Information in this article focuses on wireless networking and computer networks, which are related to, but different than, social networking. Computer networks can be categorized in several different ways. One approach defines the type of network according to the geographic area it spans. Local area networks LANsfor example, typically span a single home, school, or small office building, whereas wide area networks WANsreach across cities, states, or even across the world.

The internet is the world's largest public WAN. Computer networks also differ in their design approach. The two basic forms of network design are called client-server and peer-to-peer. Client-server networks feature centralized server computers that store email, web pages, files, and applications accessed by client computers and other client devices.

On a peer-to-peer network, conversely, all devices tend to support the same functions. Client-server networks are common in business and peer-to-peer networks are common in homes.

In bus networks, for example, all computers share and communicate across one common conduit, whereas in a star network, data flows through one centralized device. Common types of network topologies include bus, star, ring, and mesh.

Communication languages used by computer devices are called network protocols.

Another way to classify computer networks is by the set of protocols they support. Networks often implement multiple protocols and each network supports specific applications.

Network operating systems and other software applications generate network traffic and enable users to do useful things. While other types of networks are built and maintained by engineers, home networks belong to homeowners who often have little or no technical background.

Various manufacturers produce broadband router hardware designed to simplify home network setup. Home networks have increased in capability with each generation of new technology. Years ago, people commonly set up a home network to connect a few PCs, share documents, and perhaps share a printer. Now it's common for households to network game consoles, digital video recorders, and smartphones for streaming sound and video. Home automation systems have also existed for many years, but these have grown in popularity recently with practical systems that control lights, digital thermostats, and appliances.

Small and home office SOHO environments use technology that is similar to home networks. Businesses often have additional communication, data storage, and security requirements that require expanding networks in different ways, particularly as the business gets larger.

Companies with buildings in multiple locations utilize wide-area networking to connect these branch offices together. Though also available and used by some households, voice over IP communication, network storage, and backup technologies are prevalent in businesses.

Larger companies also maintain internal web sites, called intranets, to help with employee business communication. Public web sites, peer-to-peer P2P file sharing systems, and various other services run on internet servers across the world.The network is two or more connected computer which can share resource like a printer, an internet connection, application, etc. It is a collection of computer systems and devices which are linked together using a wireless network or via communication devices and transmission media.

The network provides connectivity between computers and devices within a restricted range where only one entity is controlled or authorized to manage the entire system.

In this tutorial, you will learn What is a Network? What is the Internet? Types of Networks: Why do you need a Network? Why do you need Internet? The internet is a collection of interconnected devices which are spread across the globe. It is a network of networks that consist of public, private, public, sales, finance, academic, business and government networks. The internet is a type of network and called network of networks. A WAN spans across a large geographic area, such as a state, province or country.

Why do you need a Network? You don't need to load all the software on every computer. Instead, load in the primary server and use on every computer connected to the network.

Easy connectivity and fast communication Internet Access Sharing Helps you in performance enhancement and load balancing Why do you need Internet? The network provides connectivity between computers and devices within a restricted range.

In this system, only one entity is controlled or authorized to manage the entire system. The Internet is a network of computers at different locations around the world. Allows you to send an email message from every location Helps you to send or receive files between different computers Using the Internet, you can participate in discussion groups, such as mailing lists and newsgroups.

It allows all small, medium and large size businesses to sell their products with less investments.It is important to lay a foundation before you build a general-purpose computer network. You forgot to provide an Email Address.

It explores the requirements that different applications and communities place on the network, introduces network architecture basics and options, discusses the networking and IT groups that should be consulted in network design, examines key elements in computer networks and identifies the key metrics used to evaluate the computer network performance. Peterson and Bruce S.

Davie Morgan Kaufmann, A network must provide connectivity among a set of computers. While some networks limit the number of connected machines, others grow as large as a global wide area network WAN. Efficiency is the key requirement of computer networks, which is why networks use packet switching as their main strategy.

It's too simplistic to view a computer network as simply delivering packets among a collection of computers, however. A network should be thought of as the way to deliver a set of applications distributed over those computers.

Success includes both understanding the applications' requirements and recognizing the limitations of the underlying technology. The challenge is to fill the gap between what the application needs and what the technology can provide. Networks do not remain fixed and must be able to evolve to accommodate technological changes, and networking and IT professionals must be able to manage them.

