– the role of modems, including modulation and demodulation
– local area networks and wide area networks
• software for transmitting and receiving
– communications packages
– transmitting and receiving text, numeric, image, audio and video
– electronic mail and its operation
• identify examples of potential human bias in data processing
• differentiate between the requirements for a local area network and a wide area network
• transfer numeric, text, image, audio and video data and discuss the time to transfer and required bandwidth
• describe concepts of downloading, uploading and streaming
• non-computer tools for transmitting and receiving, such as mail, phone, fax and radio and television (transmit only)
• social and ethical issues associated with transmitting and receiving
– accuracy of data received from the Internet
– security of data being transferred
– net-etiquette
