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
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
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
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
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
Subnetting serves several purposes in networking, primarily aimed at improving efficiency, scalability, and security within IP networks. By dividing a large network into smaller subnets, administrators can manage IP address allocation more efficiently, reduce broadcast traffic, and optimize network performance. Subnetting also supports hierarchical network designs, allowing organizations to organize and segregate network resources based … Read more
Fiber optic refers to a technology that uses thin strands of glass or plastic fibers to transmit data in the form of light pulses. It is used primarily for its capability to transmit large amounts of data over long distances at very high speeds. Fiber optic cables can carry signals over greater distances without signal … Read more
The purpose of using NFC (Near Field Communication) is to enable short-range wireless communication between electronic devices, typically within a distance of a few centimeters. NFC facilitates convenient and secure interactions between devices, allowing them to exchange data, initiate transactions, and perform various actions with a simple tap or proximity. NFC is used for a … Read more
EIGRP, or Enhanced Interior Gateway Routing Protocol, is a Cisco proprietary routing protocol used in computer networks, particularly in IP networks. It is designed to support multiple network layer protocols and facilitate efficient routing within a network. EIGRP operates within a single autonomous system (AS), allowing routers within the same AS to dynamically share routing … Read more
The purpose of the POP (Post Office Protocol) protocol is to enable email clients to retrieve emails from a mail server. POP operates in a client-server model where the email client connects to the POP server to download messages from the server to the client’s local device. Once downloaded, emails are typically removed from the … Read more
