Networking Standards ( Osi Layers )

WAN(Wide Area Network)-Wan is 2 or more local area networks connected together.It is fairly expensive to set up but like the LAN it is very fast.There are many different ways of creating WANS”S like using VPN’s over the internet.A WAN is created when the users of a LAN frequently needs access to rescources of another

It is in most cases used to connect multiple local area networks together to form a bigger network.

You will discover different network topologies and different types of networks: LANs, WANs, and internetworks (internets). The concept of switching is discussed to show how small networks can be combined to create larger ones. You will learn about the Internet: its early history, the birth of the Internet, and the issues related to the Internet today. This module covers standards and standards organizations.

Networking can help you gain new clients, give you new insights, discover new business connections and opportunities.

A network is the way to communicating throughout the internet; also, it is connected to the group of computers that allow to sharing the information through a network. Not only that network is just for sharing the information though connected of group computers, but for internet that including social media, game online, telecommunication, programming that would be require network for professional career, and more that can be any in the real world, even that can be also for security throughout network to protect whoever uses network for personal and business. A network is a-must

Local area network (LAN) is a wireless network that is mostly used in a work place or small building. To be able to make this work, you will need an access point connected to a switch to create the wireless network. There are different types of hardware components that are used to set a wireless network up such as network adaptors, Ethernet cables and a hub.

The internet is a worldwide system of computer networks which is sometimes called as “The Net”. It consists of several interconnected networks which provides various information and communication facilities using standardized communication protocols. Internet is also called as a network of networks, which means that it connects millions of computers together worldwide. As long as computers are connected to internet they can easily communicate with each other.

Computer networks allow for employees within an organization to share files and exchange ideas more efficiently. Also, computer networks make it easier to back up all the company’s data on an offsite server. Computer networking supports business operations and contributes immensely to globalization. Therefore, organizations invest heavily in computer networks ensuring they work efficiently. This paper discusses ten points to consider when evaluating a computer network. These evaluation points explore the network’s: security, data rate, network upgrade tolerance, device interfacing, internet connections, application performance, network services, wireless connectivity, and its cost.

Networks: wide-area network (WAN) a network that connects computers over a large geographic area, such as a state, province, or country. Local-area network (LAN) is a network that connects computers that are in close proximity to each other, such as an office building or a college campus.

The network which connecting the devices to a larger area like small towns covering area up to 50 km called metropolitan area networks. These networks are high speed networks that interconnect businesses with other businesses and the internet.

One of the most talked, known and controversial issues today is the Internet. Internet is a large network made up of a number of smaller networks. Almost every computer in an educational facility and in home and small office use is connected to some type of a network. People spent a lot of time on the Internet, which may make them seem isolated. However, the Internet does not foster isolation, because it may be used for many different things like communication, education, problem solving and etc.

A WAN (Wide Area Network) is a network that covers a geographical scale, nearly all WANS are LANs that are all connected to each other. WANs are commonly connected either through the internet or special arrangements made with phone companies or ISP’s (Internet service provider). A wide are network is different from a metropolitan area network because of the distance between each of the networks as a MAN (metropolitan area network) only covers a small area like a city unlike the WAN which covers the geographical area.

It is very easy to communicate through a network. People can communicate efficiently using a network with a group of people. They can enjoy the benefit of emails, instant texting, telephony, video conferencing, chat rooms.

A network may be defined as a number of devices interconnected by some technology which facilitates communication between the various devices on the network. Each device is called as a node. The device (Node) may be a printer, computer or any other device which can send and receive some sort of data generated by other devices on the same network.

Networking architecture is vital in the organisation of any business firm in today's globalised world. RFID, Cloud Computing, Intranet Network Architecture and Digital Rights Management (DRM) are major fields of endeavour that require the resources of companies. Increasingly, all aspects of an organisation are linked via the Internet and various other technologies in ways of connectivity that we did not even imagine before.
