Fundamentals of Computer Class 6 MCQ with Answers and Explanations:
(1) Computer is an ………………………………………… machine.
(a) Water b) Electronic c) Battery d) None of these
Explanation :- Computer is a machine that only works on electricity. Computer can smoothly function only if there is proper supply or flow of electricity. The working of the computer can be stopped/ will not function where the power supply is disturbed/interrupted.
(2) The physical components of the computer are known as
(a) Software b) Program c) Hardware d) Both A and C
Explanation :- Hardwares are the important parts of the computer that are connected to the computer. With the help of hardwares we can make softwares to run on the computer properly. The hardwares are the things/objects that we can see, touch. Hardwares can be divided into input and output devices. Mouse, Keyboard, Monitor, CPU, etc are some examples of the harwares.
(3) It is the collection of raw facts that is un organized
(a) Instructions b) Data c) Information d) Processing
Explanation :- Data is the raw fact that is unprocessed and un organized. It includes words, numbers, images or sounds. On the basis of the raw data collected, Information can be generation by manipulating and processing the data.
(4) The data that is changing into the information is called as
(a) Processing b) Input c) Output d) None of the above
Explanation :- The data is feeded/ entered into the computer by making use of input devices. Then the data is been sent to the CPU for the processing process and with the help of the output devices the processed data is been displayed as the desired information. Processing means changing of the data into the information on the basis of the instructions provided. The processor inside the CPU perform the action of processing of data into the information.
(5) The data or instructions that is feeded into the computer
(a) Output b) Processing c) Storing d) Input
Explanation :-The first step is the data or instruction/command is entered into the computer with the help of the input devices such as keyboard, mouse, scanner etc. This input devices are connected to the computer system.
(6) It is an input device, that looks like a type writer
(a) Scanner b) Mouse c) Keyboard d) Joystick
Explanation :- Keyboard is rectangular in shape, that looks like a manual typewriter. Keyboard has many buttons (Alphabets, Numbers, Special symbols, and function keys, commands ) called as Keys. These keys are used for entering any typed thing/matter into the computer system. There are approximately 105 total keys in the keyboard.Hence keyboard is an input device and is used to feed any information or instruction into the computer.
(7) This device looks similar to the xerox machine and used to enter pictures or photographs into the computer
(a) Scanner b) Mouse c) Keyboard d) Joystick
Explanation :- Scanner is the input device that is used to enter the images, documents, photographs, graphs etc directly into the computer in the form of scanning them.. This device looks very similar to the manual xerox machine. It is connected to the computer with the cables. Flat bed scanners and hand held scanners are mostly used.
(8) This input device is also known as Digicam
(a) Camcorder b) Mouse c) Digital camera d) None of these
Explanation :-Digital camera is made used to enter photographs into the computer by way of capturing or storing them electronically/digitally. The use of photographic films are been avoided here. Hence the another name for digital camera is Digi cam.
(9) The information printed on a paper is
(a) Softcopy b) Photo copy c) Xerox copy d) Hard copy
Explanation :- The information or the result that we get after processing of the entered data in computer, sometimes it happens that we want that information or result physically on the paper. So we can take the result/information on the paper and get it printed with the help of printer. We can get the printed copies/print outs in two forms that is colour /black and white prints. There are various types of printers that can be mostly used which are Laser printer, Ink jet printer, Dot-matrix printer etc.
(10) This printer makes use of laser technology for printing images and text on the paper
(a) Inkjet Printers b) Dot- matrix printer c) laser printerd) None of these
Explanation :- Inkjet printer is the mostly used printer. This type of printer uses laser technology that is sued to print text or imageson paper. This printer is most expensive and gives the best quality of print outs. The speed of this printer is measured in pages per minute (ppm).
(11) This output device looks like a television screen.
(a) Monitor b) CPU c) Printer d) Scanner
Explanation :-The processed information that is been displayed as an output/ result on the screen that looks like the television is to be termed as Monitor. The processed information that appears on the monitor screen is known as soft copy, and remains for the temporary period of time. Nowadays monitor can be referred/identified by many names such as screen, display, video screen, video display unit (VDU).
(12) It is the computer’s main permanent storage area
(a) Compact Disc b) Hard disc c) RAM d) All of the above
Explanation :-Hard disc contains of many inflexible circular platters that stores the data, instruction or information by using the magnetic particles. The hard drive or hard disc drive (HDD) acts as the computers important storage area. The hard drive is fixed inside the CPU cabinet box which is used to store documents and programs. We can store the data/ information into the computer hard disc upto 500 GB to 8 TB or more.
(13) CPU is known as the ……………………………. of the computer.
(a) Heart b) Kidney c) Brain d) Lungs
Explanation :- CPU stands for Central Processing Unit or the processor that is always fixed on the motherboard inside the CPU cabinet box is the device that processes the data in the computer. CPU also performs the operations of calculations, processes of data into the information. CPU gets the data feeded by the input devices and shows the information/ output by making use of the output devices. CPU controls the entire working/ operation of the computer system and hence is regarded as the brain of the computer.
(14) The unit in the CPU that performs the mathematical problems
(a) Input unit b) Control unit c) ALU d) Processing unit
Explanation :-CPU (Central Processing Unit) consists of three units which are CU (Control Unit), MU (Memory Unit) and ALU ( Arithmetic Logic Unit). The ALU (Arithmetic Logic Unit) performs the activity/operations of doing mathematical operations/sums such as addition, subtraction, division and multiplication.
(15) Flash drives are the another name for
(a) Memory cards b) Pen drives c) Hard drive d) Compact disc
Explanation :- This is the modern storage device that is used for storing information/ data. This is a portable storage device and is connected to the Universal Serial Bus (USB) port of the computer or laptop. This device is light weighted too. This device has the storage capability of 512 MB to 100 GB. Pen drive is sued for transferring the data at a very high speed.
