1 K = 1024 bytes; 1 TB ≈ 10^12 bytes
A byte is a unit of computer storage that can hold a single character (e.g. the letter "a" or the nymber "2").
The symbol K stands for kilobytes.
A kilobyte (K or KB) is 2^10 bytes = 1024 bytes ≈ 1000 bytes.
Thus, the Apollo computer had 2048 bytes (about 2000 bytes) of memory.
A terabyte (TB) is 2^40 bytes = 1.099 511 627 776 × 10^12 bytes ≈ 10^12 bytes
