What is a MAC Address? MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). It is also known as a physical or hardware address. It identifies the hardware manufacturer and is used for network communication between devices in a network segment. MAC Address usually consists of six groups of two hexadecimal digits. The network adapters or network interface cards always come with a MAC address which is fed into hardware, usually in read-only memory (ROM), or BIOS system. The physical address is stored into the NIC by its manufacturer, that is why this address is also called a burned-in address (BIA) or ethernet hardware address.

The first three sets of two hexadecimal numbers in a MAC Address identifies the card manufacturer, and this number is called OUI (organizationally unique identifier). OUI is always the same for NICs manufactured by the same company...

Advantage of Linux OS Let us now discuss some advantages of Linux in brief: 1. Open Source: One of the main advantages of Linux is that it is an open source operating system i.e. its source code is easily available for everyone. Anyone capable of coding can contribute, modify, enhance and distribute the code to anyone and for any purpose. 2. Security: Linux is more secure in comparison to other operating systems such as Windows. Linux is not completely secure as there is some malware for it also but it is less vulnerable than others. Every program in Linux whether an application or a virus needs authorization from the administrator in the form of a password. Unless the password is typed virus won’t execute.

There are many distributions available to use acc...

Official ROM- Provided by mobile manufacturers, tested and stable as well as safe. It provided warranty as well from manufacturer.

Official is not necessarily better than unofficial. For many popular devices, both exists, and the developer for unofficial versions will add tweaks to differentiate, e.g. a custom kernel, slimmed down build (i.e. removed some preinstalled apps), themed to the developer's liking. This is what I'm doing monthly as ...
