NWLink is used in Novell NetWare, and can be considered IPX for Windows. NWLink is an IPX/SPX compatible transport protocol that was developed to enable Windows 2000 computers to communicate with NetWare services. It is therefore used when clients running Microsoft operating systems (OSs) need to access resources on NetWare servers. It is also used where clients running NetWare need to access resources on computers running Read More

A projector lamp is used to transfer an image from a multimedia projector onto a larger screen. Earlier halogen bulbs were used for many years for projection purposes, but were discontinued as halogen produced a yellow tone on the images. A projector lamp relies on an intense light bulb, called a metal halide bulb, to produce a brilliant white light. The light bulb shines onto a number of small mirrors inside the machine and transfers the image through the air and onto the screen. These machines can project slides, films, Read More

Understanding the Limitations of IPv4 Before moving on the to an in-depth discussion of IPv6, lets first look at the limitations of IPv4: The IPv4 addresses are somewhat scarce, even though it allows for 4,294,967,296 possible addresses. Because of this limitation, organizations are forced to utilize Network Address Translator (NAT) to map a public IP address to several private IP addresses. NAT typically creates performance and application bottlenecks. The increase in devices that are connected to the Internet would lead to the depletion of IPv4 address space. There is a Read More

A MySQL password can be reset in 5 easy steps: Stop the mysqld daemon process. Start the mysqld daemon process with the –skip-grant-tables option. Start the mysql client with the -u root option. Execute the UPDATE mysql.user SET Password=PASSWORD(‘password’) WHERE User=’root’; Execute the FLUSH PRIVILEGES; command. These steps reset the password for the “root” account to “password.” To change the password for a different account or to set a different password, just edit the variables in single quotes in step 4.

Function overloading is a concept where several function declarations are specified with a single and a same function name within the same scope. Such functions are said to be overloaded. C++ allows functions to have the same name. Such functions can only be distinguished by their number and type of arguments. Example: float divide(int a, int b) ; float divide(float a, float b) ; The function divide(), which takes two integer inputs, is different from the function divide() which takes two float inputs. What is the need for function overloading? Read More

Jets are able to move much faster than other types of aircraft and they especially move faster than regular forms of transportation such as trains and automobiles. In exchange for all the extra speed, however, jet engines must be designed and built differently than normal engines. This article will explain what jet engines do that are so special and list a number of parts that are crucial to the jet engine's ability to generate such high speeds. What Do Jet Engines Do Jet engines, also known as gas turbine engines, Read More

A metal detector uses an electromagnetic field to detect the presence of a concealed metal object. The range depends on the strength of the field, and is usually less than one meter from the search head. The three detection methods are beat frequency oscillation, very low frequency, and pulse induction. Metal detectors were first introduced around 1930 and are used in many different applications. How Metal Detectors Work The beat frequency oscillation method uses two coils connected to an oscillator. When the search head coil passes over a metal object, Read More
