Why Networks?
  • They allow us to live in a connected world. 
  • Worldwide communication
  • Personal Devices can be networked.
  • We can share (lots), files information and data.

Definition of LAN
A Local Area Network (LAN) is a network that connects computers and devices in a limited geographical area, such as a home, school, or office building.

Slide 8 - Tekstslide

LANs are limited to specific geographical areas.
Agree: LANs are meant for localized connections.
Disagree: LANs can extend beyond geographical boundaries.

Local Area Networks (LAN)
Key Points
  • LANs are typically high-speed and provide secure and reliable communication within the defined area.
  • Covers a small geographical area located on a single site
  • All the hardware for a LAN is (usually) owned by the organisation
  • LANs are wired with UTP cable, fibre optic or wireless using Wi-Fi

Slide 10 - Tekstslide

Definition of WAN
A Wide Area Network (WAN) is a network that covers a broad area, often connecting multiple LANs and other networks across long distances.

The use of WAN technology enables businesses to link geographically dispersed offices and provide centralized access to resources.
Agree: WAN technology facilitates centralized access
Disagree: WAN technology does not support centralized access
Support: WAN technology improves operational efficiency
Oppose: WAN technology does not enhance operational efficiency

Slide 13 - Poll

Wide Area Network WAN
Key Point's  
  • Covers a large geographical area, connecting LANs together
  • Infrastructure between LANs is leased from telecommunication companies who own and mange it. 
  • WANs are connected with telephone lines, fibre optics or satellite links.

Slide 14 - Tekstslide

Deze slide heeft geen instructies

Differences Between LAN and WAN
LANs are confined to a limited area, while WANs cover a larger geographical area and often rely on public infrastructure.

Slide 15 - Tekstslide

Deze slide heeft geen instructies

Applications of LAN
LANs are commonly used for sharing resources, such as files and printers, within a small area, and for facilitating local communication.

Slide 16 - Tekstslide

Deze slide heeft geen instructies

Applications of WAN
WANs enable organizations to connect geographically dispersed offices, access cloud services, and facilitate internet connectivity across regions.

Slide 17 - Tekstslide

Slide 22 - Open vraag

Deze slide heeft geen instructies

Write down 3 things you learned in this lesson.

Slide 23 - Open vraag

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

Slide 24 - Open vraag

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
Ask 1 question about something you haven't quite understood yet.

Slide 25 - Open vraag

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
