About Life

The acts of this life are the destiny of next.

We make a living…

What we have done for ourselves dies with us,

But what we have done for others remains forever.

We make a living by what we got,

But we make a life by what we give

Follow Your Dreams

Every great dream begins with a dreamer. Always remember, you have within you the strength, the patience, and the passion to reach for the stars to change the world.

 

 

Harriet Tubman

Happiness Quotes

When one door of happiness closes, another opens, but often we look so long at the closed door that we do not see the one that has been opened for us.
Helen Keller

Hub and Its Types

A common connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

A passive hub serves simply as a conduit for the data, enabling it to go from one device (or segment) to another. So-called intelligent hubs include additional features that enables an administrator to monitor the traffic passing through the hub and to configure each port in the hub. Intelligent hubs are also called manageable hubs.

A third type of hub, called a switching hub, actually reads the destination address of each packet and then forwards the packet to the correct port.

Apple iCup

iCup is an innovative concept specially designed for Apple. It’s key point that you can heat up any drink inside the cup by connecting it with the user’s notebook, as well as any device that supports USB connection, via a USB cable(in Park,at office,at library etc.) The key goal of the project is to ease life with more manageable features that ensure uninterrupted working opportunity, doesn’t matter the user goes to the park, library or working in the office. The featured Apple logo of the cup is actually a heat indicator that shows the temperature of the inside content, blue for cool, orange for warm and pink for hot, while enhancing the aesthetics. Moreover, it incorporates a displaceable handle that offers convenient fit into any small area and the changeable upper portion allows easy washing.

 Every part of the iCup from Onur Karaalioglu is enhanced with advanced technologies and innovative ideas. The Apple cup has got everything like a heatproof body which anyone can touch and hold while being connected to the netbook, a heat filter, allochrous logo for easy handling, a heat coil and a durable base. 

 A person, sitting in a library, in their office, in a park or while working at home on their netbook will not have to long for a hot cup of tea or coffee or will no longer have to keep ordering for a fresh cup every time when finding it getting cold. For heating up your drink this special cup named as the iCup would hopefully not just be a concept and will soon be available at the Apple store. The specialty of this cup is that it is easy to use, easy to connect and most importantly, easy to wash. For washing the iCup, one will just have to bring out the inner part of the cup as it is of removable kind. So, once the washing process is done and it gets dry, you can easily place it again in the heatproof body. For further ease of use, this Apple iCup has been designed with a removable handle too.
