Content Covered:
· understand why computers are connected in a network
· understand different types of networks (LAN, WAN)
· understand how the internet is structured (IP addressing, routers)
· understand how the characteristics of wired and wireless connectivity impact on performance (speed, range, throughput, bandwidth)
· understand that network speeds are measured in bits per second (kilobit, megabit, gigabit) and be able to construct expressions involving file size, transmission rate and time
· understand the role of and need for protocols (Ethernet, Wi-Fi, TCP/IP, HTTP, HTTPS, FTP and email (POP3, SMTP, IMAP))
· understand how the 4-layer (application, transport, network, data link) TCP/IP model handles data transmission over a network
