Network

There are four primary types of networks based on their geographical scope and coverage: Local Area Network (LAN): A LAN is a network that covers a small geographic area, typically within a single building or campus. It connects computers, servers, printers, and other devices to facilitate data sharing, communication, and resource sharing within a limited … Read more

IP mirroring involves duplicating IP traffic from one source to another destination. This process allows monitoring or analyzing network traffic without disrupting normal operations. It’s commonly used for debugging, security analysis, or network performance monitoring. Port mirroring, also known as SPAN (Switched Port Analyzer) or port monitoring, involves forwarding a copy of network packets from … Read more

Network hardware consists of various components that enable communication and data transfer within computer networks. Here are seven common pieces of network hardware: Router: A router is a networking device that forwards data packets between computer networks. It operates at the network layer (Layer 3) of the OSI model and determines the best path for … Read more

Port mirroring is used primarily for network monitoring and analysis purposes. It allows administrators to capture and inspect network traffic passing through a specific switch port without interrupting normal network operations. This is essential for troubleshooting network issues, monitoring for security threats, or analyzing network performance. Port mirroring typically does not significantly affect network performance … Read more

A network device refers to any hardware component or equipment used to facilitate communication and data transmission within a computer network. These devices play crucial roles in connecting computers, servers, printers, and other devices to enable data sharing, resource access, and communication across the network. Network devices can operate at different layers of the OSI … Read more

The four types of cloud computing are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Function as a Service (FaaS). These categories define different levels of abstraction and services offered by cloud providers, ranging from basic infrastructure and operating systems to fully managed applications and serverless computing … Read more

A SMB client, or Server Message Block client, is software or a component within an operating system that enables devices to access files, printers, and other shared resources on a network using the SMB protocol. SMB is a network communication protocol used primarily by Windows-based computers to share files, printers, and other resources over a … Read more

An SSL certificate, or Secure Sockets Layer certificate, is a digital certificate that authenticates the identity of a website and encrypts data transmitted between the website and its visitors. It ensures that sensitive information such as login credentials, credit card details, and personal data remains secure from eavesdropping and tampering. The primary purpose of an … Read more

OSPF (Open Shortest Path First) is a dynamic routing protocol used in computer networks to efficiently exchange routing information between routers. It calculates the shortest path to destination networks based on link costs and network topology, using a link-state routing algorithm. OSPF is widely used in large-scale networks due to its scalability, fast convergence, and … Read more

ARP (Address Resolution Protocol) primarily operates at Layer 2 (data link layer) of the OSI model and is responsible for resolving IP addresses to MAC addresses within a local network segment. It does not strictly correspond to either Layer 3 or Layer 4 but is essential for facilitating communication between devices on the same network. … Read more
