Secure Socket Layer (SSL) is a cryptographic protocol designed to provide secure communication over a computer network. It ensures that data transmitted between a client (e.g., a web browser) and a server (e.g., a website) remains private and integral. SSL establishes an encrypted connection by encrypting data before it is transmitted and decrypting it upon … Read more
UDP (User Datagram Protocol) is a lightweight transport layer protocol used in computer networking. It provides a connectionless and unreliable communication service where data packets are sent without establishing a connection or ensuring delivery confirmation. UDP is often used for applications that prioritize speed and efficiency over reliability, such as real-time multimedia streaming, online gaming, … Read more
SMTP (Simple Mail Transfer Protocol) is a protocol used for sending email messages between servers over the internet. It is a fundamental part of the email transmission process, handling the relay of outgoing emails from email clients or other mail servers to the recipient’s mail server. SMTP ensures that emails are routed correctly across networks … Read more
TLS (Transport Layer Security) and SSL (Secure Sockets Layer) are cryptographic protocols designed to secure communication over networks, particularly the internet. The main difference between TLS and SSL lies in their versions and security features. TLS is an updated and more secure successor to SSL, designed to address vulnerabilities and weaknesses found in earlier SSL … Read more
WAN (Wide Area Network) and LAN (Local Area Network) are two types of networks with distinct characteristics and purposes. A LAN typically covers a smaller geographic area, such as a single building, office, or campus. It connects devices like computers, printers, and servers within a confined space using Ethernet cables or wireless technology. LANs are … Read more
There are typically three types of WAN based on the technology used for connectivity: Leased Lines: Leased lines are dedicated point-to-point connections established by telecommunications providers. They provide consistent bandwidth and reliability but can be costly, as they require paying for the entire bandwidth regardless of usage. Circuit-Switched Networks: These networks establish temporary connections through … Read more
A proxy server is used primarily to act as an intermediary between a client (such as a web browser or application) and the internet. It facilitates indirect connections to other network services, masking the client’s IP address and enhancing privacy and security. Proxy servers intercept requests from clients and forward them to the destination server … Read more
A LAN (Local Area Network) network address refers to the IP address and subnet configuration used within a localized network environment, typically confined to a single building, home, office, or campus. This address is part of a reserved private IP address range that allows devices within the LAN to communicate with one another and connect … Read more
Basic load balancing refers to the process of distributing incoming network traffic across multiple servers or resources within a computer network to ensure optimal utilization and performance. It is a fundamental technique used in networking and server management to enhance reliability, maximize throughput, and minimize response time for users accessing applications or services. The difference … Read more
Cloud computing refers to the delivery of computing services—including servers, storage, databases, networking, software, and more—over the internet (“the cloud”). Instead of owning their own computing infrastructure or data centers, individuals or organizations can rent access to everything they need from a cloud service provider. In simple terms, cloud computing means storing and accessing data … Read more
