PowerPoint Presentation On Mozilla Firefox

PPT On Mozilla Firefox


Mozilla Firefox Presentation Transcript:
1. What is Firefox?
Mozilla Firefox is a free, open source, cross platform, graphical web browser developed by the Mozilla Corporation. Firefox includes an integrated pop-up blocker, tabbed browsing, live bookmarks, support for open standards, and an extension mechanism for adding functionality. Although other browsers have introduced these features, Firefox became the first such browser to achieve wide adoption.

2. Where can I get Firefox?
You can get the most recent version of Firefox (1.5) from the Official Mozilla Firefox site, ( To get previous versions of Mozilla Firefox, go to

3. Why choose Firefox?
The browser has a number of features which help users find information. First, it has a find as you type feature. It also has a built-in search toolbar. You can customize Firefox through extensions. Extensions activate new features. Extensions can be easily updated through the Mozilla Update website. Firefox also supports themes/skins, which change the appearance. Firefox is also cross-platform. It can be used on Windows, Mac OS X, Linux and other small Operating Systems. It can also be used on a USB Flash Drive with a Portable Version of Firefox.

4. Who made Firefox?
The Mozilla Corporation made the Firefox browser. The Mozilla Corporation is a wholly owned subsidiary of the Mozilla Foundation that develops, distributes and promotes the Internet-related applications, including the Mozilla Firefox web browser and the Mozilla Thunderbird email client.

5. How did Firefox become how it is now?
Firefox has developed considerably since its first release as Phoenix on September 23, 2002. Pre-1.0 releases suffered many issues with extensions, as the code for handling them changed from version to version. Throughout its development, Firefox versions have had internal codenames. “Deer Park" was originally destined to become Firefox 1.1. However, Mozilla Foundation decided to change the version number of the next major release from "1.1" to "1.5", since it contained more new features than originally planned. In an attempt to dissuade end-users from downloading the preview versions, "Deer Park" versions do not use the standard Mozilla Firefox branding. On November 29, 2005, Firefox 1.5 was officially released.

6. Statistics About Firefox?
With over 25 million downloads in the 99 days after the initial 1.0 release, Firefox became one of the most downloaded free and open source applications, especially among home users. On October 19, 2005, Firefox had its 100 millionth download, just 344 days after the release of version 1.0. Firefox 1.5 was released on November 29, 2005, with more than 2 million downloads within the first 36 hours. On March 21, 2006, Mozilla released the first alpha version of Firefox 2.0 under the name of Bon Echo Alpha 1, with all Firefox branding, including icons, removed to discourage end-users from downloading it.

7. Firefox Future Development?
According to the roadmap, future Firefox development will include version 2.0 and version 3.0. Development for version 2.0 will occur on the 1.8 branch from which version 1.5 was released, with release coming off of the yet-to-be-created 1.8.1 branch, while development on version 3.0 occurs simultaneously on the Mozilla trunk. Mozilla is developing versions 2.0 and 3.0 simultaneously in order to ship front-end innovation in version 2.0 built on a more stable back-end, while completing major architectural changes for version 3.0. The development name for Mozilla Firefox 2.0 is Bon Echo. The alpha (2.0a1) version became available on March 21, 2006, and, according to Mozilla, is aimed primarily at the developer and testing community. There are still some bugs present, so any downloads of Bon Echo should be taken with a grain of salt.

PPT On Prepaid Energy meter


Prepaid Energy meter Presentation Transcript:
A scheme of Electricity billing system called “PREPAID ENERGY METER WITH TARIFF INDICATOR” can facilitate in improved cash flow management in energy utilities and can reduces problem associated with billing consumer living in isolated area and reduces deployment of manpower for taking meter readings


In our project we have given the name for memory card as smart card. When the consumer insert a smart card into the card reader which is connected in “prepaid energy meter with tariff indicator”kit.Then the card reader will read the stored information and delete the information from the EEPROM IC(smart card) using the MC program. So that the smart card cannot be reused by others. Suppose if a consumer buy a card for Rs.50/- he / she can insert this amount through the card reader so that prepaid energy meter with tariff indicator kit will be activated. According to the power consumption the amount will be reduced. When the amount is over, the relay will automatically shutdown the whole system.

PowerPoint Presentation On Software Testing

PPT On Software Testing


Software Testing Presentation Transcript:
1. What is Testing??
“Testing is the process of executing a program with the intent of finding errors”. It is a process of evaluating a system by manual or automatic means and verifying that it satisfies specified requirements or identify differences between expected and actual results.

2. Why Software Testing
It is important as it cause impact on operational performance and reliability if not done properly. Effective software testing helps to deliver quality software products that satisfy user’s requirements, Needs and expectations. If done Poorly, it leads to high maintenance cost and user dissatisfaction

3. Why Software Testing
It is important as it cause impact on operational performance and reliability if not done properly. Effective software testing helps to deliver quality software products that satisfy user’s requirements, Needs and expectations. If done Poorly, it leads to high maintenance cost and user dissatisfaction

4. Verification & Validation (V&V)
Verification – Are we developing a product right? Validation – Are we developing the right product ? It is the difference between 'What and How' Two types of V &V is there Static V & V Dynamic V & V

5. Principles of Software Testing
Testing is the process of executing a program with an intent of finding error and it should be planned long before testing begins. Test cases must be written for invalid and unexpected, as well as for valid and expected input conditions. A good test case is one that has high probability of detecting an error.

