What is the purpose of VLAN Tagging?

VLAN tagging serves the purpose of identifying and segregating network traffic into distinct virtual LANs (VLANs) within a single physical network infrastructure. It enables network administrators to logically divide a physical LAN into multiple VLANs based on criteria such as department, function, or security requirements. VLAN tagging assigns unique identifying tags, typically inserted into the … Read more

What is the reason for IP address?

The reason for having IP addresses lies in their fundamental role as unique identifiers assigned to devices within a network. IP addresses enable devices to communicate with each other across interconnected networks, such as the internet or local area networks (LANs). Each device, whether a computer, smartphone, server, or any networked device, requires a distinct … Read more

What is radii in a circle?

The radii of a circle are the line segments that connect the center of the circle to any point on the circle itself. They are all of equal length in a perfect circle, defining its size and shape uniformly from the center outward. Each individual radius of a circle is called a radius. It is … Read more

What is the advantage of Wireshark?

Wireshark offers several advantages as a network protocol analyzer and packet capture tool. One of its primary advantages is its ability to capture and analyze network traffic in real-time, providing detailed insights into the communication between devices and applications on a network. This capability is invaluable for troubleshooting network issues, diagnosing performance bottlenecks, and detecting … Read more

What is the purpose of the subnet mask?

The purpose of the subnet mask in networking is to determine which portion of an IP address corresponds to the network ID and which portion identifies the host ID within that network. Essentially, the subnet mask separates the IP address into two parts: the network portion and the host portion. By applying the subnet mask … Read more

What is the responsibility of SSL certificate?

The primary responsibility of an SSL certificate is to ensure secure communication between a client (such as a web browser) and a server. It achieves this by encrypting data transmitted over the internet, preventing unauthorized parties from intercepting or tampering with sensitive information like login credentials, credit card details, or personal data. SSL certificates play … Read more

What is the result of netstat?

Netstat is a command-line tool used to display network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. It provides a comprehensive view of active network connections, listening ports, and routing information on a system. The result of running netstat includes detailed listings of TCP, UDP, and other network protocols currently in use, along … Read more

What is the significance of subnet?

The significance of subnetting lies in its ability to optimize network management, improve performance, and enhance security. By dividing a larger network into smaller subnets, administrators can efficiently organize and manage network resources based on geographical location, functional requirements, or security policies. Subnetting reduces broadcast traffic within networks, isolates network issues to specific segments, and … Read more

How does WPA2 improve security?

WPA2 (Wi-Fi Protected Access 2) enhances security primarily by using stronger encryption methods compared to its predecessor, WPA. It employs AES (Advanced Encryption Standard) encryption, which is more robust and resistant to various cryptographic attacks, ensuring that data transmitted over Wi-Fi networks is better protected against interception and decryption by unauthorized parties. WPA2 is considered … Read more

What are the strengths of netstat?

Netstat offers several strengths that make it a valuable tool for network diagnostics and monitoring. One of its key strengths is its ability to display detailed information about active network connections, including protocol types (TCP, UDP), local and remote IP addresses, port numbers, and connection states (e.g., established, listening, closed). This visibility helps network administrators … Read more
