Explanation: <p>ENIAC(1946)</p> <p><strong>Inventor</strong>:&nbsp;JP Eckert and JW Mauchly (America)</p> <p><strong>Characteristics</strong>:&nbsp;</p> <ul> <li>It is a combination of twenty accumulators.</li> <li>First electronic digital computer.</li> </ul> <p><strong>Applications</strong>:</p> <p>Used for weather prediction, atomic energy calculation and other scientific uses.</p> <br> ENIAC - Electronic Numerical Integrator And Computer

Correct Option: B
Explanation: <p><strong>Special Purpose Computer</strong><br />Special purpose computers are those computers which are used to solve a single and dedicated types of problem. e.g. Automatic aircraft landing, multimedia computer, etc.</p> <p><strong>Quantum computer</strong> was first introduced by Richard Feynman. It uses quantum mechanical phenomena. It is the fastest computer imitating brain working.<br /><strong>Nano computer</strong> is a general team used to describe a computer smaller than a microcomputer, usually about the size of a credit card. e.g. Raspberry Pi which could be used in schools to teach science to children.<br /><strong>Pratyush</strong> India&rsquo;s fastest and first multi-petaflops (PF) supercomputer named Pratyush was unveiled at Pune based Indian Institute of Tropical Meteorology (IITM).<br />Pratyush has 6.8 PF computational power installed at two MoES Institutes. 4.0 Peta Flops HPC facility at IITM, Pune and 2.8 Peta Flops facility at NCMRWF, Noida. Pratyush is fourth fastest supercomputer in the world dedicated for weather and climate research.<br /><strong>Note</strong> PF is a measure of a computer&rsquo;s processing speed.</p>

Correct Option: A
Explanation: Analytical Engine

Correct Option: D
Explanation: Christoper Latham Sholes

Correct Option: B
Explanation: Steve Jobs

Correct Option: C
Explanation: Computer cannot perform thinking. <br> <p><strong>Functioning of a Computer</strong><br />Computer performs four basic functions which are as follows</p> <ul> <li><strong>Input:</strong> Information or data that is entered into a computer is called input. It sends data and instructions to the Central Processing Unit (CPU).</li> <li><strong>Processing:</strong> It is the sequence of actions taken on data to convert it into information which is meaningful to the user. It can be calculations, comparisons or decisions taken by the computer.</li> <li><strong>Output:</strong> It makes processed data available to the user. It is mainly used to display the desired result to the user as per input instructions.</li> <li><strong>Storage:</strong> It stores data and programs permanently. It is used to store information during the time of program execution and possible to get any type of information from it.</li> </ul>

Correct Option: A
Explanation: very fast and can store huge amount of data. <br> <a href="https://www.atnyla.com/tutorial/advantages-of-computer/6/397">Read More: Advantages of Computer </a> <br> <a href="https://www.atnyla.com/tutorial/applications-of-computer/6/838">Read More: Applications of computer</a>

Correct Option: D
Explanation: <p><strong>General Purpose Computer</strong><br />General purpose computers are those computers, which are used to solve variety of problems by changing the program or instructions. e.g. To make small database, calculations, accounting, etc.</p>
