A browser proxy is a tool or service that acts as an intermediary between a user’s web browser and the internet. It intercepts requests from the browser, forwards them to the destination server on behalf of the user, receives the response, and then forwards that response back to the browser. This allows users to access … Read more

A web proxy is a server that acts as an intermediary between a user’s web browser and the internet. It facilitates indirect access to web content by forwarding requests from the browser to the destination server and returning the response to the user. This allows users to mask their IP addresses, access content blocked by … Read more

The purpose of the TLS (Transport Layer Security) record layer is to ensure secure communication between client and server over a network by providing confidentiality, integrity, and authentication of data transmitted. It achieves this through encryption, message authentication codes (MACs), and cryptographic algorithms. The record layer encapsulates higher-level protocol data into records, which are then … Read more

SSH (Secure Shell) and SSL (Secure Sockets Layer) are cryptographic protocols used to secure communications over networks, but they serve different purposes and operate at different layers of the networking stack. SSH is primarily used for securely accessing and managing remote computers or servers over an insecure network. It provides encrypted communication channels, authentication mechanisms, … Read more

The purpose of the SNMP (Simple Network Management Protocol) service is to enable centralized monitoring and management of network devices and systems. SNMP allows network administrators to gather information, configure settings, and monitor the performance of network devices such as routers, switches, servers, and printers. By providing a standardized method for communication between network devices … Read more

The purpose of an internet gateway is to provide a connection between a private network, such as a local area network (LAN), and the internet. It serves as an entry and exit point for network traffic between internal network devices and external internet resources. Internet gateways typically include routing and network address translation (NAT) functionalities … Read more

A peer-to-peer network is a decentralized network architecture where individual nodes (computers or devices) communicate directly with each other without relying on a central server. Each node in the network can act as both a client and a server, sharing resources such as files, computing power, or services with other nodes in the network. This … Read more

A gateway serves as a point of entry or exit between two networks, facilitating communication by translating protocols or data formats to ensure compatibility between different networks. It operates at the network layer of the OSI model, where it can perform tasks such as routing data between networks, translating between different network protocols, and providing … Read more

Cloud storage refers to a service model where data is stored, managed, and maintained remotely on servers accessible over the internet. It allows users to store and retrieve data from anywhere with an internet connection, eliminating the need for physical storage devices like hard drives or flash drives. Cloud storage providers typically offer scalable storage … Read more

The purpose of the IMAP protocol (Internet Message Access Protocol) is to enable email clients to access and manage emails stored on a remote mail server. Unlike POP (Post Office Protocol), which typically downloads emails to a local device and removes them from the server, IMAP allows users to view, organize, and synchronize emails across … Read more
