Question Discussion & Solution

The correct answer is Versatility, Diligence.

Key Points

• Versatility is the characteristic of a computer to perform completely different types of work at the same time, whereas diligence makes it to work for hours without boredom or tiredness. 
• Versatility means the capacity of the computer of performing more than one task at the same time.
• Diligence is the capacity of the computer of performing repetitive tasks without getting tired.
• A computer is free from tiredness, lack of concentration, fatigue, etc therefore it can work for hours without creating any errors.

Additional Information

Characteristics of Computer System are:

• Speed - A computer works with much higher speed and accuracy compared to humans while performing mathematical calculations. 
• Accuracy - Computers perform calculations with 100% accuracy. 
• Diligence - A computer can perform millions of tasks or calculations with the same consistency and accuracy. 
• Versatility
• Reliability
• Memory

The correct answer is Margins.

Key Points

• A margin is a space separating text or other elements from the edge of the paper commonly adjusted through the page setup.
• Most programs allow for the top, bottom, left, and right margins to be set. 
• By increasing the size of the margins, you decrease the available space on the page that text can occupy.
• In other words, a page with bigger margins has less room for text.
• If you decrease the size of the margins, the page can accept more text.

Additional Information

• Justify is a text that is both left-aligned and right-aligned. 
  • In Microsoft Word, you can use the Ctrl + J keyboard shortcut to justify any text.
• A trapdoor is a concealed means of bypassing security to gain access to a restricted part of a computer system.
  • For example, a programmer may insert a piece of code that would allow them access to a computer or secure area using a password that only they know.

The correct answer is Gigahertz.

Key Points

• The speed of the CPU is measured in Gigahertz.
  • A central processing unit or CPU enables your computer to interact with all of the applications and installed programmes.
  • CPU interprets the program’s instructions and creates the output that is the interface.
  • The performance of the CPU has a major effect on the speed at which programs run.
  • Clock speed (also “clock rate” or “frequency”) is an important attribute to measure the performance of a processor. 
  • A higher clock speed means a faster CPU.  
  • The CPU processes many instructions from different programs every second.
  • The clock speed measures the number of cycles the CPU executes per second.
    • ​It is measured in GHz (gigahertz).
  • A “cycle” is technically a pulse synchronized by an internal oscillator.
  • During each cycle, billions of transistors within the processor open and close.
  • A CPU with a clock speed of 3.2 GHz executes 3.2 billion cycles per second.  

The correct answer is Machine Language.

Key Points

• Low-level languages are also known as Machine Language.
• A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture commands or functions in the language map closely to processor instructions.
• Generally, this refers to either machine code or assembly language.

Additional Information

• Examples of low-level programming languages:
  • C and C++ are now considered low-level languages because they have no automatic memory management. 
• Low-level languages were developed first, and high-level languages came along later.
• High-level languages are more easily understood by humans mostly coding languages like Java.

The correct answer is the Date picker.

Key Points

• A Date picker is a mini-calendar from which data - entry clerks can enter a date.
• ​The date picker allows users to enter a date either through text input or by choosing a date from the calendar.
• The date picker is made up of several components, directives, and the date implementation module that work together.
• A data entry clerk is a member of staff employed to enter or update data into a computer system. Data is often entered into a computer from paper documents using a keyboard.
