Networking devices and connections are the focus of this Grade 9 Computer Science worksheet, helping students understand how devices communicate across local networks and connect to the wider internet. Students work with routers, wired and wireless connections, network infrastructure, and shared resources while using accurate networking vocabulary in context. :contentReference[oaicite:0]{index=0}

Build a clear model of how networks work

The lesson introduces a network as a group of connected devices and the paths that allow data to move between them. Students consider familiar devices such as laptops, phones, and printers and compare wired connections that use cables with wireless connections that use signals.

Routers are presented as an important part of network infrastructure. Students examine how a router receives data from one connection and sends it toward the correct destination, helping organize traffic so messages reach the intended device.

Connect local networks to the internet

• Explain how devices communicate through network connections
• Identify the role of a router in directing data
• Distinguish wired and wireless connection methods
• Describe how devices share resources on a local network
• Explain how a local network connects to the wider internet

Students also explore why local networks are useful in homes and classrooms. Connected devices can share files, storage, printers, and other services. When the local network links to the internet, the router and related networking hardware help data travel to websites and online services and return to the original device.

Practice networking concepts in multiple ways

A dialogue, matching activity, cloze passage, labeled diagram, and reading passage introduce the main vocabulary and relationships. Multiple-choice and true-or-false questions ask students to identify networking devices, connection types, shared resources, router functions, and local-network characteristics. Short-answer prompts require students to name network connections and explain why routers are useful.

The extended response brings the concepts together by asking students to explain how a local network connects devices and also provides internet access using the terms network, device, router, and connection.

Teacher support included

A separate teacher guide PDF includes learning objectives, teaching tips, discussion questions, and common mistakes. Use this computer networking worksheet when introducing Networks and Internet concepts, reviewing basic network infrastructure, or preparing students for later lessons on how data travels between connected systems.
