What is the difference between enterprise networks and service provider networks?

Enterprise networks cover multiple locations and connect offices, while service provider networks provide internet access and connect customers and offices.

What is the difference between a LAN and a WAN?

A LAN is a small network or part of a bigger network, while a WAN is used to join networks together, such as connecting a bank's network with offices worldwide.

What devices are used in an enterprise network?

An enterprise network may have switches, routers, and access points to connect multiple locations and offices.

What is the purpose of a WAN?

The purpose of a WAN is to connect networks together, allowing communication between different locations or offices.

What is the purpose of a LAN?

A LAN is used to create a local network, either in a small office or as part of a larger network, to facilitate communication and resource sharing.

Key insights

💻

Understanding the foundations of networking is crucial for those studying for certifications like CCNA, Network + or JNCIA.
📶

Devices can be connected to a network either by plugging cables into a switch or by using a wireless access point, also known as Wi-Fi.
💻

Having both wired switches and wireless access points gives users more connection options, allowing for seamless transitions between wired and wireless connections depending on the situation.
🌐

Devices need to speak the same language in order to communicate and share information, which is achieved through protocols like Ethernet, TCP, HTTP, and SMTP.
🏢

While a SOHO network may only have a few devices, a corporation like a bank will have many devices on their network.
🏢

An enterprise network can cover multiple floors in a building or even multiple office buildings in different cities or countries, highlighting the importance of a reliable and efficient network infrastructure for businesses.
🌐

WANs connect networks that are far apart, while LANs are collections of network devices in a local area.
💻

The addition of a retail division and six branch offices raises the question of what type of network this is.

Timestamped Summary

👋

00:00
This video series is designed to help beginners understand the foundations of networking, starting with an explanation of what a network is and the different types, with future videos covering cabling and addresses.
💻

02:00
Devices like computers, printers, and TVs are connected through a network to share data and an internet connection, either by plugging cables into a switch or connecting wirelessly through a wireless access point.
💻

03:39
Wireless access points can be used instead of messy cabling, allowing for both wired and wireless devices to be part of the same network and providing more connection options.
💻

04:29
Networks connect devices that need to speak the same language, which is called a protocol, and different protocols are used depending on what's needed at the time.
📝

06:28
Nodes on a network include devices that control traffic like switches and routers, as well as end points or hosts like workstations, servers, and printers, with networks coming in different sizes such as a SOHO network for small offices or home offices, which typically have a few computers, a printer, phones, and tablets, with a router used to connect to the internet, and while switches and hubs may look similar, they are very different, with hubs being old technology and switches being modern and commonly used.
📡

08:15
Enterprise and service provider networks can cover multiple locations, while LANs and WANs connect smaller networks or join networks together.
📡

10:05
WANs connect networks that are far apart, while LANs are collections of network devices in a local area, and all networks vary in size.
👨‍💻

11:00
A LAN network can be formed by joining multiple networks, and as a company grows and adds branch offices, the network type changes, and in part two of the series, different types of cabling, Ethernet protocol, and network addressing will be discussed.
