CORE DEFINITION

Deadlock, also translated as dead knot, is a computer science term. When two or more computing units are each waiting for the other to stop executing in order to acquire system resources, but no one exits early, it is called deadlock. In multitasking operating systems, to coordinate different threads and whether they can acquire system resources, the operating system must solve this problem for the system to function properly. Another similar situation is called 'livelock'.

Anchor fast decisions

Two or more processes/threads continuously change state to 'yield' to each other to avoid conflict, resulting in none being able to proceed; unlike deadlock, resources are busy rather than frozen, and the system spins idly.

Zero-Knowledge Proof

In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true, without conveying any information apart from the fact that the statement is indeed true. Thus, it can be understood as a 'zero-leakage proof'.

Batching

A batch file is a script file in DOS, OS/2, and Microsoft Windows, used as a scripting language to run programs. It is a text file containing a series of commands to be read and executed by an interpreter with a command-line interface. It is applied in DOS and Windows systems, interpreted and run by the built-in interpreter (usually COMMAND.COM or CMD.EXE). It is equivalent to a shell script in Unix-like systems. In DOS and Windows 9x operating system families, the file extension for batch files is .bat. In OS/2 and Windows NT families, the .cmd extension is added. In other operating systems, batch files may have different extensions, for example, 4OS, 4OS2, and 4NT use the .btm extension. When a batch file is executed, the shell program reads the file content and then executes its commands, typically line by line.

Head-of-Line Blocking

Head-of-line blocking (HOL blocking) is a performance-limiting phenomenon in computer networking. It occurs when the first packet in a queue (the head) is blocked, causing the entire queue of packets to be blocked. This can happen in switches with buffered inputs, due to out-of-order transmission, or in HTTP pipelining with multiple requests.
