a. OCRExplanation: Though, these days, we can find scanners that can do all of these tasks, OCR, OMR and MICR are the different kinds of scanners based on their special capabilities. OCR are good at recognizing characters in scanned images, OMR are good to find marks made in specific location and MICR can precisely verify the signatures in scanned image by comparing it with the pre-stored samples. So, looking at the options, OCR better suits as correct .
b. Dot per sq. inchExplanation: Dot per inch is the linear measurement - how many dots are used to print one inch of straight line. Dot per square inch is two dimensional measurement that takes care of printer's capability to print horizontal as well as vertical lines. Dots printed per unit time has nothing to do with the quality, it better relates to the speed of printing. Because third option is not valid, the all of above option too is not correct anymore. Now in between these two options, most of the books andoffer 'dots per square inch' as the measurement of output quality. Because earlier printers had different number of dots used to print horizontally and vertically, we had to take note of dots per square inch. Modern printers have almost same resolution for vertical lines as well as horizontal lines. So dots per square inch is somewhat obsolete. Now dots per inch (dpi) is enough to express printer quality. However, to be safe when both these two options are avialable, I choose 'dots per square inch' as correct answer (because the person who set question may take reference from those popular books or websites)
b. Input is never converted to digital formExplanation: Analog computers can accept real physical values such as speed, pressure, temperature etc as input and process them. They do not need to convert the input into digital form. It is only hybrid computers that accept input in analog and convert them into digital form to process. So first option is cancelled out. Input is never converted to digital form is pretty okay for analog computers. Output is displayed in digital form is quite unrelated to the question. Because the first option is already invalid, all of above option is no more suitable. So, Option B appears to be best suitable.
c. Both sequentially and parallelExplanation: In older computers, because the memory and storage devices were sequential, computers were compelled to use sequential only. But later on the newer methods in operating systems and direct access devicesand storage made it possible to process multiple instructions parallel. However, there are some data that are sequentially by nature such as audio, video etc which require sequential processing. So, in my opinion, option C, both sequentially and parallel is correct option.
c. J. Presper Eckert and John W MauchlyExplanation: John von Neumann introduced the Stored Program Concept which was fully used EDSAC. Joseph Marry Jacquard invented punched cards to automated his weaving loom. Joseph Presper Eckert and John William Mauchly had designed ENIAC which is considered as the first general purpose electronic computer. So, option C. is correct answer.
a. Dennis M. RitchieExplanation: Dennis M. Ritche invented the programming language called C. It is also important to remember that the C++ programming languages, an extension of C, that was developed by Bjarne Stroustrup in the early 1980s at Bell Laboratories. Niklaus Writh is wellknown for his programming language Pascal and Modula. Seymour Papert is one of the pioneers of artificial intelligence, as well as an inventor of the Logo programming language. Donald Knuth is the father of analysis of algorithms. So, the option A is correct answer for this question.
c. PeoplewareExplanation: Personnel who design software systems are system analysts, who programs are programmer, who operates are console-operators, who maintains are support personnel A term that collectively refer to these people is peopleware. Peopleware are the human involved in computer systems. So, option C is the correct answer.
d. 1991Explanation: The AIM alliance (Apple, IBM & Motorola) was an alliance formed on October 2, 1991, between Apple Inc. (then Apple Computer), IBM, and Motorola to create a new computing standard based on the PowerPC architecture. The stated goal of the alliance was to challenge the dominant Wintel computing platform with a new computer design and a next-generation operating system. It was thought that the CISC processors from Intel were an evolutionary dead-end in microprocessor design, and that since RISC was the future, the next few years were a period of great opportunity. So, I believe it was in 1991!
d. ComputerExplanation: Obviously Computers! Because the role of silica in computers - they are used to create microprocessors, ROM chips, RAM chips which made possible of today's computers, they are often called sillico sapiens!
d. GlitchExplanation: Glitch is another term to mean the error or problem in hardware or software. Leech, Squid and Slug has nothing to do in this context.
c. InfallibleExplanation: Throughout the development of computers they improved. They became faster, more powerful and cheaper. Modern computers are really cheaper in spite of their improved speed and power. However, they are not infallible. They are extremely reliable.
b. Reverse videoExplanation: Reverse video (or invert video or inverse video or 'reverse screen') is a computer display technique where the background and text color are inverted to highlight. So, reverse video is correct answer.
d. TaiwanExplanation: Please provide reference if you know any
b. MotherboardExplanation: Daughterboard are the expansion cards inserted in expansion slots in motherboard. Modems, sound cards, display adapters etc are some examples of daughterboards. There is no boards known as fatherboards and breadboards. Motherboard is the main circuit board on which a number of chips are mounted. So, Motherboard is correct answer.
a. MotherboardExplanation: Similar to explanation for Q. No. 14.
b. Which is assigned one and only one taskExplanation: A computer used by one person only is personal computer. A computer assigned for only one task is dedicated computer. For example, dedicated web server, dedicated print server etc. A computer that uses only one kind of software is embedded device (computer). All computers are meant for application software. So, in my opinion, option B is correct answer.
d. ModemExplanation: System unit refers to the CPU box. It contains a motherboard and CPU, disk controllers, different kind of interfaces are mounted in it. From among the given options, modem comes as separate device (whether internal or external modem). So, system unit do not contain modem.
c. CompilerExplanation: Interpreter translates each statement of high level program into machine code in turn and executes. Simulator creates real world situation so that the different experiments are possible. Computer games uses simulation extensively. Compiler translates high level program into machine codes all at once and creates an executable file. I don't think commander is related to the question in any respect. Thus, option C is correct answer.
a. InterpreterExplanation: The language processor that translate each instruction of high level program into machine instructions is Interpreter. Other explanation is similar to Q. 18.
d. SensorExplanation: Computers are not called intelligent machines. They are the slaves in a box. Microcomputers are not called intelligent. Programmable devices are not intelligent. If they were intelligent, computers too are programmable devices. Any device that contains sensor can input data and according to the change in situation, so these devices are called intelligent. Thus, option d is correct answer.
