Question Discussion & Solution

The correct answer is Spreadsheet.

Important Points

• MS Excel, a worksheet, also known as a Spreadsheet, is a table into which you enter data and data label.
• Worksheet used in Excel documents is a collection of cells organized in rows and columns. It is the working surface you interact with to enter data.
• Each worksheet contains 1048576 rows and 16384 columns and serves as a giant table that allows you to organize information.
• Typically, a workbook contains several worksheets with related content and only one of the worksheets is active at a time.

Key Points

• The main characteristics of worksheets:
  • Cells: Each worksheet has a significant number of cells that can be assigned values and various formatting options.
  • Rows and Columns: Cells in a worksheet are organized into rows and columns. The API of a worksheet allows you to insert, manipulate and delete rows and columns.
  • Names (Named Ranges): The Worksheet class exposes a Names property of type NameCollection that allows you to create, update and manage names.
  • Collection of Hyperlinks: Each worksheet can contain numerous hyperlinks to web pages, particular cells in the workbook, or email addresses.
  • Find and Replace: You can easily find and replace text and numbers in the content of a worksheet.
  • Protection: You can restrict the user from modifying the content and structure of the worksheet.

Additional Information

The correct answer is ROM.

Key Points

• Each memory cell of a ROM chip has either a transistor for a 1 bit or none for a 0 bit.
• ROMs(Read-only memory) is used for programs that are essential parts of a computer’s operation, such as the bootstrap program that starts a computer and loads its operating system or the BIOS (basic input/output system) that addresses external devices in a personal computer (PC). 
• EPROM (erasable programmable ROM), EAROM (electrically alterable ROM), and flash memory are types of nonvolatile memories that are rewritable, though the rewriting is far more time-consuming than reading.
• They are thus used as special-purpose memories where writing is seldom necessary—if used for the BIOS, for example, they may be changed to correct errors or update features.

Additional Information

• Cache memory:
  • Cache memory, also called Cache, a supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processor of a computer.
  • The cache augments and is an extension of, a computer’s main memory.
  • Both main memory and cache are internal, random-access memories (RAMs) that use semiconductor-based transistor circuits.
  • The cache holds a copy of only the most frequently used information or program codes stored in the main memory; the smaller capacity of the cache reduces the time required to locate data within it and provide it to the computer for processing. 
• RAM:
  • RAM, in full random-access memory, Computer main memory in which specific contents can be accessed (read or written) directly by the CPU in a very short time regardless of the sequence (and hence location) in which they were recorded.
  • Two types of memory are possible with random-access circuits, static RAM (SRAM) and dynamic RAM (DRAM).
  • A single memory chip is made up of several million memory cells.
  • In an SRAM chip, each memory cell stores a binary digit (1 or 0) for as long as power is supplied.
  • In a DRAM chip, the charge on individual memory cells must be refreshed periodically in order to retain data.
  • Because it has fewer components, DRAM requires less chip area than SRAM; hence a DRAM chip can hold more memory, though its access time is slower.

The correct answer is Margins.

Key Points

• A margin is a space separating text or other elements from the edge of the paper commonly adjusted through the page setup.
• Most programs allow for the top, bottom, left, and right margins to be set. 
• By increasing the size of the margins, you decrease the available space on the page that text can occupy.
• In other words, a page with bigger margins has less room for text.
• If you decrease the size of the margins, the page can accept more text.

Additional Information

• Justify is a text that is both left-aligned and right-aligned. 
  • In Microsoft Word, you can use the Ctrl + J keyboard shortcut to justify any text.
• A trapdoor is a concealed means of bypassing security to gain access to a restricted part of a computer system.
  • For example, a programmer may insert a piece of code that would allow them access to a computer or secure area using a password that only they know.

The correct answer is Microprocessor.

Key Points

• Pentium microprocessors developed by Intel Corp.
• Pentium introduced in 1993 as the successor to Intel’s 80486 microprocessor.
• Pentium is a series of x86 architecture-compatible microprocessors 
• It using CISC (complex instruction set computer) architecture, its main features were a 32-bit address bus, a 64-bit data bus, a built-in floating-point, and memory-management units, and two 8KB caches.
• It was available with processor speeds ranging from 60 megahertz (MHz) to 200 MHz.
• Pentium was superseded by ever faster and more powerful processors,
  • Pentium Pro (1995),
  • Pentium II (1997),
  • Pentium III (1999),
  • Pentium 4 (2000), and
  • Pentium 4 Dual Cores (2005).
• Pentium chips were the most widely used CPUs in the world for general-purpose computing.
• Various Pentium 4 models are used in entry-level PCs and other devices.

Additional Information

The correct answer is PayTm.

• Facebook is an American social media platform.
• Products owned by Facebook are. Instagram, Messenger, WhatsApp, Oculus VR.
• Facebook acquired Instagram in 2012.
• Instagram was founded by Kevin Systrom and Mike Krieger
• Twitter is an American social networking service provider.
  • Parent company: Odeo.​
  • Twitter was founded by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams
• Paytm is an Indian multinational technology company that specializes in digital payment systems.
  • Hence PayTm is the answer.
