The distinction between "computer architecture" and "computer organization" has become very fuzzy, if no completely confused or unusable. Computer architecture was essentially a contract with software stating unambiguously what the hardware does. The architecture was essentially a set of statements of the form "If you execute this instruction (or get an interrupt, etc.), then that is what happens. Computer organization, then, was a usually high-level description of the logic, memory, etc, used to implement that contract: These registers, those data paths, this connection to memory, etc.
Programs written to run on a particular computer architecture should always run correctly on that architecture no matter what computer organization (implementation) is used.
For example, both Intel and AMD processors have the same X86 architecture, but how the two companies implement that architecture (their computer organizations) is usually very different. The same programs run correctly on both, because the architecture is the same, but they may run at different speeds, because the organizations are different. Likewise, the many companies implementing MIPS, or ARM, or other processors are providing the same architecture - the same programs run correctly on all of them - but have very different high - level organizations inside them.
I think that A could be the correct answer. The others are not as credible as A.
Answer: Awnser below.
Explanation:
Basically, what you're going to need for a computer from my basic knowledge is a motherboard, of course, this is so you can actually use your computer. You'll need a PSU, or so called, a power supply. This will give power to your motherboard and the other components with it. You will need a CPU, this is basically the brains of the computer. This will run your operating system, and main componets. A GPU, this will give you a display for your monitor. And of course, ram. Ram will be giving you display for your monitor, and for running tasks.
For more components, you would need a hard drive, or an SSD, which will store your files and operating system. And of course, a keyboard, mouse, and monitor.
