SSL and TLS, which stand for Secure Sockets Layer and Transport Layer Security, respectively, provide a secure protocol that enables networked peers to engage in encrypted communication with one another. The most typical use for SSL is the transfer of confidential information between a web browser and a web server.
What happens when data is transmitted?
When data is exchanged between two or more digital devices, it is done so in the form of bits. Serial transmission and parallel transmission are the two ways that data can be sent from one digital device to another. Parallel transmission is the more common approach. The sending of data bits one after the other across a single channel is what constitutes serial data transmission.

- authentication using OSPF.
- SNMPv3.
Give an example of data transmission.
Transmission of data can take place both externally and internally to a device, in addition to the external communication option. One example of a kind of data transmission is the random access memory (RAM) or hard drive that transfers information to a processor.
What are the three ways that data is transmitted?
There are three categories for the many types of data transfers via LANs: unicast, multicast, and broadcast. One single packet is delivered to one or more nodes via each of the several types of transmission. A single data packet is carried across a network in the course of a unicast transmission, which begins at the source and ends at the destination.
What benefit does data security provide?
Data security ensures that all of this information is kept in the exact location that it should be in. Important for maintaining your good name: Any business that is able to protect secrets helps to develop confidence among all stakeholders, including consumers, who are aware that their data is safe and secure while dealing with that firm.
What about data security is accurate?
The protection of programs and data in computers and communication systems against unauthorized access, modification, destruction, disclosure, or transfer, whether accidental or intentional, by building physical arrangements and software checks is referred to as data security. This protection can prevent unauthorized access, modification, destruction, disclosure, or transfer.
Who founded computer security?

What does data transmission mean?
The movement of information from one digital device to another is what is known as data transmission. This exchange takes place across data streams or channels that are point-to-point in nature. Now channels could have been implemented in the past using copper cables, but these days they are almost certainly going to be part of a wireless network.
What various forms of data transmission are there?
There are three different ways that information may be sent, and they are referred to as simplex, half-duplex, and full-duplex respectively. Between any two linked devices, the direction in which a signal travels can be determined by the transmission mode.
What device is used to transmit data?
A modem is utilized by digital computers in order to convert the digital electronic data that is being transmitted, and an analogous device is utilized at the receiving end in order to convert the incoming signal back to the digital electronic data that was transmitted.
