So it was still limited to the gigabytes of RAM which in that day and age was an enormous amount of memory. Moving into the 64-bit realm it actually allows us terabytes of RAM so huge amounts of vast storage that we can use for working with programs now some of the history about the 8-bit 16-bit 32-bit microprocessor is actually the first 8-bit microprocessor that I really know of is the Intel 8008 it was produced in 1972 it was the first general-purpose 8-bit microprocessor microcontroller and then what’s really,interesting is it didn’t take very long,for the world to get to 16-bit 32-bit and 64-bit in fact the Cray 1,supercomputer was using 64-bit register,length so come feel a huge amounts of data and that was in the 70s and 80s but it actually only,had a 32-bit memory addressing space. Realistically it was around three point-two five gigabytes of RAM no. That meant it could address 2 to the 32nd unique memory spaces this limit us to an effective about 4 gigabytes of RAM. If you move to 16-bit that is actually 65,000,approximate and if you move up to 32 you’re in the 4.3 million range.So as you want to work on larger and larger numbers you actually need greater ,register widths so you can actually deal with them low register lengths when you’re dealing with the 8-bit 16-bit,32-bit 64-bit in the memory addressing space it’s actually something we ran into recently with computer memory all of our personal computers generally were based around the 32-bit microprocessor. Today we’re,talking about some tech trivia and I’m,not going to go super deep into the technology behind this but I wanted to cover what the heck doesn’t mean when something says it is 8-bit 16-bit 32-bit,or 64-bit or even hundred and twenty 8-bit in the future when we’re talking specifically about microcontrollers and micro processors well that can refer to the data bus with the addressing width so kind of how many different unique memory addresses can it understand or the register width and the register width is really how much data.Can you manipulate at once with an 8-bit microprocessor that is treated as 2 to the 8th so that is 255 unique numbers so 0 through 255 because it’s 2 to the 8th minus 1.
