oA database management system (DBMS)is system software for creating and managingdatabases.A DBMS makes it possible for end users to create, protect, read, update, anddelete data in a database.Application softwareis designed to perform specific tasks for the company (eg,Quickbooks®).Software is created using a set of commands, instructions and other syntax called aprogramming language.oSource codeis a collection of commands and instructions written in a programminglanguage.oAcompileris a program that converts source code into object code, which are theinstructions a machine understands (ie, 1s and 0s, or on-off).Centralized vs. Distributed ProcessingCentralized ProcessingIn the early days of computers, each device was so expensive that a company rarely had more thanone and all activity had to take place on that single computer.Although different people couldconnect to that single computer usingremote terminals, these were simply input and outputdevices (essentially equivalent to just the keyboard and monitor on a current desktop).All activityhad to take place on the one computer, known ascentralized processing.Distributed ProcessingToday, computers are so reasonably priced that, in many businesses, employees each are assignedtheir own computers.This allows the allocation of a large volume of tasks to different employeesand computers at different locations, known asdistributed processing.Since the data utilized bythe company is no longer on a single computer, it is necessary for them to be able to connect toeach other in some way to form anetwork.Networks in GeneralIn a computer network, computers are connected to one another to enable sharing of peripheraldevices, data, and programs stored on a file server.The networking of different computers allowsmore than just the transfer of information from one to another.It also allows one computer to beused to operate the other.Types of NetworksNetworks may involve any size group from two (as in the case of many home networks) to theentire world.
