Statement (I): Microprocessors which have memory and various input/output arrangements, all on the same chip, are called microcontrollers. Statement (II): The microcontroller is the integration of a microprocessor with RAM, ROM, EPROM, EEPROM and I/O interfaces, and other peripherals such as timers, on a single chip.

Statement (I): Microprocessors which have memory and various input/output arrangements, all on the same chip, are called microcontrollers. Statement (II): The microcontroller is the integration of a microprocessor with RAM, ROM, EPROM, EEPROM and I/O interfaces, and other peripherals such as timers, on a single chip. Correct Answer Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I). 

Concept:

Systems using microprocessors basically have three parts:

A central processing unit (CPU) to recognize and carry out program instructions (this is the part which uses the microprocessor),

Input and output interfaces to handle communications between the microprocessor and the outside world (the term port is used for the interface), and

Memory to hold the program instruction and data. Microprocessors which have memory and various input/output

Arrangements all on the same chip are called microcontrollers.

The microcontroller is the integration of a microprocessor with memory and input/output interfaces, and other peripherals such as times, on a single chip.

Consider the following statements: 1. RAM is a non-volatile memory whereas ROM is a volatile memory 2. RAM is a volatile memory whereas ROM is a non-volatile memory 3. Both RAM and ROM are volatile memories but in ROM data is not when power is switched off Which of the above statements are correct?
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. What inference can be drawn from the above?

The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: Chat bots and other interfaces are saving employees and HR heads time for more productive activities by providing information and replies to diverse queries or concerns. A few years ago, business communication was driven by multiple faxes in a day and emails were the only quick mode of exchanging information. This information went through the organisation's who's who, while the others were mostly engaged in the daily rut of redundant activities, preventing them from directing their capabilities towards more productive areas. Which of the following arguments brig out the idea that introduction of chat bots and other interfaces is not helping in boosting up the processes? Arguments: I. Using these conversational interfaces, HR departments are successfully aligning themselves with the swiftly-changing organisational processes. These platforms represent people friendly technologies that keep employee experience at the centre, continuously evolving with them.  II. HR technologies are increasingly using advanced machine learning for measuring and analysing workforce engagement. Sentiment analysis is a unique way of gauging an employee's disposition towards the organisation, providing valuable insights essential for improving productivity and predicting attrition rates.  III. The seamless experience chat bots provide makes employees focus on activities that require critical abilities and strategic thinking. Besides enabling HR processes such as generating leave applications and reimbursement forms, the use of chatbots provides quick and smooth access to data from anywhere, anytime.
