External devices and peripherals are non-essential components attached to computers to expand their functionality. Input devices like keyboards and mice provide data to computers, while output devices like monitors, printers and speakers share the computer's processed information. Storage devices both internal and external are used to permanently or temporarily save files and data. A history of external storage highlighted early hard drives the size of refrigerators and the introduction of USB technology that enabled smaller portable drives. Common input/output and storage peripherals along with their technologies were also examined.

This section of the memory is also referred to as backup storage.
The storage capacity of primary storage is not sufficient to store the large volume so secondary storage.
Secondary storage also know as external memory or auxiliary storage not directly accessible by the CPU.
In MS-Dos (Disk Operating System) There are two types of Basic dos commands they are internal dos commands and external dos commands which are used separately to perform specific task or operation. Internal dos commands are those commands which are included in command processor (command.com). Internal dos commands are built in command.com file and while the computer has been booted this file or commands are loaded in the computer memory and you can use this basic dos commands while computer is ON.
An output device is any peripheral that receives data from a computer, usually for display, projection, or physical reproduction. For example, the image shows an inkjet printer, an output device that can make a hard copy of any information shown on your monitor.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
3. Introduction: External device and peripherals
• External device:-
A computer interacts with the external environment via the input-output (I/O)
devices attached to it. Input device is used for providing data and instructions to
the computer. After processing the input data, computer provides output to the
user via the output device.
• Peripherals:-
The I/O devices that are attached, externally, to the computer machine are also
called peripheral devices.
The term peripheral is used to describe those devices that are optional in
nature, as opposed to hardware that is either demanded or always required in
principle.

4. History
• The very earliest hard drives were external for all intents and purposes.
• This is because they were not mounted within the computer frame.
• These devices debuted in the late 1950s, could store 5MB of data and shipped
with the first commercially available IBM systems.
• Almost 30 years after the debut of those systems, IBM brought out the first
gigabyte drive.
• This device was the size of a household refrigerator, and was a separate unit
from the computer’s..
• Between the debut of the personal computer and the release of what a modern
consumer might recognize as an external hard drive, there were several
innovations.
• However, most of these were strictly for internal drives, as the need for an
external drive was not particularly great with early systems.
06/29/14 4
5. History
• One of the first systems to make use of an external hard drive was Apple.
• Apple introduced the ProFile in 1983.
• Their computers often had drive bays that were difficult to access, and some had no
hard drive within them at all.
• This hard drive offered 5MB of disk space, though a 10MB was offered later as an
upgrade.
• The year was 1998, and a revolution was brewing in the computer industry. This was
the time when the USB interface was introduced to computers.
• This ground-breaking technology enabled any type of device to connect directly with a
computer from the outside, using the same type of interface.
• Previously, hard drives made use of a 40-pin connector and a power cable .
• This single technology allowed different external hard drive designs to proliferate. It
also enabled the birth of other removable media, such as the flash drive.
• The first external USB drives were bulky things, due to the technology available in
1998.

6. About External Device
External storage comprises devices that temporarily store
information for transporting citation needed from computer to
computer. Such devices are not permanently fixed inside a
computer.
External drives are connected to the computer with a cable
plugged into a suitable interface such as an USB port. Data then
passes back and forth across the interface.
The main advantage of external drives is that they are portable
and so data is easily moved from one location to another. External
drives also allow safe backup of internally stored data.
The main disadvantage compared to an internal drive is data
transfer is slower and they also take up space around the
computer. Constant plugging in and out can also physically wear
out the port over time.

7. About Peripherals
A peripheral device:
A hardware component that is attached to a computer in order to expand its abilities and
perform additional features.
It allows the user to interact with the computer by inputting commands, viewing the screen as
well as printing out documents and pictures.
It is “additional but not essential”, they are not part of the essential computer as are the
processor, and the memory.
Some are mounted in the same case with the main part of the computer as are the hard disk
drive or CD-ROM drive.
Other peripherals are outside the computer case, e.g. the printer and image scanner, attached by
a wired or wireless connection.
06/29/14 7
8. About Peripherals
A peripheral can be an internal or external device.
Computer peripherals, or peripheral devices, are sometimes called "I/O devices" because
they provide input (e.g. a keyboard / mouse) and output (e.g. a monitor / printer) for the
computer.
Some peripherals, e.g. external hard drives, provide both input and output for the computer
Most devices, whether peripheral or not, require a programme called a device driver that
acts as a translator, converting general commands from an application into specific
commands that the device understands.
