The speed of the computer is dependent on the?
- A.
L1 cache
- B.
RAM
- C.
CPU
- D.
L3 cache
Correct Answer
C. CPUExplanation
The speed of a computer is primarily determined by the CPU (Central Processing Unit). The CPU is responsible for executing instructions and performing calculations, making it the most crucial component for overall system performance. While other factors such as cache and RAM can also affect the speed, the CPU is the main determinant. The CPU's clock speed, number of cores, and architecture play a significant role in determining how fast a computer can process tasks and run programs.Rate this question:

The CPU speed is measured in?
- A.
Gigabits
- B.
Bits per second
- C.
Hertz
- D.
Mbs
Correct Answer
C. HertzExplanation
The CPU speed is measured in Hertz. Hertz is the unit of frequency and it represents the number of cycles per second. In the context of a CPU, it refers to the number of instructions or operations the CPU can perform in a second. A higher CPU speed in Hertz means that the CPU can process more instructions or operations in a given time, resulting in faster performance.Rate this question:

- A.
Processor
- B.
Registers
- C.
Motherboard
- D.
RAM
Correct Answer
B. RegistersExplanation
The CPU is made up of 3 main parts: the ALU, Control Unit, and Registers. Registers are small, high-speed storage locations within the CPU that hold data that is being processed. They are used to store instructions, data, and intermediate results during the execution of a program. Registers play a crucial role in the overall performance of the CPU by providing quick access to data and instructions, reducing the need to retrieve information from slower memory locations. Therefore, Registers is the correct answer as it is one of the main parts of the CPU.Rate this question:

CISC is a type of system architecture which stands for?
- A.
Complex Instructions Super Computer
- B.
Complex Instruction Set Computer
- C.
Complex Instructions System Components
Correct Answer
B. Complex Instruction Set ComputerExplanation
CISC stands for Complex Instruction Set Computer. It is a type of system architecture that emphasizes a large number of complex instructions. In a CISC architecture, each instruction can perform multiple low-level operations, allowing for more complex and powerful operations to be executed in a single instruction. This contrasts with RISC (Reduced Instruction Set Computer) architectures, which prioritize simpler instructions that can be executed more quickly. CISC architectures are often used in applications that require a high level of computational power and support for complex operations.Rate this question:

Correct Answer
B. RegisterExplanation
A small permanent storage location within the CPU used for a specific purpose is called a register. Registers are high-speed storage areas that hold data that is being processed or temporarily stored for immediate use. They are located within the CPU and are used to store instructions, data, and addresses during the execution of a program. Registers are faster to access than main memory, making them ideal for storing frequently accessed data and improving the overall performance of the CPU.Rate this question:

The type of registers that is used for high speed temporary storage of program variables is called ?
- A.
Accumulator
- B.
General Registers
- C.
L1 Registers
- D.
L3 Registers
Correct Answer
B. General RegistersExplanation
General Registers are a type of registers that are used for high-speed temporary storage of program variables. These registers allow the processor to quickly access and manipulate data during program execution. They are typically located within the CPU and are used to store intermediate results, operands, and other data that is frequently accessed by the program. General Registers play a crucial role in improving the overall speed and efficiency of the program execution by reducing the need to access slower forms of memory.Rate this question:

Which of the following is not a function of a register?i. It stores data values from other locationsii. It does addition and subtractioniii. It tests contents for conditions such as zero or positiveiv. It speeds up the CPU.
- A.
All of the above
- B.
I, ii, and iii
- C.
I, iii and iv
- D.
Ii, iii and iv
- E.
None of the above
Correct Answer
A. All of the aboveExplanation
A register is a small, high-speed storage area within the CPU. It is used to store data values from other locations, perform arithmetic operations such as addition and subtraction, and test the contents for conditions such as zero or positive. However, it does not directly speed up the CPU. The speed of the CPU is determined by factors such as clock speed, cache size, and architecture. Therefore, the correct answer is "All of the above" as all the given options describe functions of a register except for the statement about speeding up the CPU.Rate this question:

Which of the following is a temporal storage?
- A.
Register
- B.
ROM
- C.
RAM
- D.
CMOS
Correct Answer
C. RAMExplanation
RAM stands for Random Access Memory, and it is a type of temporary storage in a computer system. It is used to store data that is actively being used by the computer's processor. Unlike ROM (Read-Only Memory) which stores permanent data that cannot be modified, RAM allows for read and write operations, making it a suitable choice for temporary storage. Registers, on the other hand, are small, high-speed storage locations within the processor itself, used for holding frequently accessed data. CMOS (Complementary Metal-Oxide-Semiconductor) is a type of technology used in manufacturing computer chips and is not a form of storage.Rate this question:

The type of RAM that does not need refreshing is called a RAM?
- A.
Static
- B.
Dynamic
- C.
EDO
- D.
ECC
Correct Answer
A. StaticExplanation
Static RAM (SRAM) is a type of RAM that does not require refreshing. Unlike dynamic RAM (DRAM), which needs to be refreshed constantly to retain data, SRAM uses flip-flops to store data, which does not require refreshing. This makes SRAM faster and more reliable than DRAM, but it is also more expensive and consumes more power. Therefore, the correct answer is Static.Rate this question:

EEPROM is a type of ROM which stands for??
Correct Answer
Electrically Erasable Programmable ROMExplanation
EEPROM stands for Electrically Erasable Programmable ROM. EEPROM is a type of ROM that can be erased and reprogrammed electronically. Unlike traditional ROM, which is read-only and cannot be altered, EEPROM allows for data to be written, erased, and rewritten multiple times. This makes it a versatile and flexible storage option for applications that require non-volatile memory that can be updated as needed.Rate this question:

Cache memory is an example of a ?
- A.
Static RAM
- B.
Dynamic RAM
- C.
Synchronous RAM
- D.
Rambus RAM
Correct Answer
C. Synchronous RAMExplanation
Cache memory is an example of Synchronous RAM because it operates using a clock signal to synchronize data transfers between the cache and the processor. Synchronous RAM, also known as SDRAM, is designed to provide faster and more efficient data access compared to other types of RAM. It is commonly used in cache memory due to its ability to match the speed of the processor, ensuring quick and synchronized data transfers.Rate this question:

The process by which a computer retrieves a program instruction from its memory, determines what actions the instruction requires, and carries out those actions is called ?
- A.
Fetch-execute-decode cycle
- B.
Fetch-execute cycle
- C.
Fetch-retrieve cycle
Correct Answer
A. Fetch-execute-decode cycleExplanation
The process by which a computer retrieves a program instruction from its memory, determines what actions the instruction requires, and carries out those actions is called the fetch-execute-decode cycle. This cycle involves fetching the instruction from memory, decoding it to understand what actions need to be performed, and then executing those actions. This cycle is repeated for each instruction in a program, allowing the computer to effectively carry out the desired tasks.Rate this question:
