Routers operate in the Network Layer of the OSI model. The OSI model is a conceptual framework that defines how network devices and applications communicate with each other. It consists of seven layers, each responsible for a particular function. The layer that routers operate in is the network layer, which is responsible for facilitating communication…
TCP / IP TCP / IP is a protocol suite for internet usage. Two protocols are named in this protocol suite. These two protocols are: Transmission Control Protocol (TCP) and Internet Protocol (IP). TCP is used for connection-oriented reliable transmission services, and IP is used to determine the address of each host on that network.…
The main purpose of one computer communicating with another computer is to share information. Suppose two computers are located in different places and these two computers want to exchange information. Then when a computer sends the data, the data will reach the destination computer through many media. There are some rules to ensure that the…
What is Network? A network consists of two or more computers come together and exchange information this process is called Network. A minimum of two computers is required to network. Types of networks: Network Can be divided into three parts: 1. LAN 2. MAN 3. WAN Local Area Network (LAN): A network of different computers…
What Is IPsec? IPsec corresponds to Internet protocol security or IP Security. IPsec is a protocol cortege that encrypts the full IP traffic before the packets are transferred from the source node to the destination node. IPsec is also able and responsible for authenticating the individualities of the two nodes ahead the genuine communication takes…

Bandwidth Merge or Load Balance with Failover is One of the most generally utilized applications of load balancing is to supply a single Internet service from double services, such as when we take from two ISP internet line 4Mbps+4Mbps=8Mbps than it will be equal 8Mbps. If we do two ISP line merge than we will…
