Question Discussion & Solution

The correct answer is Application software.

Key Points

• Spreadsheets, photo editing, PowerPoint, word documents, etc, are examples of Application software.
  • Application software, or app for short, is software that performs specific tasks for an end-user.
  • Effectively, if the user is interacting directly with a piece of software it is application software.
    • For example, Microsoft Word or Excel is application software, as are common web browsers such as Firefox or Google Chrome.
  • It also includes the category of mobile apps, including communication apps such as WhatsApp or games such as Candy Crush Saga.

Additional Information

• System Software
  • System software is a type of computer program that is designed to run a computer's hardware and application programs.
  • If we think of the computer system as a layered model, the system software is the interface between the hardware and user applications.
  • The operating system is the best-known example of system software.
  • The OS manages all the other programs on a computer.
  • System software is used to manage the computer itself.
    • It runs in the background, maintaining the computer's basic functions so users can run higher-level application software to perform certain tasks.
    • Essentially, system software provides a platform for application software to be run on top of.
• System software generally includes the following features:
  • High speed
    • System software must be as efficient as possible to provide an effective platform for higher-level software in the computer system.
  • Hard to manipulate
    • It often requires the use of a programming language, which is more difficult to use than a more intuitive user interface (UI).
  • Written in a low-level computer language
    • System software must be written in a computer language the central processing unit (CPU) and other computer hardware can read.
  • Close to the system
    • It connects directly to the hardware that enables the computer to run.
  • Versatile
    • System software must communicate with both the specialized hardware it runs on and the higher-level application software that is usually hardware-agnostic and often has no direct connection to the hardware it runs on. 
• The platform is hardware and software architecture that acts as a foundation or base upon which other applications, processes, or technologies are developed.
  • In computing, platform refers to basic hardware i.e., computer system, and software i.e., the operating system on which software applications are often run. 

The relation is:

1) Sports : Ground → Sports are organised in ground.

2) Rubber : Eraser → Rubber is used to erase writings on paper.

3) Cinema : Screen → Cinema is shown on screen

4) Drama : Stage → Drama is played on stage.

Hence, Rubber : Eraser is the correct answer.

The correct answer is Mercury.

Key Points

• Mercury is the closest planet to the Sun.
• The planet probably received this name because it moves so quickly across space.
• Temperature variations on Mercury are the most extreme in the solar system ranging from 90 K to 700 K.
• Mercury is the second densest major body in the solar system, after Earth.

Important Points 

• The solar system is made up of the sun and everything that orbits around it, including planets, moons, asteroids, comets, and meteoroids.
  • It extends from the sun, called Sol by the ancient Romans, and goes past the four inner planets, through the Asteroid Belt to the four gas giants and on to the disk-shaped Kuiper Belt and far beyond to the teardrop-shaped heliopause.
  • Scientists estimate that the edge of the solar system is about 9 billion miles (15 billion kilometers) from the sun.
  • Beyond the heliopause lies the giant, spherical Oort Cloud, which is thought to surround the solar system.

Additional Information 

•  The sun is at the center of our solar system and is its largest object, accounting for 99.8% of the solar system's mass.
  • Our sun is a giant, raging ball of fire powered by nuclear reactions, and it provides the energy that sustains life on Earth.
  • The life-giving star is a yellow dwarf star made up of gas: about 91% hydrogen and 8.9% helium, according to NASA.
  • Compared with other stars, the size of the sun is relatively small and it's just one of the hundreds of billions of stars in our home galaxy, the Milky Way. 

The correct answer is Desktop Publishing.

Key Points

• DTP stands for Desktop Publishing.
• It is a publishing software used to create high-quality printed material for individuals, businesses, and organizations.
• The DTP software provides good control over the design and layout of a page as compared to the word processor. 
• Types of DTP:
• DTP is divided into five categories, which are
  • Software for page layout
  • Graphics for software
  • Website for software editing image
  • Website for a publishing system
  • Word processing app
