VLAN

VLAN stands for Virtual Local Area Network, and it is created from one or more local area networks. A Virtual Local Area Network (VLAN) is a customized network made up of one or more LANs. It allows a set of devices from different networks to be converted into a single logical network. As a result, a virtual LAN that is managed similarly to a physical LAN emerges.

Encrypting with TDEA and a single key is pointless, because it is equivalent to encrypting with the original "single" DES, which is no longer considered strong enough to resist feasible attacks. In your own words (do not quote in any way from any source), briefly explain why decrypting with TDEA and a single key was a useful operation when TDEA was developed.
