Computer assembly

In its role as a high level assembler used for writing operating systems, C is often used to access memory locations and change individual bits. You might for example need to access individual bits in an int. It can sometimes be useful to conserve memory by using a byte to hold 8 flags though with an abundance of ram it's common to just use one byte per flag or even one per int. Knowing how to extract or alter individual bits is still worthwhile knowing; you may never have to use it but when you have to maintain code that...

Toovercome the difficultyof characterizing the structures of the extracellular loops (eLPs) ofGprotein-coupledreceptors (GPCRs) other than rhodopsin, we have explored a strategy to generate a three-dimensional structural model for a GPCR, the thromboxane A2 receptor. This three-dimen-sional structurewas completedby the assembly of theNMR structures of the computation-guided constrained peptides that mimicked the extracellular loops and connected to the conserved seven transmembrane domains.

Task A executes and starts to write the string “Hello world” to the LCD. Task A is pre-empted by Task B after outputting just the beginning of the string – “Hello w”. Task B writes “Abort, Retry, Fail?” to the LCD before entering the Blocked state. Task A continues from the point at which it was preempted and completes outputting the remaining characters – “orld”. The LCD will now be displaying the corrupted string “Hello wAbort, Retry, Fail?orld”.

Supercomputers are the most powerful computers. They are used for problems requiring complex calculations. Because of their size and expense, supercomputers are relatively rare. Supercomputers are used by universities, government agencies, and large businesses.

Hợp ngữ (assembler) là ngôn ngữ bậc thấp, giúp cho người lập trình không phải ghi nhớ mã máy (opcode) mà sử dụng các từ ngữ gợi nhớ (pseudo-code) gần với ngôn ngữ tự nhiên để miêu tả công việc cần thực hiện. Tuy vậy, assembler rất gần với ngôn ngữ máy, đòi hỏi người lập trình phải hiểu biết tương đối đầy đủ về cấu trúc phần cứng máy tính.
