The Job Entry Subsystem (JES) is a component of IBM's MVS (MVS/370 through z/OS) mainframe operating systems that is responsible for managing batch workloads. In modern times, there are two distinct implementations of the Job Entry System called JES2 and JES3. They are designed to provide efficient execution of batch jobs.

IBM implemented five models of the 1131 Central Processing Unit, the primary processing component of the IBM 1130. The Model 1 through Model 5 describe the core memory cycle time, as well as the model's ability to have disk storage. A letter A through D appended to the model number indicates the amount of core memory installed.
Job Control Language (JCL) is a scripting language used on IBM mainframe operating systems to instruct the system on how to run a batch job or start a subsystem. [1] The purpose of JCL is to say which programs to run, using which files or devices [2] for input or output, and at times to also indicate under what conditions to skip a step.
The first operating systems for IBM computers were written in the mid-1950s by IBM customers with very expensive machines at US$2,000,000 (equivalent to about $23,000,000 in 2023), which had sat idle while operators set up jobs manually, and so they wanted a mechanism for maintaining a queue of jobs.
A new-collar worker is an individual who develops technical and soft skills needed to work in the contemporary technology industry through nontraditional education paths. [1] [2] The term was introduced by IBM CEO Ginni Rometty in late 2016 and refers to "middle-skill" occupations in technology, such as cybersecurity analysts, application developers and cloud computing specialists.
