hey what's up guys I'm a and welcome to

this first video from the web dev cave

in this tutorial we'll talk about the

internet and the web what are they how

they work and how they are distinct from

each other but first let's go back to

the old days now this is not history

class don't be afraid but a little bit

of background will help us to understand

the evolution process down the road and

to better get the concepts in the 1960s

Advanced research projects agency also

known as arpa of the US Department of

Defense funded a research to develop

protocols to allow their computers to

interconnect with each other using

digital communication regardless the

geographical area therefore the first

Network a research network was created

the network was used for academic and

scientific purposes it started small

connecting a bunch of collected

University campuses research

institutions and companies the network

grew to a few hundred by the early 80s

at the same time other networks were

being created using other protocols

we'll cover networking and protocols in

much more details in other videos but

for now let's talk just about networks

and the internet as I said other

networks were being created using other

protocols networks such as x25 uset and

others but down the road a problem

raised people who were using these

networks wanted to interconnect with

each other by connecting the networks

together and in order to successfully

interconnect networks must use the exact

same protocols this problem led to the

invention of a global unique suit of

protocols called tcpip thus the Advent

of the internet let's talk about the

internet the internet is a sort of a

nickname of a global inter Network now

let's stop here and see what is a

network a network is a group of computer

systems two or more interconnected

together for the sake of communicating

and exchange Chang in data using links

these computer systems whether they are

laptops desktops smartphones TVs cars

Etc are called in terms of the network

nodes these nodes establish connections

between them using either cable Media or

wireless media so this is what we mean

by a network now the internet simply as

we said is a Global Network of networks

networks that are either private public

academic of business or government

actually there are millions of

interconnected networks out there and

that what makes the internet a Global

Network all what we have here is a

Global Network namely just

interconnected computers via cables or

wireless media using the global TCP IP s

of protocols to take advantage of this

huge Network and make use of it many

internet services has been created and

engineered such as mobile apps

electronic mail file sharing the

worldwide web online games internet

telephony Etc so all these services are

built on top of the internet thus they

are a part of it for now this is all

what you have to know about the internet

unless you want to dig into the

networking world and of course I'll

cover more things in the next videos

let's see then what is the worldwide web

or simply the web the worldwide web is

probably the most commonly used service

on the internet allowing people to

search get and share the data therefore

it's the most influential application in

this world to be more specific the web

is a sort of virtual system that

interconnect resources on the internet

such as documents images videos and many

other resources via hyperlinks and

referen it with Uris uniform resource

identifiers we use web browsers such as

Chrome Internet Explorer Firefox Safari

and other similar programs to have

access to web resources usually those

resources are presented in web pages

sometimes in structured interrelated

group of web pages called websites web

pages are created using HTML for

structuring the page CSS to sell it

usually to give it a nice look and we

use script and languages to add

interactivity to the web page and make

it more user friendly we still have a

lot to cover but in this video we just

try to differentiate the internet from

the web so to sum up we've seen that the

internet is a Global Network ofet

networks and that the network is a group

of interconnected computer systems we

have also seen that we make use of the

Internet by building on top of its

services such as the worldwide web file

sharing emailing Etc also the web is a

system of interconnected resources

resources that are presented in the web

using web pages or websites to access

these web pages or websites we use web

browsers I hope you found this video

useful and that you've learned something

from it and yeah don't forget to

subscribe tell the next video stay tuned
