1. Write a note on other virus like programs (10)

Other Virus-Like Programs

• There are other computer programs that are similar to viruses in some ways but different in some others
• Three types:
• Logic- or time-bombs
• Worms

Logic- or Time-Bombs

• It executes its payload when a predetermined event occurs
• Example events:
• A particular word or phrase is typed
• A particular date or time is reached

Worms

• Harmless in the sense that they only make copies of themselves on the infected computer
• Harmful in the sense that it can use up available computer resources (i.e. memory, storage, processing), making it slow or even completely useless

Designing, writing, or propagating malicious code or participating in any of the fore-mentioned activities can result in criminal prosecution, which in turn, may lead to jail terms and fines!

Q2. What is an intelligent system? (2 marks)

Q3. What is a compiler? Write its one benefit over interpreter? (5 marks)

Answer: Compiler: Compiler translates the program written in a HLL in one go. The translated code is then used by the up whenever the program needs to be run. To run a program you've written, e.g. in JAVA, it must first be translated into machine code so the computer can read it. This is what compilers and interpreters do. However, compilers convert the code all at once, save it, and then run it; whereas interpreters translate the code one line at a time, as it is run. Interpreters tend to result in faster translating of code so they are used mostly for debugging. This is because if you used a compiler, you'd have to re-compile your entire project every time you changed one little thing.

Q8. Write down the advantages of Natural Language Processing. (5 marks)

Answer: If your question is more specifically about prolog vs the more commonly seen OO languages I would argue that you're really comparing apples to oranges - the "advantage" (such as it is) is just a different way of thinking about the world, and sometimes changing the way you ask a question provides a better tool for solving a problem.
