Here are some things I would do to protect my email account: - Use a strong, unique password that is different from any other account. Don't reuse passwords. - Enable two-factor authentication to add an extra layer of security beyond just a password. This requires a code from an authenticator app or text message when logging in from a new device. - Be cautious of email attachments and links, even from senders I know. It's best not to open attachments or click links unless I'm expecting them. - Watch out for phishing scams pretending to be from my email provider, banks, or other companies trying to steal my login credentials. Pay attention to spelling errors or strange URLs.

5. STRUCTURE OF THE
INTERNET
The internet is like a massive web of
interconnected computers and devices spread
across the world. These devices include servers,
routers, and your own computer or smartphone.
They're connected through cables, wireless
signals, and satellites. There's no central authority
controlling the internet; instead, it's decentralized,
with many different networks working together.
When you access a website or send an email, your
data travels through this network, hopping from
one device to another until it reaches its
destination.
