peripheral device, also known as peripheral, computer peripheral, input-output device, or input/output device, any of various devices (including sensors) used to enter information and instructions into a computer for storage or processing and to deliver the processed data to a human operator or, in some cases, a machine controlled by the computer. Such devices make up the peripheral equipment of modern digital computer systems.
Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices (which partake of the characteristics of the first two). An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer. An output device reverses the process, translating the digitized signals into a form intelligible to the user. At one time punched-card and paper-tape readers were extensively used for inputting, but these have now been supplanted by more efficient devices.
Computer – Hardware
Hardware represents the physical and tangible components of a computer, i.e. the components that can be seen and touched.
Examples of Hardware are the following −
Input devices − keyboard, mouse, etc.
Output devices − printer, monitor, etc.
Secondary storage devices − Hard disk, CD, DVD, etc.
Internal components − RAM,CPU, motherboard, etc.
INPUT AND OUTPUT DEVICES OF COMPUTER Input Devices A device that can be used to insert data into a computer system is called as input device. It allows people to supply information to computers without any input devices, a computer would only be a display device and not allow users to interact with it, Examples of input devices include keyboards, mouse, scanners, digital cameras and Light pen, joysticks, Touch-screen, OMR, OBR,OCR. Keyboard Most common and very popular input device is keyboard. The keyboard helps in inputting the data to the computer. The layout of the keyboard is like that of traditional typewriter, although there are some additional keys provided for performing some additional functions. Keyboard is of two sizes 84 keys or 101/102 keys, but now 104 keys or 108 keys keyboard is also available for Windows and Internet. Mouse Mouse is most popular Pointing device. It is a very famous cursor-control device. It is a small palm size box with a round ball at its base which senses the movement of mouse and sends corresponding signals to CPU on pressing the buttons. Generally it has two buttons called left and right button and scroll bar is present at the mid. Mouse can be used to control the position of cursor on screen, but it cannot be used to enter text into the computer.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. In computing,
I/O (Input / Output) is the
communication between an information
processing system , such as a computer ,
and the outside world , possibly a human
or another information processing system.
Inputs are the signals or data received
by the system.
Outputs are the signals or data sent
from it.
3. An input device is a hardware or
peripheral device used to send data to a
computer. An input device allows users to
communicate and feed instructions and data
to computers for processing , display , storage
and /or transmission.
5. Microphone
Magnetic Ink Card Reader(MICR)
Optical Character Reader(OCR)
Bar Code Reader
Optical Mark Reader(OMR)
6. Keyboard is the most common and very
popular input device which helps to
input data to the computer . The layout
of the keyboard is like that of
traditional typewriter , although there are
some additional keys provided for
performing additional functions.
10. Keyboards are of two sizes 84 keys
or 101/102 keys , but now keyboards
with 104 keys or 108 keys are also
available for Windows and Internet .
Keys are further divided into five
keywords
11. Typing Keys
These keys include the letter keys (A-Z) and digit
keys (09) which generally give the same layout as
that of typewriters.
Numeric Keypad
It is used to enter the numeric data or cursor
movement. Generally, it consists of a set of 17 keys
that are laid out in the same configuration used by
most adding machines and calculators.
12. Function Keys
The twelve function keys are present on the keyboard
which are arranged in a row at the top of the
keyboard. Each function key has a unique meaning
and is used for some specific purpose.
Control keys
These keys provide cursor and screen control. It
includes four directional arrow keys. Control keys also
include Home, End, Insert, Delete, Page Up, Page
Down, Control(Ctrl), Alternate(Alt), Escape(Esc).
13. Special Purpose Keys
Keyboard also contains some special purpose keys
such as Enter, Shift, Caps Lock, Num Lock, Space bar,
Tab, and Print Screen.
14. Mouse is the most popular pointing device .
It is a very famous cursor – control device
having a small palm size box with a round
ball at its base , which senses the movement
of the mouse and sends corresponding
signals to the CPU when the mouse
buttons are pressed.
Generally, it has two buttons called the left and the
right button and a wheel is present between the
buttons. A mouse can be used to control the
position of the cursor on the screen, but it cannot
be used to enter text into the computer.
18. Joystick is also a pointing device , which
is used to move the cursor position on
a monitor screen . It is a stick having a
spherical ball at its both lower and
upper ends. The lower spherical ball
moves in a socket. The joystick can be
moved in all four directions.
The function of the joystick is similar to that of
a mouse. It is mainly used in Computer Aided
Designing (CAD) and playing computer
games.
20. Light pen is a pointing device similar to
a pen . It is used to select a displayed
menu item or draw pictures on the
monitor screen . It consists of a photocell
and an optical system placed in a small
tube.
the pen button is pressed, its photocell sensing
element detects the screen location and sends
the corresponding signal to the CPU.
22. Track ball is an input device that is mostly used
in notebook or laptop computer, instead of a
mouse. This is a ball which is half inserted and
by moving fingers on the ball, the pointer can
be moved.
