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.

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.

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.
