Networks
Bayani Gaba-gaba
Almost nothing a computer does today happens in isolation. A phone checking the weather, a laptop backing up to the cloud, a till in a shop confirming a card payment: every one of these is a conversation between machines, carried out over a network according to rules both sides agree to follow. This lesson opens up how that conversation actually works.
You will compare network types and usage models, wired versus wireless connections, and how speed is measured, before going layer by layer through the protocols that get a message from one device to another: physical topologies, the four-layer TCP/IP model, packet switching, and the specific protocols behind the web, file transfer and email.
Manufura
- Understand why computers are connected in a network
- Understand the different types of networks (local area network (LAN), wide area network (WAN), personal area network (PAN)) and usage models (client-server, peer-to-peer)
- Understand wired and wireless connectivity
- Understand that network data speeds are measured in bits per second (Mbps, Gbps)
- Understand the role of and need for network protocols (Ethernet, Wi-Fi, TCP/IP, HTTP, HTTPS, FTP, email (POP3, SMTP, IMAP))
- Understand that data can be transmitted in packets using layered protocol stacks and the 4-layer TCP/IP model (application, transport, network, data link)
- Understand characteristics of network topologies (bus, ring, star, mesh)
- Understand the different mobile communication standards (3G, 4G and subsequent generations)
