What are the differences between private cloud and public cloud ? Please define both and giving examples with usage. A public cloud is offered as a service via web applications/web services( usually over an Internet connection). Private cloud and internal cloud are deployed inside the firewall and managed by the user organization. There is another type of cloud, hybrid cloud. A hybrid cloud environment consisting of multiple internal and/or external providers will be typical for most enterprises. You will get more understanding here . The same as the difference between an intranet and the

I was trying to understand what object decomposition means and read a lot of stuff on internet but every resource talks in terms of lots of keywords that i couldn't understand. So these resources expect you to know a few terms. I need something that lists the basics of decomposition from scratch. Is it anything more than breaking the design into objects? If no, any description will be appreciated. Thanks in advance Imagine, you have Car object. It is very large object, hard to support. You break this objects into smaller responsible for some part of the problem domain: Engine Сabin Boot ...

Consider: p { ... } .foo { ... } #bar { ... } What is the correct name for these statements in CSS? I've seen them called selectors, rules or rulesets, but which is correct? JoshBerke A rule would be considered: p {…} A selector in this case is: p A rule is made up of selectors and declarations. A declaration is property:value so the entire rule would be: selector { property:value } A rule can have multiple declarations and multiple selectors so we can actually have: selector, selector2 { property:value; property2:value; } A rule set would be multiple rules. Here's a quick source on this or

What are futures? It's something to do with lazy evaluation. Motti There is a Wikipedia article about futures. In short, it's a way to use a value that is not yet known. The value can then be calculated on demand (lazy evaluation) and, optionally, concurrently with the main calculation. C++ example follows. Say you want to calculate the sum of two numbers. You can either have the typical eager implementation: int add(int i, int j) { return i + j; } // first calculate both Nth_prime results then pass them to add int sum = add(Nth_prime(4), Nth_prime(2)); or you can use the futures way using C+

I've seen it in the context of classes. I suspect it means that the class could use being broken down into logical subunits, but I can't find a good definition. Could you give some examples? Thanks for the help. Edit: I love the smart replies, but I'm obviously referring to "monolithic" within a software context. I know about monoliths, megaliths, dolmens, and all the stone-related contexts. Gee, I have enough of them in my country... Interesting question. I don't think there are any formal definitions of what a monolithic class is, but you've got the idea. A class that contains multiple
