Computer Awareness Mixed Quiz: Set 47

Flash memory is erased electrically, not by ultraviolet light, so this is not one of its features. Flash memory is a type of EEPROM (electrically erasable programmable read-only memory) that can erase and rewrite whole blocks at a time, which makes it fast.

Customer relationship management software keeps the record of every dealing with a customer or prospect, including contacts, enquiries, calls, complaints, campaigns and purchase history, and is divided into operational, analytical and collaborative CRM.

UNIX was designed from the start as a time-sharing system, so this statement is false. UNIX was developed at Bell Labs from 1969 by Ken Thompson and Dennis Ritchie.

This block of 128 code points holds the Devanagari consonants and independent vowels, the dependent vowel signs or matras, the virama, the nukta, the danda and double danda, and the Devanagari digits; characters added later sit in a separate Devanagari Extended block.

Of the sectors listed, only Power and Energy and Banking and Financial Services are among the critical sectors named by NCIIPC.

DigiLocker was launched in 2015 as part of the Digital India programme of the Ministry of Electronics and Information Technology, and it gives every citizen a cloud account linked to Aadhaar in which boards, universities and transport departments place verified certificates that are accepted on a par with the original…

x86 and MIPS assembly are low-level languages written for particular processor families, while Python and Java are high-level languages. An assembly language uses short mnemonics such as MOV, ADD and JMP that stand directly for a processor's machine instructions, so each family of processors has its own.

Abstraction presents only what the user needs, such as the accelerator and brake of a car, and keeps the internal working out of sight; in C++ it is obtained through abstract classes with pure virtual functions and in Java through interfaces and abstract classes.

CDMA is a channel access method that lets many mobile users share the same radio frequency band at the same time.

Robert Noyce, one of the inventors of the integrated circuit, and Gordon Moore, who gave the observation known as Moore's law that the number of transistors on a chip doubles about every two years, left an earlier firm and founded Intel in 1968.

At the common MP3 bit rate of 128 kilobits per second, one hour of music takes roughly 55 to 60 megabytes, so about 50 MB is the closest figure.

Boehm described the spiral model, in which the project moves outward through repeated loops and each loop performs four activities: determining objectives, risk analysis and resolution, development and testing, and planning the next loop.

Project Loon used high-altitude balloons to beam internet access to remote areas. Project Loon was developed by X, the research lab of Google's parent company Alphabet, and began trials in New Zealand in 2013.

The command ps, short for process status, prints a list of processes with their process identification numbers, the terminal they belong to, the processor time used and the command that started each one.

Public Key Infrastructure (PKI) is the system of keys and certificates that secures digital signatures and encrypted communication. PKI uses a pair of keys for each user: a public key that anyone can see and a private key kept secret.

The Apriori algorithm first finds the sets of items that appear together often enough to pass a support threshold, using the rule that any subset of a frequent set must itself be frequent, and then turns those frequent sets into rules measured by confidence.

Data mining applies statistical and machine learning techniques to large stores of data to find knowledge that was not asked for in advance: customer segments, associations between products bought together, trends over time and unusual cases that may be fraud.

The Advanced Encryption Standard is the Rijndael cipher, designed by the Belgian cryptographers Joan Daemen and Vincent Rijmen, which won an open competition and was adopted in 2001 in place of the ageing Data Encryption Standard.

The correct answer is A, C-DAC, Pune, the Centre for Development of Advanced Computing, which besides building India's PARAM series of supercomputers created the GIST range of Indian language technology, including the add-on card and software that let ordinary computers display and print Indian scripts, and the LEAP Office suite…

Both are enterprise resource planning packages distributed as open-source software, so the source code can be studied and modified, and both are deployed by small and medium firms that cannot meet the cost of a large proprietary suite; ERPNext is the Indian entry in the category.
