firewall- firewall software that protects a computer by preventing unauthorized access and protecting it from being infected by undesirable data from the Internet
hard disk- drive a device that uses a disk to permanently store all computer data within files and folders; these drives spin very fast (up to 7,200 RPM) with data accessible from any place on the drive. (these drives are very slow at reading data)
Moore's law- the theory that such computing characteristics as processing speed, memory capacity, and sensors double every two years; a rate described as exponential. Also that the space between transistors and the silicon can only get so small.
Moniter-the monitor displays the computer's user interface and open programs, allowing the user to interact with the computer, typically using the keyboard and mouse
The last two dont make much sense
