OPERATION OF ICT-BASED GADGETS
Below is the description of ways ICT-based gadgets work:
- Mobile Phone: This has both a transmitter which can transmit or carry signals and a receiver which can receive or collect signals. When a phone is made, the human voice is converted into an electrical signal and transmitted as radio waves by the transmitter. These signals are received by the nearest cellular base station and then redirected to the destination phone. The receiver in the mobile phone of the other person then converts the radio waves back to electrical signal and then to voice which is heard by the person who receives the call.
- Computer System: When a computer is switched on, the Basic Input and Output System (BIOS) checks to see if the Random-Access Memory (RAM) installed is working. It then loads itself into memory and starts up the loading of the Operating System into the memory. This process continues until the computer gets to the desktop environment where it is ready for use.
