a. I/O Hardware. Devices communicate with the computer via signals sent over wires or through the air. Devices connect with the computer via ports, e.g. a serial or parallel port. A common set of wires connecting multiple devices is termed a bus.

b. The main difference between interrupt and polling is that in interrupt, the device notifies the CPU that it requires attention while, in polling, the CPU continuously checks the status of the devices to find whether they require attention. In brief, an interrupt is asynchronous whereas polling is synchronous.

c. flash memory

A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage.

Setler [38]

Answer:

The TAB key

Explanation:

Sam would use the TAB key, located on the left side of the keyboard, to move around his document to add stops and format its information properly.

Pressing the TAB key will introduce a tab code in his document, which is like moving ahead by a certain number of spaces (5,6, 10 spaces for example, depending on the configuration of the document), but without using spaces, using a tab which is a much better option to position, align things up.
