Hello dear friends!

Explain something about 32 bit OS and 64 bit OS as we hear lots of these in our daily life just like vista is 64 bit software and like that, what is the difference there and we need special hardware for these OS.

Also tell me What is the difference between BOURNE SHELL and DOS?

Hi dear its me M. Smith and I am a matter of Computer Sciences also a Developer etc.

 So, do not worry dear its so easy question and its my wish to help you.

Now listen there is no similarity or difference between these. These are all independent classical problems  to solve the critical sections. Actually when we have to test an algorithm related to critical section then firstly we test that algorithm on these classical problems.

The answer of second part of your question is  that In Batch system, a single job is executed at a time. These systems can not interact with the user while performing a particular task. Multi-programmed systems are those which can perform multiple programs simultaneously.

They are usually interactive and time sharing system.

Ok dear bye .

Hi good morning the term 32-bit and 64-bit refers to the way a computer’s processor (also called a CPU) handle information. The 64-bit version of windows handles large amounts of random access memory (RAM) more effectively than 32-bit system.

Example of the Spec of special hardware:

  • AMD PHENOM II X2 555 3.2 GHz
  • Asrock N68-S3 UCC
  • 2 GB DDR3
  • 500 GB SATAII
  • Palit NVIDIA Geforce 8400 GS 512 MB DDR2
  • Samsung DVDRW 22x22x with trueDirect Technology
  • 500 Watts PSU
  • High quality Powerlogic V17 case.

2. Command execution program, often called a command interpreter, the Bourne shell is also known by its program name, sh. The shell prompt character displayed to indicate readiness for input, The acronym of DOS (disk operating system) the term DOS can refer to any operating system, but it is most often used as a shorthand for MS-DOS (Microsoft disk operating system).

Thank you.
