Understanding Computer Hardware Components Quiz

A CPU, or Central Processing Unit, is the primary component of a computer responsible for executing instructions and performing calculations.

An external modem is a device that converts digital signals from a computer into analog signals that can be transmitted over telephone lines, allowing the computer to connect to the internet. Internal hard drives, wireless routers, and graphics cards do not perform this function.

A Flash Drive is a portable storage device that utilizes flash memory to store data. It is commonly used for transferring files between devices.

A floppy drive is a type of storage device that reads and writes data to a small, portable disk known as a floppy disk. It was commonly used in the past for storing and transferring data between computers.

A Hard Drive is a type of storage device used to store and retrieve digital information.

A modem is a device that connects a computer to the internet, while a router is used to direct internet traffic, a monitor displays information, and a keyboard is used for input.

The motherboard is the central printed circuit board in many modern computers and holds many of the crucial components of the system such as the CPU, RAM, and other peripherals.

The correct answer is 'Mouse' because it is a small rodent commonly found in households known for its squeaking and scurrying behavior.

A Portable External Hard Drive is a type of storage device that connects to a computer via USB or other means to provide additional storage capacity for storing files and data. Unlike internal hard drives, external hard drives are portable and can be easily disconnected and carried around.

An Optical Disk Drive is primarily a storage device used for reading and writing data on optical discs such as CDs, DVDs, and BluRay discs. It is not classified as an input device, output device, or processing device.

A wireless router allows devices to connect to the internet without the need for physical cables.

A sound card is a hardware device that enables a computer to produce sound. It is responsible for processing and outputting audio signals.

A video card is responsible for rendering images and displaying graphics on a computer monitor. The Central Processing Unit (CPU) handles the processing of data, Random Access Memory (RAM) stores temporary data for quick access, and the Power Supply Unit (PSU) provides power to the computer components.

Coaxial cables are known for their ability to transmit high-frequency signals efficiently with low signal loss. Fiber optic cables use light pulses to transmit data, twisted pair cables consist of pairs of insulated wires twisted together, and ribbon cables are flat cables with multiple conducting wires running parallel to each other.

The yellow component cord is used to transmit video signals, making it essential for displaying visuals on a screen or monitor.

The red and white cords are typically used for audio connections, specifically for connecting the left and right speakers in a sound system setup.

The correct answer refers to the types of devices commonly using plugs, which are headphones and microphones. The incorrect answers provided do not align with the typical items that would require these specific plugs.

The green jack on the back of a computer is specifically designated for Audio Out, typically used for connecting headphones or speakers to output sound from the computer.
