Computer Hardware:

What is Computer Hardware?

Hardware, in the computer world, refers to the physical components that make up a computer system.
There are many different kinds of hardware that can be installed inside, and connected to the outside, of a computer.
In information technology, hardware is the physical aspect of computers, telecommunications, and other devices. The term arose as a way to distinguish the "box" and the electronic circuitry and components of a computer from the program you put in it to make it do things.
A computer system consists of two major elements: hardware and software. Computer hardware is the collection of all the parts you can physically touch. Computer software, on the other hand, is not something you can touch. Software is a set of instructions for a computer to perform specific operations. You need both hardware and software for a computer system to work.

Some hardware components are easy to recognize, such as the computer case, keyboard, and monitor. However, there are many different types of hardware components. In this lesson, you will learn how to recognize the different components and what they do.

Types of Computers
Before looking at the various components, it is useful to distinguish between two different types of computers: desktop computers and laptop computers. A desktop computer consists of a computer case and a separate monitor, keyboard, and mouse. As the name suggests, this type of computer is typically placed on a desk and is not very portable.

A laptop computer has the same components but integrated into a single, portable unit.

While these two types of computers look quite different, they have the same general hardware components.

hackers

hacker

Hacker is a term used by some to mean "a clever programmer" and by others, especially those in popular media, to mean "someone who tries to break into computer systems.

What Is a Hacker?


The Jargon File contains a bunch of definitions of the term ‘hacker’, most having to do with technical adeptness and a delight in solving problems and overcoming limits. If you want to know how to become a hacker, though, only two are really relevant.

There is a community, a shared culture, of expert programmers and networking wizards that traces its history back through decades to the first time-sharing minicomputers and the earliest experiments. The members of this culture originated the term ‘hacker’. Hackers built the Internet. Hackers made the Unix operating system what it is today. Hackers make the World Wide Web work. If you are part of this culture, if you have contributed to it and other people in it know who you are and call you a hacker, you're a hacker.

The hacker mind-set is not confined to this software-hacker culture. There are people who apply the hacker attitude to other things, like electronics or music  actually, you can find it at the highest levels of any science or art. Software hackers recognize these kindred spirits elsewhere and may call them ‘hackers’ too and some claim that the hacker nature is really independent of the particular medium the hacker works in. But in the rest of this document we will focus on the skills and attitudes of software hackers, and the traditions of the shared culture that originated the term ‘hacker’.

There is another group of people who loudly call themselves hackers, but aren't. These are people (mainly adolescent males) who get a kick out of breaking into computers and phreaking the phone system. Real hackers call these people ‘crackers’ and want nothing to do with them. Real hackers mostly think crackers are lazy, irresponsible, and not very bright, and object that being able to break security doesn't make you a hacker any more than being able to cars makes you an automotive engineer. Unfortunately, many journalists and writers have been fooled into using the word ‘hacker’ to describe crackers; this irritates real hackers no end.

 google programming language:-

Google's Go: A New Programming Language That's Python Meets C++". TechCrunch. Retrieved 18 January 2010

C++ generally powers compute-intensive back-end services, Java (and a wealth of libraries including  , and Guava) is often used for application logic, and many scripts are written in Python. Parts of YouTube are written in Python as well as some App Engine applications.

JavaScript is heavily used for client-side code, sometimes translated from Java with GWT (formerly Google Web Toolkit), and other times written by hand with the suite of Closure tools. Closure templates are written in a simple language called Soy.


Big news for developers out there: Google has just announced the release of a new, open sourced programming language called Go. The company says that Go is experimental, and that it combines the performance and security benefits associated with using a compiled language like C++ with the speed of a dynamic language like Python. Go’s official mascot is Gordon the gopher, seen here.

Today we're releasing Hack, a programming language we developed for HHVM that  seamlessly with PHP. Hack reconciles the fast development cycle of PHP with the discipline provided by static typing, while adding many features commonly found in other modern programming languages.

We have deployed Hack at Facebook and it has been a great success. Over the last year, we have migrated nearly our entire to Hack, thanks to both organic adoption and a number of homegrown refactoring tools.

Working alongside a handful of others inside the social networking giant, they fashioned a language that lets programmers build complex websites and other software at great speed while still ensuring that their software code is precisely organized and relatively free of flaws — a combination that few of today’s languages even approach. In typical Facebook fashion, the new language is called Hack, and it already drives almost all of the company’s website — a site that serves more than 1.2 billion people across the globe.

“We can say with complete assurance that this has been as battle-tested as it can possibly be,” says , a veteran of iconic tech companies Sun and Linden Lab who has long played an important role in a popular language called Haskell.
and company publicly revealed their new language this morning, and at the same time, they “open sourced” it, sharing the technology with the world at large and encouraging others not only to use it, but to help improve it.

The software world is littered with programming languages, and new ones appear all the time. But according to some who have used it or who know the past work of those who built it, Hack has a design and a pedigree that immediately set it apart.

html5 C++

Is it possible to develop a C++ program while using HTML and CSS for the user interface? I know about programming with Javascript using a container, but I am really interested in C++ development.

I felt in love with C# when I developed under Windows, but now I moved to Linux and I haven't found a good tool for using markup for interfaces. For this, I would like to mix HTML and CSS, which are very lightweight and easy to use, with C++ code, with something like WPF.

Oh, one more thing: I'm looking for desktop development, not web.

c++ user-interface desktop-application

This overview of the Wormhole JavaScript Library gives you access from an HTML5 application to native user interface components as well as cameras, compasses, files storage, push notifications, sensors, and a whole lot more.

