Computer Hardware Devices

Scanner is an input device that scans documents and converts them into digital data.

Yes, both are the true options.

It is a device that reads data stored on a magnetic or optical disk and writes data onto the disk for storage.

Windows 2000 give the serial keys that have ability to support speech augmentation device.

Yes, all of the above use RISC.

The configuration of multiplexer is such that it provides one output at a time depending on the value of select signals from its inputs. This is the correct answer.

Low-power USB devices receive power through the USB cable itself, eliminating the need for separate power cables or external power supplies. This is one of USB's key advantages - it carries both data and power. The computer's power supply provides electricity through the USB port and cable.

The most critical factor is whether the mouse connector matches the available port on your computer (PS/2, USB, wireless). Driver software is usually generic or easily downloadable, cord length is flexible, and button count is a preference. Without physical compatibility, the mouse simply won't work with your system.

TWAIN is a standard interface for communication between scanners (and other imaging devices) and computer software. It's not a scanner component like a laser or cartridge, nor a general term like 'media'. TWAIN allows applications like Photoshop to acquire images directly from scanners without needing device-specific drivers.

A scanner is an INPUT device that captures images or documents and converts them to digital data. The other options (printer, flat screen, touch screen) are all output devices that display or produce information from the computer.

The mouse is the standard pointing device in Graphical User Interface (GUI) environments. It allows users to control the cursor position, click on icons, menus, and windows. While other pointing devices exist (trackball, joystick), the mouse became the de facto standard.

A digital scanner is an input peripheral device that captures images and documents, not a standalone computing device. Notebooks, cell phones, and PDAs are all computing devices with processors, memory, and the ability to execute programs independently.

The Basic Input/Output System (BIOS) is the firmware that manages essential peripherals like keyboard, screen, and disk drives during computer startup. It provides the fundamental interface between hardware and software, making 'Basic input/output system' the correct answer.

The cursor is the blinking indicator (usually a vertical line or underscore) that shows where text will be inserted on the screen. The mouse is a pointing device, logo refers to a brand symbol, hand and palm are cursor shapes but not the blinking insertion point itself. The cursor's blinking indicates the active text input position.
