HRM 3450 Lecture 10 Notes – Electronically Control
Introduction
• To electronically control the various input, output, and storage components.
• The software, both application and system, which provides instructions that tell the
hardware exactly what tasks are to be performed and in what order.
• The data that is being manipulated and processed.
• This data may be numeric, it may be alphanumeric, it may be graphic, or it may take
some other form
• But in all cases it must be representable in a form that the computer can manipulate.
• In modern systems, input entry, output display, and storage of the data and software
used for processing often take place at a location different from the computer where
the actual processing occurs.
• In many installations, actual processing is distributed among computer systems, with
particular results passed to the individual systems that require them.
• Therefore, we must also consider a fourth component
• The communication component, which consists of hardware and software that
transport programs and data between interconnected computer systems.
• The hardware and system software components make up the architecture of the
computer system.
• The communication component connects individual computer systems together.
• The data components, and also the application software, while fundamental to the
operation of the computer system, are supplied to the computer system by the user
• Rather than being a part of the architecture of the computer system itself.
• It is useful to note, however, that application software and data structure are often
considered as part of the overall system architecture when one considers the
architecture from the perspective of the organization.
• We explore this issue briefly
