This type of scanner has a specialized mechanism that allows it to hold and scan individual slides, ensuring high-quality scanning of these small and transparent images. Drum scanners, flatbed scanners, and sheet-fed scanners are not specifically designed for scanning photo slides, although they can be used for other types of scanning tasks.

The output of a blue color wire in an SMPS is -12v DC. This means that when the blue wire is connected to a device, it will provide a direct current (DC) voltage of -12 volts. The negative sign indicates that the voltage is negative relative to the reference point. This voltage level may be used to power specific components or circuits that require a -12v DC supply.

The control section of the CPU is responsible for selecting and interpreting program instructions. It ensures that the instructions are executed correctly by coordinating the activities of other sections of the CPU, such as the ALU and memory. It also checks whether the instructions have been executed or not, ensuring the proper flow of the program. Therefore, the control section is the correct answer to the question.

The ATX power connector is used to supply power to the motherboard. ATX stands for Advanced Technology Extended, and it is a standard power supply design used in most modern computers. It provides the necessary power to the motherboard and other components, ensuring proper functioning of the system. The other options listed, PCI, AGP, and PS/2, are not power connectors but rather refer to different types of expansion slots or ports on the motherboard.

The CMOS chip is responsible for storing the time and settings of a system. CMOS stands for Complementary Metal-Oxide-Semiconductor, and it is a type of memory technology used in computers. It is powered by a small battery, allowing it to retain information even when the computer is turned off. The CMOS chip holds important system configuration data, such as the date and time, boot order, and hardware settings. This information is essential for the proper functioning of the computer and is accessed by the BIOS (Basic Input/Output System) during the booting process.

A nibble is a unit of digital information that consists of 4 bits. It is half of a byte, which is composed of 8 bits. Therefore, 1 nibble is equivalent to 4 bits.

A DIMM package typically contains 168 pins. DIMM stands for Dual In-Line Memory Module, which is a type of memory module used in computers. The number of pins is important as it determines the compatibility and connection of the module to the motherboard. 168 pins is a common configuration for DIMM packages, allowing for efficient data transfer between the memory module and the system.

The correct answer is "sheet fed". This is because a sheet fed scanner is specifically designed to scan large individual sheets of paper. It is able to feed one sheet at a time and scan it quickly and efficiently. This type of scanner is commonly used in offices and other settings where large documents need to be scanned regularly.

An external modem requires an AC adapter to get powered on because it needs an external power source to function. AC adapters convert the alternating current from a wall outlet into the direct current needed to power the modem. This allows the modem to receive power and operate properly. Ethernet adapters, DC adapters, and data cables are not used to power on an external modem.
