When securing your computer network, using a software firewall is an essential step. A software firewall is a program that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. It helps prevent unauthorized access and protects your system from malware and cyber-attacks. In this article, we’ll take a look at…
Every device connected to a network has a unique identifier called an IP address. The IP address is used for addressing at the Network layer of the OSI model (internet level of the TCP/IP architecture). It is a unique address of every device connected to the network, more precisely, every network interface on the network….
In this article, we present the 5 best bandwidth monitoring tools for Windows that are specifically designed for network engineers. Bandwidth monitoring is an essential aspect of network administration and management. It helps in tracking the usage of bandwidth and optimizes the network’s performance. The information obtained from bandwidth monitoring can help identify the cause…
MPLS (Multiprotocol Label Switching) in networking is a type of data-carrying technology for high-performance IP networks. MPLS operates at an OSI Model layer that is generally considered to lie between traditional definitions of Layer 2 (data link layer) and Layer 3 (network layer) and thus is often referred to as a “Layer 2.5” protocol. How…
In today’s digital age, networks are a crucial component in the functioning of businesses and organizations. A switch is a fundamental component of a network that plays a vital role in connecting and transmitting data between different devices. So, what is a switch in networking… What is a Switch in Networking? A switch is a…
Nmap is an open-source networking utility (network scanner) used to discover IP addresses (hosts) and open ports on the network by sending packets and analyzing the responses. Nmap started as a Linux utility and was ported to other operating systems including Windows and macOS. Network engineers use Nmap for port scanning, ping sweeps, OS detection,…
Introduction In computer networks and digital communication systems, efficient data transmission between nodes is essential for maintaining optimal performance. Key concepts such as bandwidth, throughput, and delay (Round Trip Time – RTT) play a crucial role in determining the effectiveness of data transfer. Bandwidth refers to the maximum amount of data that can be transmitted…
A network adapter is chipset on circuit boards that provides physical access from the PC to the LAN or Wi-Fi (WLAN) network. The network adapter is also known as Network Interface Card (NIC). If it provides access to wired LAN then UTP or fiber optic cable is used to connect PC to switch. If it’s…
