Asked by Aryan Gusain in Computers & Technology at 10:18 AM on July 03, 2008

rOllEr's Answer

Frog’s breathe through their ski n when under water.
Breathing is a gas exchange, taking in oxygen from the surroundings and letting out carbon dioxide. After a frog breathes, the fresh oxygen is distributed throughout the body by the blood.
Frogs have three respiratory surfaces that is three areas of its body which can aid in gas exchange which are its skin, lungs, and the thin membranes lining its mouth and pharynx. The frog's first respiratory surface is the skin.
Frogs can breathe through their skin while they are in wet places like in water. They can also exchange gases between the blood vessels in it, and with its outer environment. There are also mucus glands in the skin, these keep the skin moist. Their skin absorbs a lot of dissolved oxygen from the surrounding atmosphere.

In what year was the "@" chosen for its use in e-mail addresses?

Asked by Aryan Gusain in Computers & Technology at 12:59 PM on July 01, 2008

rOllEr's Answer

Before 1971, mail could only be sent to those who share the same computer. Raymond Samuel Tomlinson, a programmer who worked for Bolt Bernek and Newman, has invented a system which can send mail between users on different hosts connected to the ARPAnet. For this he used the ‘’@’’ sign to achieve this separation from the host and receiving machines for the first time in 1971. He thought of separating the two machines by a character which doesn’t occur often in both of their names. He came out with this symbol “’@’’ randomly.

'.JPG' extension refers usually to what kind of file?

Asked by Aryan Gusain in Computers & Technology at 1:00 PM on July 01, 2008

rOllEr's Answer

Actually .JPG file extension is a type of image file format. Full form of JPG is Joint Photographic Experts Group. It is an excellent compressed format of an image which maintains high quality after compressing graphics efficiently. It discards unnecessary data in the image.
JPG image since it is compressed loses some of the data and is no longer identical to the original. It is a compressed image which cannot be edited from its route because all its image content like layers, colors are lost to some extent. But it is the best and most seen format for web as it maintains good quality despite of low size.
