text: what is the difference between 1.1 ghz and 60 g as far as speed?   hard disk - this is large-capacity permanent storage used to hold information such as programs and documents.  central processing unit (cpu) - the microprocessor "brain" of the computer system is called the central processing unit. everything that a computer does is overseen by the cpu.  1.1ghz still will not tell you the full extent of the power behind the computer.  things like celeron, pentium, pentium 4, pentium m, all help understand how powerful a computer is.  60 gb is easy to  put in simple terms.   1 gb = 1024 mb 1 cd = 700 mb 1 dvd = 8.5 gb  so that 60 gb can hold  7 dvds or  87 cds or  42,666 floppy disks
