00:00:00.160 --> 00:00:01.700
Welcome to this lecture on servers

2
00:00:01.720 --> 00:00:04.020
and their importance
in mobile app development.

3
00:00:04.040 --> 00:00:04.810
In this lecture,

4
00:00:04.840 --> 00:00:08.460
we will explain what a server is,
how it works, and why it is important

5
00:00:08.490 --> 00:00:11.980
to have mobile applications
connected to servers.

6
00:00:12.010 --> 00:00:13.780
Let's start with basics.

7
00:00:13.810 --> 00:00:17.700
A server is a computer,
program or device that provides

8
00:00:17.720 --> 00:00:23.420
functionality or services to other
programs or devices known as clients.

9
00:00:23.450 --> 00:00:27.900
In simpler terms, a server is a computer
that responds to requests from other

10
00:00:27.920 --> 00:00:30.193
computers, devices, or programs

11
00:00:30.393 --> 00:00:32.980
by providing data or performing tasks.

12
00:00:33.000 --> 00:00:34.820
When we talk about mobile apps,

13
00:00:34.850 --> 00:00:39.460
a server is crucial to their functioning
mobile apps are designed to perform specific

14
00:00:39.490 --> 00:00:42.780
tasks or provide certain
functionalities to users.

15
00:00:42.810 --> 00:00:45.380
These tasks often require data or

16
00:00:45.410 --> 00:00:49.540
information that is not stored
on the mobile device itself.

17
00:00:49.570 --> 00:00:51.460
This is where servers come in.

18
00:00:51.490 --> 00:00:53.780
A server can store large amounts of data

19
00:00:53.810 --> 00:00:57.900
and provide access to this data
to mobile apps when they need it.

20
00:00:57.930 --> 00:01:02.060
For example, when you opened a weather
app, it needs to communicate with a server

21
00:01:02.090 --> 00:01:05.260
to get the current weather
conditions for your location.

22
00:01:05.290 --> 00:01:09.820
Similarly, when you open a social media
app, it needs to communicate with a server

23
00:01:09.850 --> 00:01:12.540
to get the latest updates
from your friends.

24
00:01:12.570 --> 00:01:13.679
Without a server,

25
00:01:13.879 --> 00:01:16.290
mobile apps would be limited to the data

26
00:01:16.320 --> 00:01:18.352
and functionality that is stored

27
00:01:18.552 --> 00:01:20.130
on the mobile device itself.

28
00:01:20.160 --> 00:01:22.620
This would severely limit the capabilities

29
00:01:22.650 --> 00:01:25.170
of mobile apps and make them

30
00:01:25.370 --> 00:01:27.420
far less useful to users.

31
00:01:27.450 --> 00:01:29.820
Now that we understand what a server is

32
00:01:29.850 --> 00:01:33.700
and why it's important,
let's take a closer look at how it works.

33
00:01:33.730 --> 00:01:35.780
When a mobile app needs to communicate

34
00:01:35.810 --> 00:01:39.570
with a server, it sends a request
to the server over the Internet.

35
00:01:39.600 --> 00:01:41.620
This request contains information about

36
00:01:41.650 --> 00:01:45.660
what the app needs from the server,
such as data or functionality.

37
00:01:45.690 --> 00:01:48.290
The server then receives this request,

38
00:01:48.320 --> 00:01:53.020
processes it, and sends back the response
back to the mobile application.

39
00:01:53.050 --> 00:01:57.900
This response contains the requested data
or performs the requested functionality.

40
00:01:57.930 --> 00:02:00.290
This communication between the mobile app

41
00:02:00.320 --> 00:02:03.265
and the server is often referred to as an

42
00:02:03.465 --> 00:02:06.210
API or application programming interface.

43
00:02:06.240 --> 00:02:11.450
And we're going to talk about what APIs
are in the next lecture in more details.

44
00:02:11.480 --> 00:02:16.580
So in conclusion, servers are a crucial
component of mobile app development.

45
00:02:16.610 --> 00:02:20.700
They allow mobile apps to access large
amounts of data and provide functionality

46
00:02:20.730 --> 00:02:23.820
that is not possible
on the mobile device itself.

47
00:02:23.850 --> 00:02:27.020
Without servers,
mobile apps would be severely limited

48
00:02:27.050 --> 00:02:30.220
in their capabilities
and usefulness to users.

49
00:02:30.240 --> 00:02:32.060
Thank you for listening to this lecture

50
00:02:32.080 --> 00:02:34.700
on servers and their importance
in mobile app development.

51
00:02:34.720 --> 00:02:35.960
I'll see you in the next video.
