Networks? What are they all about?

We will be looking at Networks. Here is the CXC CAPE syllabus outline:













Specific Objective 4 Distinguish among networked, client-server, and distributed;

=>Networking: Network management (user accounts, access logs) Networking Protocols (TCP/IP)

=>Network Architecture: Ethernet, FDDI.

=>Network topology: Star, Ring, Bus, Hybrid

=>Network devices: Modems, switches, routers, bridges, network interface cards (NIC), hubs.

=>Transmission media: wired (twisted pair, fibre-optics, coaxial); wireless (satellite, microwave) IEEE1394 (Firewire) and cable connectors using diagrams.

=>Protocol: Transmission Control Protocol/Internet Protocol (TCP/IP), File Transfer Protocol (FTP), Hypertext Transfer Protocol(HTTP); Hypertext Transfer Protocol Secure Sockets Layer(HTTPS); IEEE802.11a/b; IEEE802.16g; characteristics of Voice Over Internet Protocol; Open System Interconnection (OSI) model.

=>Access Methods for mobile networks: CDMA, TDMA, GSM, GPRS

=>Network consideration: cost, security, management, expandability, interconnectivity, wired vs wireless.

=>Network Configuration: Types: Multi-user; client server, centralized vs. distributed system, peer to peer.

=>Network Security: Firewalls


Specific Objective 5: Design Simple Networks.

=>Use diagrams to design networks.

My question to you is, what do you know about Networks? Give a paragraph summary of what you know.
