Question Discussion & Solution

The correct answer is Motherboard.

Key Points

• The motherboard allows communication to and between the CPU, RAM, and all other computer hardware components.
• A motherboard (also called mainboard, main circuit board, system board, baseboard, planar board, logic board, or mobo) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems.
• It holds and allows communication between many crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. 

Additional Information

• Application software is a type of computer program that performs a specific personal, educational, and business function.
• System software is a type of computer program that is designed to run a computer's hardware and application programs.
• A central processing unit (CPU), also called a central processor, main processor, or just processor is the electronic circuitry that executes instructions comprising a computer program.

The correct answer is cell.

Key Points

• The basic unit of an Excel spreadsheet where we enter data is known as a cell.
• Every worksheet is composed up of thousands of rectangles, which are called cells.
• A cell is the intersection of a row and a column.

Additional Information

• Columns are recognized by letters (A, B, C), while rows are identified by numbers (1, 2, 3).
• Each cell has its own name or cell address rooted on its column and row.
• The cell address will also embark in the Name box.

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 Arithmetic Logic Unit.

Key Points

•  Register
  • A register is a quickly accessible location available to a computer's processor.
  • Registers usually consist of a small amount of fast storage.
  • Some registers have specific hardware functions and may be read-only or write-only.
• ​Arithmetic Logic Unit.
  • Arithmetic Logic Unit is a combinational digital circuit.
  • It performs arithmetic and bitwise operations on integer binary numbers.
  • ALU can be designed to perform complex functions.

Additional Information

• Central processing unit
  • It is the main processor or it is electronic circuitry that executes instructions comprising a computer program.
  • The CPU performs basic arithmetic logic, controlling, and input/output operations specified by the instructions in the program.
  • The individual physical CPU processor cores can also be multithreaded to create additional virtual or logical CPUs.
• Control Unit
  • The control unit is a component of a computer's central processing unit that directs the operation of the processor.
  • It tells the computer's memory, arithmetic logic unit.
  • The control unit may include a binary counter to tell the control unit's logic what step it should do.
• Memory unit
  • A memory unit is a component of a computer system.
  • It is used to store data, instruction and information.
  • It is also known as a main/primary/internal memory.
  • There are two types of memory-:
    1. Read only memory.
    2. Random-access memory.

The correct answer is Baidu.

Key Points

• BAIDU:
  • Baidu search engine is the Chinese search engine developed by Baidu Inc in the year 2000.
  • According to the Alexa Internet rankings, Baidu is currently the fourth largest website.
  • Services provided by the search engine - Baidu Baike (online encyclopedia), Baidu Wangpan (cloud storage services), Baidu Tieba (keyword-based discussion forum).
  • It has been blocked by the government in India in 2020.

Additional Information

• PACKETS:
  • Donald Davies gave this term in the year 1965.
  • The word 'packet' in computer terminology refers to a segment of data sent from one computer or device to another over a network.
  • A packet contains some important information like - source, destination, data, size, etc.
• COOKIES:
  • The web-browser programmer, Lou Montulli gave the term 'cookie'.
  • The text files containing data like username and password, that identify a computer over a network are known as 'cookies'.
  • HTTP cookies are a specific type of cookies stored on the user's computer and used to identify specific users by the web browser while browsing a website, thus improving the web browsing experience.
  • Cookies remember information and record the browsing activity of the user.
