Input and Output devices and write at least 2 points for each requirement:
Ques. 1)
Input Devices:
Device
Barcode scanner
QR code scanner
2D and 3D scanners
Digital camera
Benefits/Drawbacks
Uses
Benefits: They can be used to calculate the prices and
get out of the problem of asking employees manually,
They can also be used for calculating total by inserting
the barcode of multiple objects and calculating the total
without the use of a calculator
1ST Use: Shops can use the barcodes to list the prices of
certain items for ex clothes, food, canned goods.
Drawback: If the barcode of certain items is worn out
then it’s impossible to calculate the price of it, You need
barcode scanners to find the prices, so buying the
scanners are very costly.
2nd Use: They can be used to track and manage certain
orders, for ex when we order an item from daraz it always
comes with a barcode on it to figure what item it is
Benefits: They are very efficient, they reduce errors
produced by humans, they also save money by the
prevention of production of paper for ex: menus, letters,
etc., They enhance customer services, they also can
provide analytical feedbacks
1ST Use: Restaurants can use QR Codes for their menus,
and can also use the codes for getting feedbacks from the
customers.
Drawback: Hackers could mislead people into
installing viruses into their devices, Worn-Out QR codes
are unable to work, They also need consistent
maintenance checkups unlike normal papers.
2nd Use: QR codes can be used to redirect people to
certain links very easily despite typing the link manually
into the search bar, People can also avail certain offers
given by certain companies.
Benefits: 2d and 3d scanners can be used to input
information on certain objects or papers into the
computer, And they are high in flexibility meaning they
can be used to insert information of basically anything
1ST Use: Scanners are used to scan barcodes and QR codes
of certain items to find out their prices
Drawback: They are very high in cost, they are limited
to only 2D and 3D and since 1D is more common they
can’t be used on them.
2nd Use: They are used to finding out the what item is
placed inside the package by scanning their barcodes
Benefits: They can be used to store certain images into
the micro SD’s which can be later transferred inside the
computer, Most Digital cameras or you can say all the
cameras are high quality and can take pictures very well
1ST Use: They are used to take pictures on memorable
occasions of a family
Drawback: They are extremely fragile meaning that
once they are dropped they can break easily, but not
most of the cameras are that fragile, If the micro SD is
damaged (Which is common) the data and all the images
are lost. Which is why people have switched to Mobiles
2nd Use: Pictures can be transferred to laptops and
computers meaning that they can be framed very easily

the computer
Benefits: They can be used and operated by any object
for example an stylus pencil like in Samsung phones use
resistive touch screen to make the pencil work, They are
also very durable since there are two screens working to
make the resistive technology work.
2nd Use: They are also used in gaming fields just like the
Optical Mouse to communicate with your friends while
gaming.
1ST Use: They are used in certain malls and shops to
provide feedback and to order stuff in restaurants just like
