C # is similar to Java in terms of syntax; it is an object-oriented language from Microsoft that started around 1997. C# also known as C sharp is available to run on multiple platforms, such as Windows, UNIX, Linux and Solaris. C# uses the Microsoft .NET framework and the Mono framework to be interpreted and translated into a language that is capable of running fast on any computer. C sharp is the third most popular language to be use with these frameworks and it is the most popular .NET language used today by .NET programmers. Anders Hejlsberg was the lead architect and principal designer of C#, he was involved with the design of Turbo Pascal, Embarcadero Delphi and Visual J++ before the creation of C sharp. The design of C# was driven by flaws in most major programming languages such as C++, Java, Delphi and Smalltalk, according to Anders Hejlsberg. C# however, was called an imitation of Java, by James Gosling, the creator of Java programming language and the co-founder of ...

 Java, having been developed in 1991, is a relatively new programming language.   At that time, James Gosling from Sun Micro systems and his team began designing the first version of Java aimed at programming home appliances which are controlled by a wide variety of computer processors.      Gosling's new language needed to be accessible by a variety of computer processors.  In 1994, he realized that such a language would be ideal for use with web browsers and Java's connection to the internet began.  In 1995, Netscape Incorporated released its latest version of the Netscape browser which was capable of running Java programs. Www.ITExpertTeam.Blogspo.Com Why is it called Java?  It is customary for the creator of a programming language to name the language anything he/she chooses.  The original name of this language was Oak, until it was discovered that a programming language already existed that was named Oak.  As t...

In the early 1970s, Dennis Ritchie of Bell Laboratories was engaged in a project to develop a new operating system.  Ritchie discovered that in order to accomplish his task he needed the use of a programming language that was concise and that produced compact and speedy programs. This need led Ritchie to develop the programming language called C. a      In the early 1980's, also at Bell Laboratories, another programming language was created which was based upon the C language.  This new language was developed by Bjarne Stroustrup and was called C++.  Stroustrup states that the purpose of C++ is to make writing good programs easier and more pleasant for the individual programmer.  When he designed C++, he added OOP (Object Oriented Programming) features to C without significantly changing the C component.  Thus C++ is a "relative" (called a superset) of C, meaning that any valid C program is also a valid C++ program.

Introduction Time and motion study (also referred to as motion and time study, the terms are used interchangeably) is the scientific study of the conservation of human resources in the search for the most efficient method of doing a task. A fascination with the word “efficiency” began in the late 19th and early 20th centuries when it was considered one of the most important concepts. Time study began in the 1880s as a means of wage-rate setting by Frederick W. Taylor, who is regarded as the “father of scientific management.” It consists of a wide variety of procedures for determining the amount of time required, under certain standard conditions of measurement, for tasks involving some human activity. Motion study was developed by Frank B. Gilbreth and Lillian M. Gilbreth and consists of a wide variety of procedures for the description, systematic analysis, and means of improving work methods. It is difficult to separate these two aspects completely. Therefore, the combined term ...

T he dictionary generally defines an electrician as a trades person who installs and maintains electrical systems in homes, businesses, and factories. At first glance, this might sound like a simple job, but you’ll find that it’s really quite complicated when you take a closer look. On most projects, the electrician is responsible for getting the electricity from the source to where it is needed in various parts of the building. To achieve this without endangering the public, he or she must have a good working knowledge of the relevant electric codes as well as the ability to translate the electrical systems from the blueprints into actual practice. Www.ITExpertTeam.Blogspo.Com Without electricians, there would be no lights, telephones, computers, or televisions plugged into our walls. Electricians also repair all electric machines and work in factories fixing motors, generators, and robots. Could you imagine what life would be like without electricians insuring we have all the...

Definition of electronics: Electronics is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons. This control of electrons is accomplished by devices that resist, carry, select, steer, switch, store, manipulate, and exploit the electron. Some of the basic electrical units and definitions are mentioned below: Passive: Capable of operating without an external power source. Typical passive components are resistors, capacitors, inductors and diodes (although the latter are a special case). Active: Requiring a source of power to operate.    Includes transistors (all types), integrated circuits (all types), TRIACs, SCRs, LEDs, etc. DC : Direct Current. The electrons flow in one direction only.  Current flow is from negative to positive, although it is often more convenient to think of it as from positive ...

I am regularly involved in troubleshooting problems with hydraulic equipment. In these situations, there are two steps I always complete before reaching for my test gear. The first is to conduct a visual inspection of the hydraulic system, checking all the obvious warning signs that could cause the problem in question (never overlook the obvious). The second is to ask for a circuit diagram for the hydraulic system. There are four types of hydraulic-circuit diagrams: block, cutaway, pictorial and graphical. Block Diagrams show the components of a circuit as blocks joined by lines, which indicate connections and/or interactions. Cutaway Diagrams show the internal construction of the components and flow paths. Because these diagrams typically use colours, shades or patterns in the lines and passages, they are very effective at illustrating different flow and pressure conditions. This makes them ideal for training purposes. Pictorial Diagrams show a circuit’s piping arrangeme...

Difference between CUI and GUI? • CUI and GUI are user interface used in connection with computers • CUI is the precursor of GUI and stands for character user interface where user has to type on keyboard to proceed. On the other hand GUI stands for Graphical User Interface which makes it possible to use a mouse instead of keyboard • GUI is much easier to navigate than CUI • There is only text in case of CUI whereas there are graphics and other visual clues in case of  GUI • Most modern computers use GUI and not CUI • DOS is an example of CUI whereas Windows is an example of GUI.

CNC  Introduction  Computer Numerical Control (CNC) machines are automated milling devices that make industrial components without direct human assistance. They use coded instructions that are sent to an internal computer, which allows factories to fabricate parts accurately and quickly. There are many different types of CNC machines, ranging from drills to plasma cutters, so they can be used to make a wide variety of parts. Though most are used industrially in manufacturing, there are also hobby versions of most of the machines that can be used in private homes. Types of Machines The most common CNC machines are milling machines, lathes, and grinders. Milling machines automatically cut materials, including metal, using a cutting spindle, which can move to different positions and depths as directed by the computer instructions. Lathes use automated tools that spin to shape material. They're commonly used to make very detailed cuts in symmetrical pieces, like cones an...
