Networks and the web
How data moves: serial links and protocols, topologies and Wi-Fi, packets, TCP/IP, addressing, DHCP and NAT, security, REST and the web, ending with a robot that rebuilds a route from damaged packets.
Start in the simulator- A12.1 Communication methods Serial and parallel, synchronous and asynchronous, baud rate, bit rate, bandwidth, latency and protocols.
- A12.2 Topologies and wireless networks Physical and logical bus and star; Wi-Fi, SSIDs, WPA2 and CSMA/CA with RTS/CTS.
- A12.3 How the Internet works Packet switching, routers and gateways, URLs, fully qualified domain names and DNS.
- A12.4 The TCP/IP stack and protocols The four layers, encapsulation, ports and sockets, and HTTP, HTTPS, FTP, SMTP, POP3 and SSH.
- A12.5 IP addresses and subnets Network and host identifiers, subnet masks with AND, IPv4 and IPv6, public and private addresses.
- A12.6 DHCP, NAT and port forwarding How a device gets its address, and how a router shares one public address with a whole network.
- A12.7 Internet security Firewalls, packet filtering, proxies and stateful inspection; encryption, certificates and signatures; worms, trojans…
- A12.8 Client server, REST and thin clients Peer to peer and client server, websockets, CRUD and REST with JSON, and thin versus thick clients.
- A12.9 Web technologies and search HTML, CSS and JavaScript, client and server side processing, indexing and PageRank.
- A12.10 Project: a reliable link Receive a route as packets out of order, reject the damaged one, and drive it.
