Software
Task.
My task is to specify different types of software for 3 different systems.
Software comes on disks. You can't physically touch software. Software fits into two main categories.
* Operating systems (o/s)
* Applications (apps)
The operating system is the first thing that is loaded when the computer is turned on. All programs have to talk to the o/s. All desktop computers need an operating system.
The main things that the system software does is:
* It manages the hardware and software resources of the computer system. These resources include things like CPU, memory,
* It provides a suitable consistence way of applications to deal with hardware without having to know the details of the hardware.
* To make it easier to run user programs
* To improve the performance of the computer system
* To provide assistance with program development
* To simplify the use of the computer system for users other than computer specialists.
Operating systems fit into four main categories:
Real time operating system - These systems are used to control machinery, scientific instruments and industrial systems. This type of system has very little user interface capabilities. A very importance part of an RTOS is managing the resources of a computer so particular operations carry out in exactly the same amount of every time it occurs. In a complex machine, having a part move more quickly just because it has more resources available may just be as tragic as having it not move at all because the system was busy.
Single user, Single Task - This operating system is designed to manage computers so that one user can effetely do one thing at a time. An example of this is an operating system for a palmtop.
Single user, Multi Tasking - This is the type of operating system most people use on there desktops and laptops. An example of this is windows 98. This o/s will let a single user have several programs running at the same time. E.g. a person can be using a word processor and downloading some music of the Internet.
Multi user -. Allows multiple users to utilize the computer and run programs at the same time. Windows NT is an example of this type of o/s.
There are two types of o/s
* GUI graphical user interface
* Command line interface
Graphical user interface
Windows is a GUI. These programs are fairly easy to use because you don't have to lean the commands. They are user friendly. GUI generally characterised by the use of windows, icons, drop down menus, and a pointing device like as a mouse. The first company the created GUI was Xerox. The firs project that would have been the first commercial GUI was Lisa but the project had to be cancel because it was too expensive to make the program. The Mac was the product
Command line interface CLI
Dos is a CLI. In these types of operating systems the user has to memorise the language. You have to type in the command with the keyboard. This was a difficult o/s to use because not every one knows the commands and the language.
Windows is a GUI operating system. The biggest software company in the world, Microsoft, makes windows. There are many types of operating system that are used for different tasks. An example is Windows NT is used for networking computer together, and Windows 95 is used for computers that are not networked.
Windows is used on most computers systems. Windows is very easy to install and it is very user friendly this is why windows is very popular. The good thing about windows is that it has virtual memory; this is when some of you storage space in your hard disk drive is used to store temporary information. Most applications are made for windows because it is used on most machines. Windows also support all sorts of hardware.
Application software is software that uses an operating system to work. Application software and the operating system both communicate with each other. This type of software is made for a specific use. Word processing, database programs and communication programs are all example of application software.
Word processing application is a program that enables you to type. You can type letters, memos and a lot of other things.
All word processing applications can do the following:
* Insert text: Allows you to insert text anywhere in the document
* Delete text: Allows you to erase characters, words, lines, or pages as easily as you can cross them out on paper.
* Cut and past Allows you to remove (cut) a section of text from one place in a document and insert (past) it somewhere else
* Copy: Allows you to duplicate a section of text.
* Page size and margins: Allows you to define various page sizes and margins, and the word processor will automatically readjust the text so that it fits.
Typing software
This is a software package that helps the user type faster without making any errors.
