The official book website is In its broadest sense, a network consists of two or more entities, or objects, sharing resources and information. Although this book is about computer networks. PDF Drive is your search engine for PDF files. Basics of Computer Networking Thomas G. Robertazzi Stony Brook University September 19,

Basic Home Networking Course for Beginners Computer networks consist of many different components, technologies and protocols working together. Getting Started In order for two computers to talk to each other they need: To be Connected cable or Wireless this is known as the connection media. To have a common language. To have An Address. Connecting Computers Together Early computer networks used cable to connect computers together in a wired network.

You can use free books to brush up on networking basics or even learn more about advanced networking concepts. This is a great idea if you're entering into the networking world for the first time or are needing a refresher before a new job or school assignment.

The 4 Best Free Computer Networking Books

However, relatively few quality free books exist that cover general computer networking topics. Follow the links below to download and read the best free computer networking books online. Some of these free networking books download in a format that requires a special program or app to read it.

If you need to convert one of these books to a new document format that works with a specific computer program or mobile app, use a free document file converter. There are 24 chapters in this book that are separated into three parts: Author Eugene Blanchard completed this book based on his experience with the Linux operating system.

The topics covered in this book are generally applicable across environments: OSI model, area networks, modems, and wired and wireless connections. This page book broken up into 63 chapters should satisfy the basic needs of anyone looking to get familiar with a wide range of network technologies.

The address is also often called the physical address and the Ethernet address. It is shown as 6 hexadecimal numbers separated by colons e.

Notice windows using a dash — as a delimiter. Note 1: On modern network cards it is possible for MAC addresses to be manually assigned, but it is not normal to do so. In addition 64 bit MAC addresses are now used. Links and Networks Ethernet is a data link protocol.

It is possible for computers to talk to each other using just Ethernet, and with no networking protocol, but it is not practical You can liken a link to a street. Streets have houses and houses have numbers. An Ethernet link the street has computers houses which in turn have numbers Ethernet, Mac Address or Physical Address.

However you can have many streets and the streets are connected. Routers divide out Ethernet links into networks. The Networking protocol also has addresses IP address , and these addresses are not fixed but assigned by a network administrator or automatically using a service called DHCP Dynamic host Configuration protocol. Ethernet Broadcasts, Broadcast Domains and Collisions To send a message to all computers on an Ethernet network a broadcast address Mac Address of all ones is used.

See Understanding binary numbers The broadcast domain is the effective range of the broadcast, which can be limited by inserting level 3 IP level network devices e. A broadcast will be re-transmitted by hubs, switches, bridges level 2 and repeaters level 1. Note: Levels are the levels in the 7 layer OSI data model. Network devices Bridges and switches working at level 2 data link layer can create separate collision domains. Even though bridges and switches divide a network into separate collision domains, the computers are still part of the same broadcast domain.

This is shown in the diagram below. However a broadcast will be seen by devices on both sides of the switch. Bridges vs Switches Bridges and switches do very similar functions and today you can only download switches. Bridges were used to join network segments i.

Hubs vs Switches Hubs operate at the physical level, and were once the primary mechanism for connecting computers together. Hubs do not create a separate collision domain they just repeat packets. They have been replaced by switches. If you look on site for a hub it will be a switch.

The term frame is used for data units at the data link level and the the term packet for data units and the networking level. Hence we have Ethernet frames and IP packets. The data frame contains data and frame management information.

The concept used to describe data frames is that of a letter and envelope. The letter is the data which is placed inside an envelope that contains the addressing information. This concept of data being inserted into an envelope is used repeatedly in data communications, and it is an important one to grasp. The envelope containing the data letter can simply be inserted into another envelope and so on.

Although the Ethernet protocol alone is sufficient to get data between two nodes on an Ethernet network, it is not used on its own.

Computer Networking : Principles, Protocols and Practice

Ethernet represents what is known as a data link protocol, and for networking we need a networking protocol which in our case is IP internet protocol. It is however the IP protocol which contains the important IP addresses, which are used for connecting computers together across the Internet, and in local networks.

The diagram below illustrates how data is placed inside protocol envelopes headers. At the receiving end it is unpacked in the reverse order. The IP address is the most important address as far as we are concerned, as it is a logical address, meaning it is assigned by us, and can be changed.
