ACL - Access Control List

ACL stands for Access Control List, which is a mechanism used in computer networks to control access to network resources based on predetermined rules. It is commonly employed in routers, switches, firewalls, and other network devices.

DNS - Domain Name System

DNS is a hierarchical decentralized naming system that translates domain names into IP addresses and serves as the basic component of the Internet system.

It helps users access websites and resources with easy domain names instead of with complicated IP addresses. 

FTP - File Transfer Protocol

FTP is a network protocol that is used for transferring files between a client and a server, such as the Internet. FTP is where the client initiates a connection to the server to perform file transfer operations.

2. Cryptography Acronyms

Cryptography Acronyms involve various protocols and algorithms that are used for secure communication and authentication of information.

These acronyms explain many techniques that can be used to ensure safe transmission and transactions over the internet and enable the protection of data from any modifications. Some of the Cryptography acronyms are as follows:

AES - Advanced Encryption Standard

AES is a symmetric encryption algorithm used to protect sensitive data be it on the internet or any system. It is a standard cryptographic algorithm for securing communications and data storage.

RSA - Rivest-Shamir-Adleman

RSA is another widely used asymmetric encryption algorithm in cryptography. It is named so after the inventors who introduced the algorithm and it is based on a complex mathematical formula used for encryption and decryption of data to safeguard it. 

SHA - Secure Hash Algorithm

Another cryptography acronym is the SHA algorithm which is a popular cryptographic hash function used to generate hashes from data messages for security applications.

There are a number of algorithms that come under SHA that include SHA-1, SHA-256, and so on.
