Network Issues And Communication
Bayani Gaba-gaba
The moment data leaves your device and travels across a network, it becomes a target. Passwords can be guessed, messages can be intercepted and viruses can ride along with an innocent-looking download. Keeping data private and confidential during transfer, and proving that the person at the keyboard really is who they claim to be, are among the most important everyday jobs in computing, and they are tested in almost every ICT paper.
In this lesson you will learn what makes a password strong, and meet the modern alternatives to passwords: zero login, biometrics, magnetic stripe cards, smart cards, and physical and electronic tokens. You will see how anti-malware software finds and quarantines viruses, and how people meet across distances using video, audio and web conferencing, along with the hardware, software and connection each one needs. By the end you will be able to recommend sensible security measures and compare the three kinds of electronic conference.
