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")
where

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.

How Does DevOps Speeds up Delivery

The DevOps is basically a Software development system and most popular in Cloud computing. On-device software and storage may not be passe just yet, but it’s getting there, as more and more computing processes are taking place in the cloud. 



Many companies are also preferring distributed computing, which allows multiple computers to network with one another to solve a task (and, unlike the cloud, gives companies control over the actual hardware involved).

Many of the skills involved with cloud computing and distributed computing are related, so the two are often grouped together:

Skills to learn include SQL for database management, programming languages like Ruby, JavaScript, and Python for building cloud-based applications, and DevOps (a software development system popular in the cloud computing field). Specific in-demand programs include Microsoft Azure and Amazon Web Services.
