A program does nothing more than tell the computer how to accept some type of input, manipulate that input, and spit it back out again in some form that humans find useful. Table 1 lists some common types of programs, the types of … Computers use two types of storage: Primary storage and secondary storage. The CPU interacts closely with primary storage, or main memory, referring to it for both instructions and data. For this reason this part of the reading will discuss memory in the context of the central processing unit. 11. • 1. Choose the part of your computer where you want to save your document in the “save in” box. • 2. In the “file name” box, enter the name of your document. • 3. Now, click on “save”, in order to confirm your selections. 12.Central Processing Unit (CPU) The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it. Without a CPU, we could not run programs on a …And the logical next step will be to create quantum computers, which will harness the power of atoms and molecules to perform memory and processing tasks.
