A very common task in the IT industry is needing to convert between storage size units - bytes, kilobytes, megabytes, gigabytes, terabytes, etc. To make things even more complicated, the POSIX ...
TWCN Tech News: Memory sizes explained – Bits, Bytes, Kilobytes Gigabytes, Terabytes, Petabytes, Exabytes
Ars Technica: Tell me again why a kilobyte is not 1,000 bytes?
Actually, according to the ISO, a kilobyte is 1000 bytes, because kilo is the standard SI prefix for (x)*10^3. They've defined a new set of prefixes for 2^10, 2^20, etc, under which 2^10 bytes ...
21 In .NET, a byte is basically a number from 0 to 255 (the numbers that can be represented by eight bits). So, a byte array is just an array of the numbers 0 - 255. At a lower level, an array is a contiguous block of memory, and a byte array is just a representation of that memory in 8-bit chunks.
Endianness and byte order When a value larger than byte is stored or serialized into multiple bytes, the choice of the order in which the component bytes are stored is called byte order, or endian, or endianness. Historically, there have been three byte orders in use: "big-endian", "little-endian", and "PDP-endian" or "middle-endian".
I have to store some constant values (UUIDs) in byte array form in java, and I'm wondering what the best way to initialize those static arrays would be. This is how I'm currently doing it, but I feel
