Job Stream
In a non-interactive computer system, particularly IBM mainframes, a job stream, jobstream, or simply job is the sequence of job control language statements (JCL) and data (called ''instream data'') that comprise a single "unit of work for an operating system". The term ''job'' traditionally means a one-off piece of work, and is contrasted with a ''batch'' (executing the same steps over many inputs), but non-interactive computation has come to be called "batch processing", and thus a unit of batch processing is often called a ''job'', or by the oxymoronic term batch job; see ''job'' for details. Performing a job consists of executing one or more programs. Each program execution, called a ''job step'', ''jobstep'', or ''step'', is usually related in some way to the others in the job. Steps in a job are executed sequentially, possibly depending on the results of previous steps, particularly in batch processing. The term "job stream" is particularly associated with mainframes; in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-interactive
Across the many fields concerned with interactivity, including information science, computer science, human-computer interaction, communication, and industrial design, there is little agreement over the meaning of the term "interactivity", but most definitions are related to interaction between users and computers and other machines through a user interface. Interactivity can however also refer to interaction between people. It nevertheless usually refers to interaction between people and computers – and sometimes to interaction between computers – through software, hardware, and networks. Multiple views on interactivity exist. In the "contingency view" of interactivity, there are three levels: #Not interactive, when a message is not related to previous messages. #Reactive, when a message is related only to one immediately previous message. #Interactive, when a message is related to a number of previous messages and to the relationship between them.
