*          Booting Up

 

In your computer lab session in the school, your teacher has handed you an assignment. Once you enter the computer room, you must make your computer ready for doing work. When the computer is first turned on, the system performs a POST (Power-On Self Test) which tests various components in the computer. The POST checks the entire memory and tests the connections to the various hardware devices attached, such as the keyboard, the disk drive, etc. If any problem occurs with any of the connections to the hardware devices or with the memory, the POST program reports this on the screen. The process of loading or copying the operating system is called Booting Process. A boot sequence is the initial set of operations that the computer performs when power is switch on. The boot loader typically loads the main OS for the computer. Every time a computer is switched on, a series of steps have to be performed before the user can interact with it.    

 

 

 

*     The following are the steps to work on computer

  • Switch on the Power Supply Button
  • Switch on the UPS
  • Switch on the Monitor
  • Wait for the message on the Monitor
  • Then wait for the cursor on the Monitor Screen
  • Computer is ready to work  

Now let us go over the steps one by one. In the computer room, first you will see the computer in an off-position.  

 

 

 

*      You need to turn on the following switches to start a computer:

  • Power Supply Switch: Turn on the switch at the source of the power supply. The stabilizer will start receiving the current.
  • On/Off Switch of UPS: Turn on switch of UPS. The UPS is used to regulate the flow of current.
  • On/Off Switch of CPU: Turn on switch of CPU. The current will start passing through the system.
  • On/Off Switch of the Monitor: Turn on switch of monitor. Look at the monitor and you will see some messages. After these messages you will see the cursor on the monitor screen. Now you can begin working on the computer.
  • Thus we saw the entire Booting Up process to make the computer ready to work.

(D) Steps in option (D) are arranged Incorrectly. Therefore, option (D) is Incorrect.

(E) Steps in option (E) are arranged Incorrectly. Therefore, option (E) is Incorrect.  

 

 

 Given below the statements about Booting process. Select the correct statements.

1. The PAST checks the entire memory and tests the connections to the various hardware devices attached, such as keyboard, disk drive, etc.

2. The process of loading or copying the operating system is called Booting Process.

3. A boot sequence is the initial set of operations that the computer performs when power is switch on.

(A) Only statement 1                                     

(B) 2 and 3

(C) 1 and 3                                                          

(D) All of these

Answer: (b)

Explanation

Correct Option:

(B) Statements 2 and 3 are correct. Therefore, option (B) is correct.

Incorrect Options:

(A) Statement 1 is Incorrect. Because POST checks the entire memory and tests the connections to the various hardware devices attached. Therefore, option (A) is Incorrect.

(C) Statement 1 is Incorrect but statement 3 is correct. Therefore, option (C) is Incorrect.
