Question Discussion & Solution

The correct answer is Accumulator.

Key Points

• An accumulator is a type of register present in a CPU (Central Processing Unit).
• It works as a temporary storage location that keeps an intermediate value in logical and mathematical calculations.
• Intermediate results of execution are progressively stored in the accumulator, replacing the previous value.

Additional Information

• An IR (Instruction Register) saves machine instruction that is currently under execution. It is a register that sits at the top of the memory hierarchy. A variety of registers fulfills different operations in a central processing unit (CPU) – the function of the IR is to keep that currently stacked instruction for use.
• A PC (program counter) is a CPU register that has the address stored for the next instruction to be processed from memory. It is a digital counter required for quicker execution of tasks as well as to keep track of the current execution point. 
• The MAR (Memory Address Register) is the register in the control unit that holds the address of a register to receive or store from or to the storage. The Memory Address Register is half of an interaction between a microprogram and storage.

The correct answer is Software program.

• An operating system is system software that manages computer hardware, software resources, and provides common services for computer programs. Operating systems are found on many devices such as a computer, mobile phones, video games etc.
• Software program
  • It is a set of instructions, or a set of modules or procedures, through which computer operation is performed.
  • It is often called a software application and a software product.

Additional Information

• Computer system
  • A Computer system is usually defined as a combination of both hardware and software working together.
  • Hardware is the physical components of a computer and software is the programs that run on a computer.
• Network
  • It is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data.
  • E.g - The Internet, often referred to as the ‘Net’, consists of a complex network of computers connected by high-speed communication technologies like satellites, microwave devices, etc.
• Hardware device
  • Computer hardware includes the physical parts of a computer, such as a case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.
  • It accepts the data (input) from the user.
  • The computer has memory chips, which are designed to hold data until it is needed.
  • It processes this data into information. The computer has an electronic brain called the Central Processing Unit, which is responsible for processing all data into information according to the instructions given to the computer.
  • It then returns the processed information (output) to the user.

Option - 1 - Stream - A stream is a body of water with surface water flowing within the bed and banks of a channel.

Option - 2 - Canal - Canals are waterways channels, or artificial waterways, for water conveyance, or to service water transport vehicles.

Option - 3 - Brook - A small stream.

Option - 4 - Bridge - A bridge is a structure built to span a physical obstacle, such as a body of water, valley, or road, without closing the way underneath.

All except bridge contain water.

Hence, option 4 completes the pattern in question figure.
