Computer Network

According to Computer Network Tutorial - javatpoint, A computer network is a set of interconnected computers that are able to communicate and share data with each other. Networks can be as small as two computers connected together in a home, or as large as millions of computers connected across the globe. Networks allow computers to share resources, such as files, printers, and applications, as well as access the internet. They also allow users to communicate with each other, either through email, instant messaging, or video conferencing.

Difference between Internet and Internet

According to Intranet vs. internet: what’s the difference, and why does it matter?, Difference Between Internet and Intranet (with Comparison Chart and ... and Difference between Internet and Intranet | Find Out More - BYJUS, The main difference between the internet and an intranet is that an intranet is a closed network while the internet is a public network. In short, the internet is for all; an intranet is for a select group of people. The internet provides access to everyone, while an intranet permits only authenticated users to access it. An intranet is a private network that belongs to a firm or an institution. The internet provides unlimited information that everyone can view, while on Intranet, data circulates within the organization.

Significance of networking

The significance of networking can be seen in many areas.

1. Networking allows for the sharing of resources, such as files and printers, between computers.
2. It also allows for communication between users, such as email, instant messaging, and video conferencing.
3. Networking also allows users to access the internet, which provides an unlimited amount of information.
4. Additionally, networking allows for the sharing and streaming of audio, video, and other media files.
5. Finally, networking provides a way for people to connect with each other and collaborate on projects, such as through social media or cloud computing.

Types of network

Personal Area Network

According to Personal area network - Wikipedia and 3 Examples of a Personal Area Network - Simplicable, A personal area network (PAN) is a computer network for interconnecting electronic devices within an individual person's workspace. It is typically wireless, and provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. PANs are often used to connect personal devices, such as laptops, tablets, and smartphones, allowing them to share files and resources, such as printers and internet access. They can also be used to connect to external networks, such as the internet. Bluetooth is a common technology used for PANs, but other technologies, such as Near Field Communication (NFC) and Wi-Fi, are also used.

Local Area Network

A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building. The defining characteristics of a LAN, in contrast to a wide area network (WAN), include its higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines. A typical LAN may be composed of cabling and one or more switches that establish network segments, and shared network resources such as printers, modems, and file and application servers. A LAN in turn may also contain multiple sub-networks, each with its own subset of devices. LANs can be connected to larger networks, such as a wide area network (WAN) or the Internet. Connected LANs can be part of a corporate intranet, allowing authorized users access to company resources through the LAN.

Metropolitan Area Network

According to data from What Is Metropolitan Area Network Network And How It Works? - Tesca ..., Metropolitan Area Networks (MAN) - tutorialspoint.com, What is a metropolitan area network (MAN)? | Cloudflare and Local area network (LAN) - Study CCNA, A metropolitan area network (MAN) is a computer network that connects computers within a metropolitan area, which could be a single large city, multiple cities and towns, or any given large area with multiple buildings. A MAN is larger than a local area network (LAN) but smaller than a wide area network (WAN). It connects LANs using high-speed backbone technologies, such as fiber optics and provides up-link services to the wide-area network (WAN) and the internet. Data transfers are moderate in speed and propagation delays are moderate as well. MANs are typically used to connect corporate networks, large campuses, and other large organizations.

Wide Area Network

Based on data from How does Metropolitan Area Network work? - EDUCBA, What is a metropolitan area network (MAN)? | Cloudflare, Local Area Networks (LANs) & Wide Area Networks (WANs) and Local Area Networks (LAN) and Wide Area Networks (WAN ... - OmniSecu, A wide area network (WAN) is a computer network that covers a large geographic area, such as a city, state, country, or even the entire world. WANs usually use public or leased telecommunications lines to connect different parts of the network. WANs are typically used to connect corporate networks, and are often used for long-distance communication between different offices and locations. WANs have a much greater data transfer rate than local area networks (LANs), and can provide access to a variety of remote services, including file sharing, email, and other applications. WANs also use a variety of technologies, such as fiber optics, satellite, microwave, radio, and more.
