Memory organization
1.Recall:
-Information is stored in the memory as a collection of bits.
-Collection of bits are stored or retrieved simultaneously is called a word.
-Number of bits in a word is called word length.
-Word length can be 16 to 64 bits.
2.Another collection which is more basic than a word:
-Collection of 8 bits known as a "byte"
3.Byte are grouped into words, word length can also be expressed as a number of bytes instead of the number of bits:
-Word length of 16 bits, is equivalent to word length of 2 bytes.
4.Word may be 2 bytes (older architectures), 4 bytes (current architectures),or 8+ bytes (modern architectures).
