UP Board 2019 Class 10: Model Paper for Computer Science
UP Board Class 10th Computer Subject: Model papers are being provided here for a thorough revision. A computer is one of the most important subjects for class 10th students of UP. Therefore, students should prepare this as for sure. The practice paper is given here which is very useful for students of the UP Board of Examination, Class 10th.

The sample paper is especially being prepared for the students by the in-house experts. Practising these questions will hopefully give a positive result.

Model Paper 2019 Class 10 UP Board for Computer exam is mentioned below:

1. Which of the following is the name of the logic circuit that can add two binary digits?
(a) Half adder
(b) Full adder
(c) Parallel adder
(d) Serial adder

Ans (a) half adder; an adder is a digital circuit that performs addition of numbers. In many computers and other kinds of processors, adders are used not only in the arithmetic logic unit(s), but also in other parts of the processor, where they are used to calculate addresses, table indices, and similar operations. Although adders can be constructed for many numerical representations, such as binary coded decimal or excess-3, the most common adders operate on binary numbers.

2. The functioning of computers are divided into three categories namely _____, ________ and ________.
(a) Mainframe, Supercomputer and Minicomputer                
(b) Analog, Digital and Hybrid             
(c) Palmtop, PC and Desktop              
(d) Micro-computers, Digital and Hybrid

Ans (b) Analog, Digital and Hybrid
Analog data is of continuous nature and which is not discrete or separate. Such type of data includes temperature, pressure, speed weight, voltage, depth etc. These quantities are continuous and having an infinite variety of values.

Digital function refers to a digital computer that can be used to process numeric as well as non-numeric data. It can perform arithmetic operations like addition, subtraction, multiplication and division and also logical operations. Most of the computers available today are digital computers.

 A hybrid function refers to a combination of digital and analogue computers. It combines the best features of both types of computers, i-e. It has the speed of the analogue computer and the memory and accuracy of a digital computer. Hybrid computers are used mainly in specialized applications where both kinds of data need to be processed.   

3. What do you mean by a website?

Ans. A website is a set of related web pages served from a single web domain. A website is hosted on at least one web server, accessible via a network such as the Internet or a private local area network through an Internet address is known as a Uniform Resource Locator.

4. What is a web browser?

Ans. A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video or other pieces of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources.

5. Which device is used to access your computer by other computer or to talk over the phone?

Ans. A modem (modulator-demodulator) is a device that modulates an analogue carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used with any means of transmitting analogue signals, from light emitting diodes to radio.
