Definition of Information Transmission

Information transmission is the passing on or publishing of information to someone or a group of people in order to get the right responses. Some information when passed on or given requires a feedback while some do not require feedback. For example, information that the principal wants to meet with all JSS 1 students by 12 noon will make the students to go to his office. However, information that reminds students to be in their classes after break period does not mean that the students should go to the principal’s office.

Methods of Transmission of Information

  1. Ancient methods: This is the method of communication in the olden days without electronic medium.
  2. Modern methods: This is the method of communication in the modern days with electronic devices.

Modes of Information Transmission

Information is transmitted in two modes, namely:
1. Synchronous Transmission: This is a process where data is transferred in regular interval that are timed by clocking signal allowing for a constant and reliable transmission for time sensitive data such as real time video or voice. Examples are video conferencing

  1. Asynchronous Transmission: This is like the opposite of synchronous, meaning that signal timing is not required.
