The document discusses the importance of computers in daily life and how they have become essential tools in homes and businesses. It notes how computers have led to the digitization and electronic processing of transactions across many fields like education, health, and more. Computers are also described as important sources of knowledge since they can access the internet to find written, audio, and visual information online. The current era is characterized as the information age due to computers becoming basic elements of human life.

1. COMPUTERS IN
OUR DAILY LIFE

2. The computer has brought about a
quantum leap in our daily life, and
dependence on computer has
increased to occupy an essential
position in every home and every
company. All transactions in various
fields have been shifted to be
digitalized or to be electronic, as
education depends on computers and
technological development to improve
its performance and results, as well as
health fields and other fields.

3. Computer has become one of the most
important sources of knowledge, as
the computer is connected to the
Internet and browsing all sources of
science and knowledge, whether
written, audio or visual, and they can
be downloaded onto the computer and
find it at any time. The current century
is the age of information revolution, as
the computer has turned into a basic
element of life for humans.

4. Benefits of Mobile
Applications in the
Everyday Life
2.1 Apps: Their relevance to day-today activities

5. Applications have made the lives easiest, always there for the rescue to save time, effort, and dependencies.
You want a few transactions; financial apps save you from the bank visit. In need of groceries, an app lets you
shop from home and get everything to your door.
Several segments have successfully launched applications and are looking forward to the betterment and
advancements. Here are a few subjects that made mobile applications the best thing.
• Communication
• Cooking
• Trivia
• Learning
• Entertainment
• Social Media
• Shopping
• Finance and Stocks Related
• Matrimony
And many more!

6. Some of the advantages that people opt for apps are:
• There are lots of apps focused on productivity like educational apps, exploring informative apps
that sharpen your skills and explore your interests.
• There are applications that make communication easiest. Voice calls, video calls, texting, and
conference calls give access to the connection with people in any corner of the world, all with a
mobile app.
• It ensures comfort to a greater extent. The convenience of shopping, selling, surveying, etc. It
eliminates the long queue waiting for ticket booking and gets a taxi at the doorsteps.
• Making and spending money is also made easiest with mobile applications with full security. It can
get you a loan, count interest, list you the finest policies, and pick for you the most financially
viable firms and other imperative data.
• We cannot miss out on an important idea – the idea of super apps. All the mentioned above welfare
or most of them when served right just with a single app, it’s a bunch of conveniences. There has
been a certain rise in the super apps for this reason and some more.
Applications have tremendously made life painless. Knowing the purpose and the exact way to use it
can serve utter satisfaction and the belonging experience. We are summing up these points for now
though there are rational reasons for the same.

7. The foundations of
networking: switches,
routers, and wireless
access points

8. Switches, routers, and wireless access points are the essential networking basics.
Through them, devices connected to your network can communicate with one
another and with other networks, like the Internet. Switches, routers, and wireless
access points perform very different functions in a network.
Switches allow devices on your network to
communicate with each other, as well as with
other networks, creating a network of shared
resources. Through information sharing and
resource allocation, switches save money and
increase productivity.

9. • A managed on-premises switch lets you
configure and monitor your LAN, giving
you tighter control of your network
traffic.
• Have a small IT team? A cloud-managed
switch can simplify your network
management. You get a simple user
interface, multisite full-stack
management, and automatic updates
delivered directly to the switch.

10. Routers connect multiple networks together. They also connect computers
on those networks to the Internet. Routers enable all networked computers to
share a single Internet connection, which saves money.
A router acts a dispatcher. It analyzes data being sent across a network,
chooses the best route for data to travel, and sends it on its way.
Routers connect your business to the world, protect information from security
threats, and can even decide which computers receive priority over others.
Beyond those basic networking functions, routers come with additional
features to make networking easier or more secure. Depending on your
security needs, for example, you can choose a router with a firewall, a
virtual private network (VPN), or an Internet Protocol (IP) communications
system.

11. Access Points
An access point allows devices to connect to the wireless network without cables.
A wireless network makes it easy to bring new devices online and provides flexible
support to mobile workers.
An access point acts like an amplifier for your network. While a router
provides the bandwidth, an access point extends that bandwidth so
that the network can support many devices, and those devices can
access the network from farther away.
But an access point does more than simply extend Wi-Fi. It can also
give useful data about the devices on the network, provide proactive
security, and serve many other practical purposes.
Access points support different IEEE standards. Each standard is an
amendment that was ratified over time. The standards operate on
varying frequencies, deliver different bandwidth, and support
different numbers of channels.

12. WIRELESS NETWORKING
To create your wireless network, you can choose between three types of
deployment: centralized deployment, converged deployment, and cloud-based
deployment.
1. Centralized deployment
The most common type of wireless network system, centralized
deployments are traditionally used in campuses where buildings and
networks are in close proximity. This deployment consolidates the
wireless network, which makes upgrades easier and facilitates
advanced wireless functionality. Controllers are based on-premises
and are installed in a centralized location.

13. 2. Converged deployment
For small campuses or branch offices, converged deployments offer
consistency in wireless and wired connections. This deployment
converges wired and wireless on one network device—an access
switch—and performs the dual role of both switch and wireless
controller.
3. Cloud-based deployment
This system uses the cloud to manage network devices deployed on-
premises at different locations. The solution requires Cisco Meraki
cloud-managed devices, which provide full visibility of the network
through their dashboards.
