Answer:
C)
Explanation:
One principle that can improve the efficiency of I/O would be to move processing primitives into hardware. Primitives are a semantic value representing something else such as words or numbers within the programming language. By moving them into hardware they system is able to read them at a much faster speed making the I/O more efficient.
The answer is True. Hacking is synonymous with unauthorized access most especially when it is intentional. Unauthorized access is defined as illegally gaining access to a file on a computer. It is the same as accessing a network or system without the permission of the owner.
Answer:
A) The risk/return Tradeoff is applicable to speculative risks.
Explanation:
Speculative risk always has a positive payoff and also a negative payoff , so option (b) is incorrect.
Speculative risk is a source of great concern for risk managers, so option (c)is incorrect.
Speculative risk is a category of risk that can be taken on voluntarily and will either result in a profit or loss , so option d is wrong
Pure risk, also called absolute risk, is a category of threat that is beyond human control and has only one possible outcome if it occurs: loss. Pure risk includes such incidents as natural disasters, fire or untimely death. so option (e) also incorrect
Answer:
True.
Explanation:
Virtualization can be defined as a technique used for the creation of a virtual platform such as a storage device, operating system, server, desktop, infrastructure or computing resources so as to enable the sharing of resources among multiple end users. Virtualization is usually implemented on a computer which is referred to as the "host" machine.
Generally, to use the virtualization technology on a computer, it must be enabled in the BIOS/UEFI).
Additionally, VMware tools can be installed on host computers to check which processes are having high CPU usage by using vimtop, as well as checking if vCenter Server is swapping.
Hence, one benefit of virtualization is that it allows for better use of already existing hardware that may not be seeing full utilization. Hardware components such as storage devices, central processing unit (CPU), random access memory (RAM), host computers are extensively put into use.
It depends on what it is.
