When using exec() the created process is a subthread of the calling process. They also share an area in the memory and therefore also all permissions and resources.
When you use fork() the newly created process is a complete independent process that has it's own area in memory and also uses it's own permissions depending on what you give it.
Hope this helps clear up things.
what is the difference between license and patent

Look up information on programming.
Multi-tasking is supported by the fork and exec subroutines in the C library.
Well, the major difference between Backup Exec and Netbackup is: 1. Backup exec basically is designed for Windows platform while Netbackup is designed for aan enterprise environment where multi-platform exist. Backup exec can also support other platforms but as a client server only. Media Server of Backup Exec should only reside/installed into a Windows Server. While Netbackup, the media and master server can be installed both on windows and non-windows server. 2. Backup exec has Continous Protection server feature while Netbackup has none. Also, I just want to add, the backup images from Backup Exec can be imported and restored using Netbackup. Hope this answer your inquiry. Mohamed El-Tayeb
exec: Program file does not exist; file exists, but does represent a valid executable file (e.g., it is a spreadsheet); file exists, but the user does not have permission to execute it (e.g., the file does not have the exec bit set, or the user does not have permission to access the file unlink: File does not exist; user does not have permission to access the file. fork: No more processes (OS out of memory).
The difference between 98 expeditions and the Eddie Bauer edition are a few things for example Digital Thermostat, rear vent windows, air suspension, exec...
Means that the difference in length between fully extended and fully compressed fork is 100 mm (4").
In Unix systems, a fork system call followed by an exec systemcall need to be performed to start a new process. The fork call clones thecurrently executing process, while the exec call overlays a new processbased on a different executable over the calling process.
The exec family of UNIX system calls will overlay the current process with another process. It can be used to "chain" a series of programs to run together. When used with the "fork" system call it allows multi-tasking to occur.
