Work Step by Step
a. **Cloud computing**: Cloud computing refers to the delivery of computing services, including storage, servers, databases, networking, software, and more, over the internet ("the cloud"). Instead of owning and maintaining physical hardware or infrastructure, users can access these services on-demand from a cloud provider, paying only for the resources they use. Cloud computing offers scalability, flexibility, cost-effectiveness, and often better performance compared to traditional on-premises infrastructure.
b. **Hot spot**: A hotspot, in the context of technology, refers to a location where wireless internet access is available, typically through Wi-Fi. It enables users with Wi-Fi-enabled devices such as laptops, smartphones, or tablets to connect to the internet wirelessly. Hotspots are commonly found in public places like cafes, airports, hotels, and libraries, as well as in private spaces like homes and offices.
c. **Top-level domains (TLDs)**: Top-level domains are the highest level of domain names in the hierarchical Domain Name System (DNS) of the internet. They appear at the end of a web address, following the last dot, such as ".com", ".org", ".net", ".edu", etc. TLDs serve as categorization for websites, indicating the type of organization or entity associated with the domain. For example, ".com" is commonly used for commercial entities, ".org" for non-profit organizations, ".gov" for government agencies, and so on.
d. **Secure Shell (SSH)**: Secure Shell is a cryptographic network protocol used for secure communication between two computers, typically a client and a server. SSH encrypts data transmitted over the network, preventing eavesdropping and unauthorized access to sensitive information. It provides various authentication methods, including passwords, public key cryptography, and two-factor authentication, ensuring secure remote access, file transfer, and command execution on remote systems. SSH is widely used in managing and administering servers and other networked devices securely.
