The kernel in Unix-based operating systems like Linux is called the "Linux kernel." In Windows Vista, the kernel is known as the "Windows NT kernel." Each kernel serves as the core component of the operating system, managing system resources, providing essential services, and facilitating communication between software and hardware components.

What is Cygwin used for?

Cygwin is used to port applications that were written for Unix or Linux to a Windows environment.


What is the difference between C and Linux?

There is very little difference in the C compiler between Unix and Linux; in some cases (the gcc compiler) it is the same. The differences come in when using system calls; some system calls do not exist in Unix or Linux, although most do. The program I work on compiles the same way (for the most part) between all commercial versions of Unix and several variants of Linux. In other words, the code is fairly portable across platforms.


Why is Unix open source?

Unix is not open source, it is proprietary. Linux is the open-source version of Unix.


What are the advantages of Linux over Unix?

Unix is a classification of operating systems that conform to a certain specification, based on that of the original Unix operating system created by AT&T. Systems certified as Unix can differ drastically, but must meet at least certain common elements. Solaris is an implementation of Unix created by Sun Microsystems. Linux is a family of operating systems based on a kernel written by Linus Torvalds. It shares some design goals and similarities with Unix, but has several advanced features and is not completely compatible with Unix. Legally, for a system to be described as "Unix", it must undergo a certification process. No Linux distribution has ever undergone this (very expensive) certification process to make it compliant with Unix standards. Solaris uses older, POSIX-compliant utilities. Linux typically uses GNU utilities, which are generally compatible, but have different command switches and more features. This is beginning to change with the OpenSolaris project, which incorporates many GNU utilities. Solaris and Linux both have features that the other lacks, and are not found in other Unix implementations either. These include DTRace and the ZFS file system (in Solaris) and dynamically loadable kernel modules and epoll (in Linux).


How do you get the class file size in java?

You look at the file. A program such as Windows Explorer - or the equivalent in other operating systems - can tell you the size. Also, a command such as "dir" (in Windows), or "ls" (in Linux or Unix).
