Introduction to the concept of software

Computer software, or simply software is any set of machine-readable instructions that directs a computer's processor to perform specific operations. Computer software contrasts with computer hardware, which is the physical component of computers. Computer hardware and software require each other and neither can be realistically used without the other. Using a musical analogy, hardware is like a musical instrument and software is like the notes played on that instrument.Users often see things differently from programmers. People who use modern general purpose computers (as opposed to embedded systems, analog computers and supercomputers) usually see three layers of software performing a variety of tasks: platform, application, and user software.



Platform software: Platform includes the firmware, device drivers, an operating system, and typically a graphical user interface which, in total, allow a user to interact with the computer and its peripherals (associated equipment). Platform software often comes bundled with the computer. On a PC one will usually have the ability to change the platform software. Application software: Application software or Applications are what most people think of when they think of software. Typical examples include office suites and video games. Application software is often purchased separately from computer hardware. Sometimes applications are bundled with the computer, but that does not change the fact that they run as independent applications. Applications are usually independent programs from the operating system, though they are often tailored for specific platforms. Most users think of compilers, databases, and other "system software" as applications.

1.From the HOME menu, tap on the System Settings Icon.



User-written software: End-user development tailors systems to meet users' specific needs. User software include spreadsheet templates and word processor templates. Even email filters are a kind of user software. Users create this software themselves and often overlook how important it is. Depending on how competently the user-written software has been integrated into default application packages, many users may not be aware of the distinction between the original packages, and what has been added by co-workers.



Installing/uninstalling a software

Installing Software When you purchase new software for your laptop, it may help to know that some applications will automatically start the installation setup once you insert the software CD in the DVD/CD-RW drive. Other packages, however, may require you to load the software from floppy disks. (Also, when purchasing software, make sure that the package is labeled for Windows PCs, and not for Macintosh computers.) To install software, open the Start menu and select the Run option. Type the letter of your CD drive in the window that appears, and click on Browse. Look for the setup.exe file in the list of files that should appear.




Uninstalling Software To uninstall a piece of software from your laptop, first open the Start menu and select the Control Panel option. In the Control Panel window that appears, double-click on the Add/Remove Programs icon. An Add/Remove Programs Properties window will appear. If the software you wish to remove appears in the list at the bottom of the window, click on the software you wish to delete to select it, then left-click on the Add/Remove button. Follow the prompts that appear on the screen to finish uninstalling the software.




If the software you wish to uninstall does not appear in the list at the bottom of the Add/Remove Programs Properties window, open the Start menu and select the Programs option. From the pop-up sub-menu that appears, select the name of the software you wish to remove, and see if there's an uninstall option available for that package. If so, click on the uninstall option and follow the prompts to finish uninstalling the software. Still other software packages require you to re-run the program's setup/installation procedure from the original media, in order to uninstall the software.



MS Paint

Many of you know that Paint is a drawing tool that can be used for simple drawings and basic image editing. Paint has been included in every version of Microsoft Windows, starting with Windows 1.0 which was released in 1985. After more than 20 years of development, Paint reached version number 6.1 in Windows 7 and 6.2 in Windows 8. Even though the version number is different between Windows 7 and Windows 8, the application is the same in both operating systems. But, compared to earlier versions of Windows, Paint has been changed and improved dramatically, after years of stagnation. It finally feels like a basic image editing tool worth taking into consideration.In this article we will show you where to find Paint, how to work with the new interface and which are the most important options and improvements.



Where To Find Paint in Windows 7 & Windows 8

You can find Paint by typing the word 'paint' in the search box of the Start Menu, in Windows 7, and directly on the Start screen, in Windows 8.


Alternatively, you can find it following this path: Start Menu -> All Programs -> Accessories -> Paint.

For those of you using the command line, you can find it at 'C:\Windows\System32\mspaint.exe'.


The Ribbon Is Present in Paint

After you open Paint you will see that the interface is completely modified compared to older versions. Now all the items are on the top side of the window. The new design uses the same concepts as the 'flow interface' from Microsoft Office 2007 and 2010. Therefore this group of users should be familiar with it and find their way very easily. For those of you who are not familiar with it, I will explain the most important elements.

The version of Paint in Windows 8 is almost identical to the version in Windows 7. The only difference is the fact that the interface looks flat and doesn’t have any transparency. All the options, features and menus are the same though. Therefore, I will be using the Windows 7 version in all my screenshots and explanations.




At the top of the window, on the titlebar, there is a Quick Access Toolbar with some of the most important buttons: Save, Undo and Redo.

If you click on the small arrow right next to the Redo button, a menu will open up which will allow you to customize the Quick Access Toolbar. You can add buttons like New (image), Open, Print or remove any of the existing ones. All you have to do is to click on the buttons you want to add or remove.




Under the title bar there is the main toolbar. The first button on the left side opens up the main menu of Paint, which is similar in options to the File menu from previous versions.

In this menu you can: "Open a new or existing image", Save an image, Print, "Acquire an image from a scanner or camera", "Send an image in e-mail", "Set as desktop background" the current image, see the Properties of the image and Exit Paint.




As in Microsoft Office, some menu items have extended options. For example, if you click on Save as, in the right pane of the menu you will see the most used formats for images: Bitmap, JPEG, GIF, and PNG.




