Answer to Question 1
Processing devices include the central processing unit (CPU), which is sometimes called the brain of the computer. Although the design of the CPU has nothing in common with the anatomy of a brain, this description is helpful, because the CPU does have the smarts of the machine. The CPU selects instructions, processes them, performs arithmetic and logical comparisons, and stores results of operations in memory. Some computers have two or more CPUs. A computer with two CPUs is called a dual-processor computer. Quad-processor computers have four CPUs. Some high-end computers have 16 or more CPUs. CPUs vary in speed, function, and cost.
The CPU works in conjunction with main memory, sometimes called RAM (random access memory). The CPU reads data and instructions only from main memory, processes that data, and places it back into main memory.
