Question Discussion & Solution

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 SRAM.

​Key Points

• SRAM memory devices are very much similar, mainly in terms of speed, to the cache memory.
• SRAM stands for Static random-access memory.
• Static random-access memory is a type of random-access memory that uses latching circuitry to store each bit.
• SRAM is volatile memory; data is lost when power is removed.
• The term static differentiates SRAM from DRAM which must be periodically refreshed.

Additional Information

• Dynamic random access memory (DRAM) is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function.
• Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level.
• EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage.

The correct answer is Versatility.

Key Points

• Versatility
  • It refers to the capacity of the computer of performing more than one task at the same time with the same accuracy and efficiency.
  • Versatility means the capacity to perform different types of work completely.

Additional Information

• Automation
  • The computer performs all the tasks automatically, without manual intervention.
• Speed
  • A computer works with much higher speed and accuracy compared to humans while performing mathematical calculations.
  • The time taken by computers for their operations is microseconds and nanoseconds.
• Diligence
  • A computer can perform millions of tasks or calculations with the same consistency and accuracy.
  • Its memory also makes it superior to that of human beings.
• Memory
  A computer has built-in memory called primary memory where it stores data.
  • Secondary storage are removable devices such as CDs, pen drives, etc., which are also used to store data.
• Reliability
  A computer is reliable as it gives consistent results for a similar set of data.

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.
