DESCRIBE THE FOLLOWING TECHNICAL OBJECTS
1) 1) SMARTPHONE
A
smartphone is a cellular telephone with an integrated computer and other
features not originally associated with telephones, such as an operating system
(OS), web browsing and the ability to run
software applications.
Smartphones
are used by consumers and as part of a person's business or work. They provide
access to many mobile applications and computing functions, and have become
integral to everyday modern life.
Popular uses of smartphones
Common
ways smartphones are used include the following:
·
Email
and messaging. Email and
messaging applications can be loaded on a smartphone, letting users receive and
send messages from their phone.
·
Social
media. Many consumers
use smartphones to engage with friends, family and brands on social media. Social media platforms, such as
Facebook, Instagram, Twitter and LinkedIn, have mobile apps that users download from a
phone's app store. Smartphone apps make it possible for users to post personal
updates and photos while on the go.
·
Health
and wellness. Another common use for
smartphones is health and wellness tracking. For instance,
the Health app for Apple iOS tracks sleep behavior,
nutrition, body measurements, vital signs and mental health exercises.
·
Connecting
with other devices. Third-party wearable devices, such as smartwatches,
can connect with a smartphone to monitor an individual's health statistics,
such as heart rate and number of steps walked, and send that information to be
aggregated on the phone.
·
Mobile
payment. Digital wallet features let users save
credit card information on their phones to make mobile payments when buying
items. Apps such as Apple Pay also enable users
to pay other iOS users directly from their phones.
Important smartphone features
One of the most important elements of a smartphone is its
connection to an app store. These centralized portals let users search for and download
software applications to run on their phones. A typical app store offers
thousands of mobile apps for productivity, gaming, word processing,
note-taking, organization, social media and more.
The following are some other key smartphone features:
·
Internet access.
·
A web browser.
·
The ability to sync
more than one email account to a device.
·
Embedded memory.
·
A hardware or
software-based QWERTY keyboard.
·
Wireless
synchronization with other devices, such as laptop or desktop computers.
·
The ability to
download applications and run them independently.
·
Support for third-party
applications.
·
The ability to run
multiple applications concurrently.
·
Touchscreen.
·
Wi-Fi access.
·
A digital camera,
typically with video capability.
·
Gaming.
·
Unified messaging.
Smartphones also support accessories, including Bluetooth headphones, power charging
cables and extra speakers. The outer casing of most smartphones is fragile, so
users often buy screen protectors and cases for extra protection.
And, since smartphones run an OS and applications, vendors
usually provide software updates. Individual mobile apps in an
app store also provide updates that users can choose to install.
2) PEN DRIVE
A pen drive also known as a USB flash
drive, is a data storage device that includes flash memory with an integrated
USB interface. A typical USB drive is removable, rewritable, and smaller than
an optical disc, and usually weighs less than 30 g. A pen drive is a small yet
powerful device that can help you transfer files between devices easily and
quickly. It has revolutionized how we store and transfer data.
How
Does a Pen Drive Work?
·
Basic Components:
A USB drive consists of a USB connector, a flash memory chip, and a circuit
board all enclosed in a protective casing. The USB connector enables the pen
drive to connect with different devices, while the flash memory chip holds the
data.
·
Mechanism For Storing Data: Information
is saved in the flash memory chip by means of electrical charges. This
technique enables fast information access and retrieval, making pen drives
highly effective.
·
Process of Transferring Data:
When you insert a USB flash drive into a USB port, it
interacts with the operating system of your computer, enabling you to easily
move files by dragging and dropping them. The easy-to-use nature of this
process is a major factor driving the widespread use of pen drives.
TYPES

Advantages of Using Pen Drives
1) Data Transfer
2)
Backup Storage
3)
Bootable Devices
4) Media Storage
3) WASHING
MACHINE
A washing machine also know as a washer is a machine that washes dirty clothes. It contains a barrel into which the clothes are placed. This
barrel is filled with water, and then rotated very quickly by the use of a motor to make
the water remove dirt from the clothes. The user adds detergent (liquids or powders) to clean clothes more effectively.
Washing machines have ways to control how the
machine operates. Some of the possible controls are:
·
temperature of the
water
·
timer of the wash
cycle (before the soapy, dirty water is rinsed out)
·
number of wash cycles
before completing
Types of
washing machines
Washing
machines may be fully automatic or partly automatic.
Semi-Automatic Washing Machines
Semi-automatic
washing machines have separate sections for Dryer and Washer. These washing
machines are often termed as semi-manual as here you have to manually put
clothes into washer tub, put water & detergent according to your laundry
size, and once washing is finished, you again have to manually put washed
clothes for drying in dryer section. These are mostly cheaper machines.
Fully-Automatic Washing Machines
Fully-automatic
washing machines are easier to use. They have only one section for washing and
for spin-drying. Once you put clothes in a fully-automatic washing machine, it
automatically takes required quantity of water, detergent and
just with one click provided your washed & dry clothes.
Washing machines may load from
the top or the front.
