CHS Exam: Computer Quiz!

Explanation
The correct answer is "delete." When starting up a computer, pressing the "delete" key allows access to the BIOS setup. The BIOS setup is a program that controls the basic functions of a computer, such as boot order, hardware configuration, and system settings. By pressing the "delete" key at startup, users can modify these settings to customize their computer's behavior.

Explanation
Software refers to the set of instructions or programs that tell a computer what to do and how to do it. It includes all the applications, operating systems, and other programs that enable the computer to perform specific tasks. Unlike hardware, which refers to the physical components of a computer system, software is intangible and can be installed, updated, and removed as needed. Therefore, software is the correct answer to the question as it accurately describes the instructions that tell the computer what to do and how to do it.

Explanation
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 is the main component that carries out the majority of the computer's processing tasks, including running programs and managing data. RAM (Random Access Memory) and ROM (Read-Only Memory) are types of computer memory, while HDD (Hard Disk Drive) is a storage device. While these components are important for the overall functioning of a computer, the CPU is the primary component that controls and coordinates all operations.

Explanation
Random Access Memory (RAM) is a type of computer memory that allows data to be read or written in almost the same amount of time, regardless of the physical location of data inside the memory. It is a volatile memory, meaning that its contents are lost when the power is turned off. In computing, RAM is used to store data that is actively being used by the computer's operating system, applications, and processes. Therefore, the correct answer is Random Access Memory.

Explanation
A flash drive can connect to the USB port of a computer system. USB (Universal Serial Bus) ports are commonly used for connecting various external devices to a computer, including flash drives. These ports provide a fast and convenient way to transfer data between the flash drive and the computer. PS/2 ports, serial ports, and parallel ports are older types of ports that were used for connecting keyboards, mice, and printers, respectively, but they are not commonly found on modern computer systems.

Explanation
The ATX power connector is used to supply electricity to the motherboard. ATX stands for Advanced Technology Extended, and it is a standard form factor for computer power supplies and motherboards. The ATX power connector provides the necessary power to the motherboard, allowing it to function properly.

Explanation
SATA (Serial Advanced Technology Attachment) is the current standard interface for connecting the internal hard drive and optical drives to the motherboard. It replaced the older EIDE (Enhanced Integrated Drive Electronics) and SCSI (Small Computer System Interface) interfaces. SATA offers faster data transfer rates and better performance compared to its predecessors, making it the preferred choice for modern computer systems. USB is a different type of interface mainly used for connecting external devices, while SATA is specifically designed for internal storage devices.

Explanation
The correct answer is "Motherboard". A motherboard is a main circuit board that connects and holds together all the essential components of a computer system. It provides a platform for these components to communicate and interact with each other. It is also known as a printed circuit board because it contains printed circuits that connect various electronic components on the board. The motherboard plays a crucial role in the functioning and performance of a computer system.

Explanation
The Northbridge is an integrated circuit that handles the communication between the Central Processing Unit (CPU), Accelerated Graphics Port (AGP), and the memory. It plays a crucial role in facilitating the transfer of data and instructions between these components, ensuring efficient and speedy performance. The Northbridge is responsible for tasks such as coordinating memory access, managing data flow, and controlling the AGP interface.

Explanation
IDE cables, or Integrated Drive Electronics cables, are used to connect the hard disk drive to the motherboard. These cables transmit data between the hard drive and the motherboard, allowing the computer to access and store information on the hard drive. IDE cables typically have a wide, flat ribbon design with multiple connectors for connecting multiple drives. They are commonly used in older computer systems, while newer systems may use SATA cables instead. Power cables, on the other hand, are used to provide electrical power to the hard drive, while disk cables and boot straps are not specific types of cables used for connecting hard drives to the motherboard.
