Inter connection between the two or more computers is called the networking. Using three types of network are Intranet, Internet and Extranet (Eg. LAN, WAN & MAN)
Q:What is Bandwidth?
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. Every line has a capacity of transmission of data, The maximum amount of data that can be transferred in a single line is called Bandwidth.
Q:What is VLAN?
VLAN Stand for Virtual Local Area Network. It is a logical grouping of network users and resources connected to administratively defined ports on a switch.
Uses of VLAN are as follows:-
1. It is securied connection.
2. It increases flexibility.
3. It creates separate broadcast domain.
Q:What is CIDR?
CIDR Stands for classless inter domain routing. It helps in preventing the wasting of IP address and nowadays we are facing the shortage of the IP address.So this CIDR helps to prevent the waste of IP address.Shortly IPV6 will come into exist.
Q:What is VLSM?
VLSM stands for Variable length subnet mask, when try to separate a major subnet into minor ones, then that process is called VLSM. We can subnet in various lengths.
Eg: 22.214.171.124-/24 can be separated into 126.96.36.199-/30 and 188.8.131.52-/28
Q:What is unicast?
Unicast is one type of transmission in which information is sent from one host to another host (i.e Source to Destination). In another words, Unicast transmission is between one-to-one nodes
Unicast ---> A transmission to a single interface card.
Q:What is Multicast?
Multicast is such differ from Unicast. It is another type of transmission or communication in which there may be more than host and the information sent is meant for a set of host.(i.e one source to group of destination
Multicast ---> A transmission to a group of interface cards on the network.
Q:What is Broadcast?
Broadcast is one type of transmission in which information is transfer from just one host but is received by all the host connected to the network. (i.e one source to all destination)
Broadcast ---> A transmission to all interface cards on the network.
