assigned by the Company!!!and every mac id is unique...
but to see ur existing mac id we use "ifconfig" in UNIX

Error
An array of string cannot be directly assigned to other;
soln: char *str1="prakash"

(3)shared memory segments
reason:-When a fork() system call is issued, a copy of all
the pages corresponding to the parent process is created,

One can not compare the performence for a sheduling 
algorithm. as they depends on the use or the requirements 
of the system.
for example for one case the FCFC algo can be better and 
for the other case the SJF can be benificial.

We can compare the scheduling algorithm by using the 
following methods.
1. throughput
2. turn aroung time
3. waiting time
4. response time

A collision domain is a logical area in a computer network 
where data packets can "collide" with one another, in 
particular in the Ethernet networking protocol. The more 
collisions in a network the less efficient it is. 


A broadcast domain is a logical area in a computer network 
where any computer connected to the computer network can 
directly transmit to any other in the domain without having 
to go through a routing device.

Yes you are right. Using machine language we can run program
without OS.

yes, we can

yes, if we provide memory management,cpu management and i/o
management in machine language(or implemented @ hardware
level), we can execute any program without os

no, we can't exucute any program w/o os.bcoz it controls 
all the operations of the computer

yes we can, bcz in the early systems that were without 
operating systems, we were in a position to execute the 
user porgrams (before 1956 when first os was developed)

ya,through processor only we can. 
If we know the clear definition of the Os then its become
simple.
