Input and Output Questions and Answers

Q: Each program can have ___________.

Correct answer: All of TheseAll three are ordinary parts of a program. Input is the data it operates on, output is what it produces, and functions are how its instructions are organised into reusable units.The word "can" is doing the work: none is compulsory. A program may compute a constant result with no input, or produce no output at all, or be written as one block without functions. The option is correct because it asserts possibility rather than necessity.

Q: The wheel located between the two standard buttons on a mouse is used to ____

Correct answer: ScrollThe wheel between the two buttons rolls the view up and down a document or page. Clicking and selecting are done with the buttons on either side of it.

Q: The unattended interactive information systems such as automatic teller machine or ATM is called as _________

Correct answer: KiosksA kiosk is an unattended interactive terminal placed in a public space - a cash machine, a ticket machine, an information point, a self-service checkout.Its design follows from being unattended: a simplified interface for users with no training, hardened input devices such as touch screens and sealed keypads, and physical security for whatever it dispenses. The other options are not words. The term is borrowed from the small structures such machines were first placed in.

Q: Which of the following is not a point-and-draw device?

Correct answer: KeypadA keypad has discrete keys and enters characters or digits; it cannot indicate an arbitrary position on the screen or trace a path, which is what point-and-draw means.The other three all can. A mouse and a trackball report continuous movement, and a touch screen reports the position touched directly. Arrow keys move a cursor in fixed steps, which is why they serve as a poor substitute for a pointing device rather than as one.

Q: The term used to define all input and output devices in a computer system is ____

Correct answer: HardwareHardware is the collective term for the physical parts of a computer, which includes every input and output device. Software is the set of programs, and a monitor is one output device rather than the class.

Q: What does GUI stand for?

Correct answer: Graphical User InterfaceA graphical user interface presents the system as windows, icons, menus and a pointer, so that operations are performed by direct manipulation rather than by typing commands.The contrast is with the command line interface, which requires the user to know and type the command names. The graphical form is what made computers usable without training, and the pointing devices in this topic - mouse, trackball, touch screen - exist to serve it.

Q: The quality and performance of a monitor depends on

Correct answer: Video Card, Resolution, and Refresh RateThese three between them determine what the user sees. The video card generates the signal and bounds what the monitor can be driven to display; resolution sets the number of pixels and hence the detail; refresh rate sets how often the image is redrawn and therefore the smoothness of motion.Size affects how large the image appears but not its quality - a large screen at low resolution simply shows the same detail bigger, with coarser pixels, which is why the options including size are the weaker set.

Q: The most widely used input device is the ____

Correct answer: KeyboardThe keyboard is the input device present on virtually every computer and used for nearly all text and command entry. A mouse is almost as common but points rather than enters data; a modem is a communication device and a monitor is an output device.

Q: These devices provide a means of communication between a computer and outer world.

Correct answer: I/OInput and output devices are the interface between the machine and everything outside it - users, other machines, and the physical world.Without them a computer could compute but neither receive a problem nor report an answer. They are also called peripherals, because they surround the processor and memory rather than forming part of them. Storage devices are a special case, communicating with the machine's own long-term memory rather than with the world.

A.Video Card, Refresh Rate, and Size
B.Size, Video Card. and Resolution
C.Video Card, Resolution, and Refresh Rate

A.I/O
B.Storage
C.Compact
D.Drivers

Answer: A

Correct answer: I/O

Input and output devices are the interface between the machine and everything outside it - users, other machines, and the physical world.

Without them a computer could compute but neither receive a problem nor report an answer. They are also called peripherals, because they surround the processor and memory rather than forming part of them.
