64-bit computing 64-bit computing In computer architecture, 64-bit computing is the use of processors that have datapath widths, integer size, and memory address widths of 64 bits (eight octets). Also, 64-bit computer architectures for central processing units (CPUs) and arithmetic logic units (ALUs) are those that are based on processor registers, address buses, or data buses of that size. From the software perspective, 64-bit computing means the use of code with 64-bit virtual memory addresses. However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and ARMv8, for example, support only 48 bits of virtual address, with the remaining
Byte serving data. It is often used when a server does not know exactly how much data there will be in the total response, allowing the server to start sending data to the client straight away without having to buffer the response and determine the exact length before it begins sending it to the client. This improves latency and reduces memory requirements while preserving the ability to reuse the connection after the response is completed. Byte serving and chunking are compatible and can be used with or without the other. Byte serving Byte serving (other names: RFC 7233 says the client makes
