Questions

Q:

Explain the popular multiprocessor thread-scheduling strategies.

Answer

  1. Load Sharing: Processes are not assigned to a particular processor. A global queue of threads is maintained. Each processor, when idle, selects a thread from this queue. Note that load balancing refers to a scheme where work is allocated to processors on a more permanent basis.

  2. Gang Scheduling: A set of related threads is scheduled to run on a set of processors at the same time, on a 1-to-1 basis. Closely related threads / processes may be scheduled this way to reduce synchronization blocking, and minimize process switching. Group scheduling predated this strategy.

  3. Dedicated processor assignment: Provides implicit scheduling defined by assignment of threads to processors. For the duration of program execution, each program is allocated a set of processors equal in number to the number of threads in the program. Processors are chosen from the available pool.

  4. Dynamic scheduling: The number of thread in a program can be altered during the course of execution.

How to check the given molecules are polar or non polar :

If the electronegativity of the two bonded atoms are different then the bond is polar. Although, some molecules contain polar bonds, the molecule may be non-polar. If the polarity of all the bonds present in the molecule are cancel each other then molecule is non-polar.

 

In the given options,

SO2  is polar because the dipole moments on the O do not cancel.

PCl3  is polar because the P-Cl bonds do not cancel out.

CH2Cl2  polar because the C-Cl bonds do not cancel.

 

Hence, in brief, Polar molecules are molecules with net dipole due to the presence of partial positive and partial negative charge.

For example, water is a polar molecule that has partial positive and partial negative charge on it. CO2 is a non polar compound.

 

Therefore, all the given options SO2, CH2Cl2 and PCl3 are Polar molecules.

Q:

Computer storage units smallest to largest?

Answer

The smallest unit of data storage in a computer is called Bit (Binary Digit). Half a byte (four bits) is called a Nibble.


 


1 bit (binary digit) = the value of 0 or 1


8 bits = 1 byte


1024 bytes = 1 kilobyte


1024 kilobytes = 1 megabyte


1024 megabytes = 1 gigabyte


1024 gigabytes = 1 terabyte


1024 terabytes = 1 petabyte


 


Hence, Computer storage units smallest to largest i.e, in ascending order is


 1 bit  <  1 byte  <  1 KB  <  1 MB  <  1 GB  <  1TB  <  1 PB.
