00:00.000 --> 00:09.000
Introduction to Computer Networks

00:09.000 --> 00:17.000
Local Area Network, LAN, Wide Area Network, WAN, LAN versus WAN

00:17.000 --> 00:21.000
Key differences, we are going to learn about computer networks

00:21.000 --> 00:28.000
Specifically, Local Area Networks, LAN, and Wide Area Networks, WAN

00:29.000 --> 00:33.000
These networks help us connect computers and share information

00:33.000 --> 00:36.000
LAN stands for Local Area Network

00:36.000 --> 00:41.000
It's like our classroom, small and close

00:41.000 --> 00:48.000
Devices here are connected in a limited area, like a home, school lab or office

00:48.000 --> 00:55.000
Characteristics, Fast, uses Cable's Wi-Fi and is managed by one person

00:55.000 --> 01:01.000
Example, when you print a project from a school computer, that's a LAN

01:01.000 --> 01:06.000
Offices use LANs to share printers and files between co-workers

01:06.000 --> 01:10.000
WAN stands for Wide Area Network

01:10.000 --> 01:13.000
Imagine connecting multiple classrooms across the globe

01:13.000 --> 01:18.000
WAN cover large areas, like cities or countries

01:18.000 --> 01:24.000
Characteristics, uses routers, satellites and even undersea cables

01:24.000 --> 01:28.000
slower than LANs because of the distance

01:28.000 --> 01:32.000
Example, the internet is the biggest WAN

01:32.000 --> 01:36.000
Companies with offices worldwide use WANs to share data

01:36.000 --> 01:47.000
LAN versus WAN, key differences, range, LAN, small, a building, WAN, huge countries

01:47.000 --> 01:53.000
Components, LAN uses switches slash Wi-Fi, WAN uses routers and satellites

01:53.000 --> 01:59.000
Speed, LAN equals faster, WAN slower

01:59.000 --> 02:08.000
Ownership and control, LAN equals privately owned with full control, WAN, multiple owners and limited control

02:08.000 --> 02:17.000
Use case, LAN for sharing printers, files, WAN for connecting branches or browsing the internet

02:17.000 --> 02:23.000
Let's brainstorm, picture a school scenario

02:23.000 --> 02:29.000
LAN, students in the lab working on a group project via shared folders

02:29.000 --> 02:36.000
WAN, the school's website, is accessible worldwide
