Hardware Identification ppt | Concept | Components of a Computer:

Hardware  Identification

Hardware identification is a security measure used by the Windows operating system on activation. A string called a Hardware Identifier (HWID) is generated by the operating system when it is installed for the first time. This identifier represents all the hardware devices attached to the host computer and is transferred to Microsoft. Every 10 days and after every reboot, a new HWID is generated which is compared with the one generated at the time of installation. If both the IDs are close to each other, then the operating system assumes that it is running on the same device. Otherwise, the operating system needs to be activated by Microsoft.

 

 
Components of a Computer:

  •Central Processing Unit (CPU)     

 •Random Access Memory (RAM)  

 •Graphics Card

 •Motherboard

 

Central Processing Unit (CPU)

The brains of computer that processes and calculates information required by the operating system. The CPU is attached to the motherboard.
 

Random Access Memory (RAM)

Primary memory of a computer that stores short term information for programs that is currently in use and demanded by the operating system. RAM is attached to the motherboard. 

 

Graphics Card

Processing unit for graphics that converts information to colour outputs on a display. Graphic cards often include a video output such as HDMI, VGA or DVI to connect to an external display. Graphic cards are connected to the motherboard.

 

Motherboard

The body of the computer that connects all external and internal computers together. The motherboard connects internal components such as RAM or the CPU and external components such as USBs. Most information of a computer passes through the motherboard.

what is OSI model | what are seven layer of OSI model | function of OSI model. OSI Reference Model INTRODUCTION Stands for open system interconnection. It has 7 layers. Each layer having specific functionality to perform. All layers work collaboratively to transmit the data from one person to another across the globe.                            All 7 layers of OSI model explain briefly: Physical layer To move data in the form of electromagnetic signals across a transmission medium. Responsible for movements of individual bits from one hop (Node) to next hop. Both data can be either analog or digital. Transmission media of data which can be wired or wireless.   Data link layer It is responsible for moving frames from one hop to the next. Responsible for error free transfer of data frames. Controls the flow of data. Network layer The network layer works for the tra...
