Explanation:
In the Logo programming language, the cursor is represented by a graphical object known as the "turtle". The turtle can be moved around the screen using various commands and can be used to draw shapes and perform other operations.

The turtle cursor in Logo is a key feature of the language and is often used to introduce programming concepts to beginners. The turtle can be controlled to move in different directions, turn at angles, and perform basic arithmetic operations such as addition and subtraction.

Logo and its features:
Logo is a programming language that was developed in the late 1960s to teach children the basics of programming. It uses a simple syntax and a graphical interface, making it easy to understand and use. Logo is known for its turtle graphics, which allow users to control a cursor called a turtle to create drawings and animations.

Logo provides a set of commands and procedures that can be used to control the turtle and perform various operations. These commands include moving the turtle forward or backward, turning it left or right, lifting or lowering the turtle's pen, and performing arithmetic operations.

The turtle cursor:
The turtle cursor in Logo is represented by a graphical object that can be moved around the screen. The turtle starts at a specific position, usually in the center of the screen, and can be controlled to move in different directions.

The turtle can be moved forward or backward a certain number of steps using the "FD" (forward) and "BK" (backward) commands. It can also be turned left or right using the "LT" (left) and "RT" (right) commands, which specify an angle of rotation.

Basic arithmetic operations:
Logo allows users to perform basic arithmetic operations such as addition and subtraction using the turtle cursor. This is done by specifying the arithmetic operation and the operands in the Logo command.

For example, to perform addition, the "+" symbol is used along with the operands. The turtle cursor can be moved forward by the sum of the operands. Similarly, subtraction can be performed using the "-" symbol, where the turtle cursor moves backward by the difference of the operands.

The name of the cursor:
In Logo, the cursor is commonly referred to as the "turtle". This term comes from the original implementation of Logo, where a physical turtle-shaped robot was used to draw on paper. The turtle cursor in Logo is named after this robot and is a central concept in the language.

Therefore, the correct answer is option B) Turtle.

Protocol is a set of rules that are used to perform a particular task. Which one of the following is the most common internet protocol?
  • a)
    TCP/IP
  • b)
    HTML
  • c)
    IPX/SPX
  • d)
    NetBEUI
  • e)
    None of these
Correct answer is option 'A'. Can you explain this answer?

Understanding Internet Protocols
Internet protocols are essential for enabling communication between devices on a network. Among these protocols, TCP/IP stands out as the most common.
What is TCP/IP?
- TCP/IP stands for Transmission Control Protocol/Internet Protocol.
- It is the foundational suite of protocols that governs how data is transmitted over the internet.
- Developed in the 1970s, TCP/IP has become the standard for networking.
Key Features of TCP/IP:
- Interconnected Networks: TCP/IP allows different types of networks to connect and communicate with each other, forming the internet.
- Error Handling: The protocol ensures that data is sent accurately and can recover from errors during transmission.
- Scalability: It supports a vast number of devices, making it suitable for everything from small networks to the global internet.
Comparison with Other Protocols:
- HTML: This is a markup language used for creating web pages, not a communication protocol.
- IPX/SPX and NetBEUI: These are older protocols used primarily in local area networks (LANs) and are not commonly used for internet communication.
Conclusion:
- TCP/IP is vital for the functioning of the internet, making it the most widely adopted protocol.
- Understanding TCP/IP is crucial for anyone interested in networking and internet technologies.
In summary, TCP/IP is the backbone of internet communication, enabling efficient data exchange and connectivity across diverse platforms and devices.

UPS is power equipment provides power backup to computers. It also enables uninterrupted power supply. UPS stands for ____
  • a)
    Universal port serial            
  • b)
    Up-line provider service
  • c)
    Uninterruptible power supply  
  • d)
    Uniform page source
  • e)
    None of these      
Correct answer is option 'C'. Can you explain this answer?

Explanation:

UPS (Uninterruptible Power Supply):
UPS is a power equipment device that provides backup power to computers and other sensitive electronic equipment. It helps in protecting devices from power surges, spikes, sags, or outages by providing a continuous power supply.

Functionality:
- When the main power source fails, the UPS switches to its internal battery power, ensuring uninterrupted operation of the connected devices.
- It also regulates the voltage fluctuations and provides clean and stable power to the devices.

Importance:
- UPS is crucial for critical systems like servers, data centers, and network equipment as they need continuous power to function properly.
- It helps in preventing data loss, system crashes, and hardware damage due to sudden power failures.

Types of UPS:
- Standby UPS: Provides basic backup power and switches to battery when input power fails.
- Line-interactive UPS: Regulates voltage fluctuations by boosting or reducing the voltage.
- Online UPS: Constantly supplies power from the battery, offering the highest level of protection.

Conclusion:
UPS, which stands for Uninterruptible Power Supply, plays a vital role in ensuring the smooth operation of electronic equipment during power outages or fluctuations. It is an essential device for protecting sensitive devices and preventing data loss.

Answer:

To copy text from one document to another in MS Word, the shortcut key used is Ctrl + C.

Explanation:

Copying text allows you to duplicate a selected portion of text and place it in another location. This can be done within the same document or in a different document. MS Word provides a convenient shortcut key to quickly copy text without the need to use the menu options.

Steps to copy text using Ctrl + C:

1. Select the text you want to copy by clicking and dragging the cursor over the desired portion of text.
2. Once the text is selected, press the Ctrl key on the keyboard and while holding it down, press the C key.
3. The selected text is now copied to the clipboard, which is a temporary storage area in the computer's memory.
4. Navigate to the document or location where you want to paste the copied text.
5. Place the cursor at the desired location and press the Ctrl key followed by the V key to paste the copied text.

The Ctrl + C shortcut key combination is widely used across various applications to perform the copy operation. It provides a quick and efficient way to duplicate text without the need to manually select the copy option from the menu.

Alternative options:

The other options mentioned in the question (Ctrl + S, Alt + C, and Ctrl + P) are not the correct shortcut keys used for copying text in MS Word.

- Ctrl + S is used to save the document.
- Alt + C and Ctrl + P are not associated with the copy operation in MS Word.

Therefore, the correct answer is option A) Ctrl + C.
