Bacteria vs Virus
Speaking in technological terms, a virus is a program that makes your computers malfunction, steasl data and/or destroys it. Computer virus function by hiding in other programs and spread through the Internet or exchangeable data devices like floppy and pen drives. Computer virus has a possibility of spreading whenever two or more computers are linked even if that is without Internet access through a local area network. There is no term like bacteria in technological terms!

In biological terms, virus and bacteria are differentiated on the basis of size, reproductive methods and resistance to different kinds of medical interventions. Bacteria are living organisms with only a single cell and include ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) – which are defined as genetic codes. A virus includes several other mechanisms other than these two types of acids along with a protein shell. Bacteria are several times larger than virus.

On the basis of their different methods of reproduction, bacteria can be considered independent units that are self-reproducing. Virus on the other hand split the DNA and RNA genetic material into two. Bacteria are therefore easily able to survive all kinds of enviroments and flourish easily.

A virus necessarily requires a living host to reproduce. A virus enjoys longevity of the dormant kind and can survive for thousand of years before finding a suitable host to reproduce in. A virus latches on to cells and penetrates them in the host. The virus imposes its own replicating genetic code on to that of the cells in the host body.

Most bacteria are considered either harmless or beneficial to human being and they break down organic matter to destroy harmful parasites. Very few bactereia are considered harful for human beings. All virus are extremely harmful to humans. Antibiotics easily kill bacteria. Virus cannot be destroyed so easily. Bacteria are also considered living creatures while virus is not.
