The register stores data that the processor is using.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The register is a small, high-speed storage area within the processor that holds data and instructions that the processor is currently using. It allows for quick access and retrieval of data, which helps in improving the overall performance of the processor. Therefore, the statement that the register stores data that the processor is using is true.Rate this question:

This is a small block of fast memory stored in the CPU or in-between the CPU and memory. this can be accessed much faster than the main memory and if this was removed your computer would run at 10% the current speed, this is...
Correct Answer
cacheExplanation
Cache is a small block of fast memory stored in the CPU or in-between the CPU and memory. It can be accessed much faster than the main memory. If the cache was removed, the computer would run at 10% of its current speed. Therefore, the correct answer is cache.Rate this question:

Operating systems do the following:
- A.
Create a file system
- B.
Manages security through usernames and passwords
- C.
Creates HTML
- D.
Transfers programs into and out of memory
Correct Answer(s)
A. Create a file system
B. Manages security through usernames and passwords
D. Transfers programs into and out of memoryExplanation
Operating systems perform several essential functions, including creating a file system, managing security through usernames and passwords, and transferring programs into and out of memory. Creating a file system involves organizing and managing files on a storage device. Managing security through usernames and passwords ensures that only authorized users can access the system and its resources. Transferring programs into and out of memory involves loading programs from storage into memory for execution and saving them back to storage when they are no longer needed. These functions are fundamental to the operation and management of an operating system.Rate this question:

Assembly Code is a low level language.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Assembly code is indeed a low-level language. It is a type of programming language that is closely related to machine code and is specific to a particular computer architecture. Assembly code uses mnemonic instructions that directly correspond to the machine code instructions of the computer's processor. It is considered low-level because it provides a close representation of the hardware and allows for direct manipulation of the computer's resources, such as registers and memory. This makes assembly code more efficient and faster than high-level languages, but also more complex and harder to write and understand.Rate this question:

Select the correct components of a CPU.
- A.
Arithmetic and Logic Unit
- B.
Control Unit
- C.
Internal Buses
- D.
RAM
- E.
Logic Gates
- F.
Bill Gates
- G.
SRAM
Correct Answer(s)
A. Arithmetic and Logic Unit
B. Control Unit
C. Internal Buses
E. Logic GatesExplanation
The correct components of a CPU are the Arithmetic and Logic Unit (ALU), Control Unit, Internal Buses, and Logic Gates. The ALU performs mathematical operations and logical comparisons, while the Control Unit coordinates and controls the flow of data within the CPU. Internal Buses are responsible for transferring data between different components of the CPU. Logic Gates are electronic circuits that perform basic logical operations. These components work together to execute instructions and perform calculations in a CPU.Rate this question:
