IT PROVIDES DATA TO SUPPORT STUDENT COUNSELLING
it is primary data
The difference between primary data and secondary data is that primary data is the information from the original research.
Primary data is is data that has been observed or collected first hand
Primary data is very advantageous over secondary data in several types of ways. First of all, it is the actual thing, or the whole thing, depending on what primary data you are talking about. Primary data in the form of architecture is obviously much preferable over secondary data such as pictures, because it is there in front of you, and can be examined by your senses, not only seen by your eyes. Obviously secondary data also has advantages, such as being easier to obtain than primary data, but primary data is still a good way to obtain information.
Primary functions provided by Layer 2 data encapsulation include data link layer addressing, and the detection of errors via cyclic redundancy check calculations. An additional function is delimiting groups of bits into frames.
* addressing * error detection * frame delimiting
a) Identifies pieces of data as part of the same communication b) Ensures that data pieces can be directed to the correct receiving end devices

No, accessor member functions are a sign of good class design, particularly in terms of data encapsulation.
No, frame delimiting is a primary responsibility of the Logical Link Control sublayer of the Data Link Layer.. Data link layer exists of 2 sublayers; Media Acces control Sublayer (MAC) & Logical Link Control sublayer (LLC)
The router encapsulates the packet in the appropriate data link frame type for the outgoing data link. The router determines the exit interface after data encapsulation.
to transmit data
Not quite. Encapsulation means to combine data and the methods that work upon that data into a single unit (an object), such that access to both the data and methods is restricted in a controlled manner. Data-hiding is fundamental to encapsulation.
ODBMS stands for object oriented database management system. Encapsulation in ODBMS can be defined as binding of data together.

the four basic functions of the microcomputer are input, output, processing, and storage of data.
