How many devices can a PC using an internal USB 2.0 interface support?

If you have 2.0 hubs and 2.0 hardware, then yes, they should work. You can use 1.1 hardware in a 2.0 hub. It's just slow, that's all.

What are the advantages of using the same system-call interface for manipulating both files and devices?
Each device can be accessed as though it was a file in the file system. Since most of the kernel deals with devices through this file interface, it is relatively easy to add a new device driver by implementing the hardware-specific code to support this abstract file interface. Therefore, this benefits the development of both user program code, which can bewritten to access devices and files in the samemanner, and device driver code, which can be written to support a well-defined API. The disadvantage with using the same interface is that it might be difficult to capture the functionality of certain devices within the context of the file access API, thereby either resulting in a loss of functionality or a loss of performance. Some of this could be overcome by the use of ioctl operation that provides a general purpose interface for processes to invoke operations on devices.

Can you hook Bare Hard Drive to a Win 7 computer using USB port?
If you're talking about using a internal hard drive with USB interface, yes. You need a IDE or SATA to USB interface cable that is available in many computer stores.

How many scsi devices can be attached to a wide scsi host adapter?

Is ther some inbuilt facility in 8051 microcontroller to interface it with other peripheral devices or peripheral interface like 8255 should be used along with it?
The 8051 can directly interface with a number of I/O. The 8255 just gives you the abilty to access 3 eight bit ports using a minimum number of control bits from the 8051
How is the using pattern useful What is IDisposable How does it support deterministic finalization?
The using statement defines a scope at the end of which an object will be disposed. You create an instance in a using statement to ensure that Dispose is called on the object when the using statement is exited. A using statement can be exited either when the end of the using statement is reached or if, for example, an exception is thrown and control leaves the statement block before the end of the statement. The object you instantiate must implement the System.IDisposable interface. IDisposable is a very special interface. It is meant to be used with the "using" key word so it is very different than most any other interface as it has compile time support. It is meant for _exception safe_ deterministic cleanup of resources.

You would probably need to get drivers for the drive somewhere on the internet to make it work.

How does one go about using a java 7 socket?
A socket is used in computer programming and helps two devices to make a connection. In Java 7, sockets can be employed utilizing the TCP/IP interface.
Is interface class a valid term?
Yes. An interface in essence is a java class and so you can use the term interface class. But, using the term class along with the term interface can cause ambiguity or misunderstandings among novice java developers. So, using the term "Interface" along would suffice to refer to a type of class which is the "Interface"
