PROCESSING

• The term software refers to the instruction that control the operation of the computer hardware it has three major functions:

• 1. it allows the effective application of hardware to problem solving

• 2.It allows efficient management of computer resource

• 3. it Is the inheritance between he user or organization and its stored information

Types of software

• System software

• Application software

Application software in one of three ways

• Individual programs: have a single purpose and a single function

• Integrated packages: combine a range if key software types. Such as word processing , spreadsheet….

• Software suites: combine a range of individual packages into a system that integrates the features from all packages but sill provide full functionality in each application

System software

• This allows the user to interact with the computer and the peripherals that plug into it

Components of system sofware

• 1. ram: contains a permanent instruction

• 2. device drivers: are programs that allows communication between the cpu and peripheral devices such as the mouse and the printer.

• 3.Operating system: are the collection of programs that perform and manage the function of the computer.

Application software

• Word processors: the most and widely used software

• Spreadsheet: allows you to organized numeric data on a worksheet or spreadsheet.

• Database management software: is a collection of structured data in which records related to a certain entity such as person, book or item of stock.

Database management structure

• Relational database: data is viewed as a collection of linked tables. They are linked through unique key that is commom to all of them.

Network model: this structure is very similar to hierarchical model except the possible for lower level to more than one parent level.

• Object oriented: this structure is s multi media approach in which the user navigates through the data stored by clicking on objects.

Desktop publishing ( DTP)

• Allows the user to produce complete publication using computer hardware and software.

Graphic software: painting, drawing, and photo editing

• Painting software: is generally used to create manually drawn bi mapped graphics which are formed by series of dots called pixels.

• Drawing programs: allows free hand drawing and object manipulation

• Photo editing: allows image manipulation at very sophisticated level

CAD/CAM

Computer aided design is now common place in many architectural, mapping, mechanical, and engineering organization. It is used in highly technical graphic drawing

Presentation graphic

• Software that has been around for more than a decade demand from the business community promoted its development and use. it helps us efficiently of organized the information and effectively communicate with others.

Personal information managers PIM

• Is one of the newest and fastest growing software areas it integrates all the features of hand written diary or organizer as well as man automated information management tools into a system that promises to organize every part of your life.

Groupware

• Enables work related task to be coordinated throughout a network as way as increasing team productivity

Project management

• Project management involves planning organizing directing, controlling resources (such as equipment and people) to meet objective by set of date within the budget

Multi media authoring tools

• Combines a range of media ( data types) including sound, graphics, text, animation, and video into an east friendly environment.

communications

• electronic mail, or e mail as it commonly called, involves the communication of data over a network.

Web browser

• A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web.

Web development software

• One of the growth publishing areas in web publishing. Many organization are now in the internet or are in the process of doing so. This is becoming a very important communication medium for many organization.

Programming language environment

• Underlying software is a programming language. Programming languages send messages to the CPU as each action is required. However they can be used in independently of the software.
