Computer Awareness MCQ Quiz - Objective Question with Answer for Computer Awareness - Download Free PDF

The correct answer is Dial-up line

Key Points

• Dial-up line:
  • This was one of the earliest types of internet access. A dial-up connection is called a 'switched line' because it uses the switching feature of the telephone network to establish a connection to the internet.
  • A computer modem dials a phone number of the Internet Service Provider's (ISP) modem and data is transferred via this telephone connection.

Additional Information

• Satellite: This method of internet access involves communication between a small dish antenna at your location and a geostationary satellite orbiting the earth approximately 22,300 miles above the equator. Signals are transmitted to and from the satellite to provide internet access. Satellite internet access can provide a connection in rural and remote areas where other types of internet connections are not available.
• Leased line: This is a private bidirectional or symmetric telecommunications line between two or more locations provided in exchange for a monthly rent. It is typically used by businesses to connect geographically distant offices. Unlike dial-up connections, a leased line is always active. The fee for the connection is a fixed monthly rate and its speed is usually guaranteed.
• ISDN (Integrated Services Digital Network): ISDN is a set of communication standards to transmit voice, video, and data over traditional copper telephone lines. It was designed to support a wide range of services including telephone, video conferencing, and data transmission. It allows multiple digital channels to be operated simultaneously through one single line. Like a dial-up line, it uses the phone network, but it provides higher data rates and simultaneous transmission of multiple data streams. ISDN connections are typically switched (on-demand) similar to a dial-up line, but are faster and more efficient.

The correct answer is .xlsx.

Key Points

CC

Key Points

• Carbon copy is referred to as cc. When you wish to send an email to someone other than the primary recipient, you utilize this.
• This keeps them informed while also informing them that they probably don't need to respond to your communication.
• The CC field is used to refer to the concept of the carbon copy as it sends additional copies of a single email to one or more recipients.
• Because your recipients will see your email the same way regardless of which field you use, the TO and CC fields are frequently used interchangeably.

Additional Information Signature:- A person's name written in their own hand to indicate that the writing that comes before it is in line with their wants or intentions.

Subject Line:- The first line of text recipients see when they open your email is the subject line. Make sure it is optimized for your audience because this one line of content frequently determines whether an email is opened or sent directly to the trash.

The correct answer is All of the above

Artificial Intelligence (AI) can indeed be utilized in various spheres of life due to several key abilities. Let's analyze the given options:

• 1. Ability to work in hazardous environments: AI can be deployed in dangerous situations where it would be unsafe for humans, such as in mining, deep-sea exploration, or handling hazardous materials.
• 2. Ability to think like human beings: While AI doesn't think like humans in the truest sense, it can mimic certain human cognitive functions, such as learning, problem-solving, and decision-making, which makes it valuable in applications like customer service, diagnostics, and personalized recommendations.
• 3. Ability to work in artificial environments: AI systems can operate in simulated or controlled environments, such as virtual reality, gaming, and automated testing, which can enhance training, entertainment, and product development.

Given these abilities, the most comprehensive answer is: 4) All of the above

AI's versatility in working in hazardous environments, mimicking human cognitive functions, and operating in artificial environments contributes to its widespread applicability across various fields.
