measured
3. Processor - is an integrated electronic circuit that performs
the calculations that run a computer. A processor performs
arithmetical, logical, input/output (I/O) and other basic
instructions that are passed from an operating system (OS).
4. Video card - is used to process images so they can be
displayed on your monitor. A good video card can make a big
difference in the quality of your graphics, so this is particularly
important if you play games or work with photography and
video.

5. Measurements can be categorized into two:

6. Common Units of Measurement

7. Digital Storage Units of Measurement

10. Digital Representation
Within a computer, information is represented and stored in
a digital binary format. The term bit is an abbreviation of
binary digit and represents the smallest piece of data. It’s
also the most common unit of digital data storage. Humans
interpret words and pictures; computers interpret only
patterns of bits. A bit can have only two possible values, a
one digit (1) or a zero digit (0).

12. Digital Representation
Computers use binary codes to represent and interpret
letters, numbers and special characters with bits. A
commonly used code is the American Standard Code for
Information Interchange (ASCII). With ASCII, each character
is represented by a string of bits. For example:
Capital letter: A = 01000001
Number: 9 = 00001001
Special character: # = 00100011

15. DECIMAL TO BINARY CONVERSION
To convert a decimal number to binary, all you have to do is
divide the number by 2. Get the quotient and the
remainder. Bring down the quotient, divide it by 2, and get
the quotient and remainder again. Do it repeatedly until the
quotient results to 0. Copy the remainder from bottom to
top, and that is the binary equivalent.
