The component used to hold the processor in place with the help of clips and connecting the motherboard electrically to the processor, is known as____________
Correct Answer
C. Processor sockets
Explanation
The component used to hold the processor in place with the help of clips and connecting the motherboard electrically to the processor is known as a processor socket. The processor socket is specifically designed to fit a particular type of processor and ensures a secure connection between the processor and the motherboard. It also provides the necessary electrical connections for the processor to communicate with other components on the motherboard.
3.
Which one is NOT a type of bus?
Correct Answer
A. External
Explanation
The given question asks to identify the option that is not a type of bus. The options provided are External, Memory, Data, and Address. Among these options, External is not a type of bus. Buses are communication pathways that transfer data between different components of a computer system. Memory, Data, and Address are all types of buses that facilitate the transfer of specific types of information within a computer system. However, External does not pertain to a specific type of bus and is therefore the correct answer.
4.
Choose a DC voltage that power supply does NOT have?
Correct Answer
C. -3.3 volts
Explanation
The power supply does not have a -3.3 volts DC voltage because it only provides positive DC voltages (+3.3 volts and +5 volts) and negative DC voltages (-5 volts). Therefore, -3.3 volts is not available as an option for the DC voltage provided by the power supply.
5.
Which device does the processor uses to interact with rest of the hardware?
Correct Answer
D. BIOS chip
Explanation
The processor uses the BIOS chip to interact with the rest of the hardware. The BIOS (Basic Input/Output System) is a firmware that is stored on the BIOS chip and is responsible for initializing and controlling the hardware components during the boot process. It provides the necessary instructions for the processor to communicate with devices such as the memory, storage, and input/output devices. Without the BIOS chip, the processor would not be able to effectively interact with the rest of the hardware.
6.
System Lockup Errors can be best described as:
Correct Answer
B. System Lockup Error is an error condition that causes the system or an application to stop responding to user input
Explanation
System Lockup Errors can be best described as an error condition that causes the system or an application to stop responding to user input. This means that when a system lockup error occurs, the system or application becomes unresponsive and does not react to any commands or actions from the user. This can result in the need to forcefully shut down the system or application in order to regain control.
7.
What is the data transfer rate for IDE - ATA/2 PIO mode?
Correct Answer
C. 8.3 Mbps
Explanation
The data transfer rate for IDE - ATA/2 PIO mode is 8.3 Mbps. This mode refers to the Programmed Input/Output mode used in IDE (Integrated Drive Electronics) or ATA (Advanced Technology Attachment) devices. It allows for data transfer between the device and the computer's memory using the PIO protocol. The transfer rate of 8.3 Mbps indicates the speed at which data can be read from or written to the device in this mode.
8.
Which bus does the processor uses to communicate with other peripherals?
Correct Answer
B. System bus
Explanation
The processor uses the system bus to communicate with other peripherals. The system bus is responsible for transferring data, addresses, and control signals between the processor and other components such as memory, input/output devices, and the motherboard. It acts as a communication pathway, allowing the processor to send and receive information to and from different peripherals connected to the system.
9.
Which of the following computer case is generally used for Servers?
Correct Answer
D. Full Tower case
Explanation
Full Tower case is generally used for Servers because it provides ample space for multiple hard drives, expansion cards, and cooling systems. Servers require larger cases to accommodate their high-performance components and to allow for future upgrades. Full Tower cases also offer better airflow and cable management options, which are crucial for maintaining optimal server performance and preventing overheating. Additionally, the larger size of Full Tower cases allows for better organization and accessibility of server components, making maintenance and upgrades easier.
10.
What does DIMM stands for?
Correct Answer
C. Dual Inline Memory Module
Explanation
DIMM stands for Dual Inline Memory Module. DIMM is a type of computer memory module that is used to store data and instructions for the CPU. It is called "dual" because it has separate electrical contacts on both sides of the module, allowing for increased data transfer rates. The term "inline" refers to the fact that the module is plugged directly into the motherboard, rather than being connected via a cable. DIMMs are commonly used in desktop and server computers to provide high-speed and efficient memory storage.
11.
A device that translates digital signal of computers into analog signal, is known as?
Correct Answer
C. Modem
Explanation
A modem is a device that translates digital signals from computers into analog signals that can be transmitted over telephone lines. It allows computers to communicate with each other over long distances using existing telephone infrastructure. A modem converts the digital data into analog signals that can be transmitted through telephone lines, and then converts the analog signals back into digital data at the receiving end. This enables the transmission of data over long distances and facilitates internet connectivity.
12.
The Ultra DMA transfers data in burst mode at a rate of 33.3 MB per second. What is the transfer rate of Ultra DMA 100 standard?
Correct Answer
C. 100 Mbps
Explanation
Ultra DMA 100 standard has a transfer rate of 100 Mbps. This means that data can be transferred at a rate of 100 megabits per second.
13.
What is the full form of ATAPI?
Correct Answer
B. Advanced Technology Attachment Packet Interface
Explanation
ATAPI stands for Advanced Technology Attachment Packet Interface. This interface is an extension of the ATA (Advanced Technology Attachment) standard that allows for the connection of devices such as CD-ROM drives, DVD drives, and tape drives to a computer's motherboard. ATAPI enables these devices to communicate with the computer and transfer data using packets. This allows for faster and more efficient data transfer compared to the older ATA standard.
14.
Which one of the following ATA standards introduced SMART?
Correct Answer
C. ATA-3
Explanation
ATA-3 is the correct answer because it was the ATA standard that introduced SMART (Self-Monitoring, Analysis, and Reporting Technology). SMART is a feature that allows hard drives to monitor their own health and report any potential issues to the user. ATA-1, ATA-2, and ATAPI are not associated with the introduction of SMART.

Port COM1 is a type of _____________________
Correct Answer
C. Serial Port
Explanation
A Port COM1 is a type of serial port. Serial ports are used to connect devices such as modems, printers, and mice to a computer. They transmit data one bit at a time in a sequential manner, hence the term "serial." In contrast, parallel ports transmit multiple bits simultaneously. USB ports are a different type of interface used for connecting various devices, while PS/2 ports are typically used for connecting keyboards and mice.
