1. MAC Address Moaz mohamed

2. MAC Address is a unique identifier assigned to network interfaces for communications on a network. It is a hardware address that is used to uniquely identify devices on a network. MAC addresses are typically assigned by the manufacturer of the network interface and are used for routing data packets to their intended destinations on a local network. Each MAC address is made up of 6 pairs of hexadecimal digits, separated by colons or hyphens. 

3. types of mac address types of mac address Types of MAC address 1-Unicast : - In unicast , data is sent from one sender to one specific receiver. The data is intended for a single recipient. Unicast communication is commonly used for point-to-point communication in networks. 2-Broadcast : -  In broadcast communication, data is sent from one sender to all devices on the network. This is a one-to-all communication method where the data is intended for all recipients on the network. Broadcast communication is used for tasks such as network discovery or sending information to all devices on a network.

4. 3-Multicast :-   In multicast communication, data is sent from one sender to a specific group of recipients. This is a one-to-many communication method where the data is intended for a select group of recipients who have joined a multicast group. Multicast communication is used for tasks such as streaming media or distributing data to specific groups of devices on a network .

5. Relation between MAC address and hacker  MAC addresses are generally secure since attacks are difficult to implement and require extensive technological know-how. However, it can be used to monitor your location, disrupt your internet access, or even perform a man-in-the-middle attack.

6. How to protect your MAC address ? 1. Turn off Wi-Fi when on the move To prevent your device from sharing MAC address with another device 2. MAC spoofing   is a technique used to change or falsify (MAC) address of a network interface. This can be done for various reasons, such as bypassing network security measures, impersonating another device on the network, or gaining unauthorized access to a network. By changing the MAC address of a device, an attacker can potentially evade network filters or gain access to restricted areas of a network. It is important for network administrators to be aware of MAC spoofing and implement measures to detect and prevent this type of unauthorized activity on their networks .
