Memory: a big array of electrical signals, different charge levels are interpreted into 0s and 1s (a.k.a bits) that computers can comprehend

1 byte (smallest indexable memory, addressable) = 8 bits ( or 2^3 bits )

1KB = 2^10 bytes (1024 bytes)

1MB = 2^10 KB (1024 KB)

1GM = 2^10 MB (1024 MB)

[Representation of Data in Memory]

Memory is basically a very long array of byte values

• Left column is the memory address and right column is the data value in binary
• Each row has a storage size of one byte (8 bits)
