Computer networking and its different types

Computer networking is the practice of connecting multiple devices to share resources and communicate with each other. It involves the use of various hardware and software components to facilitate data transmission and exchange between computers, servers, routers, switches, and other network devices.At its core, computer networking enables the sharing of information, files, and resources such as printers and internet connections among interconnected devices. This connectivity allows users to collaborate, access remote resources, and communicate in real-time, whether within a local area network (LAN), wide area network (WAN), or the internet.The foundation of computer networking lies in the establishment of protocols and standards that govern how data is transmitted and received across the network. Protocols such as TCP/IP (Transmission Control Protocol/Internet Protocol) define rules for addressing, routing, and error detection to ensure reliable and efficient communication between devices.Networking hardware plays a crucial role in facilitating connectivity and data transmission within a network. Devices such as routers, switches, hubs, and access points serve as the infrastructure that enables devices to connect and communicate with each other. Routers, for example, manage data traffic between different networks, while switches facilitate communication within a single network by directing data packets to their intended destinations.In addition to hardware components, networking relies heavily on software solutions to manage and control network operations. Network operating systems (NOS) provide the necessary software infrastructure for configuring and managing network devices, implementing security measures, and monitoring network performance. Examples of popular NOS include Cisco IOS, Juniper Junos, and Microsoft Windows Server.Security is a critical aspect of computer networking, given the potential risks associated with unauthorized access, data breaches, and cyberattacks. Network security measures such as firewalls, encryption, virtual private networks (VPNs), and intrusion detection systems (IDS) help safeguard network resources and sensitive information from malicious threats.Computer networking encompasses a wide range of technologies and methodologies, including wired and wireless networking, cloud computing, virtualization, and software-defined networking (SDN). Wired networking utilizes physical cables such as Ethernet or fiber optic cables to establish connections between devices, while wireless networking relies on radio waves to transmit data over the air.Cloud computing and virtualization technologies have revolutionized the way networks are deployed and managed, allowing organizations to leverage shared resources and scale their infrastructure dynamically. Software-defined networking (SDN) is another emerging paradigm that centralizes network control and management through software-based controllers, enabling greater flexibility,

There are four main types of computer networks: personal area networks (PANs), local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). PANs connect devices within 10 meters of an individual, LANs connect computers in a small area like a building using technologies like cables, MANs interconnect multiple LANs to cover a larger geographic region using telephone lines, and WANs extend over large areas like states or countries using technologies such as telephone lines, fiber optics, or satellites. The largest WAN is the internet.Computer Network Types.pptx

A computer network can be categorized based on its size as PAN, LAN, MAN, or WAN. A PAN covers an area of about 30 feet and connects personal devices like laptops and phones. A LAN connects computers within a building using cables, providing faster data transfer and higher security than larger networks. A MAN interconnects multiple LANs within a city using telephone lines to connect organizations like businesses, schools, and governments. A WAN spans large geographic areas like countries and states, with the internet being the largest example, connecting networks globally.COMPUTER NETWORKs.pptx

A computer network connects computing devices like phones and servers to transmit and share information. There are different types of networks based on geographical scale: local area networks (LAN) within a building; personal area networks (PAN) within 10 meters of a person; metropolitan area networks (MAN) connecting LANs across a city; and wide area networks (WAN) extending across large areas like states or countries. The Internet is one of the largest WANs used globally for business, education, and communication between organizations.Computer Network Types.pptx

A computer network connects multiple computers together allowing them to share resources like internet access, printers, and file servers. There are 5 categories of computer networks:
1) Local Area Network (LAN) - connects computers in a small area like a building using cables or wireless technology.
2) Personal Area Network (PAN) - connects personal devices within 10 meters of an individual.
3) Metropolitan Area Network (MAN) - connects multiple LANs in a larger region like a city using telephone lines.
4) Wide Area Network (WAN) - extends over large geographic areas like countries using telephone lines, fiber optic cables, or satellites.
5) The internet is one example of a large WAN.Classification of computer networks
