Basic Hardware Knowledge Quiz

USB (Universal Serial Bus) is the correct answer because it is a commonly used port in today's computers. USB ports are versatile and can be used to connect various peripherals such as keyboards, mice, flash drives, and fingerprint scanners. The USB port has become the standard for connecting devices to computers due to its convenience and compatibility with a wide range of devices.

The CPU, or Central Processing Unit, is often referred to as the "brain" of the computer because it is responsible for executing instructions and performing calculations. It communicates with other computer components, such as the RAM and motherboard, to send and receive instructions. The CPU is the main component that processes data and performs tasks, making it a crucial part of the computer's functionality.

The motherboard is the main circuit board of the computer that connects all other components such as the supply box, audio card, video card, etc. It serves as a central hub for communication and data transfer between these components. The motherboard also houses important components like the CPU and RAM, making it a crucial component for the computer's functionality.

The BIOS (Basic Input/Output System) is indeed stored in a ROM (Read-Only Memory) chip that is integrated into the motherboard. This chip contains the firmware that initializes the hardware components of the computer and provides the necessary instructions for the computer to boot up. Since ROM is non-volatile memory, the BIOS remains intact even when the computer is powered off. Therefore, the statement "BIOS is stored in a ROM chip integrated to the motherboard" is true.

The correct answer is Hard Drive. The explanation is that the hard drive is a device that is responsible for storing all the physical data on a computer system. This includes files, folders, programs, and the operating system. The hard drive provides long-term storage and allows users to access and retrieve their data whenever needed.

This statement is false because it is possible for an audio card to be integrated onto the motherboard. Integrated audio cards, also known as onboard audio, are commonly found on modern motherboards. These integrated audio cards provide basic audio functionality without the need for a separate audio card.

ROM (Read-Only Memory) is a type of storage that is written with data and cannot be altered or modified afterwards. Once the data is written onto ROM, it becomes permanent and cannot be changed. The only way to get rid of the data is by physically destroying the device that contains the ROM. Therefore, the statement "True" accurately describes the characteristics of ROM.

RAM stands for Random Access Memory. It is a type of computer memory that stores data and instructions temporarily while the computer is running. RAM allows the computer to quickly access and manipulate this data, which is necessary for the smooth functioning of the computer. However, once the computer is turned off, the data stored in RAM is lost, as it requires power to retain the information. Therefore, any processes running in RAM are deleted when the computer is shut down.

The statement "1024KB is equal to 1 GB" is false. In the binary system, 1 kilobyte (KB) is equal to 1024 bytes, and 1 gigabyte (GB) is equal to 1024 megabytes (MB), which in turn is equal to 1024 kilobytes. Therefore, 1024KB is equal to 1 megabyte (MB), not 1 GB.

Reformatting the hard drive and reinstalling the operating system is indeed the best way to get rid of a virus on a computer. This process erases all the data on the hard drive, including any viruses or malware that may be present. By reinstalling the operating system, the computer starts fresh with a clean slate, ensuring that any lingering viruses are completely removed. It is important to note that this method should only be used as a last resort, as it also erases all other data and programs on the computer.

A heat sink is a device made with zinc or copper alloy that is attached to the CPU with a thermal material. Its purpose is to draw away the heat generated by the CPU, helping to prevent overheating and ensuring optimal performance. By providing a large surface area and fins, a heat sink increases the contact area between the CPU and the surrounding air, allowing for efficient heat dissipation. This helps to maintain the CPU's temperature within safe limits, preventing damage and ensuring the smooth operation of the computer system.

This statement is false because there are other important features to consider when purchasing a new computer, such as the operating system, display resolution, battery life, connectivity options, and build quality. These factors can greatly impact the overall performance and user experience of the computer. Therefore, it is not accurate to say that only hard drive size, RAM size, CPU speed, and video card size are the only important features to consider.

A NIC (Network Interface Card) is a device that allows a computer to connect and communicate over a network. It provides an Ethernet connection with varying speeds (10, 100, 1000Mbps and higher). In order to access the network, the NIC card must be physically connected to a cable that leads to a device such as a switch, router, or modem. The NIC card acts as an interface between the computer and the network, enabling network access and communication.

RAM, Video Card, and Sound (Audio) Card are devices that can be integrated into the motherboard. The motherboard provides slots, connectors, and interfaces to connect these devices directly to it, allowing them to function as an integral part of the computer system. The Hard Drive, on the other hand, is not typically integrated into the motherboard but rather connected to it via cables or interfaces such as SATA. Therefore, the correct answer is B, D.

To find out how large your hard drive is in terms of memory space, you can follow steps A and B. Clicking on My Computer will allow you to access the Disk Management option, which provides information about your hard drive's memory space. Additionally, right-clicking on My Computer and selecting Properties will also give you information about your hard drive's memory space. Therefore, both steps A and B are correct and will help you determine the size of your hard drive.
