Comparison of Primary Storage Devices & Secondary Storage Devices.


The storage devices are broadly classified into secondary storage and primary storage. The secondary storage is known as peripheral storage, and is used to stores information of the computer that is not in current use. The secondary storage is typically slower and is of higher capacity than primary storage. The secondary storage is almost non – volatile. The secondary storage is slow due to serial access.

The primary storage is used to refer for local random access disk storage and is properly called secondary storage. If this type of storage is called primary storage, then the term secondary storage would refer to offline. This usually occurs in the slower, larger forms of storage which is used to develop vendors to provide secure device management services, authentication services, as well as encryption for data. There is software and application based solutions; however software – based encryption solutions can impact performance during the storage process. Vendors provide hardware based solutions, which are appliances that provide authentication to protect the data. These devices are taken into account for the different requirements of securing data on primary or secondary storage. The primary storage performance and access specifications for the tape environment and requires the encrypting to tape would require integration with backup schemas for primary storage scenarios.

simple structure of a processor



Describe generally about total computer system & computer networking


A total computer system is comprised of many internal and external devices. The complete computer made up of the CPU, memory and related electronics (main cabinet), all the peripheral devices connected to it and its operating system. Computer systems fall into two broad divisions: clients and servers. Client machines fall into three categories from low to high end: laptop, desktop and workstation. Servers range from small to large: low-end servers, mid range servers and mainframes.
A computer network is a group of computers that shares information across wireless or wired technology. Computer networks used to only be available for corporations but they are affordable for small businesses and individuals. Computer networking requires two computers, a protocol and the hardware to connect them. Collection of two or more computers that are interconnected with each other to perform data communication using the data communication protocol through communications media (wired or wireless), so these computers can share information, data, programs, and use of hardware together.

Benefits of Adobe Dreamweaver


Browser Development - Dreamweaver is the only web design software that develops web pages that can be viewed by all web browsers.
Quick Development Time - By incorporating easy-to-create templates as well as a reusable page library, Dreamweaver can be used by experienced developers to create a robust web site quickly.
Data Processing - By using Spry Data and Java scripting to handle dynamic data, Dreamweaver replaces back - end databases.
Table less Layouts - Dreamweaver offers table less layouts for web pages. Images and text no longer need to be placed in tables.
Split Development Screen - Dreamweaver 8 offers the developer a split screen. Half the screen displays the code for using HTML and the other half of the screen is a visual representation allowing for WYSIWYG (What You See Is What You Get) development.

Features of Adobe Dreamweaver

1.     Spry framework for Ajax - With Adobe Dreamweaver, you can visually design, develop, and deploy dynamic user interfaces using the spry framework for Ajax. The Spry framework for Ajax is a JavaScript library for web designers that allow designers to build pages that provide a richer experience for their users. Unlike other Ajax frameworks, Spry is accessible to both designers and developers alike, as 99% of it is actually HTML.
2.     Spry widgets - Spry widgets are prebuilt, common user interface components that you can customize using CSS, and then add to your web pages. With Dreamweaver, you can add a number of spry widgets to your pages, including XML-driven lists and tables, accordions, tabbed interfaces, and form elements with validation.
3.     Spry effects - Spry effects are a simple, elegant way of enhancing the look and feel of your website. You can apply them to almost any element on an HTML page. You can add Spry effects to enlarge, shrink, fade, and highlight elements; visually alter a page element for a certain period of time; and more.
4.     Advanced Photoshop CS3 integration - Dreamweaver includes enhanced integration with Photoshop CS3. Now, designers can simply select any portion of a design in Photoshop even across multiple layers and paste it directly into a Dreamweaver page. Dreamweaver presents a dialog box where you can specify optimization options for the image. Should you ever need to edit the image, simply double click the image to open the original layered PSD file in Photoshop for editing.
5.     Browser Compatibility Check - The new Browser Compatibility Check feature in Dreamweaver generates reports that identify CSS-related rendering issues in a variety of browsers. In code view, issues are flagged with green underlining, so you know exactly where the problem is. After you identify the problem, you can quickly fix it if you know the solution.
6.     Adobe CSS Advisor - The Adobe CSS Advisor website contains information on the latest CSS issues, and is accessible directly from the Dreamweaver user interface during the Browser Compatibility Check process. More than a forum, a wiki page, or a discussion group, CSS Advisor makes it easy for you to comment with suggestions and improvements to existing content, or to add new issues for the benefit of the entire community.
7.     Manage CSS - The Manage CSS feature makes it easier for you to move CSS rules from document to document, from the head of a document to an external sheet, between external CSS files, and more. You can also convert inline CSS to CSS rules, and place them where you need them just by dragging and dropping.

