to secure analog data is called scrambling in data communication
Encryption
In digital communication we talk about signal while in data communication we talk about data and the could be in the form of packets or frames.

Encryption
Scrambling codes are unique sequences used in communication systems, particularly in CDMA (Code Division Multiple Access) networks, to differentiate between multiple users accessing the same frequency channel. They help to spread the signal across a wider bandwidth and mitigate interference by effectively randomizing the data before transmission. This ensures that the receiver can accurately decode the intended signal while filtering out noise and other users' signals. Scrambling codes enhance system capacity and improve the overall quality of communication.
spreading codes make all data streams have the same chip rate, (3.84Mcps) and scrambling codes distinguishes between users. usage differences spreading - return link = separation of physical data and controls channels. forward ink = separation of downlink connections to different users in same cell. scrambling - return link = separation of terminals forward link = separation of sectors code family spreading = OVSF scrambling = Gold code and extended (S2) spreading spreading = yes, increase transmission bandwidth scrambling = No, does not affect transmission bandwidth.
The scope of work and the educational requirements are the difference between data communication and data communication information.
data communication link
They are both forms of communication They are both a form of communication; data communication is a subset of telecommunication, telecommunication send data between two links by means of electromagnetic. (Like satellite), while data communication means send data by telecommunication, it consists of codes of 0's and 1's. In computer means, Data communication is digital data and telecommunication is equipped to send digital data to receiver.

What is the difference between data communication and telecommunication ?
Networking security is used to protect a series of computers connected to a specific network by scrambling the data passed between the network. This renders the data useless outside the network and secure.
