Key Points

• Digital computer, any of a class of devices capable of solving problems by processing information in discrete form.
  • It operates on data, including magnitudes, letters, and symbols, that are expressed in binary code—i.e., using only the two digits 0 and 1.
  • Examples of digital electronic computers include the IBM PC, the Apple Macintosh as well as modern smartphones.
• Today computers are being used almost everywhere like schools, colleges, hospitals, offices, railway stations, hotels, etc.
• A computer system is multitasking so that you can do two tasks very easily at the same time.

Additional Information

• Storage Capacity of Computer
  • Computer systems have a very large capacity to store any type of data.
  • A computer can store and resell any information due to its storage capacity. 
  • Computers have the ability to store all types of data such as data, pictures, files, programs, games, and sound for many years and later we can get any data in a few seconds at any time for taking that information and for future retrieval.
• Reliability of Computer
  • Reliability is a very big characteristic of computers.
  • Today almost all the big industries or big e-Commerce companies like Amazon and Flipkart, and big search engine companies like - Google and Bing, all these companies are dependent on computers. 
  • Today every major industry and company in the world has full confidence in their computers, and their entire business is running from computers.

The code for ‘IRONIC’ would be ‘#!?@#&’.

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.
