IBM-IS-DCI-UR-Newsletter.Pdf
Monthly Newsletter Mar 2016 Monthly Journal on Technology Know-How of IBM’s Technology space Tech Updates on Mainframe Platform “Mainframe“ the IBM Dictionary Of Computing defines "mainframe" as "a large computer, in particular one to which other computers can be connected so that they can share facilities the mainframe provides (for example, a System/370 computing system to which personal computers are attached so that they can upload and download programs and data). The term “Mainframe “ usually refers to hardware only, namely, main storage, execution circuitry and peripheral units“ level, as opposed to trying to do it all from the System z platform. Did you know that mainframes and all other computers have two types of physical storage: Internal and external. Physical storage located on the mainframe processor itself. This is called processor storage, real storage or central storage; think of it as memory for the mainframe. Physical storage external to the mainframe, including storage on direct access devices, such as disk drives and tape drives. This storage is called paging storage or auxiliary storage. The primary difference between the two kinds of storage relates to the way in which it is accessed, as follows: Central storage is accessed synchronously with the processor. That is, the processor must wait while data is retrieved from central storage. Auxiliary storage is accessed asynchronously. The processor accesses auxiliary storage through an input/output (I/O) request, which is scheduled to run amid other work requests in the system. During an I/O request, the processor is free to execute other, unrelated work. -
A Practical Introduction to Computer Architecture
A Practical Introduction to Computer Architecture Daniel Page [email protected] h i git # ba293a0e @ 2019-11-14 © Daniel Page [email protected] h i git # ba293a0e @ 2019-11-14 2 © Daniel Page [email protected] h i MATHEMATICAL PRELIMINARIES In Mathematics you don’t understand things. You just get used to them. – von Neumann The goal of this Chapter is to provide a fairly comprehensive overview of theory that underpins the rest of the book. At first glance the content may seem a little dry, and is often excluded in other similar books. It seems clear, however, that without a solid understanding of said theory, using the constituent topics to solve practical problems will be much harder. The topics covered all relate to the field of discrete Mathematics; they include propositional logic, sets and functions, Boolean algebra and number systems. These four topics combine to produce a basis for formal methods to describe, manipulate and implement digital systems. Readers with a background in Mathematics or Computer Science might skip this Chapter and use it simply for reference; those approaching it from some other background would be advised to read the material in more detail. 1 Propositional logic Definition 0.1. A proposition is a statement whose meaning, termed the truth value, is either true or false (less formally, we say the statement is true if it has a truth value of true and false if it has a truth value of false). A given proposition can involve one or more variables; only when concrete values are assigned to the variables can the meaning of a proposition be evaluated. -
