Identity theft is a major issue as hackers become more sophisticated in their techniques. There are now so many open ports on your computer and internet router that you don’t know about. These ports are open door hackers on the web. In the past, there was no way someone could use these ports to access your system, but as hackers find new ways to send an action to trigger a reaction from your computer, which is to send personal data back to the hacker, keeping your system protected is harder than ever before.

For encrypting a file or other information stored in a computer means to convert it into a secret code and that it can’t be used or understood until it is decoded or decrypted. you might want to encrypt the files that contained a secret formula for a new invention, or some financial plans that your competitors would love to know about them in advance. When you encrypt something then the computer ask you to create a password. After that, no one will be able know about the information unless they have the same password. Encryption hides your data from unauthorized third party users . This is the process of encoding data which prevent the data from viewing or modifying by the unauthorized person.
Data Link Layer has number of specific functions to carryout. These functions include:-
- Providing a well defined service interface to the Network Layer.
- Determining how the bits of the Physical Layer are grouped into frames.
- Dealing with transmission errors.
- Regulating the flow of frames so that slow receiver are not overcome by a fast sender. [Read more…]
This protocol also provides for one directional flow of data from sender to receiver. The communication channel is once again assumed to be error-free, as in protocol Unrestricted Simplex Protocol. However, in this case the receive has only a finite buffer capacity and a finite processing speed, so the protocol must explicitly prevent the sender from flooding the receiver with data faster than it can be handled.

It is the simplest though unrealistic protocol with the nick name “UTOPIA“. In this case data is transmitted in one direction only. Both the transmitting and receiving Network Layer are always ready and the proceeding time can be ignored. An infinite buffer space is available and also communication between a Data Link Layer never damages or looses frames. [Read more…]
The design issues deals with how to make sure all frames are eventually delivered to the Network Layer at the destination and in the proper order. The usual way to ensure reliable delivery is to provide the sender with some feedback about whatever happening at the other end of the line. Typically the protocol calls of the receiver to send back special control frames bearing positive and negative acknowledgments about the incoming frames. If the sender receives a positive acknowledgment about a frame, it knows the frame has arrived safely. On the other hand, a negative acknowledgment means that something has gone wrong and the frame must be transmitted again. [Read more…]
A network contains a large number of computers and various intermediate devices. All these devices and computers must be joined so as to transfer data from one computer of network to any other computer. This can be possible by using two methods:-
The first method is to create an individual wire link from every computer to every other computer (like fully connected topology) this method requires a lot of wiring and will increase the system cost and efficiency. The other method is to use a technique of switching. In a switched network, special devices called switches, are used to join two or more computers and intermediate devices with each other. Switches can create temporary connection between two devices attached to the switch. These devices are hardware devices that may have a software component in them. When a particular virtual path is to be set, the switch is set accordingly, to create a path between two nodes. [Read more…]
