The correct answer is Secondary.

• USB Pendrive is a Secondary type of storage device.

Key Points

• The full form of USB is Universal Serial Bus.
• USB is a plug and play interface that allows a computer to communicate with external and or devices.
• The first commercial release of Universal Serial Bus (version 1.0) was in January 1996.
• USB connectors come in different shapes and sizes. They are of various types which include  standard USB, Mini USB, and Micro USB, have two or more variations of connectors.

Additional Information

• A primary storage device is a storage medium that holds a memory for short periods of time while a computer is running.
• Random-access memory (RAM) and cache are both examples of a primary storage device.
• Tertiary storage devices comprise high-capacity data archives designed to include vast numbers of removable media, such as tapes or optical discs.

The correct answer is Simple Mail Transfer Protocol.

Key Points

• Simple Mail Transfer Protocol:
  • An SMTP (Simple Mail Transfer Protocol) server is an application that's primary purpose is to send, receive, and/or relay outgoing mail between email senders and receivers.
  • SMTP is part of application layer of TCP/IP protocol. Using a process called “store and forward,” SMTP moves your email on and across networks. It works closely with something called Mail Transfer Agent (MTA) to send your communication to right computer and email inbox.

Important Points

• IMAP (Internet Message Access Protocol) is an email protocol that deals with managing and retrieving email messages from receiving server.
• Since IMAP deals with message retrieval, you will not be able to use IMAP protocol to send emails. Instead, IMAP will be used for receiving messages.
• POP stands for Post Office Protocol. And number three stands for “version 3,” which is latest version and most widely used — hence term “POP3.”

The correct answer is 'File Allocation Table'

Key Points

• File Allocation Table (FAT):
  • FAT is a file system architecture used in many computer systems and most memory cards.
  • It is known for its simplicity and has been standard file system for many versions of Microsoft Windows.
  • The name "File Allocation Table" comes from its use of a table that operating system maintains to keep track of storage of files on disk.

The correct answer is Joint Photographic Experts Group (JPEG).

Key Points

• JPEG stands for Joint Photographic Experts Group.
• JPEG is a standard image format for containing lossy and compressed image data.
• JPEG is a unique compression feature, that allows JPEG files to be used widely on  Internet, Computers, and Mobile Devices.

Additional Information 

• Some important abbreviations used in Computer:
  • BIOS - Basic Input Output System
  • CAD - Computer-Aided Design
  • EDVAC - Electronic Discrete Variable Automatic Calculator
  • EPROM - Erasable Programmable Read-Only Memory
  • FORTRAN - FORmula TRANslation
  • GPRS - General Packet Radio Service 

?The correct answer is Portable Network Graphics.

• Portable Network Graphics is full form of PNG in 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 computer.
• PNG is also known as a successor of GIF format images.
• It uses 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 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 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.

Additional Information 

• JPEG (or JPG) - Joint Photographic Experts Group.
• GIF - Graphics Interchange Format.
• TIFF - Tagged Image File Format.
• BMP - BitMaP.
• SVG - Scalable Vector Graphics
• PSD - Photoshop Document.
• PDF - Portable Document Format.
• EPS - Encapsulated Postscript.
• RAW -Raw Image Formats
• AI - Adobe Illustrator Document.

The correct answer is ?Network Access Protection

Key Points

• Network Access Protection (NAP) is a Microsoft technology used in some Windows operating systems to ensure that computers attempting to access a network meet certain health requirements, such as having updated antivirus or recent patches installed.
• It leverages components like System Health Agents on clients and Network Policy Servers to evaluate and enforce se requirements.
• Non-compliant devices may be granted limited network access for remediation purposes, ensuring overall network security.

Note that NAP has been deprecated in newer Windows versions.

The correct answer is Fiber Distributed Data Interface

Key Points

• Fiber Distributed Data Interface (FDDI) is a standard for data transmission that utilizes a fiber optic cable. It was developed in mid-1980s by American National Standards Institute (ANSI) to exploit high-speed capabilities of fiber optics in local area networks (LANs).
• FDDI was primarily used as a high-speed backbone technology due to its support for high bandwidth. It operates over a dual ring network — meaning, it has a primary and a secondary communication ring. Information typically flows on primary ring in one direction, with secondary ring serving as a backup in case of a primary ring failure, hence term "dual" in its name.
• FDDI uses a token ring protocol to control access to network and allows data to be transmitted at speeds of up to 100 mbps up to 200 kilometers. It has mostly been superseded in favor of newer, higher-speed technologies such as Ernet and Wi-Fi, but its principles are still used and applicable in certain contexts.

The correct answer is TCP/IP.

• The standard network protocol of Internet, TCP/IP, stands for Transmission Control Protocol/Internet Protocol.
  • The Internet Protocol part of standard refers to addressing of data message packets.
  • Additional protocols that operate within TCP/IP framework include UDP, HTTP, and FTP.

Key Points

• The Internet Protocol (IP) is principal communications protocol in  Internet protocol suite for relaying datagrams across network boundaries.
• Its routing function enables internetworking and essentially establishes Internet.

The correct answer is Common Business Oriented Language. 

• COBOL stands for Common Business Oriented Language.
  • It is first developed in 1960 by CODASYL Committee (Conference on Data Systems Languages).
  • It is primarily designed for use in business-oriented applications.
