What is one purpose of an End User License Agreement?

  1. Allow customers to legally create and sell a new version of the software
  2. Allow customers to legally use the software
  3. Allow customers to legally modify and compile the source code
  4. Allow customers to legally distribute the application to other users

Answer(s): B

Explanation:

AnEnd User License Agreement (EULA)is a legal contract between the software manufacturer and the user.

The primary purpose of a EULA is togrant the user the right to use the software.

It outlines the terms and conditions under which the software can be used.

This can include restrictions on installation, distribution, and modification.

The EULA helps protect the intellectual property rights of the software creator.


Reference:

"Software Licensing Handbook" by Jeffrey I. Gordon.

"Intellectual Property and Open Source" by Van Lindberg.



What is a common characteristic of a proprietary software license?

  1. A business gains the right to modify the software's source code.
  2. A business gains the right to use the software.
  3. A business gains the right to own the software.
  4. A business gains the right to distribute the software freely.

Answer(s): B

Explanation:

Aproprietary software licensetypically grants a business or user theright to usethe software.

Unlike open-source licenses, proprietary licenses do not usually allow modification, redistribution, or reverse engineering.

The software remains the property of the company that created it, and the licensee is only granted specific, limited rights.

Examples:Many enterprise software applications come with proprietary licenses that specify the terms of use.


Reference:

"Open Source Licensing: Software Freedom and Intellectual Property Law" by Lawrence Rosen.

"Proprietary Software Licenses Explained" from Software Engineering Institute.



Which method is frequently used to protect software?

  1. Trademarks
  2. GNU General Public License
  3. Copyrights
  4. Fair use

Answer(s): C

Explanation:

Copyrightsare a common legal method used to protect software.

A copyright gives the creator of the software exclusive rights to use and distribute the software.

It protects against unauthorized copying, modification, and distribution of the software.

Software creators can enforce their copyrights to prevent others from infringing on their intellectual property.

Example:Copyright law is often invoked in cases of software piracy.


Reference:

"Copyright Law for the Internet and Information Technology" by Geraldine Collins.

"Understanding Copyright Law" by Marshall A. Leaffer.



What is the role of the CPU in a computing environment?

Choose 2 answers

  1. Carrying out the instructions of a computer program
  2. Storing data as it is being processed
  3. Directing electrical current over the circuit board
  4. Connecting components to the system unit
  5. Containing an arithmetic logic unit (ALU) that performs arithmetic and logic operations

Answer(s): A,E

Explanation:

TheCentral Processing Unit (CPU)is the primary component of a computer that performs most of the processing inside a computer.

Carrying out the instructions of a computer program: The CPU executes program instructions, which are the basic tasks that tell the computer what to do.

Containing an arithmetic logic unit (ALU): The ALU performs all arithmetic and logic operations, such as addition, subtraction, and comparison.

The CPU also manages data flow between the computer's other components.

It fetches instructions from memory, decodes them, and then executes them, which involves performing calculations and making decisions.

An employee needs to execute a program from the command line.

Which peripheral device should be used?

  1. Keyboard
  2. Hard drive
  3. Speaker
  4. Printer

Answer(s): A

Explanation:

The employee needs to execute a program from the command line, which requires inputting commands into the computer.

The primary device for inputting commands is the keyboard.

Other options like the hard drive, speaker, and printer are not used for inputting commands.

The hard drive is used for data storage.

The speaker outputs sound.

The printer outputs documents.

Therefore, the correct peripheral device for this task is the keyboard.


Reference:

"Computer Fundamentals" by Anita Goel, which discusses input devices and their uses.

"The Principles of Information Systems" by Ralph Stair and George Reynolds, which details peripheral devices and their functions.



Which motherboard component is used for short-term storage of data?

  1. Hard Drive
  2. BIOS
  3. Read Only Memory
  4. RAM

Answer(s): D

Explanation:

Short-term storage of data on a motherboard is managed by Random Access Memory (RAM).

RAM is volatile memory, meaning it temporarily stores data that is actively being used or processed by the CPU.

The other options:

The hard drive is used for long-term storage.

BIOS (Basic Input/Output System) is firmware for hardware initialization.

Read Only Memory (ROM) is used for permanent data storage that doesn't change.

Thus, RAM is the correct answer for short-term data storage.


Reference:

"Computer Organization and Architecture" by William Stallings, which covers the various types of memory.

"Operating System Concepts" by Abraham Silberschatz, Peter B. Galvin, and Greg Gagne, which explains memory management.



Which item is an input device?

  1. Printer
  2. Flash Drive
  3. CD
  4. Scanner

Answer(s): D

Explanation:

An input device is any hardware component that allows a user to enter data into a computer.

A scanner is an input device that converts physical documents into digital format.

The other options:

Printer is an output device.

Flash drive is a storage device.

CD can be both storage and media for input/output depending on the context but is not primarily used for direct data input.

Therefore, a scanner is the correct answer for an input device.


Reference:

"Introduction to Computer Science" by ITL Education Solutions Limited, which discusses input and output devices.

"Digital Fundamentals" by Thomas L. Floyd, which includes information on various peripherals.



In which type of network topology are the networked devices connected to a central device like a hub or switch?

  1. Star
  2. Bus
  3. Mesh
  4. Ring

Answer(s): A

Explanation:

In a star network topology, each network device is connected to a central device like a hub or a switch.

This central device acts as a repeater for data flow.

The other options:

Bus topology uses a single central cable.

Mesh topology involves each device being connected to every other device.

Ring topology connects devices in a circular fashion.

Therefore, the star topology correctly describes a network where devices connect to a central hub or switch.


Reference:

"Data and Computer Communications" by William Stallings, which explains different network topologies.

"Network+ Guide to Networks" by Jill West, Tamara Dean, and Jean Andrews, which covers network configurations.
