How to decode Tag-Length-Value Quickly

Basically, in TLV, the format is Tag, Length, and Value. In the list of protocols, TLV is one of the types. Transmitting the data depends on the protocol you used. However, many financial transactions still follow the TLV format. According to IBM, TLV data is three parts. The tag tells what type of data it is. The length field has a length of the value. The Value field has actual value.

Structure of TLV.TLV comprises three field values.  TagLengthValueEMV formulated different tags. They have their own meanings. Usually, the Tag and Length together takes 1 to 4 bytes.
The Best example for TLV.In the below example, you can find the sample TAG, LENGTH, and VALUE fields.

[Tag][Value Length][Value] (ex. "9F4005F000F0A001")

Tag Name = 9F40

Value Length (in bytes) = 05 
Value (Hex representation of bytes. Example, "F0" – 1-byte) = F000F0A001

In the above message, tag 9F40 has some meaning designed by EMV company. Here you can find a list of EMV Tags.

Computers science Vs Information science to read now real differences

Computer science and information science are both confusing terms among many students and professionals. This post tells you clearly the real differences between these two sciences.
1# Computer ScienceComputer scientists are, in fact, scientists. They are focused with the theory of computational applications. That means they understand the “why” behind computer programs. Using algorithms and advanced mathematics, computer scientists invent new ways to manipulate and transfer information. Computer scientists are generally concerned with software, operating systems and implementation. Like Neo in The Matrix, computer scientists can see and make sense of code. Computer science students will learn the fundamentals of different programming languages, linear and discrete mathematics, and software design and development. Computer scientists study the machine itself and understand how and why various computer processes operate the way they do.Related: Computer Science degree do you really ne…
