It is a generic term for section of a large networks usually separated by a bridge or router. |
It is a simple protocol used to exchange information between the routers. |
It is a very simple protocol used for transmission of IP datagrams across a serial line. |
It one of two sublayers of the data link layer of OSI reference model, as defined by the IEEE 802 standard.
This sublayer is responsible for maintaining the link between
computers when they are sending data across the physical network connection. |
IP addresses are divided into five classes as below.
Class A: 0.0.0.0 - 126.255.255.255(Can work with a network of very large hosts.)
Class B: 128.0.0.0 - 191.255.255.255(Can work in medium sized networks)
Class C: 192.0.0.0 - 223.255.255.255(Used in small LANs)
Class D: 224.0.0.0 - 239.255.255.255(Used for multicasting)
Class E: 240.0.0.0 - 254.255.255.255(Reserved for experimental purpose) |
Every line has an upper limit and a lower limit on the frequency of signals it can carry. This limited range is called the bandwidth. |
It is 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. |
|
It is a method for providing fault tolerance by using multiple hard disk drives. |
A communications protocol used to connect computers to remote networking services including Internet service providers. |
OSI(Open System Interconnection) is a network communication standard developed by ISO. |
OSI model has 7 layers such as,
7.Application
6.Presentation
5.Session
4.Transport
3.Network
2.Datalink

Network communication standards are certain rules and specifications framed by standard organisations for manufacturing network hardware and developing network software.
Major communication standards have been formed by the organisations like ISO, IEEE etc. |
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. |
The process that allows a network to self-repair networks problems is called Beaconing.
The stations on the network notify the other stations on the ring when they are not receiving the transmissions. Beaconing is used in Token ring and FDDI(Fibre Distributed Data Interface) networks. |
Attenuation is the degeneration or weakening of a signal over distance on a network cable. To avoid attenuation amplifiers or repeaters and short cables are used. |
