🔍 Key Topics You’ll Master:

This Networks pack covers all essential areas required by the OCR GCSE Computer Science J277 specification. You’ll gain a thorough understanding of:

💻 Types of Networks:

• LAN (Local Area Network) and WAN (Wide Area Network) – Understand the key differences, advantages, and typical use cases.

• Explore personal area networks (PANs) for small-scale connections.

🌐 Network Topologies:

• Study Star and Mesh network topologies.

• Learn how devices connect in each layout, how data travels, and the advantages and disadvantages of each structure.

🔗 Wired and Wireless Networks:

• Compare wired connections (such as Ethernet) with wireless connections (like Wi-Fi and Bluetooth).

• Understand the factors that affect the performance of a network, including bandwidth, latency, interference, and error rates.

⚙️ TCP/IP Model and Networking Layers:

• Develop a solid understanding of the TCP/IP four-layer model used to organise data transmission over networks.

• Break down the four key layers:

  • Application Layer: Manages communication between applications, e.g. web browsers and email clients.

  • Transport Layer: Ensures reliable data delivery, handles packet switching and retransmission if errors occur.

  • Internet Layer: Controls addressing and routing of data using protocols like IP.

  • Link Layer: Manages physical connections, including hardware and device drivers.

• Learn how data flows through each layer and why this layered structure is essential for effective communication.

📡 Key Network Protocols:

• Study important protocols and their specific roles:

  • HTTP and HTTPS – For web communication.

  • FTP – For transferring files.

  • SMTP and IMAP – For sending and receiving emails.

  • TCP/IP – For organizing, packaging, and sending data reliably.

• Understand how protocol stacks work and why protocols must follow agreed standards.

🌐 The Internet and the Cloud:

• Learn what the Internet is and how it connects millions of devices globally.

• Understand the role of servers, IP addresses, and domain names.

• Explore the Cloud – its advantages, disadvantages, and how it enables remote storage and computing.

• Gain an understanding of virtual networks and how they can securely and efficiently segment larger networks.

🚀 Factors Affecting Network Performance:

• Examine how bandwidth, number of connected devices, signal quality, and the type of transmission media impact speed and reliability.

• Understand how different hardware choices (such as routers and switches) influence network performance.
