What is computer virus?

Computers and Technology
1 answer:
Ainat [17]4 years ago
3 0

It is a (software) program that is installed on a computer without the user's knowledge for the purpose of making harmful changes. A computer virus attaches itself to another program (the execution of the host program triggers the action of the virus). And most of them perform actions that are malicious in nature, such as destroying data. A computer virus operates in two ways: As soon as it lands on a new computer, begins to replicate or it plays dead until the trigger kick starts the malicious code. The term 'computer virus' was formally defined by Fred Cohen in 1983.

Which branch of study can help Jessica study the concept of light
Fiesta28 [93]

Answer:

Physics, Quantum Mechanics

Explanation:

Light is a stream of photons with no weight. If you want to dig deeper in this mysterious phenomena, you should study physics and quantum mechanics. Physics takes up things like the theory of relativity, which can be useful in studying spacetime and how light travels through it, and quantum mechanics, being the study of matter in an atomic level, should help you get an understanding on how photons of light travel and why they behave so strangely.
