  • 1Learners will identify the four main types of network topologies and recall the defining structure of each
  • 2Ask learners: What devices do we find in a computer lab? Learners shout out (monitor, keyboard, printer, server) and you list them on the board. Then ask: How do you think these devices talk to each other? Allow 3–4 brief answers
  • UNDERSTANDING THE FOUR NETWORK TOPOLOGIES
  • 1Using the projector and computer/laptop, display a simple labelled diagram of the Bus Topology (a straight line of computers connected to one main cable). Explain: In Bus topology, all computers connect to one long cable, like students sitting on a bench in a line. Ask learners to repeat the definition chorally twice. Then display the Star Topology diagram (computers arranged in a circle around a central hub). Explain: One central device (the hub) connects to all computers, like a star with rays. Learners repeat chorally. Let learners work in pairs to keep all learners involved.
  • 2Display the Ring Topology diagram (computers forming a closed circle, each connected to exactly two neighbours). Explain: Data passes from computer to computer in a ring—like passing a message around a circle during assembly. Finally, show the Mesh Topology diagram (every computer connected to every other computer with many crisscrossing lines). Explain: In Mesh, computers have many backup paths—very safe but expensive. Learners pair-share: Which topology sounds strongest? Why? Invite one representative from each of three pairs to give their answer aloud
  • 3Struggling learners: focus on Bus and Star only, using simple labelled diagrams from the Textbook. Fast finishers: research one real-world use of each topology and write one sentence (e.g. Bus in older labs, Star in modern offices). Use pair or group support to manage the large class.
  • 1Computer/Laptop
  • 2Projector
  • 3Textbook (Computing Curriculum)
  • 4Internet connection (optional, for topology diagrams)
  • 1Learners stand and form four human groups (one for each topology). Each group acts out their topology: Bus group stands in a line, Star group forms a circle around one learner (the hub), Ring group forms a closed circle, Mesh group crisscrosses and links arms with multiple others. Call out a topology name; the correct group freezes and the class identifies it
  • 2Ask learners to rate their confidence on drawing each topology using fingers (1–5). Acknowledge those showing 5 fingers and ask one to explain what made it clear. For those showing 1–2, pair them with a confident learner to co-draw during the exercise
Exercise
  • 1On a blank page, draw and label diagrams for two topologies of your choice (Bus, Star, Ring, or Mesh). Write one sentence under each diagram describing how data moves. Check: Can you see the main shape (line, star, ring, or web)? in their exercise books.
