Hi,
 
   I am very new to Bitcoin. Read some articles and trying to understand how Bitcoin works.

  Could someone spend some time to explain about below questions.

   1. What are the systems the BitCoin Network contains and who are managing those systems.

   2. I think any body can work as a Minor if he/she uses a PC/Laptop to add a transacation in a Block.
     If  no minor is doing this mining work, will the receives still receives his Bitcoin ( if a sender sends ).
     Can you explain how the receiver can receive the BitCoins.

    3. How the sender and receiver knows the transactions are Confirmed. Will they get any information.


Thanks in Advance.
