Human-computer interaction Human–computer interaction (HCI) is the study of interaction between people (users) and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study. Interaction between users and computers occurs at the user interface (or simply interface), which includes both software and hardware, for example, general-purpose computer peripherals and large-scale mechanical systems, such as aircraft and power plants.

Compare the difference between pervasive computing and other computings?
First, let's look at what they mean. Ubiquitous means everywhere. Pervasive means "diffused throughout every part of." In computing terms, those seem like somewhat similar concepts. Ubiquitous computing would be everywhere, and pervasive computing would be in all parts of your life. That might mean the difference between seeing kiosks on every street corner and finding that you could -- or need to -- use your Palm handheld to do absolutely every information-based task. And, in fact, that's where the difference between these two types of computing lies. Pervasive computing involves devices like handhelds -- small, easy-to-use devices -- through which we'll be able to get information on anything and everything. That's the sort of thing that Web-enabled cell phones promise. Ubiquitous computing, though, eschews our having to use computers at all. Instead, it's computing in the background, with technology embedded in the things we already use. That might be a car navigation system that, by accessing satellite pictures, alerts us to a traffic jam ahead, or an oven that shuts off when our food is cooked. Where IBM is a leader in the pervasive computing universe -- it has a whole division, aptly called the Pervasive Computing division, devoted to it -- Xerox started the ubiquitous thing back in 1988. Ubiquitous computing "helped kick off the recent boom in mobile computing research," notes its inventor, Mark Weiser, who came out with the concept at Xerox's Palo Alto Research Center, "although it is not the same thing as mobile computing, nor a superset nor a subset." That means that people who use ubiquitous computing to mean computing anytime, anyplace -- to describe hordes on a street corner checking their stock prices until the "walk" light comes on or efforts to dole out laptops to all students on a college campus -- aren't using the rightterm. We don't really need to use either one. I'd be happy to call pervasive computing mobile computing, and to call ubiquitous computing embedded or invisible or transparent computing -- or even just built-in functions. Besides, until either ubiquitous or pervasive computing is anywhere and everywhere, those alternatives seem more accurate.

What is nested tables?
In computing, nested refers to something inside another thing. Nested tables is having tables inside other tables. There are situations where this is useful. For example, normally you cannot have two tables beside each other in HTML. One way of doing that is to create one large table with a single row and two cells. Into each of the two cells you would put one table. The two tables will be sitting beside each other and they are nested insided the outer table. You could hide all borders on the outer table, further emphaisising the way the two tables are sitting beside each other. In furniture, it is a collection or set of tables that stack together.

What is the difference between patvasive and ubiquitous computing?
I just found out that ubiquitous computing and pervasive computing aren't the same thing. "What?!?" you're saying. "I'm shocked." Yes, brace yourselves. This time it appears to be the scientists, not the marketers, who adopted everyday terms to describe their once-futuristic technology, making things very confusing now that other folks are using those ordinary words -- sometimes interchangeably -- without their particular nuances in mind. Now, I'm not going to blame anybody here -- they're a lot smarter than I am, and they started their research a long time ago -- but I'm going to suggest that things have come far enough that there are easier ways to explain what is meant by these terms. First, let's look at what they mean. Ubiquitous means everywhere. Pervasive means "diffused throughout every part of." In computing terms, those seem like somewhat similar concepts.

When would one use utility system software?
There are two possibilities, utility as in software that helps in working with a system or utility computing. Utility computing is a way of making computing power available to users as though it is electrical power. Think of SETI (Search for Extraterrestrial Intelligence) as an example of such utility computing. Using the former definition, one could use utility system software for an easy interface to a computer. In the later definition, there are numerous emerging examples in 'cloud' computing, SETI is just one example.
Is there a website that compares cloud computing vs. Saas?
No, there is not a website that compares the two, but they are similar. Cloud computing just has more new features.
What are the differences between the two?
The advantages and disadvantages between the two are quite simple. SOA cloud computing is the term used to tell the idea of computing clouds and the electronics used are to help figure it out.
What are the main types of MPUs?
The two major types of MPUs are CISCs (complex instruction set computing) and RISCs (reduced instruction set computing).
What two colleges host the sites for the NSF computing sites in 1997?
boo
Is there a site that summarizes the details of cloud computing?
There are many sites that summarize cloud computing. Two of the best sites that I know of are Microsoft and Hewlett Packard. I hope that this helps you.
What are the differences between parallel system and distributed system?
What is the difference between parallel computing and distributing computing? In the most simple form = Parallel Computing is a method where several individual (autonomous) systems (CPU's) work in tandem to resolve a common computing workload. Distributed Computing is where several dis-associated systems are working seperatly to resolve a multi-faceted computing workload. An example of Parallel computing would be two servers that share the workload of routing mail, managing connections to an accounting system or database, solving a mathematical problem, ect... Distributed Computing would be more like the SETI Program, where each client works a seperate "chunk" of information, and returns the completed package to a centralized resource that's responsible for managing the overall workload. If you think of ten men pulling on a rope to lift a load, that is parallel computing. If ten men have ten ropes and are lifting ten different loads from one place to consolidate at another place, that would be distributed computing.

How soft computing differ from hard computing?
1) Hard computing, i.e., conventional computing, requires a precisely stated analytical model and often a lot of computation time. Soft computingdiffers from conventional (hard) computing in that, unlike hard computing, it is tolerant of imprecision, uncertainty, partial truth, and approximation. In effect, the role model for soft computing is the human mind.2) Hard computing based on binary logic, crisp systems, numerical analysis and crisp software but soft computingbased on fuzzy logic, neural nets and probabilistic reasoning.3) Hard computing has the characteristics of precision and categoricity and the soft computing, approximation and dispositionality. Although in hard computing, imprecision and uncertainty are undesirable properties, in soft computing the tolerance for imprecision and uncertainty is exploited to achieve tractability, lower cost, high Machine Intelligence Quotient (MIQ) and economy of communication4) Hard computing requires programs to be written; soft computing can evolve its own programs5) Hard computing uses two-valued logic; soft computing can use multivalued or fuzzy logic6) Hard computing is deterministic; soft computingincorporates stochasticity7) Hard computing requires exact input data; soft computing can deal with ambiguous and noisy data8) Hard computing is strictly sequential; soft computing allows parallel computations9) Hard computing produces precise answers; soft computing can yield approximate answers
Where can I find information on how cloud computing works?
Cloud computing is something that has two different meanings. It usually is referring to an online storage, like Cloud Net, where you can store things from your IPod.
