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
BGP (Border Gateway Protocol) uses TCP (Transmission Control Protocol) as its transport layer protocol for several reasons. TCP provides reliable, connection-oriented communication between BGP peers, ensuring that BGP messages are delivered accurately and in sequence. BGP relies on TCP’s mechanisms such as error detection, retransmission of lost packets, and flow control to maintain a stable … Read more
ARP (Address Resolution Protocol) is used in computer networking to map IP addresses to MAC addresses within a local network segment. Its primary function is to resolve or discover the hardware (MAC) address of a device based on its IP address. This allows devices to communicate directly on the same subnet without relying on higher-layer … Read more
