Computer Hardware Devices

A Cathode Ray Tube (CRT) is a vacuum tube technology used in traditional monitors and televisions to display images. It is not found in CPUs, printers, or scanners.

Input devices send data TO the computer, while output devices receive data FROM the computer. A scanner captures images/documents and sends them to the computer, making it an input device. Monitors, printers, and speakers all output information from the computer to the user.

EIDE (Enhanced Integrated Drive Electronics) cables connect motherboards to storage devices like hard disk drives. Floppy drives use FDD cables, while sound cards and video cards use different interface connections.

CD is the odd one out. Keyboard, Mouse, and Monitor are all computer input/output devices that are essential components. A CD is a storage medium - not a peripheral device but rather a removable data carrier.

The iPod touch was one of Apple's iPod models. The question appears to be testing recognition of Apple product lines and the 'touch' designation specifically belonged to the iPod family, not Mac, iTunes, or iPhone.

In a word processing system, peripheral devices can include floppy disk drives, magnetic card readers, and cathode ray tube (CRT) monitors for display. Since all listed items serve as valid peripherals, the correct choice is all of these.

The joystick was originally developed for controlling aircraft and was first used in aviation during World War I. It allowed pilots to maneuver aircraft more effectively than previous control mechanisms. Later, this technology was adapted for video games and computer interfaces.

Refresh rate is the number of times per second a display screen updates its image, measured in Hertz (Hz). A 60Hz monitor refreshes 60 times each second, showing 60 frames per second. Higher refresh rates result in smoother motion and reduced eye fatigue. The 'screen saver' option (A) is unrelated to refresh rate - it's a power-saving feature.

A skimmer is a malicious device illegally attached to ATMs, card readers, or payment terminals to capture credit and debit card information. When a victim slides their card through the compromised reader, the skimmer records the card's magnetic strip data, which criminals then use to create counterfeit cards or make fraudulent purchases.

Douglas Engelbart invented the computer mouse in 1964 while working at Stanford Research Institute. It was patented in 1970 and revolutionized human-computer interaction by making personal computers much more accessible.

FMD (Fluorescent Multi-Layer Disc) was an optical disc format that used multiple fluorescent layers to achieve higher storage capacity than conventional DVDs. The technology relied on fluorescent materials rather than reflective layers like traditional optical media.

LCD monitors are commonly referred to as TFT (Thin-Film Transistor) displays because TFT technology is used to improve image quality and response times in LCD panels. TFT is an active-matrix LCD technology. The other options are different display technologies: DLP uses micromirrors, Plasma uses gas cells, and CRT uses electron beams on phosphor coatings.
