Overview of Computer Hardware and Software Components

A keyboard is an input device that allows users to input text and commands by pressing keys.
A mouse is an input device that enables users to move a cursor on the screen and interact with graphical user interfaces through clicking and scrolling.
A display, such as a monitor or screen, is an output device that presents visual information generated by the computer to the user.
A printer is an output device that produces hard copies of digital documents or images on paper or other media.
A scanner is an input device that converts physical documents or images into digital format, allowing them to be stored, edited, or transmitted by the computer.
Speakers are output devices that generate sound or audio output, allowing users to listen to music, multimedia, or system-generated audio.
Storage devices, such as hard disk drives (HDDs), solid-state drives (SSDs), and optical drives, enable reading from and writing to various types of storage media, such as hard disks, solid-state memory, CDs, DVDs, and Blu-ray discs.
Network interfaces, such as Ethernet adapters or Wi-Fi cards, allow computers to connect to local area networks (LANs) or the internet, enabling data transmission and communication with other devices.
The kernel I/O subsystem, also referred to as the I/O stack or I/O manager, is a component of an operating system's kernel that handles the management and coordination of input/output operations.
Transforming I/O request to hardware refers to the process of converting or modifying an input/output (I/O) request before it is sent to a hardware device for execution.
Streams refer to a sequence of data elements that are accessed or processed sequentially, usually in a continuous flow, and provide an interface for reading or writing data from or to different sources, such as files, network connections, or memory buffers.
Streams enable efficient handling of large amounts of data by processing it in smaller, manageable chunks instead of loading the entire dataset into memory at once.
