There are several easy steps to take for ensuring data leakage protection. Firewalls, antivirus programs, and intrusion detection systems are all great steps to begin the process.
A firewall can avoid data leakage.
Data leakage is the unauthorized transfer of data from a computer or datacenter to the outside world. It can occur by a number of different methods including copying data, removing tapes or disks physically, or simply remembering the data and reproducing it elsewhere.
what are the merits and demerits of data communication
to represent the frames sequence numberI believe this is wrong in the 5th edition....Network+ Guide to Networks on page57 it states that protocols in the data link layer add a header to the front of each packet and a trailer to the end of each packet to make frames. (The trailer indicates where a frame ends.)paragraph 4
For the Pentium the front side data bus is 64 bits wide. The back side is 32 bits wide.

Data Link
1)Time taken to error correcting is less than doing detection and retransmission. Bandwidth use will be less. 2) In detection and retransmission if back messaging occurs the bandwidth will be more
Data Link Layer
collects iris, fingerprint, photograph, and biographical data
To increase productivity, communicate and collaborate data (including its changes), and to replicate data (preventing data loss). Data is not put into computers to increase security, as computers have the ability to easily leak data. You must take your own measures to prevent data leakage.
