Answers
sql distinct clause produces a list of only those values that are different from one another is correct.
Only distinct (different) values can be returned using the SELECT DISTINCT statement. A column in a table frequently has numerous duplicate values, and occasionally you only want to list the unique value. As a database constraint, the UNIQUE keyword in SQL makes sure that no duplicate values are stored in a given column or set of columns. The SELECT statement, on the other hand, uses the DISTINCT keyword to retrieve distinct rows from a table. In addition to the select keyword, the distinct keyword is also used. When it is necessary to prevent duplicate values from existing in a particular column or table, it is useful. A one-column table containing the results is returned by the Distinct function, which applies a formula to every record in a table.

Answers
A mathematical structure known as an invertible matrix is a block cipher utilize in order to change plaintext characters into two or more encrypted characters.
What is Block Cipher?
A block cipher is a method of encrypting data in blocks to generate ciphertext with the help of a cryptographic key and algorithm. In contrast to a stream cipher, which encrypts data one bit at a time, a block cipher processes fixed-size blocks at the same time. The majority of modern block ciphers are built to encrypt data in fixed-size blocks of 64 or 128 bits.
A block cipher encrypts and decrypts a block of data using a symmetric key and algorithm. A block cipher requires an initialization vector (IV), which is added to the input plaintext to increase the cipher's keyspace and make brute force attacks more difficult. The IV is generated by a random number generator and combined with the text in the first block and the key to ensure that all subsequent blocks produce ciphertext that differs from the first encryption block.

The protocols used to control communication between web browsers and web servers are HTTP and HTTPS, which open the appropriate resource when a link is clicked. When requesting content from a web server, HTTP utilizes TCP port 80 while HTTP uses TCP port 443 instead. With the help of numerous security tools, HTTPS, a secure variant of HTTP, keeps communications between a web browser and a server private.
Control messages are sent to hosts and network devices using the Internet Control Message Protocol (ICMP). Network devices such as routers and others keep an eye on the network's performance. These devices can use ICMP to transmit a message when an error occurs.
