b. Megabyte 3. Which answer lists the correct number of bits associated with each term? c. 64 bits per quadruple word 4. Which of the following answers are true about random-access memory (RAM) as it is normally used inside a personal computer? (Choose two answers.)
The CPU tells the RAM which address holds the data that the CPU wants to read 6. A user has opened a word processor, typed the numbers 123456789, and stored the document as a file called report1. Which of the following determines, in part, what bits the computer stores in the file to represent the typed into the report? C. Character set 7. A user has opened a calculator application, typed the numbers 123456789, and then done some math problem using this number.

The computer stores a program while the program is running, as well as the data that the program is working with, in __________. a. secondary storage b. the CPU c. main memory d. the microprocessor 6. This is a volatile type of memory that is used only for temporary storage while a program is running. a. RAM b. secondary storage c. the disk drive d. the USB drive 7.
The memory management function keeps track of the status of each memory location, either allocated or free. It determines how memory is allocated among competing processes, deciding who gets memory, when they receive it, and how much they are allowed. When memory is allocated it determines which memory locations will be assigned. It tracks when memory is freed or unallocated and updates the status. Paged allocation divides the computer's primary memory into fixed-size units called page frames, and the program's address space into pages of the same size.
Firmware is software contained in ……. chips. 7. Instructions that control much of the computer’s input/output functions, such as communicating with disks, RAM, and the monitor kept in the System ROM chips, are known as the……. .
The power lines in the system bus transfer power from the motherboard’s connection to the power supply to the integrated circuits (ICs or chips) and expansion boards connected to the motherboard. The control lines in the system bus controls the transmission and movement of information between devices connected to the motherboard. The address bus is used to “pick up” information from the correct memory location among the gigabytes of RAM in computer systems and “deliver” new programs and changes to the
The actual machinery - wires, transistors and circuits is called hardware; the instructions and data are called software. All general purpose computers require the following hardware components: (i) Central Processing Unit (CPU): The ‘brain’ of the computer, the component that actually executes instructions. (ii) Memory : It enables a computer to store, at least temporarily, data and programs. (iii) Input device : Usually a keyboard or mouse is used to read data and programs into the computer. (iv) Output device: A display screen, printer, etc.
Retrieval: the process in which stored information is accessed by the brain similar to that of a software command that opens a file from the hard drive on a computer. (Passer & Smith, 2007). It continues to influence thinking around how memory
