​The correct answer is Open Platform Communication.

• Open Platform Communication is the full form of OPC.

Additional Information

Open Platform Communication(OPC)

• It is platform-independent and ensures the continuous flow of information across multiple vendor devices.

OCR (Optical Character Recognition)

• OCR has also known as Optical Character Reader or text recognition.
• An OCR device is made up of hardware and software combinations.
• Hardware of OCR (optical scanner or a circuit board) copies and reads the text, whereas the software deals with advanced processing.
• The software can also make use of artificial intelligence to use advanced methods of intelligent character recognition (ICR), like the ability to identify language or style of handwriting.
• It is designed to convert scanned paper documents, or images of documents captured by a digital camera into machine-readable, editable, and searchable data.

• V in VDSL stands for very high speed.

The correct answer is HyperText Transfer Protocol

Key Points

• HTTP is an application protocol used for data communication on the World Wide Web (WWW).
• It provides a standard for web browsers that facilitates users to exchange information over the internet.
• HTTP works as a request-response protocol in the client-server computing model.
• A web browser, for example, may be the client, and an application running on a computer hosting a website may be the server.
• The client submits an HTTP request message to the server, and the server provides a response message in return.

The correct option is 4 i.e., Asymmetric Digital Subscriber Line.

Additional Information

• The full form of ADSL in computer terminology Asymmetric Digital Subscriber Line.
• Unlike regular dialup phone service, ADSL provides continuously-available, "always-on" connection. 
• ADSL is generally offered at downstream data rates from 512 Kbps to about 6 Mbps. 
• A form of ADSL, known as Universal ADSL or G.lite, has been approved as a standard by the ITU-TS. 

The correct answer is Helix.

• Multitasking is the capability of the operating system of running several applications at the same time.
• It is therefore deeply related to the OS capability for managing shared resources, and in particular for arbitrating conflicts resulting from resource over-commitment.
• In a multitasking environment, the totality of the computer’s resources (memory, files, CPU time) is allocated to different applications, and they are managed in such a way that each one of them gets a share according to specific priority policies.

Key Points

• In 1961, the LEO III emerged, which was a British computer machine that had enabled the use of multitasking in operating systems. 
• The term multitasking, when paired with an operating system, refers to the users being allowed to accomplish more than one computative task, for instance.
• Types of Multitask Operating Systems are:
  • Preemptive Multitasking.
  • Cooperative Multitasking.

Important Points

• An Operating System does the following to carry out activities related to multitasking:
  • Initially, the user will give instructions to the operating system or to a program/application directly, and they will receive an immediate response.
  • To display this quick response, the operating system handles multitasking by “slicing” some of the processors operating capability to that program.
• Advantages of a Multi-Task Operating System are:
  • Time-sharing.
  • Handles Multiple Users.
  • Protected Memory.
  • Efficient virtual memory.
  • Programs can run in the background.

  • It is primarily designed for use in business-oriented applications.

Additional Information

• Some important Abbreviations

​The correct answer is Portable Network Graphics.

• Portable Network Graphics is the full form of PNG in the computer image format.

Key Points

• PNG (Portable Network Graphics) PNG (Portable Network Graphics)
• PNG is a format for storing bit-mapped or raster images on the computer.
• PNG is also known as a successor of GIF format images.
• It uses the less compression technique to save images like GIF files but without copyright issues.
• It contains a bitmap of indexed color so it is also called a bit-mapped image.
• Portable Network Graphics Format was developed in early 1995.
• PNG form was created by a team working under Thomas Boutell.
• The main reason behind its development was the limitation of 256 colors only in GIF.
• PNG has a file extension ".png".
• PNG provides low-resolution images that look good and load quickly.
• The amount of transparency can be controlled.
• The format supports interlacing, and it can be developed faster than the GIF format.
• PNG format also supports Gamma correction.
• Images can be saved by using true color.
• It can also be saved by using palette and grayscale formats provided by GIF.
