Answer: rootkit
Explanation:
Hi, A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software.
A rootkit provides continued privileged access to a computer while hiding its presence. Because of this hiding characteristic it is very difficult to detect.
Once a rootkit has been installed, it allows someone to have total remote control of a computer and do things such as files executions and system changes.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The CPU is responsible for processing instruction. CPU instruction processing goes through three stages. Fetch, Decode, and Execute.
When the program runs, program code is copied from secondary storage into main memory. CPU's program counter set to the first instruction of the program stored in memory where the program starts executing.
When a program is being executed, it goes through fetch-decode-cycle. which repeats over and over again until reaching the STOP instruction.
The processor check which next instruction to be executed, then the processor fetches that instruction value from the memory location. once the instruction being fetched it gets decoded and executed. This instruction processing cycle repeating until the CPU finds a stop instruction.
To complete the sentence - Methods can be overload methods correctly by providing different parameter lists for methods with the same name.
