What is a secure data transmission?
In computer science, secure transmission refers to the transfer of data, such as sensitive or proprietary information, over a secure channel. Many secure transmission methods require some type of encryption. The most common type of email encryption is called PKI. An exchange of keys takes place in order to open an encrypted file.
What technical ways are used to ensure the secure data transmission Class 10?
Answer. Answer: Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), provide secure communications over the Internet, including Web browsing, e-mail, Internet faxing, instant messaging, and other data transfers. It is an encryption protocol that provides secure communications over the Internet for web browsing, email, Internet fax, instant messaging, and other data transfers.
Which technique is used for secure data transmission?
The methods used for this purpose are steganography and encryption. Encryption scrambles information but reveals its existence. Steganography hides the existence of confidential information.
What is the importance of secure data transmission?
The importance of data encryption to protect transmission over open networks. Secure protocols such as HTTPS are often used to provide additional security functions to ensure integrity and encryption. Cyber breaches threaten organizations more than ever.
What are the methods of data transmission?
There are two methods used to transmit data between digital devices: serial transmission and parallel transmission. Serial data transmission sends data bits one after another on a single channel. Parallel data transmission sends multiple data bits simultaneously on multiple channels.
Which mechanism will make sure that data transmission is secure Mcq?
Description: Hyper Text Transfer Protocol Secure (HTTPS) is a security protocol that maintains security as data is transmitted from the browser to the server and vice versa.
What is data security and its importance?
Data security is the practice of protecting digital information from unauthorized access, corruption, or theft throughout its life cycle.
What are the 3 methods used to transmit data?
LAN data transmissions fall into three categories: unicast, multicast, and broadcast. In each type of transmission, a single packet is sent to one or more nodes. In unicast transmission, a single packet is sent from a source to a destination on the network.
What is transmission and its types?
There are two types of transmission media: guided and unguided. Guided transmission media are cables such as twisted pair cable, coaxial cable, and fiber optic cable. Guided transmission media are wireless, such as infrared, radio, and microwave.

Which of the following options are security methods used to prevent?
The following options are security methods used to prevent unauthorized users from accessing sensitive information Encryption is also a secret used to reverse the process, turning meaningful data into what appears to be nonsense. Decryption is a reversal of the process.
How is encryption done?
Encryption uses complex mathematical algorithms and digital keys to encrypt data. The encryption algorithm (cipher) and encryption key encode the data into ciphertext. When the ciphertext is sent to the recipient, the same or a different key (cipher) is used to decode the ciphertext to its original value.
Which drive is safe in PC?
On Windows computers, most of the files you are working on are stored on the C: drive, which is the default drive. To save to a different drive (such as a flash drive), you must know the drive letter and specify that drive letter when saving the file.
