A group of crows is called a âmurder.â There are several different explanations for the origin of this term, mostly based on old folk tales and superstitions. For instance, there is a folktale that crows will gather and decide the capital fate of another crow.
Execution (computing) For other uses, see Execution (disambiguation). Execution in computer and software engineering is the process by which a computer or a virtual machine performs the instructions of a computer program. The instructions in the program trigger sequences of simple actions on the executing machine.
The main purpose of a CPU is to execute instructions. We've already seen some simple examples of instructions, i.e., add and addi. The CPU executes the binary representation of the instructions, i.e., machine code.Since programs can be very large, and since CPUs have limited memory, programs are stored in memory (RAM).o fetch an instruction involves the following steps: 1  CPU must place an address to the MAR. 2  CPU must activate the tri-state buffer so MAR contents are placed on the address bus. 3  CPU sends R/\W = 1 and CE = 1 to memory, to indicate it wants to do a read. 4  Memory eventually puts instruction on the data bus.
