What are the phases of computer virus life cycle?
The phases of a computer virus life cycle typically include: infection, replication, activation, and spread. During the infection phase, the virus gains entry into a system. In the replication phase, the virus creates copies of itself to spread further. Activation occurs when the virus is triggered to execute its malicious payload. Finally, the virus spreads by infecting other systems through various means.
What are the two phases of virus activity?
The two phases of virus activity are the infection and the attack phases. The infection phase is when the virus decides to start spreading. The attack phase is when the virus starts causing damage to your computer.
What is the lifecycle of a computer virus?
A computer virus typically starts with the infection phase, where it enters a system. It then replicates itself to spread to other systems, followed by the activation phase when it executes its malicious payload. Finally, the virus may enter a dormancy phase where it remains undetected or gets removed by antivirus software.
When does a cell copy its DNA?
The chromosomes are replicated so they are able to be split into daughter cells through the cell cycle.
DNA is replicated at this time of the cell cycle?
DNA is replicated during the S phase of the cell cycle. This phase is when the cell synthesizes a copy of its DNA to prepare for cell division.
Different phases of life cycle of a computer virus?
->Dormant phase->Propagation phase->Triggering phase->Execution phase—Dormant Phase àThis virus is idle one and activated by some event such as a file.—Propagation Phas:Virus places an identical copy of itself—Triggering Phase :Virus is activated to perform the functions—Execution Phase :Virus is performed!

When virus enter a lysogenic phase it mean?
When a virus enters the lysogenic phase, it integrates its genetic material into the host's DNA and remains dormant. The virus replicates along with the host cell during cell division. This phase allows the virus to evade detection by the immune system and can later switch to the lytic phase to produce new viruses.
What are the two phases of virus activity?
The two phases of virus activity are the infection and the attack phases. The infection phase is when the virus decides to start spreading. The attack phase is when the virus starts causing damage to your computer.
How does a computer virus work in general?
Generally, a computer virus attacks a file/program, and then injects a bunch of complex direction codes that make the program a zombie. So the virus basically kills and then mutates the code of a program, either making that infected program another copy of the virus that attacked it, or a powerhouse factory that automatically makes copies of the virus, which means that the program now is like a mass production factory making copy after copy after copy of the virus.
What stage is it when a virus enters a host cell?
The virus enters the host cell in the penetration phase.
The phase in which there is a duplication of genetic material is?
The phase in which there is a duplication of genetic material is called the S phase of the cell cycle. During this phase, the DNA in the cell is replicated, ensuring that each daughter cell receives an identical copy of the genetic material.
What is the lifecycle of a computer virus?
A computer virus typically starts with the infection phase, where it enters a system. It then replicates itself to spread to other systems, followed by the activation phase when it executes its malicious payload. Finally, the virus may enter a dormancy phase where it remains undetected or gets removed by antivirus software.
Can a computer virus copy itself from a computer to a usb drive?
Some of them can. It depends on the virus and the replication method.
During what phase are many copies of a virus made and released?
lytic
What is the stage where a cell makes a copy of its chromosmes?
It takes place in inter phase. It is the S phase
What causes virus?
A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user.
