The CPU must be inserted into the Motherboard with ..................
Explanation
The CPU must be inserted into the motherboard using zero insertion force (ZIF) to avoid damaging the delicate pins on the CPU and the socket on the motherboard. Zero insertion force means that no pressure or force is required to insert the CPU, as it can be easily placed into the socket without any resistance. This ensures a safe and secure connection between the CPU and the motherboard, preventing any potential damage.Rate this question:

If the POST boots and stops, then user should access the ..........
Explanation
If the POST (Power-On Self Test) successfully boots but stops afterwards, the user should access the BIOS (Basic Input/Output System). The BIOS is a firmware that is responsible for initializing the hardware components of the computer and providing the necessary instructions for the operating system to load. By accessing the BIOS, the user can make changes to the system configuration, such as adjusting boot order or enabling/disabling certain hardware components, which may help in resolving the issue causing the system to stop after booting.Rate this question:

USB 2.0 can support ...... devices
Explanation
USB 2.0 can support up to 127 devices. This is because USB 2.0 uses a 7-bit addressing system, allowing for a maximum of 127 unique addresses. Each device connected to the USB 2.0 bus is assigned a unique address, and the bus can support up to this maximum number of devices.Rate this question:

Switches are sometimes called ................
Explanation
Switches are sometimes called multiport bridges because they both operate at the data link layer of the network and serve a similar purpose of connecting multiple devices together. Like bridges, switches have multiple ports that allow them to receive and forward data packets to the appropriate destination device. They use MAC addresses to make forwarding decisions, ensuring that data is sent only to the intended recipient. Therefore, the term "multiport bridges" accurately describes switches and highlights their ability to efficiently connect multiple devices in a network.Rate this question:

A switch maintains a table of the ................ for computers that are connected to each port
Explanation
A switch maintains a table of the MAC addresses for computers that are connected to each port. MAC addresses are unique identifiers assigned to network interfaces, allowing the switch to determine which devices are connected to each port and efficiently route network traffic. By keeping track of the MAC addresses, the switch can forward incoming data packets to the appropriate destination device based on its MAC address. This helps in organizing and managing the network connections effectively.Rate this question:

What is the special type of memory called when the CPU is executing one step of the programme and the remaining instructions are stored nearby?
-
Reduced Instruction Set Computer
-
Cache
-
BTX
-
Parity
-
BIOS
Correct Answer
A. CacheExplanation
Cache is a special type of memory that stores frequently accessed data and instructions near the CPU. It helps to improve the performance of the CPU by reducing the time it takes to access data from the main memory. When the CPU is executing one step of a program, the remaining instructions are stored in the cache, allowing for faster retrieval and execution. This helps to reduce latency and improve overall system performance.Rate this question:

Name one disk management tool?
-
Firewall
-
Antivirus software
-
GUI
-
Format
-
Loopback adapter
Correct Answer
A. FormatExplanation
Format is a disk management tool that allows users to prepare a storage device for use by organizing, partitioning, and initializing it. This tool erases all data on the disk and sets up a file system, making it ready to store files and folders. It is commonly used when installing a new operating system or when wanting to wipe a disk clean. By selecting the format option, users can customize the disk's file system, such as FAT32 or NTFS, depending on their needs and compatibility.Rate this question:

Operating systems perform the following functions
-
Control hardware access
-
Manage files and folders
-
All mentioned
-
Provide a user interface
-
Manage applications
Correct Answer
A. All mentionedExplanation
Operating systems perform all of the mentioned functions. They control hardware access by managing the communication between software and hardware components. They also manage files and folders by organizing and storing data in a structured manner. Operating systems provide a user interface that allows users to interact with the computer system. Additionally, they manage applications by allocating system resources and facilitating the execution of programs. Therefore, all of the mentioned functions are performed by operating systems.Rate this question:

Power management options of windows XP are: Pick 2
-
Hard drive
-
Shut down
-
Hibernate
-
CMOS
-
All of the above
Correct Answer(s)
A. Shut down
A. HibernateExplanation
The power management options of Windows XP include "Shut down" and "Hibernate". Shutting down the computer completely turns off all power to the system, while hibernating saves the current state of the computer to the hard drive and then powers off, allowing the user to resume their work later. The other options mentioned, such as "Hard drive" and "CMOS", are not power management options but rather components or settings related to the computer's hardware. Therefore, the correct answer is "Shut down" and "Hibernate".Rate this question:

The quality of printing is measured in....
-
Dpi
-
Mbps
-
Pixels
-

Correct Answer
A. DpiExplanation
The quality of printing is measured in dpi (dots per inch). DPI refers to the number of dots that can be placed in a one-inch line. The higher the dpi, the more dots are used to create an image, resulting in a higher quality print with more detail and sharpness. Therefore, dpi is the correct unit of measurement for printing quality.Rate this question:
