Today everyone is surrounded by a computer and the networks that is created by a computer or any other electronic devices. Our life cannot complete without the use of these devices. In our daily life we use a different types of devices such as personal computers, Mobile phones and other connecting devices. Now we cannot move outside. We try to play with our devices such as gaming consoles and other gaming devices.  Now most of people profession is coming under this network. You must be aware of all the terms and definitions related to this networking field. More and more people are going to join this field every day.

The main motive of this article is to discuss all the important terms that are related to this Networking field. It will make your work easier and easier.

1. What is meaning of word Packets?   

Here packets are also known as a data packet. In simple words it is very simple to a real world packet but difference is that it comes under the field of computers. We all know packet is simply a unit or a piece. It is a collection of a Digital data that is collectively known as a Packets. This packet is formed so that it can be easily transferred from one side to the other side over a network.   Packet data are divided into two parts so that it can easily recognize and reach their destination without any disturbance.

1. Type of the information that is related to this transformation.
2. Type of control that is associated with this data. The control that is associated with the data is of deaf different type.

Some of the control associated with data packet is as follows:

1. The address of the place of destination.
2. The source address of the data.
3. There is a handler such as error checking. It checks error during their transfer of data from Source to destination.
4. It also contains the information about the type of data and its size. If at any place it found bigger then it will be broken into smaller units for faster transfer of data over the network.  So these are the quality of a good packet that contain all the detail information about packets. So that destination can easily accept it and do work as demanded.

2. What is a Meaning of a LAN?

The full form of LAN is well known as Local Area Network whereas Full Form of WAN is as Wide Area Network. There are some of the difference between the Local Area Network and Wide Area Network. By the name of Local Area Network it indicates that it is a type of network that is set up in a small area of a particular location. It is used to connect as many devices but restricted to that location. This type of connection is established using a wire known as an Ethernet Wire. All the devices or user in that location is well connected to this wire or simply using a Wireless protocol. As this technology is used to connect all users of a particular location so user can have a faster connectivity over that Local Area Network. The data transfer rate is extremely high as compared to a Wide Area Network. This type of LAN connection is famous in a place where 10-20 PC need to connect using an Ethernet connection. Some of the places such as Office, Group of people belong to same occupation.  This kind of network is also known as a Private network. This can be used privately by one group. 

3. What is a meaning of a WAN?

Wide Area Network is a establish over a different location. Many people connect with this kind of network. It is used to connect large devices from different location and provide access the internet over this network.  This network is made so that it can easily connect the users from various locations over this network. In many cities this technique is used to provide connect to the users. To develop a Wide Area Network a large number of idea is used. It is really difficult to develop this type of Network.  In other word the internet that we used is a part of this big platform. This Platform is known as a wide area network. The idea of Private WAN is also introduced. This can be used by a group of companies with branches that is spread all around the city or even country. This Private Network gives them way to transfer their important data from one location to another. Bank network is one among such kind of Network.

4. What is the meaning of Ethernet?

This term is very famous in the field of internet. This type of internet is mostly used by a home user as well as in a workplace. This term mostly say about the type of wire that is used in a Network. This technology is used to provide a connect to our connecting devices so that it can connect to other connecting devices within a specified network. This can be used as a Local Area Network as well as Wide Area Network. This protocol is Recomended by IEEE and this type of network is better suited for our IT industry. The full form of the IEEE is the Institute of Electrical and Electronic Engineers. The Ethernet wire is made up of copper coaxial wire that is made to give a high speed internet that is about 10 mb\Second.This is really fast. To get such speed Ethernet wire must be an original.  These days data transfer rate is extremely fast because of the development of new standards that can transfer data with a speed of 100 mb\second.This is even more in some cases.   To gain so much speed a special Ethernet wire is developed that is a combination of a Twisted copper pair and a fiber optic.

5. What IS the meaning of the VPN.

The full form of the term VPN is Virtual Private Network. This word is a combination of various technologies. It uses the concept of an Ethernet virtual Private network. There is  one point that is associated with these technologies that it is  able to provide a secure connection to their different users from one computer to another. Users from different network can communicate with the help of this technology. It allows them to do so. Their connection is always secure. No one can indicate their communication.  This technology uses a very secure way to transfer data from one end to another end. It uses an idea of encrypt so that no one indicate the type of data is transferred from one end to another. The data packet that is included in that packet. It simply uses the idea of encrypting only to the core data and use a an idea of encapsulated to the data that is located outside of the packet. The outside of the packet includes the address of the destination place where is packet is to intend.

When this packet reached its destination place then at that time it can fire from encryption and a user at the destination can easily view that core data. This VPN is a great tool and a device for a person from offices. They can Securely transfer their data from one place to another without any fear. This VPN increases their work efficiency and reduce a large amount of burden from their head. It saves time and money.
