The types of topologies are:. Network reliability plays a significant role in the network functionality. The network monitoring systems and devices are the essential requirements for making the network reliable.
The network monitoring system identifies the problems that are occurred in the network while the network devices ensure that data should reach the appropriate destination. Every signal has a limit of upper range frequency and lower range frequency. The range of limit of network between its upper and lower frequency is called bandwidth. A network is a connection setup of two or more computers directly connected by some physical mediums like optical fiber or coaxial cable.
This physical medium of connection is known as a link, and the computers that it is connected are known as nodes. A node that is connected to two or more networks is commonly known as a gateway. It is also known as a router. It is used to forward messages from one network to another. Both the gateway and router regulate the traffic in the network. A router sends the data between two similar networks while gateway sends the data between two dissimilar networks.
Once the domain name is entered, then the domain name system will translate the domain name into the IP address which can be easily interpreted by the computer. Using the IP address, the computer can locate the web page requested by the user. It is used to specify data transfer rate. In 10Base-T, 10 specify the data transfer rate, i. The word Base specifies the baseband as opposed to broadband.
T specifies the type of the cable which is a twisted pair. POP is responsible for accessing the mail service on a client machine. POP3 works on two models such as Delete mode and Keep mode. It is a unique address means no two devices can have same MAC addresses. There are three ranges of IP addresses that have been reserved for IP addresses. They are not valid for use on the internet. If you want to access internet on these private IPs, you must have to use proxy server or NAT server.
A public IP address is an address taken by the Internet Service Provider which facilitates you to communication on the internet. This feature is generally found in Microsoft operating system. Anonymous FTP is used to grant users access to files in public servers. Users which are allowed access to data in these servers do not need to identify themselves, but instead log in as an anonymous guest.
A protocol is a set of rules which is used to govern all the aspects of information communication. First is directly used by the users and the second supports application programs.
The Domain Name System is the second type supporting program that is used by other programs such as to find the IP address of an e-mail recipient. A link is connectivity between two devices which includes the cables and protocols used in order to make communication between devices.
These seven layers can be grouped into three categories:. The OSI physical layer is used to convert data bits into electrical signals and vice versa.
On this layer, network devices and cable types are considered and setup. OSI session layer provides the protocols and means for two devices on the network to communicate with each other by holding a session. This layer is responsible for setting up the session, managing information exchange during the session, and tear-down process upon termination of the session. It is a set of protocol layers that is designed for exchanging data on different types of networks.
You can ping devices using its IP address or name. Sneakernet is the earliest form of networking where the data is physically transported using removable media. A switch receives packets faster than the shared link. It can accommodate and stores in its memory, for an extended period of time, then the switch will eventually run out of buffer space, and some packets will have to be dropped.
This state is called a congested state. In Networking, multiplexing is the set of techniques that is used to allow the simultaneous transmission of multiple signals across a single data link. Address sharing provides security benefit instead of routing. This article is useful for those who are attending the interview on Networking.

It includes the type of cables and protocols used for one device to be able to communicate with the other. A backbone network is a centralized infrastructure that is designed to distribute different routes and data to various networks. It also handles the management of bandwidth and multiple channels.
A Tell me something about yourself. Tell about your eductaion, place you belong to, some struggle in life which shows that you have positive attitude and will to fight the odds.
