Wi-Fi, short for Wireless Fidelity, is a technology that allows devices to wirelessly connect to a local area network (LAN) using radio waves. It enables wireless communication between devices such as computers, smartphones, tablets, printers, and smart home devices within a specific range of a Wi-Fi access point or router. Wi-Fi is primarily used to … Read more

SSH (Secure Shell) in TCP refers to the use of TCP (Transmission Control Protocol) as the underlying transport protocol for SSH connections. TCP provides reliable, connection-oriented communication between SSH client and server endpoints, ensuring that data is transmitted accurately and in sequence. SSH uses TCP to establish encrypted sessions for secure remote access, file transfer, … Read more

NTP, which stands for Network Time Protocol, is a widely used protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. It is designed to synchronize the time of day among a set of distributed time servers and clients. NTP, or Network Time Protocol, is the full name of the protocol used … Read more

SSH (Secure Shell) is used primarily for secure remote access, allowing users to connect to and manage remote systems securely over an untrusted network, such as the internet. It provides encrypted communication channels between a client and a server, ensuring confidentiality, integrity, and authentication of data transmitted during the session. SSH is widely used by … Read more

Remote Desktop Protocol (RDP) is used for remotely accessing and controlling computers or virtual desktops over a network. It allows users to connect to a remote system’s desktop environment and interact with it as if they were physically present at the remote machine. RDP enables users to access files, applications, and resources on remote computers, … Read more

TFTP (Trivial File Transfer Protocol) and FTP (File Transfer Protocol) are both protocols used for transferring files over a network, but they differ significantly in their features and capabilities. TFTP is a simpler, lightweight protocol designed for basic file transfer operations, whereas FTP is a more comprehensive protocol that supports a wider range of functionalities, … Read more

A P2P network operates by connecting individual computers (peers) directly to each other without the need for a central server. Peers in the network can act as both clients and servers, sharing resources such as files, computing power, or bandwidth. Each peer communicates directly with other peers to exchange data or perform tasks. P2P networks … Read more

A cloud service provider (CSP) operates by offering various cloud computing services over the internet to individuals, organizations, and businesses. CSPs typically maintain large data centers with extensive computing resources, including servers, storage, networking equipment, and virtualization technology. They provide scalable and on-demand access to these resources through different service models such as Infrastructure as … Read more

OSPF (Open Shortest Path First) has three main states: Down, Init, and Full. These states represent different stages in the OSPF neighbor relationship process. The Down state indicates that OSPF is not operational or the interface is down. In the Init state, OSPF routers exchange hello packets to discover potential neighbors. Once bidirectional communication is … Read more

A hybrid cloud integrates private and public cloud environments to allow data and applications to be shared between them. Organizations typically use a hybrid cloud to combine the scalability and flexibility of public cloud services with the security and control of private cloud infrastructure. This setup enables businesses to leverage both cloud types based on … Read more
