The letter s after http refers to also often see the padlock sign http over secure. It is slower to use https than http; https is usually only adopted where sensitive or private data is being transferred across the internet. 5 Web browsers A WEB BROWSER is software which allows a user to display a web page on their computer screen.

14 59 The output, X, will have a value of 1 if any of the following combination of conditions occur: • either turbine speed <= 1000 rpm and bearing temperature > 80°C • or turbine speed > 1000 rpm and wind velocity > 120 kph • or bearing temperature <= 80°C and wind velocity > 120 kph. Design the logic circuit and complete the truth table to produce a value of X =1 when any of the three conditions above occur. This is a different type of problem to those covered in Examples 1 and 2. This time a real situation is given and it is necessary to convert the information into a logic statement and then produce the logic circuit and truth table.

4 Universal Serial Bus (USB) The UNIVERSAL SERIAL BUS (USB) is an asynchronous serial data transmission method. It has quickly become the standard method for transferring data between a computer and a number of devices. Essentially, the USB cable consists of: • a four-wire shielded cable • two of the wires are used for power and the earth • two of the wires are used in the data transmission. When a device is plugged into a computer using one of the USB ports: • the computer automatically detects that a device is present (this is due to a small change in the voltage level on the data signal wires in the cable) • the device is automatically recognised, and the appropriate DEVICE DRIVER is loaded up so that computer and device can communicate effectively • if a new device is detected, the computer will look for the device driver which matches the device; if this is not available, the user is prompted to download the appropriate software.