In physics, a wormhole is a shortcut through . In the universe, a wormhole connects JavaScript and C/C++.  The Wormhole Library consists of two parts, at one end is the JavaScript API, and at the other end is a C/C++ API.

With the Wormhole C++ Library you can easily add your own C/C++ code and invoke it from JavaScript, using the same JavaScript to C/C++ bridge as the Wormhole library uses. The bridge is fully available to every MoSync application and lets to both invoke C/C++ code and call back into JavaScript again.
supports the standard smartphone implementations of HTML5. That means it is possible to create rich web applications using JavaScript and CSS over the powerful core. You can even mix HTML5 UI components and Native UI widgets.

You can edit HTML and JavaScript files directly in the MoSync IDE with syntax support. There are easy-to-use project templates to get you started. The helps you to develop and test your code on the emulators for Android, iOS and Windows Phone. And the lets you quickly create a ready-to-install package for your app, that can be published on the App Stores.

If you are a C++ developer, you can benefit from creating cool looking user interfaces in HTML and CSS. And you don't need to master all the dirty details of CCS, as you can choose from a rich selection of high-level JavaScript libraries available on the Internet, like , Mobile, and Touch.

computer programmer

Computer programmers use their skills to write code and create software programs that tell computers to accomplish certain tasks like retrieving data. They may also rewrite, debug, maintain and test these programs. Computer programmers use specific codes or computer languages, like Java and C++, to transform the program designs created by software developers and engineers into instructions that the computer can follow. They often reference code libraries to simplify their writing, and may build or use computer-assisted software engineering tools to automate the writing of some of the codes they use. - See more at.

If you want to become a computer programmer, it's a good idea to earn an IT degree. While most employers require a bachelor's degree, some will hire experienced individuals with an associate's degree or certificate. If you plan on applying your programming skills to a specific field, such as health care, it's a good idea to take some classes that will expand your knowledge of that industry. While you are not required to be certified to become a computer programmer, earning certifications for specific programming languages may be helpful.

computer software engineering

computer software engineering

A software engineer is a licensed professional engineer who is schooled and skilled in the application of engineering discipline to the creation of software. A software engineer is often confused with a programmer, but the two are vastly different disciplines. While a programmer creates the codes that make a program run, a software engineer creates the designs the programmer implements. By U.S. law no person may use the title "engineer" (of any type) unless the person holds a professional engineering license from a state licensing board and are in good standing. A software engineer is also held accountable to a specific code of ethics.

1.Development of procedures and systematic applications that are used on electronic machines. Software engineering incorporates various accepted methodologies to design software. This particular type of engineering has to take into consideration what type of machine the software will be used on, how the software will work with the machine, and what elements need to be put in place to ensure reliability.
2.Higher education degree program, which usually requires a certain number of courses to be completed in order to receive certification or a degree.

The application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software, and the study of these approaches. That is the application of engineering to software.

computer hardware engineering

computer hardware engineering

Computer hardware engineers analyze complex equipment to determine the best way to improve it. They design new types of information technology devices. They use logic and reasoning to clarify goals, examine assumptions, and identify the strengths and weaknesses of alternative solutions to problems. They identify complex problems in computer hardware, develop and evaluate possible solutions, and figure out the best way to implement them. Engineers often work on teams and must be able to communicate with other types of engineers as well as with non-technical team members.

Computer hardware engineers ensure that computer hardware components work together with the latest software developments. Therefore, they sometimes work with software developers. For example, computer hardware engineers give developers of mobile applications information about what kind of software a cell phone can run.

Definition - What does Computer Engineering mean?

Computer engineering refers to the study that integrates electronic engineering with computer sciences to design and develop computer systems and other technological devices. Computer engineering professionals have expertise in a variety of diverse areas such as software design, electronic engineering and integrating software and hardware.

Computer engineering allows professionals to engage in a number of areas such as analyzing and designing anything from simple microprocessors to highly featured circuits, software design, and operating system development. Computer engineering is not limited to operating computer systems but is aimed at creating a broad way to design more comprehensive technological solutions.

Also known as computer system engineering.explains Computer Engineering

The term computer engineering is often confused with computer science, but these two terms are different. Computer scientists are responsible for electrical and software manufacturing, while computer engineers are trained to design software and perform and integrate that software with hardware components. Computer engineering also includes the engineers who write firmware specifically for embedded , design and develop analog sensors, design very-large-scale integration chips, and create schemes for mixed- and single-circuit boards. The engineering field of computer sciences also contributes to robotic research that requires digital systems to monitor electrical components like motors and sensors.

A computer engineer, also called a software engineer, is responsible for developing, testing and evaluating the software that make our computers work. They may help in the development of new computer games, business applications or even in the design of entirely new operating systems. A computer engineer may also be responsible for constructing and managing an organization's computer system and supplying technical support. A computer engineer typically works in an office or laboratory environment as part of a team and enjoys a traditional work schedule.

How to Become a Computer Engineer
Education Required

The U.S. Bureau of Labor Statistics  reports that those working in computer engineering held a bachelor's degree or higher. Bachelor's degrees in software engineering or computer science are a common place to start. Coursework to prepare the student computer engineer will include such topics as database design, systems analysis, critical thinking and technical writing. Because computer technology is a field that is constantly changing, continued education is vital to a successful career in computer engineering.

Skills Required

People who enjoy a career in computer engineering usually have strong analytical skills and are able to focus on many tasks at once. Because computer engineers must sometimes work with customers and clients, the ability to express computer-related information in layman's terms is also valued.