What are the five main views in Microsoft Outlook?

  • Mail
  • Calender
  • Contacts
  • Tasks
  • Notes

How do you manage multiple e-mail accounts in Microsoft Outlook?


1.      Outlook can manage all your e-mail account for you, becoming one central place to work with all your messages.
a.      Sending Messages from Multiple Accounts.
When you are sending messages, you are in control of which account Outlook uses. You can tell Outlook to use a different account.
·        When you create a new message, Outlook assumes you’ll want to use the default account to send it unless you specific a different account.
·        If you are replying to a message, Outlook uses the account that the message came in on. If you receive a message sent to your account, and you click Reply or Reply to all, Outlook would assume you want to send the reply using that account.
·        When you forward a message, Outlook will assume you want to do so using the same account as the original message.
·        You tell Outlook which e-mail account to use when you have the message window open. When you have multiple accounts set up, you will see an Account Button below the Send Button. Click the account button, and Outlook will display a menu containing all your e-mail accounts. Select one, and Outlook uses that one to send your message.
b.      Changing the Default Account.
·        You may sometimes decide that you want Outlook to use a different e-mail account as your default. If you want to change the default, follow these steps:
                                                                    I.            Go to the main Outlook menu and click Tools>Account Settings to open the Account Setting dialog box.
                                                                  II.            On the e-mail tabbed page of the Account Setting dialog box, find the box listing all your e-mail accounts. Click the account you want to make your new default account.
                                                                III.            In the space above the account list, find and Click Set as Default. Outlook dims this option until you select a new account to use as default.
                                                               IV.            The list rearranges itself so the new default option appears at the top of the list.
                                                                 V.            Click Close.

·        Another step to change default account:
                                                                                I.            Go to control Panel.
                                                                              II.            Click on User Accounts and Family Safety.
                                                                            III.            Click on mail.
                                                                           IV.            Click on E-mail accounts.
                                                                             V.            Click the account you want to make your new default account.

How do you save the Contact from an email message you receive?


To save an e-mail address, name, or other contact information from an e-mail message that you receive, you add it to your Microsoft Outlook contacts. After this information is added to Contacts, it is automatically included in your Outlook Address Book.
In a message that you receive, right-click the name of the sender, and then click Add to Outlook Contacts.
A contact form opens, with the sender’s name and e-mail address already filled in.
Click Save and close.
After it is added to your main Outlook Contacts folder, which is the default contact folder displayed in the Outlook Address Book, the contact can be copied to any other Contact folders you have created. New contact folders are automatically added to the Address Book, and the new information is also available to you there.

Briefly explain Information viewer, Drafts, Search box, Navigation pane?


