VLAN tagging is essential for segmenting and organizing network traffic within a single physical network infrastructure. It allows network administrators to logically group devices into separate broadcast domains, or VLANs, regardless of their physical location on the network. By assigning VLAN tags to network frames, switches can direct traffic more efficiently, improving network performance and … Read more

Wireshark captures packets by monitoring network interfaces in promiscuous mode, allowing it to intercept and record all packets passing through the interface. When Wireshark is running, it captures packets by listening to the network traffic on the specified interface or interfaces, capturing both incoming and outgoing packets for analysis. To capture HTTP packets specifically in … Read more

Wireshark is primarily used as a network protocol analyzer, allowing users to capture and inspect the data packets traveling over a computer network. Its core functionality includes capturing network traffic in real-time or from stored files, analyzing packet contents at various layers of the OSI model, and providing detailed insights into network protocols and communications. … Read more

Netstat is a command-line utility used to display network statistics on Unix-like operating systems and Windows. It provides information about network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. Netstat allows users to monitor active network connections, view open ports, and track network traffic in real-time. The netstat statistics command, often used with … Read more

Commonly used network services encompass a range of functionalities that facilitate communication, resource sharing, and access to information across networks. These services include: Email: Email services enable users to send and receive messages electronically over networks, often using protocols like SMTP (Simple Mail Transfer Protocol) for sending and IMAP/POP3 for receiving emails. Email is widely … Read more

Netstat is used for a variety of network monitoring and diagnostic tasks. One primary use is to display active network connections, both incoming and outgoing, along with corresponding protocol information such as TCP or UDP. This functionality helps administrators and users identify which services are communicating over the network, monitor established connections, and understand the … Read more

Network services encompass a broad range of functionalities provided by computer networks to facilitate communication, resource sharing, and access to distributed resources. These services play crucial roles in enabling users and devices to interact, collaborate, and access information across networks. Some key functions of network services include: Communication: Network services enable users to communicate and … Read more

Ping works by sending ICMP (Internet Control Message Protocol) echo request packets to a specified destination, typically a remote host or server. The ICMP echo request asks the destination to send an ICMP echo reply back to the sender. When the destination receives the echo request, it responds with the echo reply if it’s configured … Read more

In messaging contexts, “ping” can refer to sending a quick message or notification to someone to get their attention or prompt a response. It originated from the concept of radar or sonar pings used in detecting objects by emitting a signal and waiting for a response. In messaging apps or platforms, “ping” often implies a … Read more

Bandwidth is used to measure the capacity of a network connection to transfer data. It quantifies the amount of data that can be transmitted over a network in a given amount of time, typically expressed in bits per second (bps). High bandwidth allows for faster data transfer, supporting activities that require substantial data flow, such … Read more
