Transmitting & Receiving
Transmitting and receiving is a process that allows communication between information systems. For a successful communication between systems, there requires 3 basic components, sender, a medium and a receiver. The sender is responsible for encoding the information but requires a medium to be transferred across to the receiver. |
Application for software analysis include:
- Cloud based storage - Allows users to store data over the internet onto an online database, can be access by other devices in necessary. E.g. Goodle Drive, DropBox, iCloud.
- Email - Sends information over the internet via a server from one user to a another or group of people.
- Online gaming - Sends the users data onto a database where it is processed and relayed back.
Hardware required for this process include:
- Modems - A hardware device which controls a series of wave signals that can encode digital information.
- Router - Allows for the modems' signals to be accessible over a longer distance and have better signal quality.
- Ethernet Cables - Serves as a medium allowing for digital data and information be to transferred across systems without the need for wave signals.
Non-computer based tools
Types of ways to Transmit and Receive data without the use of a computer based system:
- Mail - Ability to send papers and photographs via the use of a postage system.
- Verbal Communication - Transferring semantics across people thought word of mouth.
- Morse Code - Flashing lights in a standardised sequence to form letters and sentences.
Social and Ethical Issues
- The rapid widespread of the use of digital data and its ease of transmission, particularly over the internet, has created a whole new set of social and ethical issues which include:
- Accuracy – Is the information and data being sent across be no be faulty or poorly sent to prevent confusion or misunderstanding.
- Authority
