Business consultants are individuals or firms with expertise in business procedures, practices and policy. Organizations of all types use consultants, and these consultants examine these organizations from a broad operational perspective applying a variety of skills to achieve a specific outcome, solution, or result. Through analysis and study, consultants provide problem resolution and prevention solutions related to business operations, infrastructure, and performance. Consultants have many roles, varying from a supportive one within an existing team, to providing temporary leadership over an identified problem area, to other independent activities conducted at the request of the organization. This category has been divided into three areas to reflect the many functions and roles within the business consulting profession. The top level is divided by some of the various specialty or focus areas typical to the business consulting industry (e.g., business formation, financial, management, manufacturing, outsourcing, etc.). The second level contains a variety of industry specific subcategories (e.g., construction, energy, engineering, science and industry, security, etc.). Within the lowest level is a list of closely related "See also" categories that may contain other types of consultants. Before you submit your site please take the time to look around the category to ensure that your site is appropriate to this category. Also, be sure to review the general guidelines for the Business categories. The editors reserve the right not to list your site, and to delete it after its addition. Multiple submissions may be considered when appropriate (for example, a site that contains valuable resources pertinent to multiple subcategories) but repeated submissions, especially to inappropriate categories, will not be tolerated. Please, submit only to those categories most appropriate to the content of your site.

This is not a category in which to be included. If you have a site which has to do with the internet, please look below this category for the appropriate one. Submission Guidelines - The Open Directory Project editors are committed to building the most useful Directory on the Internet. We want to help your promotion efforts by listing your site in a timely manner. We want your website to be found easily. By choosing the most appropriate category, you assist us in both these efforts. Sites which are incomplete, having Under Construction notices, or which contain broken graphics or links have a poor chance of being listed. Please wait to submit your web site until it is complete. Please double-check the URL, and, if possible, include an e-mail address so we may contact you if we have questions.

The field of Home Automation is expanding rapidly as electronic technologies converge. The home network encompasses communications, entertainment, security, convenience and information systems. This category holds sites of broad scope on the topic.

Computer programming is the art of writing software, instructions for computers to follow. At the base level, as understood by the computer, these instructions are written in machine code, or binary, pure numbers, quite difficult for humans to read and write. At a slightly higher level, these codes correspond to assembly language, short mnemonics for individual computer operations, that still correspond one to one with what the machine actually does. This is still unstructured, terse, and difficult to read or write in. Most programming is done in higher level, compiled languages, or even interpretedthat look like a cross between English and Algebra, and allow various abstractions depending on the language, such as encapsulation, function calls, data hiding, and more, to enable people reading and writing programs to deal with the vast quantity of information that the computer actually handles. Respectively, a compiler program translates these languages to machine code to be executed directly, or a separate interpreter program itself takes these statements and executes them as an intermediary.

Robotics is a term coined by Isaac Asimov to describe the field of science involving robots and related technologies. So what is a robot? The word comes from a 1923 Czech play called R.U.R. and described autonomous, humanoid robot servants. The original Czech word was robota, which means "servitude or forced labor". According to the Syrius Cybernetics Corporation of Douglas Adams' Hitchiker's Guide to the Galaxy, a robot is "your plastic pal who's fun to be with". A more conventional definition is, "A mechanical device that sometimes resembles a human and is capable of performing a variety of often complex human tasks". There are many other definitions, some a bit too narrow and some far too broad. We try to be as inclusive as possible, accepting sites about hobby robotics, industrial robotics, even those about the radio-controlled entertainment vehicles of "Robot Wars". Enjoy our selections. And if you don't agree with some of our choices, rest easy in the knowledge that someone else out there wouldn't agree with yours.

Parallel computing is the science and art of programming computers that can do more than one operation at once, concurrently, during the same cycle, often via having more than one processor. Some parallel computers are just regular workstations that have more than one processor in them; others are giant single computers with many processors (these are generally referred to as supercomputers); and others are networks of individual computers. A network of computers configured to coordinate on computing problems is also called a cluster. Parallel computers can run some types of programs far faster than traditional single processor computers, often termed the von Neumann architecture. Programs that work on a single-processor computer don't automatically
