Transmitting And Receiving

Transmitting and receiving – the process that transfers information and data within and between information systems
• hardware for transmitting and receiving
– communications within a computer between peripheral devices and the CPU via buses
– 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
– acknowledgment of data source
– global network issues, time zones, date fields, exchange rates
– changing nature of work for participants, such as work from home and telecommuting
– current developments and future trends in digital communications, radio and television
– the impact of the Internet on traditional business
• demonstrate sending and receiving mail, with attachments, over an e-mail system
• select a relevant technology for a given situation to allow computers to transmit and receive data or information
• compare and contrast computer and non-computer based communication systems
• describe and employ net-etiquette when using the Internet
• predict and discuss possible future trends in communications and the impact they are likely to have on the transmitting and receiving of data/information
