| Define a byte | A byte is a set of 8 bits. Here is an example of 8 bits: 00011111 Every character that we know of (e.g. Z, ?, 3, l) is represented by a series of 8 bits. |
| How many bytes are in a kilobyte, megabyte, gibabyte, terabyte, petabyte, exabyte | these are approximations: kilobyte = 1000 bytes, megabyte = million bytes, gigabyte = billion bytes, terabyte = trillion bytes, petabyte = quadrillion bytes, exabyte = quintillion |
| On a brand new computer the typical storage size in bytes of a hard drive is | in terabytes |
| Define hardware and give examples | any physical component of a computer (mouse, monitor, system unit, mouse) |
| Define the two main categories of software and give examples of each category | system software (operating system, Windows ) and applications software: Microsoft Office Professional 2010, QuickBooks 2010, Turbo Tax, Crystal Reports |

| Define RAM. What would be the typical amount of RAM on a desktop computer? | RAM stands for Random Access Memory. It is volatile memory. When you start your computer, the operating system is copied into RAM. A program you lauch is copied into RAM. You should have at least 4GM of RAM. |
| Define ROM | Read only memory |
| How fast is a 3.5 GigaHertz computer. | The processor performs work at a rate of 3.5 billion machine cycles per second. |
| List examples of storage devices or locations | hard drive, external backup drive, online storage, CD, DVD, thumb drive, blu-ray disc |
| What is the most common port type to connect input and output devices to a computer | USB port (universal serial bus) 2.0 is the standard; keyboards, printer, mouse, external hard drive, thumb drives can be connected to a USB port |
| What is a warm boot | restarting the computer while it is powered on |
