Domain names use friendly names like "www.example.com" to represent the IP addresses of web servers and pages. Domain names have different levels, with the top-level domain (TLD) like .com or .org at the end of the address. Below the TLD are second-level domains like "example" and sometimes third-level subdomains. TLDs can indicate geographical location using country codes or functionality. Web portals bring together information from multiple sources in a uniform way and can be accessed from different devices. Portals are important as they efficiently deliver customized information while increasing interaction and eliminating multiple logins. Common types of portals include jobs, news, travel, e-commerce, social networks,
