The result becomes a virtual LAN that is administered like a physical LAN. The full form of VLAN is defined…

What is TCP Three-Way HandShake? Three-Way HandShake or a TCP 3-way handshake is a process which is used in a TCP/IP network to make a connection between the server and client. It is a three-step process that requires both the client and server to exchange synchronization and acknowledgment packets before the real data communication process…

What is the TCP/IP Model? TCP/IP Model helps you to determine how a specific computer should be connected to the internet and how data should be transmitted between them. It helps you to create a virtual network when multiple computer networks are connected together. The purpose of TCP/IP model is to allow communication over large…

What is OSI Model? The OSI Model is a logical and conceptual model that defines network communication used by systems open to interconnection and communication with other systems. The Open System Interconnection (OSI Model) also defines a logical network and effectively describes computer packet transfer by using various layers of protocols. Characteristics of OSI Model…

What is a Computer Network? A Computer Network is a group of two or more interconnected computer systems that use common connection protocols for sharing various resources and files. You can establish a computer network connection using either cable or wireless media. Every network involves hardware and software that connects computers and tools. Different Types…

What is Topology? Network topologies describe the methods in which all the elements of a network are mapped. The topology term refers to both the physical and logical layout of a network. Types of Networking Topologies Two main types of network topologies in computer networks are 1) Physical topology 2) Logical topology Physical topology This…
