Ethics and Safety Measures in Computing

It acts as a middleman, inspects all incoming traffic, and only grants access after verification

Step 1: A Firewall is a network security device that controls network access between an untrusted zone (internet) and a trusted zone (private network). Step 2: A Proxy Firewall specifically acts as a MIDDLEMAN between the user and the internet. Step 3: It accepts ALL incoming traffic requests first, then inspects them carefully. Step 4: Only after a thorough inspection does it decide whether to grant or deny access and forward information to the destination computer. Step 5: Option A is wrong — a firewall does not block ALL traffic, only suspicious traffic. Option C is wrong — firewalls filter

Creating a password using your date of birth for easy remembering

Step 1: The question asks for the option that is NOT a safe measure — so we need to find the WRONG advice. Step 2: Using strong antivirus software IS a recommended safety measure against hacking.

Software Piracy

Step 1: Identify what Arjun did — he downloaded paid software for free from an unauthorised source and distributed it to others without buying a license. Step 2: Software Piracy is defined as making and distributing copies of software without buying the required license or copyright.

Step 4: Phishing involves fraudulently obtaining sensitive information — not applicable here. Cyberbullying involves harassing someone online. Spamming involves s

The trail of data that records all activities performed by a user on the internet

Step 1: The term 'Digital Footprint' uses the analogy of a footprint — just as walking on sand leaves marks, using the internet leaves a trail of data. Step 2: Digital footprint includes websites visited, emails sent, information submitted online, videos watched, and more. Step 3: This trail is recorded on electronic devices and internet servers. Step 4: It can be advantageous as it helps detect fraudulent activities, but it can also be harmful if accessed by unauthorised persons. Step 5: Options A, C, and D all describe other things — connected device records, virus tracking, and software log
