An SSL certificate proves your site is who it says it is and encrypts traffic, which gives you the padlock.
Browsers now warn visitors when a site lacks a valid certificate. That warning costs trust and leads. Google also prefers sites that use HTTPS.
Certificates expire and must renew. On older setups a lapsed certificate is a common reason for a sudden Not Secure warning. Modern hosts renew them automatically.
Think Bright hosting includes a certificate for your domain and renews it for you. The padlock stays on without anyone remembering a date.
Hosting is the computer that keeps your website online and hands it to visitors when they type your address.
DNS is the phone book that turns your domain name into the address of the server that holds your site.
Uptime is the share of time your site is actually reachable.
A CDN keeps copies of your site in many cities so visitors get it from somewhere close.