Designing a network to meet those requirements isn't easy. The most basic requirements for a network are that they must provide general, cost-effective, fair and robust connectivity among a large number of computers. Network architectures are general blueprints that guide the design and implementation of your network.

The idea of abstraction, which hides your networking details behind a well-defined interface. The idea of abstraction is to make a model that can capture an important aspect of the system, but the challenge is to identify abstractions that simultaneously provide a service that proves useful in a large number of situations. Abstractions naturally lead to layering.

internet and networking pdf

The idea is that you start with the services the underlying hardware offers, then add a sequence of layers, each of which provides a higher level of service. Layering helps IT professionals build a network into more manageable components. One of the things that has made the Internet such a success is the fact that software running in general-purpose computers provides so much of its functionality, which means new functionality can be added easily.

As a result, new applications and services can deployed in a heartbeat. Knowing how to deploy network software is an essential part of understanding computer networks. Specific instructions and visual representations for both the client and the server can be found in the networking PDF. Naturally, computer networks are expected to perform well, and it's vital to understand the factors that can impact network performance.

A network's bandwidth is the number of bits that can be transmitted over the network in a certain period of time. Latency is how long it takes a message to travel from one end of a network to the other and is measured in time.Internetworking is the process or technique of connecting different networks by using intermediary devices such as routers or gateway devices.

Internetworking ensures data communication among networks owned and operated by different entities using a common data communication and the Internet Routing Protocol.

Internetworking is only possible when the all the connected networks use the same protocol stack or communication methodologies. A computer network is a set of different computers connected together using networking devices such as switches and hubs. When a network communicates with another network having the same or compatible communication procedures, it is known as Internetworking. Internetworking is also implemented using internetworking devices such as routers. These are physical hardware devices which have the ability to connect different networks and ensure error free data communication.

They are the core devices enabling internetworking and are the backbone behind the Internet. Toggle navigation Menu. Home Dictionary Tags Networking.

The network you have at home uses the same networking technologies, protocols and services that are used in large corporate networks and on the Internet. A home network will have between 1 and 20 devices and a corporate network will have many thousands.

Setting Up and building a Home Network will introduce some basic networking component and show you how to build a home network and connect it to the Internet. Networks can be wired or wireless with most networks being a mixture of both. Wired networks use Ethernet as the data link protocol.

Wireless networks use Wi-fi as the data link protocol. However other wireless options are being developed for the IOT Internet of things. There are many different ways network nodes can be connected together.

Common connection technologies like Wi-Fi, Bluetooth etc are designed to work using a particular network topology. When designing networks and choosing connection protocols having an understanding of these topologies is important. Each of these topologies has advantages and disadvantages this Network topologies article has a really good overview of each topology along with advantages and disadvantages. How the nodes on a network communicate with each other can be very different to how they are physically interconnected.

Common logical typologies are Peer to Peer and Client Server. No node has any special role. This was the original networking model of windows networking. In a Client Server network a server has a special role e.

Basic Networking Concepts-Beginners Guide

This is the networking model used on the web and the Internet and on modern large Windows networks. A Modern example of Client Server networking is the Web. Facebook,Twitter,Google search and many other web services use this networking model. Ethernet and Wi-Fi are Data link protocols that are responsible for framing data on the media cable or wireless. See this Wiki for details. The levels are:. An Internet Protocol address IP address is a numerical label assigned to each device e. IPv4 uses 32 bits for addressing, however due to the rapid growth of the Internet, all IPv4 addresses have been allocated as of The roll out of IPv6 across the Internet is happening slowly, and IPv4 will be with us for many years to come especially in home and small office networks.

As IP6 rolls out they will also be a need to operate with two addresses until migration is complete, and IP4 is discontinued. IP addresses are logical addresses, and are assigned by a network administrator or can be auto assigned using DHCP.

See Internal and external IP addresses for more details.

Difference between Network and Internet

Most modern networks use automatic IP address assignment via DHCP with manual assignment only being done in special cases. This can cause problems see troubleshooting Internet connections.

When you type in a domain name into your web browser the name is translated into an IP address by a DNS server usually located on the Internet. I am also a beginner in networking.