Since the whole device is not moved, a track
ball requires less space than a mouse. A track
ball comes in various shapes like a ball, a
button, or a square.
23.
24. Scanner is an input device, which works more
like a photocopy machine. It is used when
some information is available on paper and it is
to be transferred to the hard disk of the
computer for further manipulation.
Scanner captures images from the source which
are then converted into a digital form that can
be stored on the disk. These images can be
edited before they are printed.
25.
26. Microphone is an input device to input sound
that is then stored in a digital form.
Microphones are used in many applications
such as telephones, hearing aids, public
address systems for concert halls and public
events, motion picture production, live and
recorded audio engineering, sound recording,
two-way radios, megaphones, radio and
television broadcasting.
We can also calls as a MIC
27.
28. MICR input device is generally used in banks
as there are large number of cheques to be
processed every day. The bank's code number
and cheque number are printed on the cheques
with a special type of ink that contains particles
of magnetic material that are machine readable.
This reading process is called Magnetic Ink
Character Recognition (MICR). The main
advantages of MICR is that it is fast and less
error prone.
30. It can also calls as a OCR
It is used to read a printed text.
OCR scans the text optically, character by
character, converts them into a machine
readable code, and stores the text on the
system memory.
32. Bar Code Reader is a device used for reading
bar coded data (data in the form of light and
dark lines). Bar coded data is generally used in
labelling goods, numbering the books, etc. It
may be a handheld scanner or may be
embedded in a stationary scanner.
Bar Code Reader scans a bar code image,
converts it into an alphanumeric value, which
is then fed to the computer that the bar code
reader is connected to.
34. It can also calls as OMR
OMR is a special type of optical
scanner used to recognize the type
of mark made by pen or pencil . It
is used where one out of a few
alternatives is to be selected and
marked.
36. An output device is any device used to
send data from a computer to another
device or user . Most computer data output
that is meant for humans is in the form of
audio or video. Thus, most output devices
used by humans are in these categories.
Examples include monitors, projectors, speakers,
headphones and printers.
38. Monitors, commonly called as Visual Display
Unit (VDU), are the main output device of a
computer. It forms images from tiny dots,
called pixels that are arranged in a rectangular
form. The sharpness of the image depends
upon the number of pixels.
There are two kinds of viewing screen used for
monitors.
Cathode-Ray Tube (CRT)
Flat-Panel Display
39. The CRT display is made up of small picture
elements called pixels. The smaller the pixels,
the better the image clarity or resolution.
A finite number of characters can be displayed
on a screen at once.
The screen can be divided into a series of
character boxes.
Most screens are capable of displaying 80
characters of data horizontally and 25 lines
vertically.
42. The flat-panel display refers to a class of
video devices that have reduced volume,
weight and power requirement in comparison
to the CRT. You can hang them on walls or
wear them on your wrists.
Current uses of flat-panel displays include
calculators, video games, monitors, laptop
computer, and graphics display.
44. The flat-panel display is divided into two
categories −
Emissive Displays
Emissive displays are devices that convert
electrical energy into light. For example, plasma
panel and LED (Light-Emitting Diodes).
Non-Emissive Displays
Non-emissive displays use optical effects to
convert sunlight or light from some other source
into graphics patterns. For example, LCD
(Liquid-Crystal Device).
45. Printer is an output device
It is used to print information on paper.
There are two types of printers −
Impact Printers
Non-Impact Printers
46. Impact printers print the characters by striking
them on the ribbon, which is then pressed on
the paper.
Characeristics of impact printers
Very low consumable costs
Very noisy
Useful for bulk printing due to low cost
There is physical contact with the paper to
produce an image
48. Non-impact printers print the characters without
using the ribbon. These printers print a complete
page at a time, thus they are also called as Page
Printers.
Characeristics of non-impact printers
Faster than impact printers
They are not noisy
High quality
Supports many fonts and different character size
51. A projector is a device that uses light and
lenses to take an image and project a magnified
image onto a larger screen or wall. Projectors
can magnify still or moving images depending
on how they are built. The image must be
shone through a sealed tube or frame when
passing through the lenses to maintain focus.
One of the best example is movie theatres
52.
53. Speakers are one of the most common output
devices used with computer systems. Some
speakers are designed to work specifically with
computers, while others can be hooked up to
any type of sound system. Regardless of their
design, the purpose of speakers is to produce
audio output that can be heard by the listener.
Speakers are transducers that convert
electromagnetic waves into sound waves. The
speakers receive audio input from a device such
as a computer or an audio receiver. This input
may be either in analog or digital form.
54.
55. Headphones are small speakers that can be
worn in or around your ears.
Traditional headphones have two ear cups
attached by a band that is placed over your
head. Smaller headphones, often called
earbuds or earphones, are placed inside the
outer part of your ear canal.
