A user has opened a calculator application, typed the numbers 123456789, and then done some math problem using this number Which of the following determines, in part, what bits the computer stores in RAM to represent the number123456789? d. the binary equivalent of decimal 123456789 8.
(Choose two answers.) a. Used for short-term memory b. Used for long-term memory c. Used to process data d. Connects to the CPU over a bus using a cable e. Is installed onto the motherboard 5. This chapter describes the concepts behind how a CPU reads the contents from RAM.
Holograms made up about 95% of ABNH’s sales; ABNH controlled 8% of the total security hologram market. They owned several patents that covered their security features and production processes. ABNH was vertically integrated while other companies in the industry tended to focus on one or more segments of the value chain and used cross-licensing or
6.Synchronous DRAM, a type of DIMM memory that synchronizes itself with the computer’s system clock to provide a synchronization between the memory and the computer processor. 7. The primary benefit of DDR3 is the ability to transfer I/O data at eight times the speed of the memory cells it contains. DDR3 standard allows for chip capacities of 512 megabits to 8 gigabits, effectively enabling a maximum memory module size of 16 gigabytes. 8.
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 are true about random-access memory (RAM) as it is normally used inside a personal computer? A.Used for short term memory, E. Is installed on the motherboard 5.
a. microprocessor c. clock speed b. RAM cache d. megahertz 7. Megahertz is a measurement of ____. a. the amount of memory b. the amount of RAM c. the speed of the microprocessor d. cache memory 8. The devices shown in the figure above are all ____ devices. a. input c. storage b. pointing d. All of the above 9.
Therefore, we had 36 data points for micrometer calibration. The caliper was calibrated in very similar way as micrometer. The six gage blocks caliper used were 0.105, 0.11, 0.16, 0.3, 0.5, 2 inch. Record all data in lab notebook. After the calibration, select one of unknown blocks in the shelf.
Lab 1 This lab exercise covers: * an introduction to C programming * arithmetic statements * Standard input output * Mathematical functions Exercise 1.1 Write a program that prints the string “Computing Systems & Programming” to the screen, reads an integer from the keyboard, and print the integer to the screen. Exercise 1.2 Write the following program. Compile, link and run it. #include<stdio.h> int main () { int year; float height; year = 21; height = 1.77; printf("Ali is %d years old and %f meter height\n", year, height); return 0; } Exercise 1.3 Write a program that demonstrates the use of the +,-,* and / operators for integers. Type the following program.
