Which of the following is true about the process of read data, as described in the chapter? a. 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.
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 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

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.
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. The hardware memory management unit maps pages to frames. The physical memory can be allocated on a
There is a control unit, which manages the process of moving data and programs into and out of the memory, and also executes the programs instructions, one by one. There is an input and output which is the computers connection to the user. The arithmetic logic unit is responsible for carrying out calculations
