Welcome to this lecture on servers
and their importance in mobile app development.
In this lecture,
we will explain what a server is, how it works, and why it is important
to have mobile applications connected to servers.
Let's start with basics.
A server is a computer, program or device that provides
functionality or services to other programs or devices known as clients.
In simpler terms, a server is a computer that responds to requests from other
computers, devices, or programs
by providing data or performing tasks.
When we talk about mobile apps,
a server is crucial to their functioning mobile apps are designed to perform specific
tasks or provide certain functionalities to users.
These tasks often require data or
information that is not stored on the mobile device itself.
This is where servers come in.
A server can store large amounts of data
and provide access to this data to mobile apps when they need it.
For example, when you opened a weather app, it needs to communicate with a server
to get the current weather conditions for your location.
Similarly, when you open a social media app, it needs to communicate with a server
to get the latest updates from your friends.
Without a server,
mobile apps would be limited to the data
and functionality that is stored
on the mobile device itself.
This would severely limit the capabilities
of mobile apps and make them
far less useful to users.
Now that we understand what a server is
and why it's important, let's take a closer look at how it works.
When a mobile app needs to communicate
with a server, it sends a request to the server over the Internet.
This request contains information about
what the app needs from the server, such as data or functionality.
The server then receives this request,
processes it, and sends back the response back to the mobile application.
This response contains the requested data or performs the requested functionality.
This communication between the mobile app
and the server is often referred to as an
API or application programming interface.
And we're going to talk about what APIs are in the next lecture in more details.
So in conclusion, servers are a crucial component of mobile app development.
They allow mobile apps to access large amounts of data and provide functionality
that is not possible on the mobile device itself.
Without servers, mobile apps would be severely limited
in their capabilities and usefulness to users.
Thank you for listening to this lecture
on servers and their importance in mobile app development.
I'll see you in the next video.
