10 Questions
Explain the role of the I/O Subsystem in a computer and its significance in communication with the outside environment.
The I/O Subsystem of a computer provides an efficient mode of communication between the central system and the outside environment. It facilitates the interaction between the computer and peripheral devices, enabling data transfer and control.
What is the purpose of the Input Output Interface in a computer system?
The Input Output Interface provides a method for transferring information between internal storage and external I/O devices. It enables the connection and communication between peripherals and the central processing unit, resolving differences that exist between them.
List and briefly explain the most common input/output devices connected to a computer.
i) Monitor: Displays visual output from the computer. ii) Keyboard: Allows input of textual and command data. iii) Mouse: Enables user interaction through pointing and clicking. iv) Printer: Produces hard copy output. v) Magnetic tapes: Used for long-term data storage and retrieval.
What defines peripherals as being 'connected online' in the context of a computer system?
Peripherals that are under the direct control of the computer are said to be connected online. This means they are actively and directly linked to the central processing unit for communication and data transfer.
What are the major differences that the communication link aims to resolve between the central computer and each peripheral?
The communication link aims to resolve the differences between the central computer and each peripheral, such as the electromechanical and electromagnetic nature of peripherals, and their varying communication protocols and interfaces.
What is the purpose of the I/O Subsystem in a computer?
The purpose of the I/O Subsystem is to provide an efficient mode of communication between the central system and the outside environment.
List five common input/output devices found in a computer system.
Monitor, keyboard, mouse, printer, and magnetic tapes.
What is the role of the Input Output Interface in a computer system?
The Input Output Interface provides a method for transferring information between internal storage and external I/O devices.
What is the significance of having special communication links for peripherals connected to a computer?
Special communication links are needed to interface peripherals with the central processing unit, resolving differences that exist between the central computer and each peripheral.
What are the major differences between peripherals and the central computer?
One major difference is that peripherals are electromechanical and electromagnetic devices.
