Modal verbs in English.

What are modal verbs? 
Modal verbs are used to express certain hypothetical conditions, such as advice, capability, or requests (there’s a full list in the next section). They’re used alongside a main verb to change its meaning slightly. Because they’re auxiliary verbs, they can’t necessarily be used on their own. (A modal verb should only appear alone if it’s clear from context what the main verb is.) 
Consider the difference between these two examples: 
I swim every Tuesday. 
I can swim every Tuesday. 
The first example is a simple factual statement. The speaker participates in a swimming activity every week on Tuesdays. 
The second example uses the modal verb can. Notice how the meaning changes slightly. The speaker does not swim every Tuesday; they’re saying they are capable of swimming every Tuesday if they need to. It’s hypothetical. 
Modal verbs are quite common in English, and you’ve probably seen them hundreds of times without actually knowing their name. The most frequently used ones are: 

• 
  Can,may,might,could,should,would,will, must
  

There are more modal verbs, although the ones above are the most common. Some modal verbs are outdated and rarely used—like shall and ought to—while others are more colloquial—such as got to, need to, or have to. Some express very specific conditions that don’t come up often, like dare, for example, “I dare say.” The phrase used to, as in “I used to be an English student, too,” also behaves like a modal verb. 
When are modal verbs used? 
What special conditions do modal verbs show? Here’s a list of when to use modal verbs, along with examples: 
How to use modal verbs (with xamples)
Luckily, using modal verbs in a sentence is pretty simple. For basic sentences—the simple present tense—just remember these rules: 

• 
  Modal verbs always come directly before the main verb (except for questions).
  
• 
  With modal verbs, use the infinitive form of the main verb without “to”.
  

So, if you want to brag about your ability to eat an entire pizza, you take the infinitive form of “eat” without “to”—which is simply “eat”—and add the modal verb “can” in front of it. The rest of the sentence continues as normal. 
I can eat an entire pizza. 
For questions, you still use the infinitive form of the main verb, but the order is a little different: 
[modal verb] + [subject] + [main verb]
So let’s rephrase the example above as a question:
Can you eat an entire pizza? 

Multimedia hardware

Most of the computers now-a-days come equipped with the hardware components required to develop/view multimedia applications. Following are the various categories in which we can define the various types of hardwares required for multimedia applications.
ProcessorThe heart of any multimedia computer is its processor. Today Core 15 or higher processor is recommended for a multimedia computer.
CPU is considered as the brain of the computer.
CPU performs all types of data processing operations.
It stores data, intermediate result and instructions (program).
It controls the operations of all parts of computer.
