37. 'A type of hard drive that uses much thinner cables - and can transfer data more quickly - than IDE drives.'






38. 'The essential component of the operating system that is responsible for managing the processor and all other components of the computer system. Because it stays in random access memory (RAM) the entire time the computer is powered on - the kernel is
