CIS 105 Exam #2 Questions With Complete Solutions (graded A+ 2024/2025)

CIS 105 Exam #2 Questions With Complete Solutions (graded A+ 2024/2025) -Kilobye (KB)? (ANS) Approximately 1,000 bytes. -Megabyte (MB)? (ANS) About 1 million bytes. -Gigabyte (GB)? (ANS) Around 1 billion bytes. -Terabytes (TB)? (ANS) Around 1 trillion bytes. Today personal computers are capable of this amount of storage. -The CPU consists of which two parts? (ANS) the control unit and the arithmetic logic unit (ALU). -CPU Control Unit? (ANS) Coordinates activities of all the other computer components. -ALU? (ANS) Responsible for performing all arithmetic calculations (addition, subtraction, multiplication, and division). Also makes logic and comparison decisions, such as comparing items, to determine if one is greater than, less than, or equal to another. -Four Steps in the Machine Cycle? (ANS) 1. it FETCHES the required piece of data or instruction from random access memory (RAM), the temporary storage location for all the data and instructions the computer needs while it's running. 2. It DECODES the instruction into something the computer can understand. 3. It EXECUTES the instruction. 4. It STORES the result to RAM before fetching the next instruction. -Hyperthreading? (ANS) When CPUs began to execute more than one instruction at a time. Introduced in 2002, it provides quicker processing of information by enabling a new set of instructions to start executing before the previous set has finished. Allows two different programs to be processed at one time, but they're sharing the computing resources of the chip. -Memory Modules (memory cards)? (ANS) RAM appears in the system on these small circuit boards that hold a series of RAM chips and fit into special slots on the motherboard. Most memory boards in today's systems are packaged as a dual inline memory module (DIMM), a small circuit board that holds several memory chips.