  1.  Information Viewer.
The Information viewer is where most of the action happens in Outlook. When you are reading email, you look in the Information Viewer to read your message; if you are adding or searching for contacts, you see contact names here. The Information Viewer is also where you can do all sorts of fancy sorting tricks that each module in Outlook lets you perform. Also you can browse calendar data in the Information Viewer.
  2.   Drafts.
Draft will save the message until you finish composing. You don’t have to send every message right way, just save it in Draft and finish it later on.
Draft folder is used for keeping work in progress. If you are sending an e-mail to someone and you don’t have all the information available to finish the e-mail off then you can save it to Drafts. By saving an e-mail to Draft you can come back to it later at your convenience.
  3.  Search box.
Outlook 2007 offers a new search tool, called instant search. Near the top of the Information Viewer pane, in the centre of the screen, you see the instant search box. This box has a little magnifying glass on the right and some text on the left. Click the box and type the 1st few letters of a word that you want to find. Almost immediately, the Information Viewer screen goes blank, and then shows only the items containing the text you entered. When outlook displays the items it found, the magnifying glass is replaced byû. Clear the search result by clicking theû.
  4.     Navigation Pane.
The Navigation Pane, located next to the main window, is made up of 2 areas.
·       An expandable folder list that provides access to your personal Microsoft Office Outlook Web Access folders and any folders you create. The folders are displayed in a hierarchy that you can expand to view the folder contents or collapse to view only the top-level folder. The plus sign icon next to a folder indicates that the folder contains sub folders. To view the sub folders, click the plus sign.
·        A set of buttons that provide one click access to your inbox, calendar, contact, and Task folders and to your organization’s public folders. An options button allows you to set user option, such as calendar or task reminder. A horizontal splitter bar located between the folder list and the buttons allow you to collapse the button into a button tray. When you click any folder or button in the Navigation Pane, it contents are displayed in the outlook Web Access main window.

How do you create a setup application to distribute your application


Before we can distribute our application, we must build an application file with an .app extension, an executable file with an .exe extension, or a COM component (automation server) with a .dell extension.
Prior to building our application, make sure that our project includes the necessary files for our application, as well as any resource files, such as graphics files or templates. For more information about the types of files we can include in our application, see "Including Resources in Applications" in the Visual FoxPro online Help.
The development environment of Visual FoxPro contains many features and files that are licensed for our use only. If our application contains any of these features or files, we must remove them from our application before creating our Setup program. For a list of redistributable files, see Redist.txt, located in our Visual FoxPro directory (C:\Program Files\Microsoft Visual FoxPro 7) and "Removing Restricted Visual FoxPro Features and Files" in the Visual FoxPro online Help.
When we choose the type of build we want to create, consider the size of our final application file and whether users have Visual FoxPro installed on their computers.
  • Application (.app) file   this file requires that the user have a copy of Visual FoxPro installed. An .app file typically is smaller than an .exe file.
  • Executable (.exe) file   this file includes the Visual FoxPro loader, so users are not required to have Visual FoxPro installed.
  • COM Server (.dull) files   Used to create a file that can be called by other applications.
Some distribution scenarios might require merge modules in addition to the Visual FoxPro run-time files.

Three options that deployment wizard offers


  • The Package option helps we package a project's files into a .cab file that can then be deployed, and in some cases creates a setup program that installs the .cab files. The wizard determines the files we need to package and leads us through all the choices that must be made in order to create one or more .cab files for our project.
  • The Deploy option helps we deliver our packaged applications to the appropriate distribution media, such as floppies, a network share, or a Web site.
  • The Manage Scripts option lets we view and manipulate the scripts we have saved from previous packaging and deployment sessions in the wizard. Each time we use the wizard, we save a script that contains all the choices we made. We can reuse these scripts in later sessions if we want to use similar settings and make the same choices as we did previously.

Exe Files


An exe file is a file that ends with the extension ".exe" otherwise known as an executable file. When one clicks on an exe file, a built-in routine automatically executes code that can set several functions into motion. Exe files are used to install and run programs and routines.
An exe file is just one of several types that are recognized by various operating systems. Text files, which are files that do not generate code but simply display text, end in txt. Microsoft Word saves files with the doc extension, short for document. Another common file type is the compressed or zipped file, which uses the zip extension.
The exe file is one of the most useful types of files precisely because it runs programs; however, this also makes it potentially harmful. It can be used as a delivery system for viruses or other malicious routines. Outwardly, the infected exe file might seem quite benign. Clicking on it might appear to launch nothing more than an animated cartoon or simple arcade game. However, unseen code can be running in the background, infecting or compromising the computer.
