Question

what is a virus explain its working mechanism​

Answer 1

Answer:

A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea

When some disease-causing viruses enter host cells, they start making new copies of themselves very quickly, often outpacing the immune system’s production of protective antibodies. Rapid virus production can result in cell death and spread of the virus to nearby cells.

Explanation:

Answer 2

A computer virus, much like a flu virus, is designed to spread from host to host and has the ability to replicate itself. Similarly, in the same way that flu viruses cannot reproduce without a host cell, computer viruses cannot reproduce and spread without programming such as a file or document.
