Answer to Question 1

Every computer has a central processing unit (CPU), which is sometimes called the brain of the computer. 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. The CPU reads data and instructions from memory, and then stores the results of computations in main memory. In addition to random access memory, RAM, and one or more CPUs, all computers also include storage hardware, which is used to save data and programs.
