Memory Addresses

1.Storage cells are typically viewed as being byte-sized
 

Usually the smallest addressable unit of memory
 

•Few machines can directly access bits individually
 

Such addresses are sometimes called byte-addresses
 

2.Memory is often accessed as words

 

Usually a word is the largest unit of memory access by a single machine instruction
 

CLEAR’s word size is 8 bytes (= sizeof(long))

 

 A word-address is simply the byte-address of the word’s first byte
