Is a primary hardware component where the actual processing of data occurs.
Central Processing Unit
The CPU includes
primary storage, a control unit and an arithmetic/logic unit.
The best definition of the primary storage of the CPU is
The temporary main memory portion of the CPU that holds the program, data and results during processing -
The function of the control unit of the CPU is to
Control and directs the operation of the computer by reading or interpreting the program instructions and directing the computer in the execution of those instructions
The arithmetic/logic unit of the CPU:
Is the circuirty that performs the arithmetic calculations and logical operations
The primary storage is the temporary main memory portion of the CPU consisting
of both RAM (Random Access Memory) and ROM (Read Only Memory)
Forms of procedural languages are:
FORTRAN, COBOL and BASIC
A third generation language that allows programmers to concentrate on the procedures and functions of the programs is
Procedural languages
FORTRAN (FORMula TRANslation) was designed for
scientific purposes
COBOL (Common Business Oriented Language) was designed for
business operations
BASIC (Beginner All purpose Symbolic Instruction Code) was designed for
educational purposes
A patch is
a change or modification to an existing program
manages and schedules application programs and system functions

What are examples of Operating System(O/S)
Windows, Unix and Linus, MVS and DOS
is a command language that initiates programs, specifies processing priorities, running sequences, databases used and files used
Job Control Language or JCL
designed to perform a specific process or series of tasks.

is in a separate location from the company’s data center and has all of the hardware and software needed to begin operations
A hot site
Information systems process data and transactions within a business organization. These actions include
- Collecting and entering transactions and data
- Processing data and providing users with the information that they need to run the business
