It is a device that works with discrete-distinct data such as 0 or 1.
- A.
Digital Device
- B.
Analog Device
- C.
Input Device
- D.
Output Device
Correct Answer
A. Digital DeviceExplanation
A digital device is the correct answer because it is specifically designed to work with discrete data, which is represented by binary digits (0 or 1). Unlike analog devices that work with continuous data, digital devices process and store information in a binary format, allowing for precise and accurate calculations. Input and output devices, on the other hand, refer to the means by which data is entered into or displayed by a device, and do not necessarily imply the use of digital technology.Rate this question:

It is a system of instructions and data directly executed by a computer's centralprocessing unit.
- A.
Program
- B.
Pseudocode
- C.
Machine Language
- D.
Compiler
Correct Answer
C. Machine LanguageExplanation
Machine language is the correct answer because it refers to the set of instructions and data that can be directly executed by a computer's central processing unit. It consists of binary code that represents specific operations and addresses in the computer's memory. This low-level programming language is specific to the computer's hardware and is often used by assembly language programmers to write software that can directly control the computer's hardware components. It is the closest representation of how a computer actually understands and executes instructions.Rate this question:

- A.
Read Only Memory
- B.
Virtual Memory
- C.
Random Access Memory
- D.
Programmable Read Only Memory
Correct Answer
C. Random Access MemoryExplanation
Random Access Memory (RAM) is a type of computer memory chip that allows instructions and data to be stored, changed, and retrieved by the user. Unlike Read Only Memory (ROM) which is non-volatile and cannot be modified, RAM is volatile and can be read from and written to. It provides temporary storage for data that is actively being used by the computer's operating system and applications. When the computer is turned off or restarted, the data stored in RAM is lost. Virtual Memory and Programmable Read Only Memory are not accurate descriptions for this type of memory.Rate this question:

What is the equivalent decimal value of AE103 base-16?
- A.
748295
- B.
744560
- C.
712963
- D.
741680
Correct Answer
C. 712963Explanation
The correct answer is 712963 because AE103 in base-16 is equal to 712963 in base-10. In hexadecimal (base-16), each digit represents a power of 16. A is equivalent to 10, E is equivalent to 14, and 1 is equivalent to 1. So, AE103 can be calculated as (10 * 16^4) + (14 * 16^3) + (1 * 16^2) + (0 * 16^1) + (3 * 16^0) = 712963.Rate this question:
