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.

Takardar Darasi

Whenever you log into email, bank online or join a video call, you are relying on data being transferred securely and on the system trusting that you are really you. Weak security has real costs: stolen money, leaked private messages, devices crippled by malware. Examiners ask you to judge whether a password is strong, choose an authentication method and weigh the advantages and disadvantages of meeting online, so the reasoning in this topic turns directly into marks and into safer habits.