Next, we have the Home tab with all the main image editing items that you would expect to see in Paint.

One of the things you can do is to add any of the tools from the Home tab to the "Quick Access Toolbar". Just right-click on the tool that you want to add and select "Add to Quick Access Toolbar" from the right-click menu.


In the next section of this article we will come back to this tab and explain the main options.



Next to the Home tab there is the View tab. Here you can Zoom In/Out or see an image in Full Screen mode. Also you can select to show Rulers and Gridlines on an image which can help you align elements in an image.




Finally, under the tabbed menu, there is the Drawing area and below it the Status bar where you can see general information about the current image.



The Home Tab - New Options & Features

Let’s get back to the Home tab. Here you will find most of the new options and features introduced by Paint. In this section I will try to walk you through them.The first section of the Home tab contains the Clipboard tools: Paste from, Copy and Cut. Then you have the Image section, with the Crop, Resize, Rotate and Select tools.

The selecting and resizing tools have been improved with two new options: now you can resize the picture by percentage or by pixels.




Also the selections have new options. When selecting parts of an image, you can decide if you want the background color to be included in the selection or not. Simply check or uncheck the "Transparent selection" option. If you want the background included, uncheck the option and vice-versa.




Finally, there are the Brushes and Shapes tools which also gained new options, shown in the screenshot below.



Adobe Reader

Adobe Reader software is the free trusted standard for reliably viewing, printing, and annotating PDF documents. It's the only PDF file viewer that can open and interact with all types of PDF content, including forms and multimedia.Note: In Reader, complete commenting tools are available only in PDFs that have commenting enabled. PDFs in a review workflow typically include commenting rights. You use annotation and drawing markup tools (Comment pane) to add comments. Comments are notes and drawings that communicate ideas or provide feedback for PDFs. You can type a text message using the Sticky Note tool. Alternatively, you can use a drawing tool to add a line, circle, or other shape and then type a message in the associated pop-up note.



Adobe Reader

Text-editing tools let you add editing marks to indicate changes that you want in the source document. Most commenting and markup tools don’t appear in the toolbar until you add them.

Note: If you open a PDF in a browser for a shared review that has ended, the commenting tools are unavailable.Most comments include two parts: the icon, or markup, that appears on the page, and the text message that appears in a pop-up note when you click or double-click the icon or place the pointer over the icon. After you add a comment, it stays selected until you click elsewhere on the page. Acrobat highlights a selected comment with a blue halo to help you find the markup on the page. A wireframe with selection handles appears on drawing markups and stamps, so that you can adjust the size and shape.

Show annotations and drawing markup tools

Annotations and markup tools don’t appear by default, except when you open a PDF in a managed review workflow. Click the Comment task pane button, and then click the Annotations or Drawing Markup panels.



Select an annotation or drawing markup tool

Choose Comment > Annotations > [tool]. Choose Comment > Drawing Markups > [tool].

Note: After you make an initial comment, the tool changes back to the Select tool so that you can move, resize, or edit your comment. (The Pencil and Highlight Text tools stay selected.)



Keep an annotation tool selected

You can add multiple comments without reselecting the tool.

Select the tool you want to use (but don’t use it yet). Right-click (Windows) or Control-click (Mac OS) and choose Keep Tool Selected.



Internet Browsers:

A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of content.[1] Hyperlinks present in resources enable users easily to navigate their browsers to related resources.Although browsers are primarily intended to use the World Wide Web, they can also be used to access information provided by web servers in private networks or files in file systems.The major web browsers are Firefox, Internet Explorer, Google Chrome, Opera, and Safari



Antivirus programs:

Antivirus or anti-virus software (often abbreviated as AV), sometimes known as anti-malware software, is computer software used to prevent, detect and remove malicious software.Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect from: malicious Browser Helper Objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious LSPs, dialers, fraudtools, adware and spyware.[1] Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity (privacy), online banking attacks, social engineering techniques, Advanced Persistent Threat (APT), botnets, DDoS attacks

Media player

A media player is a computer program for playing multimedia files. Media players display standard media control icons known from physical devices such as tape recorders and CD players. Examples of these icons are (play), (pause), and (stop).Mainstream operating systems have at least one built-in media player. For example, Microsoft Windows comes with Windows Media Player while Mac OS X comes with QuickTime Player. Linux distributions may also come with a media players, such as SMPlayer, Amarok, Audacious, Banshee, MPlayer, Rhythmbox, Totem, VLC, and xine.



Media player

General-purpose media players can play both audio and video; special-purpose players, however, focus on providing extended playback features for one media type. Such players are known as either audio players or video players and often have a user interface tailored for the specific media type. For example:

HTPC (Home Theater PC) software, features including media library and normally has a GUI (graphical user interface) with 10-foot user interface design and primary designed for display on a large television (or similar sized screen) with interaction using a regular television-style remote control.



Media player

Windows DVD Player is dedicated to playing DVD-Video discs.

MediaMonkey can play both audio and video but many of its features including media library, lyric discovery and music visualization are geared toward consumption of audio material such as songs and audiobooks.

Media Player Classic can play both audio and video but many of its features such as color correction, picture sharpening and subtitle support are only useful for video material such as films and cartoons.
