What is Software? Computer software, or simply software, is a collection of data or computer instructions that tell the computer how to work.<br>
04
Define these two major categories of software Application software is a program or group of programs designed for end users. It includes applications such as database programs, word processors and spreadsheets.<br>
05
Define these two major categories of software (Cont.) System software is a type of computer program that is designed to run a computer's hardware and application program. The interface between the hardware and user applications.<br>
06
Types of system software An Operating System is system software that manages computer hardware, software resources, and provides common services for computer programs.
Utility Software is software designed to help to analyze, configure, optimize or maintain a computer. It is used to support the computer infrastructure - in contrast to application software, which is aimed at directly performing tasks that benefit ordinary users.<br>

The Types of User interfaces Graphical User Interface (GUI): The user interacts with menus and icons. Command Line Interface (CLI): The user types commands at a prompt. Most operating systems include both a GUI and a CLI.<br>
23
The User interface Command driven
Uses the keyboard to type commands into a window display
Very basic and intended to be purely functional
Need to know the correct syntax for giving commands
Used by computer experts Graphic User Interface

Aim/Topic: To introduce Computer software Software refers to the programs that make the computer function and enable it to carry out many different tasks.
Programs are sets of instructions that tell the computer how to carry out these tasks
System software controls the hardware and how it works. System software includes operating systems, translators and utilities.
When you start up a computer, you are booting it. The booting instructions are contained in the ROM chip. During booting, the computer looks for the operating system.<br>

Main Memory RAM stores data temporarily while the computer is being used
ROM stores data permanently, such as data to start up a computer<br>

32
Utilities Utility programs or utilities are usually bundled with an operating system. They maintain and protect the operating system. Listed are some tasks performed by utility programs
Manage files by renaming, sorting, listing , backing up, recovering and deleting them
Perform disk formatting which may include clearing a hard disk and reprogramming it form scratch
Scan and defragment a hard drive; this reorganize the hard disk for better memory management
Scan for viruses on a hard disk and remove any viruses that are found<br>

33
Application software Application programs or application software are programs that allow a computer to carry out specific tasks but they are not essential for the computer to work. If you want to use a computer to create documents, you need an application program for word programming.<br>
34
Types of application, Uses and Example<br>
35
General purpose General purpose application software is popular software that can be used by most people for many different purposes. Word processing applications are general purpose, because they are used for many reasons by people business and professionals. General purpose software is often fairly cheap and reliable because it has been used and developed by many people over the years.<br>
36
Special purpose Special purpose application software is designed for specific tasks or industries. It does not have much use beyond those task. For example accounting software is used for creating and maintaining accounting records. It is useful only to accountants or people in the accounting industry. Because it has a very specific market, special purpose software can be quite expensive.<br>
37
Custom written Custom written software is often called tailor made or bespoke software. It is written for a few owners or users to perform specific tasks. Custom written software is often used to modify general purpose software so it can do extra tasks. For example, custom written macros for Microsoft Excel can automate some spreadsheets tasks.<br>
38
Integrated software Integrated software is a set of useful application that are bundled together or sold together as one package. For example; Microsoft Office is an integrated software package of seven application programs. Word, Excel, Access, PowerPoint, Publisher, Outlook and FrontPage
Integrated software is often a cost-effective way of buying applications because you can get several applications for a good price.<br>
