What is digital Multimeter and how to use!

What is digital Multimeter and how to use!

A digital multimeter (DMM) is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries.
Digital multimeters long ago replaced needle-based analog meters due to their ability to measure with greater accuracy, reliability and increased impedance. Fluke introduced its first digital multimeter in 1977.
Digital multimeters combine the testing capabilities of single-task meters—the voltmeter (for measuring volts), ammeter (amps) and ohmmeter (ohms). Often they include a number of additional specialized features or advanced options. Technicians with specific needs, therefore, can seek out a model targeted for particular tasks.

Computer Hardware Disassembling


Disassembling the computer system

Detach the power cable:
The disassembling of the computer system starts with externally connected device detachment. Make sure the computer system is turned off, if not then successfully shut down the system and then start detaching the external devices from the computer system. It includes removing the power cable from electricity switchboard, then remove the cable from SMPS (switch mode power supply) from the back of the CPU Cabinet. Do not start the disassembling without detaching the power cable from the computer system. Now remove the remaining external devices like keyboard, mouse, monitor, printer or scanner from the back of CPU cabinet.

Computer Hardware Tools

Computer Hardware Tool Kits 

I doubt the rise in tablets, laptops and mini PCs will see the end of people building, repairing or modifying their computers, despite many being sealed, so a computer tool kit is invaluable. There are a number of kits available to buy and you only need a couple of tools to do 99% of the tasks you’ll ever attempt. You may even have many of the tools.

Types of Network Cable

Despite advances in wireless technologies, many computer networks in the 21st century still rely on cables as a physical medium for devices to transfer data. Several standard types of network cables exist, each designed for specific purposes.
