A MAC address is a unique identifier assigned to a network interface controller for use as a network address in communications within a network segment.

• MAC stands for Media Access Control

• It is a 48-bit address

• It is used to uniquely identify devices on a network

• A router can have multiple MAC addresses, one for each interface

• MAC addresses are usually represented in hexadecimal format

• Example: 00:1A:2B:3C:4D:5E

IPv6 is the latest version of Internet Protocol. There are no classes in IPv6.

• IPv6 is a 128-bit address scheme, compared to IPv4's 32-bit address scheme.

• IPv6 addresses are written in hexadecimal notation.

• IPv6 uses a different header format than IPv4.

• Unlike IPv4, there are no classes in IPv6 addressing.

DNS stands for Domain Name System. It is a system that translates domain names into IP addresses.

• DNS is like a phonebook for the internet, translating human-readable domain names into machine-readable IP addresses.

• DNS works by using a hierarchical system of servers to look up and resolve domain names.

• When you type a domain name into your browser, your computer sends a request to a DNS resolver, which then queries DNS servers to find the IP address associated with that domain ...read more

SMB stands for Server Message Block, a protocol used for file sharing and printer sharing in a network.

• SMB is used for sharing files and printers between computers in a network.

• It allows multiple users to access the same resources simultaneously.

• SMB operates on the application layer of the OSI model.

• It uses TCP/IP as the underlying transport protocol.

• SMB has evolved over the years and the latest version is SMB3.

• Examples of SMB implementations include Windows file sharing and ...read more

Routing protocol is a set of rules that determine how data is transmitted between devices on a network.

• Routing protocols are used to facilitate communication between different networks.

• They determine the best path for data to travel from one network to another.

• Examples of routing protocols include OSPF, BGP, and RIP.

• Routing protocols can be classified as either interior gateway protocols (IGPs) or exterior gateway protocols (EGPs).

A router is a networking device that forwards data packets between computer networks.

• Routers connect multiple networks together.

• They determine the best path for data packets to travel.

• Routers use routing tables to make forwarding decisions.

• They provide network address translation (NAT) to allow multiple devices to share a single public IP address.

• Routers can prioritize certain types of network traffic for better performance.

• Examples of routers include Cisco routers, TP-Link r...read more

NFS server is a network file system server that allows clients to access files over the network as if they were on the local machine.

• NFS stands for Network File System.

• It is a distributed file system protocol that allows a user on a client computer to access files over a network as if those files were on the local computer.

• The NFS server is responsible for managing the shared file system and making it available to clients.

• It is commonly used in Unix and Linux environments.

• Exa...read more

PST and OST files are both used by Microsoft Outlook to store email data, but they differ in their location and usage.

• PST files are stored locally on a user's computer and can be used for archiving or backing up email data.

• OST files are used for offline access to email data and are stored on a server.

• PST files can be imported or exported to transfer email data between computers or accounts.

• OST files are automatically created when a user sets up an email account in Outlook and...read more
