Distinguish between symmetric-key and asymmetric-key cryptosystems. - ANSWER - Aysmmetric key cryptography utilizes two separate keys, a public and a private key, as opposed to symmetric key cryptography, which only utilizes one key. While encryption and decryption in symmetric key cryptography is based on substitutions and permutations of symbols, encryption in asymmetric key cryptography is based off of applying mathematical functions to numbers. Distinguish between public and private keys...

First users were the engineers who built and programmed computers, then employees who had received specialized training were users, and now today, anyone and everyone can be a user. - Evolution of Users Sends files over the network at the request of clients. Responds over LAN, within one location/site.
