Traversing a list A linear list can be traversed in two ways In order traversal Reverse order traversal In order Traversal To traverse the linear linked list, we walk the list using the pointers, and process each element until we reach the last element. .cf { font-family: Lucida Console; font-size: 9pt; color: black; background: white; …
Wired Equivalent Privacy (WEP) is the encryption algorithm built into the 802.11 (Wi-Fi) standard. WEP encryption uses the RC4 stream cipher with 40 or 104 bit keys and a 24 bit initialization vector. WEP Key Generation Most 802.11 devices allow WEP keys to be entered using an ASCII passphrase or in hexidecimal format. The conversion …

Photoelectron spectroscopy is the study of energy and how it relates to matter in terms of absorption and production. Photoelectron spectroscopy observes both wavelengths and frequencies and is used to view the physical composition of chemicals and solids. It is used in both analytical and physical chemistry and astronomy in order to study an object’s …
In the age of HDTV, it is important to receive the best signals available to take advantage of the higher image quality that such display technology made possible. Pure Digital Television (PDTV) is the answer to this need. PDTV makes it possible to get direct feed from the video source and send it directly to …
What was once only a dream has now become a reality as space travel is a regular activity in our society. With thousands of satellites in orbit, the Hubble Space Telescope that can see other galaxies, regular shuttle launches, and prototypes for vehicles that can fly in and out of the atmosphere, it makes sense …
Low Earth Orbit (LEO) refers to a satellite which orbits the earth at altitudes between (very roughly) 200 miles and 930 miles. Low Earth Orbit satellites must travel very quickly to resist the pull of gravity — approximately 17,000 miles per hour. Because of this, Lowe Earth Orbit satellies can orbit the planet in as …
A DirecTV access card is a type of electronic card, roughly the size of a credit card, which provides programming to subscribers. DirecTV access cards may be provided to a customer along with his/her receiver box or separately, but must be activated before any programming can be used. When the user chooses a package and …
The conversion from basic to user defined data types can be done using constructors. Consider the following constructor: .cf { font-family: Lucida Console; font-size: 9pt; color: black; background: white; } .cl { margin: 0px; } .cb1 { color: green; } .cb2 { color: blue; } .cb3 { color: maroon; } String :: String(char *a) …
The Internet Assigned Numbers Authority (IANA) has allocated three IP address ranges that are to be exclusively used for private Internet networks: 10.0.0.0 – 10.255.255.255 (10/8 prefix) 172.16.0.0 – 172.31.255.255 (172.16/12 prefix) 192.168.0.0 – 192.168.255.255 (192.168/16 prefix) The first block “10.0.0.0 – 10.255.255.255” is referred to as the 24-bit block, the second “172.16.0.0 – 172.31.255.255” …
