Threads allows advertisers to create a profile and add their entire Instagram following practically instantaneously. With the native format of the platform being text-based, significantly fewer resources are required to produce content in comparison to video or even static assets.A thread is also known as a lightweight process. The idea is to achieve parallelism by dividing a  [ sign language alphabet  ](https://signlanguagealphabet.org/)   process into multiple threads. For example, in a browser, multiple tabs can be different threads. MS Word uses multiple threads: one thread to format the text, another thread to process inputs, etc.A thread is, fundamentally, a clear, well-defined theme, subject, topic or focus. A thread may exist in human communication, such as a topical group chat or email exchange. A thread also exists as the processing focus of a software program, such as an operating system (OS) or application.
