N is no-of-bits represented by each signal shift.
It is a project started by IEEE to set standards that enable intercommunication between equipment from a variety of manufacturers. It is a way for specifying functions of the physical layer, the data link
The data unit created at the application layer is called a message, at the transport layer the data unit created is called either a segment or an user datagram, at the network layer the data unit created
Latest Answer : data unit in application layer is called data or message.data unit in transport layer is called segment.data unit in network layer is called packet.data unit in data link layer is called frame.data unit in physical layer is ...
