Question Discussion & Solution

The correct answer is Arithmetic Logic Unit.

Key Points

•  Register
  • A register is a quickly accessible location available to a computer's processor.
  • Registers usually consist of a small amount of fast storage.
  • Some registers have specific hardware functions and may be read-only or write-only.
• ​Arithmetic Logic Unit.
  • Arithmetic Logic Unit is a combinational digital circuit.
  • It performs arithmetic and bitwise operations on integer binary numbers.
  • ALU can be designed to perform complex functions.

Additional Information

• Central processing unit
  • It is the main processor or it is electronic circuitry that executes instructions comprising a computer program.
  • The CPU performs basic arithmetic logic, controlling, and input/output operations specified by the instructions in the program.
  • The individual physical CPU processor cores can also be multithreaded to create additional virtual or logical CPUs.
• Control Unit
  • The control unit is a component of a computer's central processing unit that directs the operation of the processor.
  • It tells the computer's memory, arithmetic logic unit.
  • The control unit may include a binary counter to tell the control unit's logic what step it should do.
• Memory unit
  • A memory unit is a component of a computer system.
  • It is used to store data, instruction and information.
  • It is also known as a main/primary/internal memory.
  • There are two types of memory-:
    1. Read only memory.
    2. Random-access memory.

The correct answer is Kernel.

Key Points

• The first program loaded on start-up and manages computer system resources is Kernel.
• A kernel is the central part of an operating system.
• It manages the operations of the computer and the hardware, most notably memory and CPU time.
• There are five types of kernels:
  • A microkernel, which only contains basic functionality
  • A monolithic kernel, which contains many device drivers
  • Hybrid Kernel
  • Exokernel
  • Microkernel

Additional Information

• Resources under the Operating System control:
  • The processor.
  • Main memory.
  • Input/Output Device.
  • Secondary storage devices.
  • Communication devices and ports. 

The correct answer is Mailing Tab > Start mail merge group > Start mail.

Key Points

• Mail Merge
  • It consists of combining mail and letters and addressed envelopes or mailing labels for mass mailings from a form letter.
  • This feature is usually employed in a word processing document which contains fixed text and variables.
• Mail Merge is a useful tool that allows you to produce multiple letters, labels, envelopes.
• It also has name tags and more using information stored in a list, database, or spreadsheet.
• When performing a Mail Merge, we will need a Word document.
• We can start with an existing one or create a new one.
• We also need a recipient list, which is typically an Excel workbook or we will create it by selecting the Recipient option.
  • Where we will write the name, address, and mail of each recipient.

Additional Information

• MS Word
  • It is developed by Microsoft.
  • It was released on 25 October 1983 for the first time.
  • It is a graphical word processing program that users can type with.
  • It has helpful tools to make documents, resumes, contracts.
  • This is one of the most commonly used programs under the office suite. 

The correct answer is Insert > Illustration > Chart.

Key Points

• How to create Charts
  • To create a simple chart in PowerPoint, click insert> Chart and pick the chart you want.
  • Click the placeholder that you want to contain the chart.
  • On the Insert Tab, in the illustrations click the chart.
  • In the Insert Chart dialog box, click a chart and then click ok.

Additional Information

• MS PowerPoint
  • It is a presentation program used to present data and information by using text, diagrams with animation, images, and transitional effects in the form of slides.
  • It is developed by Robert Gaskins and Dennis Austin.

The correct answer is Paint Brush.

Key Points

• BASIC:
  • This programming language was first designed by John G. Kemeny and Thomas E. Kurtz in 1964.
  • The full form of BASIC is - Beginner's All-Purpose Symbolic Instruction Code.
  • It is generally used for scientific and engineering operations.
  • The introduction of newer machines with far greater capabilities made this language nearly obsolete and its upgraded version called Visual BASIC was released by Microsoft in 1991.
• ​C++:
  • ​The programming language was created by Bjarne Stroustrup in the mid-1980s as an extension to the C language.
  • It is an object-oriented language having two main components - direct mapping of hardware and zero-overhead abstractions.
  • The other languages like Java etc were influenced by C++.
• ​JAVA:
  • ​The programming language was designed by James Gosling at Sun Microsystems and was first released in the year 1995.
  • Java language is not platform-dependent and can be used to develop android applications.
  • The most recent version of Java, i.e. Java SE 16 got released in March 2021.
• PAINT BRUSH:
  • Paint is software that enables users to create basic graphic art on their systems.
  • The software has been developed by Microsoft and is found in all the versions of Microsoft Windows.
  • Recently in April 2021, Microsoft has made Microsoft Paint updateable from the Microsoft Store.
