Master Boot Record (MBR) & Globally Unique Identifier Partition (GPT) based partion disks

As a IT Professional you should familiar with these MBR and GPT based  partition disks. 
If you need a install a hard disk on a PC that running windows 7 you can chose two partitioning systems.
Partition schemes are
  • Master Boot Record (MBR) based partition scheme
  • Globally Unique Identifier Partition (GPT) based partition scheme

Master Boot Record (MBR) based partition scheme
In the Master Boot Record you can find the partition table for the disk and master boot code. during the computer start-up process BIOS read MBR and find the which partition is the marked as active in the disk. In the active partition contains operating system.
Limitations of the MBR.
Only four partitions for each disk.
Maximum partition size is 2TB
Can not create a redundancy options.

Globally Unique Identifier Partition (GPT) based partition scheme
GPT based partition avoided limitations of the MBR partitions scheme GPT supports.
128 partitions
Ability to create partition size larger than 2TB
Ability to create redundancy options.

How to reduce laptop temperature

01. Keep the laptop on a hard surface: Place the laptop on a hard surface like a desk or a table to ensure that the airflow is not restricted. Avoid placing the laptop on soft surfaces like a bed or a sofa as they can block the airflow and cause overheating 02. Use a laptop cooling pad: Laptop cooling pads are designed to improve airflow and reduce heat buildup. They come in various sizes and designs and can be easily attached to the laptop's bottom. 03. Clean the air vents: Over time, the air vents on the laptop can get clogged with dust and debris, restricting airflow and causing overheating. Use a can of compressed air to blow out any dust or debris from the vents. 04. Avoid running too many programs simultaneously: Running too many programs simultaneously can cause the laptop to work harder, generating more heat. Try to close any programs that are not in use. 05. Adjust power settings: Adjust the power settings of the laptop to reduce the workload on the system.

Master Boot Record (MBR)

The Master Boot Record (MBR) is a small but essential section of a hard drive that is responsible for booting up an operating system. It is located at the very beginning of the hard drive and contains information about the partition table and boot loader. The MBR consists of three parts: Boot loader code The boot loader code is the first piece of code that is executed when the computer boots up, and it is responsible for finding and loading the operating system. Disk signature Disk signature is a unique identifier that is used to differentiate between different hard drives. Partition table Partition table contains information about the layout of the hard drive, including the size and location of each partition. When a computer boots up, the BIOS (Basic Input/Output System) reads the MBR from the hard drive and loads the boot loader code into memory. The boot loader code then searches for the active partition and loads the operating system from that partition into memory. The MBR is a c
