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.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

3. KEYBOARD
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.
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.
The keys on the keyboard are as follows −
Typing Keys
These keys include the letter keys (A-Z) and digit keys (09) which generally give
the same layout as that of typewriters.
2 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.
3 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.
4. 4 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).
5 Special Purpose Keys
Keyboard also contains some special purpose keys such as Enter, Shift, Caps
Lock, Num Lock, Space bar, Tab, and Print Screen.
5. Mouse
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.
Advantages
Easy to use
Not very expensive
Moves the cursor faster
than the arrow keys of the keyboard.
6. Joystick
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.
7. Light Pen
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.
When the tip of a light pen is moved over the monitor
screen and the pen button is pressed, its photocell
sensing element detects the screen location and sends
the corresponding signal to the CPU.
8. Track Ball
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.
9. Scanner
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.
10. Digitizer
Digitizer is an input device which converts analog
information into digital form. Digitizer can convert a signal
from the television or camera into a series of numbers that
could be stored in a computer. They can be used by the
computer to create a picture of whatever the camera had
been pointed at.
Digitizer is also known as Tablet or Graphics Tablet as it
converts graphics and pictorial data into binary inputs. A
graphic tablet as digitizer is used for fine works of
drawing and image manipulation applications
11. Magnetic Ink Card Reader (MICR)
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.
`
12. Optical Character Reader (OCR)
OCR is an input device 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.
13. Bar Code Readers
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.
14. Optical Mark Reader (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.
It is specially used for checking the answer
sheets of examinations having multiple choice
questions.
15. Touch screen
It is the display screen of a device such as a
smartphone, tablet, etc., that allows users to interact
or provide inputs to the device by using their finger.
Today, most of the electronic devices come with
touchscreen as an alternative to a mouse for
navigating a graphical user interface. For example,
by touching, you can unlock your phone, open emails,
open files, play videos, etc. Besides this, it is used in
lots of devices such as Camera, Car GPS, Fitness
machine, etc.
