Mac address





 Mac address 

A MAC (Media Access Control) address is a unique identifier assigned to the network interface of a device. It is used to identify devices on a network, and it is usually stored in the device's hardware, such as the network card. A MAC address is made up of six pairs of hexadecimal digits, separated by colons, hyphens, or periods. For example, a MAC address might be 00:1A:C2:7B:00:A0.

The MAC address is used by the network to identify and communicate with a specific device on the network. It is usually assigned by the manufacturer of the device and is stored in the device's hardware. The MAC address is used in the networking process to identify the device and to ensure that the data is sent to the correct device.

Each device on a network has a unique MAC address, which allows devices to communicate with each other and with the network. MAC addresses are used in the OSI (Open Systems Interconnection) model, which is a framework that defines how devices on a network communicate with each other. The MAC address is used at the data link layer of the OSI model, which is the second layer from the bottom.

What is network

NETWORK TECH WORLD What is network  A network is a group of devices, such as computers, servers, and printers, that are connected together and able to communicate with each other. Networks can be classified based on their size and scope, such as a local area network (LAN), which is a network that is confined to a small area, such as a single building or campus, or a wide area network (WAN), which is a network that spans a large geographical area, such as a city or a country. Networks can also be classified based on their communication protocols, such as the Internet, which is a global network that uses the Internet Protocol (IP) to connect devices around the world.

This is the same as typing the url into the search box. spell: will spell check your query and search for it. stocks: will lookup the search query in a stock index. filetype: will ...

Network Protocols

NETWORK TECH WORLD A network protocol is a set of rules and standards that define how devices on a network should communicate with each other. Network protocols govern everything from the type of cable that is used to connect devices to the way in which data is transmitted between them. There are many different types of network protocols, each of which serves a specific purpose. Some common examples include: TCP (Transmission Control Protocol): This is a connection-oriented protocol that is responsible for breaking up data into packets, transmitting the packets over the network, and reassembling the packets at the destination. TCP is a reliable protocol that ensures that all packets are delivered to their destination. IP (Internet Protocol): This is a connectionless protocol that is responsible for routing packets between devices on a network. IP is an unreliable protocol that does not guarantee that packets will be delivered to their destination. HTTP (Hypertext Transfer Protocol): Th...
