A 256-bit number means a binary number 256 digits long. Binary means the value is represented with two symbols, either 0 or 1. Binary numbers can be converted to any other format, for example decimal ...

Miners, hashes, keys, cold storage, blocks—it can all get confusing. Learn more about it all so that you can understand how Bitcoin works beyond a wallet.

It’s a field that need not be expensive or difficult to work in, as [Henk Mulder] shows us with his 4-bit analogue random number generator.

This is traditionally stored as a 32-bit number (which is going to cause some trouble in 2038), and it's currently speculated that 64-bit iPhones are doing something peculiar when handling system ...

Marketing guys love bigger numbers. Bigger is better, right? After all, Subway called it a “footlong” not an 11-incher. So when it comes to analog to digital (A/D) conversion, more bits are ...

R1 is now bits 17 through 32 of this number, and more operations can be chained together to keep extending the range of the number. With a bit more work, you can support arbitrarily large integer ...

On the Bitcoin blockchain, the nonce is a number used when a miner generates a hash from the block header to compare to the network difficulty target.

What do LSB (least-significant-bit) specifications mean when you are looking at ADCs? A fellow engineer told me that a 12-bit converter from Manufacturer X had just seven usable bits. So, essentially ...

A 16-bit number space gives you 65,536 possible numbers (AS numbers 0 – 65535). Out of these, the IANA reserves 1,026 of them: 64512 – 65534 for private, reusable ASNs (similar to private ...

This a number that can be described in 18-bits. However, modern public key cryptosystems depend on significantly bigger numbers that can be described in 2048 bits or more. That's why these ...
