What is the most important hardware component for computer processing?
The CPU (Central Processing Unit) performs most of the calculations which enable a computer to function, and is sometimes referred to as the “brain” of the computer. It is usually cooled by a heat sink and fan. Most newer CPUs include an on-die Graphics Processing Unit (GPU).
What is the hardware components of a computer?
Quite simply, computer hardware is the physical components that a computer system requires to function. It encompasses everything with a circuit board that operates within a PC or laptop; including the motherboard, graphics card, CPU (Central Processing Unit), ventilation fans, webcam, power supply, and so on.
What is core hardware and give three examples?
A processor core (or simply “core”) is an individual processor within a CPU. Many computers today have multi-core processors, meaning the CPU contains more than one core. For many years, computer CPUs only had a single core. Examples of Intel Core processors include the Core Duo, Core 2, Core i3, Core i5, and Core i7.

Which is part of the Trusted Computing Base concept?
Protection rings are part of the trusted computing base concept. The trusted computer base (TCB) is the sum of all the protection mechanisms within a computer and is responsible for enforcing the security policy. This includes hardware, software, controls, and processes.
Which is the intermediate between software and hardware?
Intermediate between software and hardware is ” firmware “, which is software that is strongly coupled to the particular hardware of a computer system and thus the most difficult to change but also among the most stable with respect to consistency of interface. The progression from levels of “hardness” to “softness” in computer…
