Hardware Parts Quiz G9

The given answer is true because a motherboard is indeed the main printed circuit board in a computer. It is responsible for connecting and providing power to various components such as the CPU, RAM, and storage devices. The motherboard also houses important connectors and slots for expansion cards, such as graphics cards and network adapters. Without a motherboard, the computer would not be able to function as it serves as the central hub for all hardware components to communicate with each other.

Today's computers typically come with a hard disk that contains several billion bytes of storage. This statement is true. Hard disks in modern computers have significantly increased in storage capacity over the years. A billion bytes, also known as a gigabyte, is a common unit of measurement for hard disk storage. With the advancement in technology, it is now common for computers to have hard disks that can store several billion bytes or even terabytes of data.

The statement that there is only one type of server that exists in today's world is false. In reality, there are multiple types of servers that exist, such as web servers, file servers, database servers, email servers, and many more. Each type of server serves a specific purpose and has different functionalities and configurations. Therefore, the correct answer is false.

The processor, also known as the central processing unit (CPU), is indeed considered the brain of the computer. It is responsible for executing instructions, performing calculations, and controlling the overall operation of the computer system. The processor carries out these tasks by fetching, decoding, and executing instructions from the computer's memory. Without a processor, a computer would not be able to perform any tasks or run any programs, making it an essential component and the primary determinant of a computer's performance.

LAN stands for Local Area Network. A LAN cable is a type of cable used to connect devices within a small geographical area, such as a home, office, or building. It allows for the transmission of data and communication between devices, enabling them to share resources and access the internet. LAN cables are commonly used in Ethernet networks to establish a wired connection between devices like computers, printers, and routers.

RAM stands for Random Access Memory. It is a type of computer memory that allows data to be accessed in any random order, rather than sequentially. It is used by the computer's operating system, software applications, and data that are currently in use to provide fast and temporary storage for data. RAM is volatile memory, meaning that its contents are lost when the computer is powered off or restarted.

The correct answer is "Projector is an output device that can take images generated by a computer and reproduce them onto a screen." This answer accurately describes a projector as a device that can display images from a computer onto a screen. It highlights the main function of a projector, which is to project images for public viewing.

Intel is the most popular brand for a processing chip because it has established itself as a leader in the industry. Intel has a long history of producing high-quality and reliable chips that are widely used in various devices, including computers, laptops, and servers. The company has consistently innovated and improved its chip technology, offering faster processing speeds, better power efficiency, and advanced features. Intel's reputation for performance and reliability has made it the preferred choice for many consumers and businesses around the world.

RAM (Random Access Memory) is a type of computer memory that is responsible for temporarily storing data that the CPU (Central Processing Unit) needs to access quickly. It is physically located on the motherboard, which is the main circuit board of the computer that connects all the components together. Therefore, the correct answer is motherboard.

ROM stands for Read-Only Memory, which is a type of permanent memory in a computer. Unlike other types of memory, such as RAM, the data stored in ROM is not erased when the computer is turned off. It contains instructions that are permanently written during manufacturing and cannot be modified or erased by normal computer operations. Therefore, the statement that ROM is a permanent memory and does not disappear when the computer is turned off is true.

The given statement is incorrect. The scanner is not an "output" device, but rather an "input" device. A scanner is used to convert physical documents or images into digital format, allowing them to be stored or manipulated on a computer. Therefore, the correct answer is False.

"GHz" stands for Gigahertz, which is a unit of measurement used to quantify the frequency of a processor or computer's clock speed. It represents one billion cycles per second. This unit is commonly used to describe the speed and performance of computer processors, indicating how many instructions a processor can execute in a given amount of time.

The statement "CCTV is available for public to monitor" is false. CCTV (Closed-circuit television) is a system of surveillance cameras that are typically used for security purposes. These cameras are usually installed in public areas to monitor and record activities for safety and security reasons. However, the access to view or monitor the CCTV footage is usually restricted to authorized personnel such as security officials or law enforcement agencies, and not available for the general public to monitor.

A system fan or computer fan is responsible for bringing cool air into the case and blowing out hot air. This helps to regulate the temperature inside the computer and prevent heat damage to the CPU and other components. By circulating the air, the system fan ensures that the heat generated by the CPU is dissipated effectively, maintaining optimal operating conditions for the computer.

A graphics card is also commonly referred to as a video card. It is a hardware component that is responsible for rendering images, videos, and other visual elements on a computer screen. The term "video card" is often used interchangeably with "graphics card" to describe this essential component of a computer system.

CCTV stands for Closed Circuit Television, which refers to a system of video surveillance that uses cameras to monitor a specific area or space. The term "closed circuit" indicates that the video feed is only accessible to a limited number of people or devices, as opposed to being broadcasted publicly. The acronym CCTV is commonly used to describe this type of surveillance technology.

VGA stands for Video Graphics Array. It is a display standard that was introduced by IBM in 1987. VGA is commonly used to refer to the resolution of 640x480 pixels, which was the standard resolution for computer displays for many years. The term "video graphics array" accurately describes the purpose and function of this display standard, as it is used to display graphics and images on a screen.

The system fan is located in the Central Processing Unit (CPU). The CPU generates a lot of heat while processing data, and the system fan is responsible for cooling down the CPU to prevent overheating. It helps in maintaining the optimal temperature for the CPU to function efficiently.

A router is a small electronic device that connects multiple computer networks together using wired or wireless connections. It allows devices within these networks to communicate with each other and also provides access to the Internet. Routers are typically connected to two or more data lines from different networks, and they analyze the contents of data packets transmitted within a network to ensure efficient and accurate routing of the information.

The four primary functions of the processor are fetch, decode, execute, and writeback. The fetch function retrieves instructions from memory, the decode function interprets these instructions, the execute function carries out the instructions, and the writeback function stores the results back into memory. These functions are essential for the processor to perform its tasks and execute programs effectively.
