The dangling else is a problem in programming of parser generators in which an optional else clause in an if–then(–else) statement can make nested conditional statements ambiguous. Formally, the reference context-free grammar of the language is ambiguous , meaning there is more than one correct parse tree .
In computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions ...
With forwarding enabled, the Instruction Decode/Execution (ID/EX) stage of the pipeline now has two inputs: the value read from the register specified (in this example, the value 6 from Register 1), and the new value of Register 1 (in this example, this value is 3) which is sent from the next stage Instruction Execute/Memory Access (EX/MEM ...
The values are preserved until the instruction causing the conflict has passed through the execution stage. [3] Such an event is often called a bubble, by analogy with an air bubble in a fluid pipe. In some architectures, the execution stage of the pipeline must always be performing an action at every cycle.
Its advantages are simplicity and low cost while its disadvantages are lack of elasticity, fault tolerance and scalability. [1] Connecting elements into a pipeline is analogous to function composition. Narrowly speaking, a pipeline is linear and one-directional, though sometimes the term is applied to more general flows.
In computer science, software pipelining is a technique used to optimize loops, in a manner that parallels hardware pipelining.Software pipelining is a type of out-of-order execution, except that the reordering is done by a compiler (or in the case of hand written assembly code, by the programmer) instead of the processor.

Azure Linux, previously known as CBL-Mariner (in which CBL stands for Common Base Linux), [3] is a free and open-source Linux distribution that Microsoft has developed. It is the base container OS for Microsoft Azure services [ 4 ] [ 5 ] and the graphical component of WSL 2 .
