Abc logistics company is expanding it is a banking industry I need to know the elements of the communication process

Could you be a bit more specific in what your looking for to be explained? What you've asked for is a hugely broad topic.

The basic elements of communication however, in a medium independent setting are:

1. The actual Message
2. The person who wishes to communicate something
3. The person you want to get the message to.
4. The encoding process, typing, writing, recording voice etc
5. The decoding process, reading, listening etc
6. The medium being used, face-to-face, email, letter etc
