Operating Systems

Light weight is called as a thread which runs inside a process and a heavy weight is a system process.

As the thread share the memory of heavy weight then we can say that it is not taking any additional resources(memory) to execute.

As a process is a combination of one of more then one threads and each process is having the separate memory location so it is very easy for thread to communicate with each other as compare to two process communicate because thread communicate within same memory but process communicate with other process having different memory location.

Here we can consider light weight as a thread and heavy weight as a process.

1. It is a Primitive Operating System.

2. Usually in low memory where interrupt vectors are placed.

3. It Isolate user from physical address space using logical address space

QNX is free for personal use. Commercial licenses vary in price for runtime (installed) copies.

The types of geomorphic systems are open and closed geomorphic systems.

True!

Yes

# Open Active Directory Sites and Services. # Expand the site name in which the standby operations master is located to display the Servers folder. # Expand the Serversfolder to see a list of the servers in that site. # Expand the name of the server that you want to be the standby operations master to display its NTDS Settings. # Right-click NTDS Settings, click New, and then click Connection. # In the Find Domain Controllers dialog box, select the name of the current role holder, and then click OK. # In the New Object-Connection dialog box, enter an appropriate name for the Connection object or accept the default name, and click OK.

Absolutely. Just because the OS is generally real time and kernel priority doesn't mean that a user process can't use a semaphore. After all there are real time user processes and they need to signal or block each other. And user processes can get into a deadly embrace situation as well; it doesn't mean the computer is down, but the user processes are stuck and will have to be killed in order to get out of the deadly embrace.

Dual-boot means that you use two operating systems on one computer. Multiboot refers both to having several operating systems (usually more than three) on a computer, and to an operating system having built-in support for a bootloader that can load multiple operating systems (Linux, FreeBSD, and Solaris are all multiboot compliant, since they can accept kernel parameters directly from GRUB).

An operating system is the system working on the computer. Linux and Windows are both operating systems used in businesses.

The program could maximize the CPU time allocated to it by not fully utilizing its time quantums. It could use a large fraction of its assigned quantum, but relinquish the CPU before the end of the quantum, thereby increasing the priority associated with the process.
