a. ENIACs b. microprocessors c. memory chips d. operating systems 5. 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.
A. used for short-term memory E. is installed onto the motherboard 5. This chapter describes the concepts behind how a CPU reads the contents from RAM. 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 hard drive, etc. Backing storage is non – volatile this means it is used to store data for a long time and is not lost when the computer is switched off. The central processing unit (CPU) is essential in all PC’s it is known as the brain of the computer. The CPU sends signals to control the other parts of the computer in basic terms. The CPU is an electronic machine that works on a list of things to do, called 'instructions'.
It serves as a circuit board that connects and communicates to all devices and components attached to it. It also provides connection to various parts of the computer and helps them work together. Importance of System Bus and I/O Bus The data bus portion of the system bus carries information between RAM and the CPU. Wider data buses enable more “lanes” of data to flow at the same time promote faster system performance. 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.
To determine the ComputerPrice, the following computation is: ComputerPrice = CompPrice + CPU_cost + RAM_cost + VideoCard_cost. Design: Things the program must do: 1. Input the computer base price 2. Process the various options to compute the additional costs 3. Total all the costs 4.
Calculations – Total all the cost. • CPU • Case • Power supply • Motherboard • Hard Drive • RAM • DVD • Sound Card • Monitor • Graphics Card • Operating System B. Program Design – Following the directions in the assignment, clearly write up your problem design in this section and comment your pseudocode. 1. Input the computer base price.
