The FLAGS register is the status register that contains the current state of an x86 CPU.The size and meanings of the flag bits are architecture dependent. It usually reflects the result of arithmetic operations as well as information about restrictions placed on the CPU operation at the current time.
A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor.Examples of such registers include FLAGS register in the x86 architecture, flags in the program status word (PSW) register in the IBM System/360 architecture through z/Architecture, and the application program status register (APSR) in the ARM Cortex-A architecture.
The computation produced as output from the operands is specified by a set of six ordered, single-bit inputs to the ALU. The ALU also emits two single-bit status flags which indicate whether a computation result is zero (zr flag) or negative (ng flag). The CPU also contains two 16-bit registers, labeled D and A. The D (Data) register is a ...

The memory responds by sending the contents of that memory location on the data bus. (This is the stored-program computer model, in which a single memory space contains both executable instructions and ordinary data. [9]) Following the fetch, the CPU proceeds to execution, taking some action based on the memory contents that it obtained. At ...

Eidetic memory (/ aɪ ˈ d ɛ t ɪ k / eye-DET-ik), also known as photographic memory and total recall, is the ability to recall an image from memory with high precision—at least for a brief period of time—after seeing it only once [1] and without using a mnemonic device.
The Flag of Australia employs five heptagrams and one pentagram to depict the Southern Cross constellation and the Commonwealth Star. Some old versions of the coat of arms of Georgia (country) including the Georgian Soviet Socialist Republic used the {7/2} heptagram as an element.
