What is Internet?
The
internet is a type of world-wide computer network. Internet is a “network of
networks”. Internet is consisted of academic, business and government networks,
which carry various information and services. It is global communication
accessed through the web. Internet deals with protocols and standards.
Example: E-mail,
Web access and services, file transfer
Protocols:

Syntax: Syntax means format of data or the structure how it is pretend.
For example, first eight bits for sender address, next eight bits for receiver address, rest of the bits for message/information.
Semantics:
Semantics is the meaning of each section of bits e.g. The address bit means the
route of transmission or final destination of the message.
Timing: Timing
means, at what time data can be sent and how fast data can be sent or received.
Standards:
Standards provide guidelines to the manufacturers, vendors, government agencies and service provider. It ensures that interconnectivity and compatibility of the device. Standards help in maintaining market competitiveness and guarantees interoperability. Data communication standards are of two categories: De facto and De Jure.

means by facts or by convention. The standards that are not approved by any
organization but are widely used are De facto standards. These are established
by manufacturers.
De jure: De jure

The article provides a basic introduction to networks by explaining the idea of interconnected people or things through familiar examples such as social media, railway tracks, highways, and branch offices connected to a head office. It then extends this concept to computer networks, where two or more computer systems are connected to communicate and share information.
DeleteThe explanation provides a useful starting point for students who want to understand networking concepts through practical examples. These fundamentals can be applied while developing Networking Projects for Final Year, where understanding how systems communicate and exchange information can help connect theoretical concepts with practical applications.
The distinction between a general network and a computer network also creates a foundation for exploring areas such as intranets and the Internet. Students interested in extending these concepts into security-focused applications can explore Network Security Projects for Final Year, where networking principles can be applied to practical security scenarios.

ReplyDeleteA network is a collection of interconnected devices, such as computers, servers, smartphones, and printers, that communicate and share data with each other through wired or wireless connections. Networks enable users to exchange information, access shared resources, and communicate efficiently across different locations.
ReplyDeleteComputer networks play a vital role in modern communication and business operations. Examples include Local Area Networks (LANs) within offices or schools, Wide Area Networks (WANs) that connect geographically distant locations, and the Internet, which is the world's largest network.IT Domains. Networks improve collaboration, resource sharing, and access to information, making them essential for both personal and professional use.
