Computer Networking Tutorial Pdf

all part of, computer networks let us share information and resources. In business , . The most basic computer network (which consists of just two connected. What is a Network? • A network refers to two or more connected computers that can share resources such as data, a printer, an Internet connection, applications . This book is meant as a serious and more-or-less thorough text for an introductory college or graduate course in computer networks, carefully.

You do not have to register for expensive classes and travel from one part of town to another to take classes. All you need to do is download the course and open the PDF file. This specific program is classified in the Network category where you can find some other similar courses. Thanks to people like you?

You will find your happiness without trouble!

Data encapsulation is the process of breaking down information into smaller manageable chunks before it is transmitted across the network.

It is also in this process that the source and destination addresses are attached into the headers, along with parity checks. It shows how devices and cables are physically laid out, as well as how they connect to one another. VPN means Virtual Private Network, a technology that allows a secure tunnel to be created across a network such as the Internet.

For example, VPNs allow you to establish a secure dial-up connection to a remote server. This is a protocol that provides a way for multiple computers on a common network to share single connection to the Internet. The Network layer is responsible for data routing, packet switching and control of network congestion. Routers operate under this layer.

Network topology dictates what media you must use to interconnect devices. It also serves as basis on what materials, connector and terminations that is applicable for the setup. RIP, short for Routing Information Protocol is used by routers to send data from one network to another. It efficiently manages routing data by broadcasting its routing table to all other routers within the network.

It determines the network distance in units of hops. There are several ways to do this. Install reliable and updated anti-virus program on all computers. Make sure firewalls are setup and configured properly. User authentication will also help a lot. All of these combined would make a highly secured network.

This is a peripheral card that is attached to a PC in order to connect to a network. It is an interconnection of computers and devices that are geographically dispersed. It connects networks that are located in different regions and countries. The physical layer does the conversion from data bits to electrical signal, and vice versa.

This is where network devices and cable types are considered and setup. Proxy servers primarily prevent external users who identifying the IP addresses of an internal network.

Without knowledge of the correct IP address, even the physical location of the network cannot be identified. Proxy servers can make a network virtually invisible to external users. This layer provides the protocols and means for two devices on the network to communicate with each other by holding a session. This includes setting up the session, managing information exchange during the session, and tear-down process upon termination of the session.

Are there limitations? A fault tolerance system ensures continuous data availability. This is done by eliminating a single point of failure. However, this type of system would not be able to protect data in some cases, such as in accidental deletions.

The 10 refers to the data transfer rate, in this case is 10Mbps. The word Base refers to base band, as oppose to broad band. T means twisted pair, which is the cable used for that network. Private IP addresses are assigned for use on intranets. These addresses are used for internal networks and are not routable on external public networks.

These ensures that no conflicts are present among internal networks while at the same time the same range of private IP addresses are reusable for multiple intranets since they do not "see" each other. NOS, or Network Operating System, is specialized software whose main task is to provide network connectivity to a computer in order for it to be able to communicate with other computers and connected devices.

DoS, or Denial-of-Service attack, is an attempt to prevent users from being able to access the internet or any other network services. Such attacks may come in different forms and are done by a group of perpetuators. One common method of doing this is to overload the system server so it cannot anymore process legitimate traffic and will be forced to reset.

It is made up of 7 layers, with each layer defining a particular aspect on how network devices connect and communicate with one another.

One layer may deal with the physical media used, while another layer dictates how data is actually transmitted across the network. The main purpose of this is to prevent crosstalk. Crosstalks are electromagnetic interferences or noise that can affect data being transmitted across cables.

By using address translation instead of routing, address sharing provides an inherent security benefit. That's because host PCs on the Internet can only see the public IP address of the external interface on the computer that provides address translation and not the private IP addresses on the internal network. It is also known as physical address or Ethernet address.

A MAC address is made up of 6-byte parts. If the first octet begins with a 0 bit, that address is Class A. If it begins with bits 10 then that address is a Class B address. If it begins with , then it's a Class C network. This limitation can be overcome by using repeaters and switches. Data encapsulation is the process of breaking down information into smaller manageable chunks before it is transmitted across the network.

It is also in this process that the source and destination addresses are attached into the headers, along with parity checks. It shows how devices and cables are physically laid out, as well as how they connect to one another.
