Answer: True: Worms replicate without the need for a host file. By their design, worms are supposed to self-propagate, often in environments with limited computing resources. They will use whatever services they’re capable of to do that. Stuxnet is a famous example of a worm.
A computer worm is a self-replicating computer program. It uses a network to send copies of itself to other nodes, mainly without any user intervention. Unlike a virus, it does not need to attach itself to an existing program. Worms consume bandwidth, whereas viruses almost always corrupt or devour files on a targeted computer.
