MEANING OF BOOTING

booting is the process of starting a computer. It can be initiated by hardware such as a button press, or by a software command

Types of Booting

1) Warm Booting: when the System Starts from the Starting or from initial State Means when we Starts our System this is called as warm Booting. In the Warm Booting the System will be Started from its beginning State means first of all, the user will press the Power Button , then this will read all the instructions from the ROM and the Operating System will b Automatically gets loaded into the System.

 

2) Cold Booting: The Cold Booting is that in which System Automatically Starts when we are Running the System, For Example due to Light Fluctuation the system will Automatically Restarts So that in this Chances Damaging of system are More. and the System will no be start from its initial State So May Some Files will b Damaged because they are not Properly Stored into the System.

Strategies& Activities:

Step :Teacher revises the previous topic.

Step 2:Teacher introduces the new topic.

Step3:Teacher explains the new topic.

Step4: Teacher welcomes pupils questions.

Step5: Teacher evaluates the pupils.

Assessment & Evaluation:

1. Define booting the computer

2. State the types of booting

WRAP UP(CONCLUSION) Teacher goes over the topic once again for better understanding.

Assignment:

1. Define booting.

2. State the 2 types of booting.

TYPES OF BOOTING

Cold Boot: when the user switches on a computer after it has been power off completely,

Warm Boot: when the user restarts the computer.

When the booting process takes place, it copies kernel and important instructions of an operating system from hard disk to main memory (RAM). The kernel is the most important part of the operating system that manages memory and devices, maintains computer clock, starts applications.

It assigns compute resources like devices, programs, data, and information also. The kernel also remains in memory permanently when the computer starts.

Steps In the Booting Process

Booting is a process of switching on the computer and starting the operating system. Six steps of the booting process are BIOS and Setup Program, The Power-On-Self-Test (POST), The Operating System Loads, System Configuration, System Utility Loads and Users Authentication.

booting process

1: BIOS and Setup Program

2: The Power-On-Self-Test (POST)

3: The Operating System (OS) Loads

4: System Configuration

5: System Utility Loads

6: Users Authentication

Step 1: BIOS and Setup Program

ROM (read-only memory): it is a permanent and unchanging memory also

BIOS (basic input/output system ): the part of the system software that includes the instructions that the computer uses to accept input and output

Load: to transfer from a storage device to memory. The ROM loads BIOS into the computer’s memory

Setup program: a special program containing settings to control hardware.  Furthermore,  the program can only be accessed while the BIOS information is visible

Step 2: The Power-On-Self-Test (POST)

POST (Power-On Self-Test): a series of tests conducted on the computer’s main memory, input/output devices, disk drives, and the hard disk.

BIOS conducts Power-On-Self-Test to check the input/ output system for operability.

The computer will produce a beeping sound if any problem occurs. An error message will also appear on the monitor

Step 3: The Operating System (OS) Loads

BIOS  searches for the operating system.

Setting in CMOS: complementary metal oxide semiconductor determines where to look for the operating system.

In this step, the operating system’s kernel is also loaded into the computer’s memory.

The operating system takes control of the computer and begins loading system configuration information.

Step 4: System Configuration

Registry: a database to store information about peripherals and software

Peripheral: a device connected to a computer

Drive: a utility program that makes peripheral devices function properly

The operating system’s registry configures the system.

In this step, drivers are also loaded into memory.

Step 5: System Utility Loads

System utilities are loaded into memory.

Volume control

Antivirus software

PC card unplugging utility

Step 6: Users AuthenticationAuthentication or user login occurs

Username

Password

After all this process, the user interface starts, enabling user interaction with the computer and its programs also.

Strategies& Activities:

Step :Teacher revises the previous topic.

Step 2:Teacher introduces the new topic.

Step3:Teacher explains the new topic.

Step4: Teacher welcomes pupils questions.

Step5: Teacher evaluates the pupils.

Assessment & Evaluation:

1. Define booting the computer

2. State the types of booting

WRAP UP(CONCLUSION) Teacher goes over the topic once again for better understanding.

Assignment:

1. Define booting.

2. State the 2 types of booting.
