Computer Awareness MCQs

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 other devices.
• The first commercial release of the 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 the 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 TCP/IP.

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

Key Points

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

The correct answer is Application software

Important Points

• MS Office, Photoshop, and Animagic are examples of Application software
• MS Office is a software bundle provided by Microsoft.
• It includes software like MS Word, MS Excel, MS Powerpoint, MS Outlook, MS Access, MS One Note, and others.

Additional Information

• Photoshop is a powerful photo editing tool by Adobe.
• An Operating System (OS) is an interface between a computer user and computer hardware.
• An operating system is software that performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.

The correct answer is RAM.

• RAM is a volatile memory while ROM is a non-volatile memory.
• While RAM allows the computer to read data to run applications, ROM stores all the application which is required to start the computer initially.
• RAM can perform both read and write operations on the information stored in it.
• ROM allows the user to read the information but not write the information. It is used to store permanent information, which is non-erasable.
• MROM, PROM, EPROM, and EEPROM are different types of ROMs.

The correct answer is Programmable read-only memory

Key Points

• PROM stands for Programmable Read Only Memory.
• Read only memory (ROM) is a type of memory that is used in electronics and computers.
• It is a non-volatile memory, that is, information stored in such a memory is permanent and cannot be changed.
• Other two types of ROM are
  • Electrically Erasable Programmable ROM (EEPROM)
  • Erasable Programmable ROM (EPROM)

Additional Information

• Primary memory can be divided into RAM (Random Access Memory) and ROM (Read Only Memory)

The correct answer is option 3 i.e ​Ctrl + Z.

• Ctrl + Z is the shortcut key to undo an action in MS Word.
• Ctrl+W is the shortcut key to close the current window.
• Ctrl+B is the shortcut key to Bold highlighted text.
• Ctrl + U is the shortcut key to underline a text.

There are different components in the computer system. they all have their own working mechanisms. some component takes input, some process the data and some give output. all these components combine and make our work easier, comfortable, and convenient.

For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices. Devices for communication between computers, such as modems and network cards, typically perform both input and output operations.

Hence, we may conclude that the right answer be like: -

The correct answer is option 5, i.e. File Transfer Protocol.

• FTP - File Transfer Protocol
• It is a standard Internet protocol for transmitting files between computers on the Internet over TCP/IP connections.
• It is a client-server model architecture or protocol.
• Using FTP, a client can upload, download, delete, rename, move and copy files on a server.

The most common image file formats, the most important for cameras, printing, scanning, and internet use, are JPG, TIF, PNG, and GIF. JPG is the most used image file format.

Full Form

JPG = Joint Photographic Experts Group

TIF / TIFF = Tagged Image File Format

PNG = Portable Network Graphics

GIF = Graphics Interchange Format

Sequence should be follow is:
