This service enables its users to expand their Local Area Networks. In this section, we will discuss the different types of network. Internet is the technology that is used to connect different computer systems located in different geographic location.
Computer – Networking Advertisements. LANs are composed of inexpensive networking and routing equipment. Wireless and USB based. Networking technology has revolutionized the world and created a new arena for the overall development of every nation. The physical connection between networked computing neyworks is established using either cable media or wireless media.
Internet enables its users to share and access enormous amount negworks information worldwide. However, in nefworks connectivity, some other devices can also be attached such as laser printers, fax machine, etc. When a user requests a page using some web browser located on some Web Server anywhere in the world, the Web Server responds with the proper HTML page.
A router is a type of device which acts as the central com;uter among computers and other devices that are a part of the network.
With the help of networking, the communication system has now become highly efficient, frugal, and fast. Before you start proceeding with this tutorial, I’m making an assumption that you are already aware about basic computer concepts like what is keyboard, mouse, monitor, input, output, primary memory and secondary memory etc. It mostly operates on private IP addresses and does not involve heavy routing.
Wide Area Network or simply WAN is a system computee network that covers a large tuttorialspoint area across the world. The communication delay is very low. Computers automatically detect USB card and can install the drivers required to support the USB network card automatically. Number of systems connected in LAN may vary from as least as two to as much as 16 million.
Metropolitan Area Network or simply MAN is a system of network that normally covers a large metropolitan area city part. External network cards are of two types: A computer network spanned inside a building and operated under single administrative system is generally termed as Local Area Network LAN. Wireless network card needs to be inserted into the motherboard, however no netwrks cable is required to connect to the network.
It ultimately helps to control, secure, and manage the important data. LAN uses either Ethernet or Token-ring technology. The best-known computer network is the Internet.
Local Area Network or simply LAN is the technique of interconnecting a few computers located in a given premise. Tutorialspkint is the largest network in existence on this planet. The resources such as printers, file servers, scanners, and internet are easily sharable among computers.
What is a Computer Network
Because of shortage of address spaces, it is gradually migrating from IPv4 to IPv6. The most commonly used cable is Category 5 cable RJ Metro Ethernet is a service which is provided by ISPs. Because of having computer networking, a person sitting in the United States of America provides technical support to a person sitting in a remote part of India.
Basics of Computer Science – Networking Advertisements. Since they are equipped with very high speed backbone, WANs use very expensive network equipment.
Computer – Networking
Motherboard has a slot for internal network card where it is to be inserted. If you are not well aware of these concepts then I will suggest to go through our short tutorial on Computer Fundamentals. Ethernet is most widely employed LAN technology and uses Star topology, while Token-ring is rarely seen. Through the networking system, it is easy to share and install the software from one computer system to another computer system. Generally, networks are distinguished based on their geographical span.
The network also provides the facility to access databases located remotely. It is equipped with holes called ports. The services of WAN are provided by public government agencies as well as private agencies.
DCN Computer Network Types
For example, MAN can help an organization to connect all of its offices in a city. Through the networking system, it is very simple to decentralize the data processing system.
LAN provides a useful way of sharing the resources between end users. Create files and store them in one computer, access those files from the other computer s connected over the network. At huge level, internet works on Client-Server model. To inter-connect various continents, fibers are laid under sea known to us as submarine communication cable. A computer can be connected to another one via a serial port but if we need to connect many computers to produce a network, this serial connection will not work.
After completing this tutorial you will find yourself at a moderate level of expertise in Data Communication and Computer Networking from where you can take yourself to next levels.
Most branded computers have network card pre-installed. Internal and External Network Cards.
