WRITTEN ASSIGNMENT

QUESTION 1ANSWER : LINUX

QUESTION 2ANSWER :

USB 1 Carries data at the rate of 12 megabits per seconds, which is sufficient for medium to low-speed peripherals. It also can provide an interface for Integrated Services Digital Network (ISDN) and digital PBXs. USB 1 operating an old versions of computer operating systems and peripherals.

USB 2Carries data at the rate of 480 megabits per second, about 40 times the rate of USB 1. It can have 4 wire in 1 cable and the maximum length of the cable is 5 meter. Its power usage is up to 500mA. This is sufficient for most modern high-speed devices. USB 2 is backwards compatible with USB 1 devices, meaning you can plug in a peripheral device made for USB 1 to a USB 2 port. The power carrying capacity of USB 2 allows you to plug in non-signal products that just need power.

USB 3Carries data at the rate of 4.8 gigabits per seconds, about 10 times the rate of USB 2 and 400 times the rate of USB 1 . It can have 9 wire in 1 cable and the maximum length of the cable is 3 meter. Its power usage is up to 900Ma and can allows better power efficiency with less power for idle states. It also can power more devices from one hub.
