Memory: short term memory, RAM, random access memory. This is very fast, volatile, meaning that pull plug, no more data there. Stores this as electrical charges. more expensive, less space. random access, which is faster.
Storage: long term memory, e.g. hard disk. Usually slower. permanent rather than volatile. cheaper, get more space. sequential access, which is slower.

how computer stores Numbers, letters, programs, etc.
for homework, for yourself. count to 10 in binary. tell yourself what 0111 is in decimal.
ASCII (sometimes ANSI). American Standard Code for Information Interchange.
bits
binary digits
decimal = base 10
binary = base 2
we combine these bits
byte = 8 bits
the more bits, the greater range of values I can store.
many bytes:
1000 or 1024 bytes = 1 kilobyte
1 million bytes, or 1024 x 1024 bytes = 1 megabyte
trilobite = extinct marine arthropod
1 billion bytes or ... = gigabyte
1 thousand gigabytes, 1 trillion bytes = terabyte
1 byte = 8 bits
2 bytes = word
4 bytes = dword
4 bits = half a byte = nibble
