A class is an approach to bind the data, describing the entity or an object, and its associated functions together. In C++, a class creates a data-type that is used to create objects of that particular type. Class represents a group of similar objects. Example: class account { private: int accoutno; char type; float balance; public: float deposite(float amount) { balance += amount; return balance; } float withdraw(float amount) { balance -= amount; return balance; } }; In the above example, the data describing an account object (i.e. accountno, type Read More

A field-effect transistor (FET) is a semi-conductive device that is used in integrated circuits to control the conductivity of a conductive channel. FETs are highly dependent on negative and positive charges. They have many purposes, including limiting a device’s power levels, storing data, and being used as a switch for a wide variety of electronic devices. Various FET designs have been presented and produced since 1925 and have collectively allowed modern electronics to be possible. How Field-Effect Transistors Work FETs are dependent on four essential components: the base, the source, Read More

Simplex locks, now manufactured by Kaba Ilco, are simple push-button combination locks. Simplex locks are used to protect equipment rooms, labs, and FedEx-type boxes. Simplex locks are used whenever having a large number of keys would create logistical problems. Simplex Lock Combinations The Simplex lock would be a normal 5-button combination lock, except for one weakness. Each button on a Simplex lock may only be used once in a combination. A combination of 1-4-3-2 is acceptable. A combination of 1-4-3-1 will not work. This limits the Simplex lock to only Read More

WINS Server Role Security Issues A WINS server is an enhanced NetBIOS name server that can resolve NetBIOS computer names to IP addresses. The WINS database hosted on the WINS server is used to store and maintain NetBIOS computer names to IP addresses mappings. WINS registers NetBIOS computer names, and then stores these client name registrations in the WINS database. A WINS server is basically needed if there are applications that require WINS for name resolution to operate correctly. WINS is also typically needed if all your domains have not Read More

Ozone or O3, is a molecule similar to oxygen that is made up of three oxygen atoms. While ozone in the lower atmosphere is harmful to humans, plants, and animals, causing respiratory problems in humans and animals while burning some types of plants, ozone in the upper atmosphere, known as the “ozone layer”, is highly effective at preventing harmful electromagnetic radiation from the Sun and other stars from reaching the Earth. By doing this, ozone is responsible for limiting the effects of global warming. While ozone in the lower atmosphere Read More

Cloaking is a black hat SEO technique where one set of content is shown to human visitors and another set of content is shown to search engines. In cloaking, human visitors are shown the actual web page, but search engines are shown a web page which is full of spammy SEP techniques such as keyword stuffing. Cloaking by User Agent To effectively cloak a web page, the web server must be able to determine if the visitor is a human or a search engine. One technique for doing this is Read More

Error 0x0000007e is an error message that is displayed whenever a computer cannot access one of its hard drives, ports, optical drives, system files, or other critical components necessary to run the operating system. Usually, the computer’s error handler discovers these problems immediately upon booting from a device and will display a specific error message before the user is able to log in. However, if an exception occurs that prevents the error handler from discovering these problems immediately, it will display Error 0x0000007e after the computer has booted up and Read More