6. Principles of Software Testing….
All the test cases should be traceable to the customer requirements Testing should be planned long before testing begins Testing should begin 'in small' and process towards testing 'in large' To be most effective, testing should be conducted by independent third parties.

7. Purpose and Benefit Testing
The main objective of testing is to help clearly describe system behavior and to find defects in Requirements, design, documentation, and code as early as possible. The test process should be such that it should reduce the number of defects of the software product to be delivered to the customer. All tests should be traceable to customer requirements.

8. Programmers don’t like to test WHY?
Testing is considered Low Tech Low excitement Suitable for people with lots of time on their hands Many programmers believe that once they have gone through the formality of running a few perfunctory tests against it, their code works When building an electronic circuit, a hardware designer goes over it carefully in several times before ever applying power For programmers, if a program happens not to crash and even generates output that looks like it might be correct, the programmer is tempted to believe that the program works

9. Objective of Software Tester
The goal of a Tester is to find defects. The goals of a Tester is to find Defects and find them as early as possible. The goal of a Tester is to find defects and find them as early as possible and make sure they get fixed.

PowerPoint Presentation On Holographic Versatile Disc

PPT On Holographic Versatile Disc


Holographic Versatile Disc Presentation Transcript:
1. Need Of HVD
Multimedia - a single minute of compressed video takes up to 12 Mbytes Data Warehouses - large corporations’ warehouses now taking more than 2 Tbytes World Wide Web - one vendor’s high-end Web server packs 128 Gbytes of disk In Hospitals Multi slice CAT scan: 500MB Cardiac video: 3GB

2. What is HVD ?
Holographic Versatile Disc (HVD) is an optical disc technology which would hold up to 3.9 terabytes (TB) of information . An HVD is an advanced optical disk that’s presently in the development stage. Polaroid scientist J van Heerden was the first to come up with the idea for holographic three-dimensional storage in 1960. Holographic memory systems have been around for decades. They offer far more storage capacity than CDs and DVDs -- even "next-generation" DVDs like Blu-ray -- and their transfer rates are far very less.

3. Basics of Holographic Disk
The first step in understanding holographic disk is to understand what "holographic" means. Holography is a method of recording patterns of light to produce a three-dimensional object. The recorded patterns of light are called a hologram.

4. A Holographic Disk can:
Store information throughout the whole volume of the medium instead of just the surface as with other storage technologies. Uses fewer or no moving parts at all, thus allowing greater data processing speeds. Hold more information than 100 compact disks of the same diameter Can read 64,000 bits at one time, compared to just one or two bits with magnetic storage. Provides unique robustness and error insensitivity

5. Advantages
1) Large Data Density/ Capacity Uses optics instead of read-write heads, and uses whole volume of medium instead of just surface as with conventional devices. 2) Better Reliability Uses less moving parts (or no moving parts) 3) High Transfer Rates & Short Access Times Parallel access instead of bit-by-bit access 4) Fault And Damage Tolerance Which Are Not Available Simultaneously With Any Other Storage Technology.

6. HVD Structure
Green writing/reading laser (532 nm) Red positioning/addressing laser (650 nm) Hologram (data) Polycarbon layer Photopolymeric layer (data-containing layer) Distance layers Dichotic layer (reflecting green light) Aluminium reflective layer (reflecting red light)

7. Working Principle HVD
uses a technology called 'collinear holography,' in which two laser rays, one is blue-green and another is red, are collimated into a single beam.. The blue-green laser reads data encoded as laser interference fringes from a holographic layer near the top of the disc while the red laser is used as the reference beam and to read servo information from a regular CD-style aluminium layer near the bottom. Servo information is used to monitor the position of the read head over the disc, similar to the head, track, and sector information on a conventional hard disk drive.

8. HVD Write System
A simplified HVD system consists of the following main components: Blue or green laser (532-nm wavelength in the test system) Beam splitter/merger Mirrors Spatial light modulator (SLM) CMOS sensor Polymer recording medium

9. When the blue-green argon laser is fired, a beam splitter creates two beams. One beam, called the object or signal beam, will go straight, bounce off one mirror and travel through a spatial-light modulator (SLM). An SLM is a liquid crystal display (LCD) that shows pages of raw binary data as clear and dark boxes. The information from the page of binary code is carried by the signal beam around to the light-sensitive lithium-niobate crystal. Some systems use a photopolymer in place of the crystal. A second beam, called the reference beam, shoots out the side of the beam splitter and takes a separate path to the crystal. When the two beams meet, the interference pattern that is created stores the data carried by the signal beam in a specific area in the crystal -- the data is stored as a hologram.
