  3. Application Peripheral Interface

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

API stands for Application Programming Interface. It's a set of protocols and tools for building software applications, defining how software components should interact.

Multiple choice

The _______ is also called kernel.

  1. file system

  2. nucleus

  3. input/output

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The nucleus is indeed another term for the kernel in operating systems. The kernel is the core component that manages system resources and hardware-software interaction.

Multiple choice

The ______ of the operating system manages processes.

  1. file system

  2. kernel

  3. input/output

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The kernel is the core component of an operating system that manages processes, memory, and hardware resources. The file system handles storage organization, while input/output operations manage data transfer between devices and the system.

Multiple choice

Virus gets activated by the

  1. hard disk

  2. host program

  3. floppy disk

  4. CPU

  5. -
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

It is a device connected to a computer network, which offer information resources, services and applications to users on the network.

Multiple choice

The program which we write in the edit window is known as ______.

  1. object file

  2. source file

  3. executable file

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A source file contains the original program code written by a programmer in a high-level language before compilation. It's called 'source' because it's the original human-readable code. The compiler translates source files into object files, which are then linked into executable files. The edit window in IDEs is where source code is written and modified.

Multiple choice

Directions: For this question, select the best of the answer choices given.

A recent survey found that more computers than copies of computer programs were purchased by Germans last year. The best interpretation of this finding is that the practice of illegally duplicating commercial computer programs is widespread among Germans. Each of the following, if true, would counter some reasonable objection to the interpretation advanced above EXCEPT that

  1. few German computer users write their own computer programs

  2. there are few free noncommercial computer programs available in Germany

  3. some Germans purchase computers outside of Germany for use in Germany, and such purchases were counted in the survey

  4. the typical German computer user has several commercially written computer programs on his or her computer

  5. many Germans legally make duplicates of commercial computer programs, but such duplicates were counted as purchased copies in the survey
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is an EXCEPT question asking which option does NOT counter an objection to the software piracy interpretation. The argument claims more computers than programs sold proves widespread illegal duplication. Option C states some Germans buy computers abroad that get counted in the survey - this would actually STRENGTHEN the interpretation by showing more computers in Germany without corresponding program sales, not counter it. Options A, B, D, and E all provide alternative explanations (users writing own programs, free programs, multiple programs per user, legal duplicates) that would counter the piracy interpretation.

Multiple choice

A computer virus is

  1. a chemical that attacks silicon

  2. a micro-organism that destroys integrated circuits

  3. data that the computer fails to handle

  4. a special kind of computer programme
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A computer virus is a malicious software program that replicates itself by modifying other computer programs and inserting its own code. It is not a chemical or biological entity. The term 'virus' is metaphorical, referring to how it spreads from program to program like a biological virus. Options A, B, and C are incorrect - viruses are purely digital code entities designed to damage systems or steal data.
