sequential access is a method of data access where information in a storage device is accessed in a sequence or order. it's like listening to songs on a cassette tape; you must go through each song to reach the one you want. this is different from random access where any data can be ...
What is a no-operation (NOP) instruction? NOP is an assembly language instruction, command, or other kind of signal that tells a computer to do nothing. You'll encounter it in various contexts where it's necessary to have an operation that alters the state of the machine in no way. Thi...
A lexical analyzer -- or scanner -- takes code from the preprocessor and breaks it into smaller pieces. It groups the inputcodeinto sequences of characters called lexemes, each of which corresponds to atoken. Tokens are units of grammar in theprogramming languagethat the compiler understands. L...
The order of operations is the rule that tells us the sequence in which we should solve an expression with multiple operations. A way to remember that order is PEMDAS. Each letter in PEMDAS stands for a mathematical operation. Order of Operations Steps: ...
The objects involved in the operation are listed from left to right according to when they take part in the message sequence. Below is a sequence diagram for making a hotel reservation. The object initiating the sequence of messages is a Reservation window. Note That: Class and object diagrams...
A sequence diagram is one of the multiple types of system interaction diagrams used within Unified Modeling Language (UML) to visually represent interactions between the objects that live within a system. Specifically, sequence diagrams provide a view of the order in which those interactions occur th...
For example, you might zero in on a rep who’s crushing their quota and determine that it’s because of a specific outreach cadence — the order and timing of steps that the sales rep goes through to move prospects throughthe sales pipeline. Sales ops would then bake that sequence into ...

It’s a mystery. Here’s how Thompson explains the current state of understanding: “There’s a huge ‘we just don’t know’ in the middle of my explanation. What we know is that it takes your entire question as a sequence of tokens, and at the first layer processes all of those ...
But sometimes, the outcomes of a Python snippet may not seem obvious at first sight.Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be...
