Before delving into the network layer, we must have some basic understanding of the network.
i.e. what is the network, types of the network, IP addresses, DHCP, Host, Router, basics idea networkingcommunication protocol (TCP/IP, UDP).
What is network?
Network is a tool or infrastructure which provides help to communicate between the systems.
Types of the network
LAN (Local Area Network) or subnet
WAN (Wide Area network)
MAN (Metropilotan Area Network)
IP Address: Ip address is a logical address, configured by the DHCP or manual is an address which can be recognized by the network to communicate.
DHCP (Dynamic Host configuration protocol): DHCP is a hardware module which configure the IP address for system without any conflicts between the system IP addresses.
HOST: Host is system (i.e. Computer, Laptop, Mobile, Router) which is connected to the network.
Router: It is a device which helps to communicate between one network to another network.
TCP/IP (Transmission Control Protocol) and UDP (Universal Datagram Protocol): TCP/IP or UDP is network layer or transport layer protocol which define how data will be transferred between one host to another host.
Before diving into the theory of network layers, it would be beneficial to familiarize our self with the basics of network.It involves various components and concepts, including:
Nodes/Hosts: These are devices that are connected to a network. They can include computers, servers, printers, routers, and switches .
Links: These are the physical or logical connections between nodes. They can be wired or wireless .
Protocols: These are sets of rules and standards that govern how data is transmitted over a network. Examples of protocols include TCP/IP, HTTP, and FTP
LAN: is a network that covers a small area, such as an office or a home. LANs are typically used to connect computers and other devices within a building or a campus.
WAN: is a network that covers a large geographic area, such as a city, country, or even the entire world. WANs are used to connect LANs together and are typically used for long-distance communication.
Before diving into the theory of network layers, the initial suggestion is to get a knowledge about how a simple network works and basic concepts of networking and there types.
Also know about the ROUTER,HOST and INTERNET and how they all are connected with each other.
The initial suggestion to dive into some new concept is to understand and apply few basic questions(why, what and when) to the concept. Similarly here, we need to understand what is a network, why it is required and when it has to be used. Besides getting idea about the Network, we also need to understand few basic concepts of network like host/node, hub, switch, router, packets, internet, PAN, LAN, WAN, MAN and a basic image view of a network.
Before diving into the network layer we first need a proper understanding of what is network and how network works .First we need of basic understanding of network ,network devices and network protocols with that we can say we have grashp the basic understanding of network and we are elegible to dive into the network layers.
Before diving into the theory of network layers ,the initial stage is to get the knowledge of basic network , types and protocols .It includes routers, host, LAN and internet.
