  BITS AND BYTESThe computer only understand two things, those two things are. ON- is represented by the number 1. OFF-is represented by 0. This is based on the BINARY NUMBER SYSTEM, this digits are known as bits.

  Bit:  A bitis a  b inary dig it . It's the most basic unit of information. It has a value of either 0 (zero) or 1 (one). Byte:  A group of eight bits. A byte can hold 256 values, from 0 to 255. Generally, a byte holds one character (A through Z, 0 through 9, etc).

  BITS AND BYTESBYTE- is a contraction of the words… B inar Y digi T s E ight This means that one byte consists of eight bits. A byte is necessary in order for the computer to store a character of information. So in terms of storage space a byte can be considered to be the size of a character.

  Here's how thedecimal base number 217 is represented in binary form. Note that because it's less than 255, it "fits" within a single byte (which contains only 8 bits). Isn't that neat?   The rightmost bit represents 2 to the zero power, or 1. The bit to its left represents 2 to the first power, or 2. The third bit from the right represents 2 squared (2 2 ), or 4. The fourth bit from the right represents 2 cubed (2 3 ), etcetera.   Add all eight values together; the sum is the value of the byte.

  FILES Files areclumps of computer data stored somewhere in your computer. Each file has… NAME LOCATION LENGTH DATE
• 20.
  WHAT DO FILESDO? Files hold and store information that can be read by the computer.
• 21.
  KINDS OF FILESName Inside Does/html .com instructions It runs or execute .exe instructions It runs or execute .txt Readable info. To read .gif Graphical info. To see .htm/html Textual info. To see using a browser.

  WHAT DO YOUDO WITH FILES? RUN THEM- if they hold program. LOOK INSIDE THEN- if they hold graphics information or text.
