A mechanical or physical pointing device whose location
is associated with the position of the on-screen cursor. For example, if the
user of a graphics tablet places the pen on the upper right corner of the
tablet, the cursor moves to the upper right corner of the screen or on-screen
window associated with the pen. See also absolute coordinates.

Why need calendar program?
An application program in the form of an electronic
calendar, commonly used for highlighting dates and scheduling appointments. Some
calendar programs resemble wall calendars, displaying dates in blocks labeled
with the days of the week; others display dates day by day and enable the user
to enter appointments, notes, and other memoranda. A day-of-the-week type of
calendar program could,
for example, be used to find out that Christmas 2003 will be on a Saturday. Depending on its capabilities, such a program might cover only the current century, or it might cover hundreds of years and even allow for the change .
A calendar/scheduler program might show blocks of dates or, like an appointment book, single days divided into hours or half hours, with room for notes. Some programs allow the user to set an alarm to go off at an important point in the schedule. Other programs can coordinate the calendars of different people on the same network so that a person entering an appointment into his or her calendar also enters the appointment into a colleague’s calendar

Why B2B website needed?
Short for business-to-business. The
electronic exchange of products and services between businesses without the
direct involvement of consumers. B2B’s effects on business include streamlining
purchasing, accounting, and other administrative functions; lowering transaction
costs; and simplifying the sale of excess inventory. Related businesses have
collaborated on the creation of Internet-based supply-chain networks.
B2c:The direct electronic exchange of products and services between businesses and consumers. B2C’s effects on business include improving the efficiency in delivering goods and services to consumers.

What is ActiveX
A set of technologies that enables software components to
interact with one another in a networked environment, regardless of the language
in which the components were created. ActiveX, which was developed by Microsoft
in the mid 1990s and is currently administered by the Open Group, is built on
Microsoft’s Component Object Model (COM). Currently, ActiveX is used primarily
to develop interactive content for the World Wide Web, although it can be used
in desktop applications and other programs. ActiveX controls can be embedded in
Web pages to produce animation and other multimedia effects, interactive
objects, and sophisticated applications.
ActiveX control : A reusable software component based
on Microsoft’s ActiveX technology that is used to add interactivity and more
functionality, such as animation or a popup menu, to a Web page, applications,
and software development tools. An ActiveX control can be written in any of a
number of languages, including Java, C++, and Visual Basic.

What is Active Server?
The server-based component of Microsoft’s Active
Platform. Comprised of a set of technologies that includes DCOM (distributed
component object model), Active Server Pages, Microsoft Transaction Server, and
message queues, Active Server provides support for developing component-based,
scalable, high-performance Web applications on Microsoft Windows NT servers.
Active Server is designed to allow developers to concentrate on creating
Internet and intranet software in a variety of languages without having to focus
on the intricacy of the network itself. See also Active
Desktop, Active Platform, Active
Server Pages, ActiveX..
Active Server Pages :-. A Web-oriented technology developed by Microsoft that is designed to enable server-side (as opposed to client-side) scripting. Active Server Pages are text files that can contain not only text and HTML tags as in standard Web documents, but also commands written in a scripting language (such as VBScript or JavaScript) that can be carried out on the server. This server-side work enables a Web author to add interactivity to a document or to customize the viewing or delivery of information to the client without worrying about the platform the client is running. All Active Server Pages are saved with an .asp extension and can be accessed like standard URLs through a Web browser, such as Microsoft Internet Explorer or Netscape Navigator. When an Active Server Page is requested by a browser, the server carries out any script commands embedded in the page, generates an HTML document, and sends the document back to the browser for display on the requesting (client) computer. Active Server Pages can also be enhanced and extended with ActiveX components.

LG L80-the magic
optically discern how the upcoming mid-range looks akin to. We got images of the dual SIM
version of the L80, which comes with four capacitive touch buttons - back, home, menu and
multi-tasking at the front. We postulate the single SIM L80 will feature a physical home
button as visually perceived in the earlier trio.

Relational Databases-MySQL
MySQL is a relational database.
An important feature of relational systems is that a single database can be
spread across several tables as opposed to our flat-file phone book example.
Related data is stored in separate tables and allows you to put them together by
using a key common to both tables. The key is the
relation between the tables. The selection of a primary
key is one of the most critical decisions you'll make in designing a new
database. The most important concept that you need to understand is that you
must ensure the selected key is unique. If it's possible that two records past,
present, or future share the same value for an attribute, don't use them as a
primary key. Including key fields from another table to form a link between
tables is called a foreign key relationship, like
a boss to employees or a user to a purchase. The relational model is very useful
because data is retrieved easier and faster.
Relationship Types
Databases relationships are quantified with the following
categories:
-
One-to-one relationships
-
One-to-many relationships
-
Many-to-many relationships
We'll discuss each of these relationships and provide an
example. If you think of a family structure when thinking about relationships,
you're ahead of the game. When you spend time alone with one parent, that's a
specific type of relationship; when you spend time with both your parents,
that's another one. If you bring in a significant partner and all of youyour
parents, you, and your partnerall do something together, that's another
relationship. This is identical to the bucket analogy. All those different types
of relationships are like specific buckets that hold the dynamics of your
relationships. In the database world, it's the data you've created.
In a one-to-one relationship, each item is related to one and only one
other item. Within the example of a bookstore. A one-to-one relationship exists
between users and their shipping addresses.
Normalization
Thinking about how your data is related and the most efficient
way to organize it is called normalization. Normalization of data is breaking it apart based on the
logical relationships to minimize the duplication of data. Generally, duplicated
data wastes space and makes maintenance a problem. Should you change information
that is duplicated, there's the risk that you miss a portion and you risk
inconsistencies in you database.
It's possible to have too much of a good thing though:
databases placing each piece of data in their own tables would take too much
processing time and queries would be convoluted. Finding a balance in between is
the goal.
While the phone book example is very simple, the type of data
that you process with a web page can benefit greatly from logically grouping
related data.
Let's continue with the bookstore example. The site needs to
keep track of the user's data, including login, address, and phone number, as
well as information about the books, including the title, author, number of
pages, and when each title was purchased.
LG G3 screenies-come
is very clean and flat, a trend that a lot of manufacturers are embracing. Everything from the icons, launcher and notification drawer is less cluttered and looks very nice. The quick settings toggles are rounded icons, similarly to the latest Samsung TouchWiz UI on the Galaxy S5. The position of the QSlide Apps
remains unchanged, but still, the notification drawer seems too busy for our taste. Here's a full resolution screenshot for you to gaze at, as we had to shrink the rest to a reasonable web-friendly size. LG G3 QHD resolution screenshot Unrelated to these screen caps, recent rumors claim the LG G3 is going to be based on the Japanese LG isai FL, which leaked a few days ago. The Japan-only smartphone sports a quad-core Snapdragon 801 SoC, clocked at 2.5GHz, a 5.5-inch LCD rumored to have 2560x1440 resolution, 2GB RAM, 32GB internal memory with microSD support, 3000mAh battery, and an IPX7 rating,
