Several companies provide a *Transport
Layer Security (TLS) or Secure Sockets
Layer (SSL) certificate for e-commerce sites,
sites that process sensitive data, and sites that
require privacy and security requirements.
An SSL certificate consists of a public key and
a private key. The public key encrypts
information and the private key deciphers the
information.

In this lesson, you learned:
 Make sure you use a computer in a way that
supports your comfort, health, and safety. When you
use a computer, take precautions to avoid chronic
physical maladies such as repetitive motion injuries,
eyestrain, and back problems that can arise over
time. Ergonomic design, which adapts equipment
and the workplace to fit the worker, can help to

A virus is a program that has been written, usually
by a hacker, to corrupt data on a computer. The
virus is attached to a file and spreads from one

protect your computer against virus damage, use
up-to-date antivirus software, download and
install security updates for your operating system,
and avoid opening files sent via e-mail from
people you do not know.
