ISCII was adopted by the Bureau of Indian Standards as IS 13194 in 1991; it is an 8-bit code whose lower 128 positions are the same as ASCII and whose upper 128 positions carry an Indian script, a single table serving ten scripts because they share the phonetic order inherited…

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.

The correct answer is A, the Unicode Consortium, a non-profit body of software companies, governments and individual experts that publishes the Unicode Standard, assigns code points to characters and releases a new version with new scripts and symbols from time to time.

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.

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.

Salesforce is the best-known customer relationship management product delivered as a cloud service, used over a browser on subscription, with Zoho from India and Microsoft Dynamics 365 among the other names in the category.

Online analytical processing answers few but complex queries that aggregate, slice and compare historical data held in a data warehouse, which is what business intelligence dashboards and drill-down reports rest on.

A contra voucher records movements that do not change the total funds of the business but only shift them between cash and bank or between two bank accounts, which is why both sides of the entry are the firm's own accounts.

After a company is created or selected, the user reaches the Gateway of Tally, from which the masters, vouchers, reports and utilities are opened; it is the screen named in question papers because every later action starts there.

A decision support system is interactive and model-based: it holds data, models and a user interface so that a manager can change assumptions, run alternatives and compare outcomes on problems that are neither wholly routine nor wholly open-ended, such as pricing a product, choosing a warehouse site or planning a…

All three are sold as enterprise resource planning suites, with modules for finance, human resources, materials, manufacturing and sales working on one shared database; Infor belongs to the same list, and Odoo and the Indian ERPNext are the open-source examples.

A TPS serves the operational level, capturing sales, deposits, bookings, issues of material and payroll entries as they happen, where accuracy, speed and reliability matter more than analysis; it is also the source of the data that higher systems later summarise.

Tally, from Tally Solutions of Bengaluru, keeps ledgers and groups, takes entries as vouchers, and produces the trial balance, profit and loss account, balance sheet, day book and stock summary without separate work; later versions added inventory, payroll and tax features, and the current line is TallyPrime.

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.

An ERP package replaces separate departmental programs with one integrated suite built on a single shared database, so a transaction entered once flows through stock, production, dispatch and the ledger.

Private is the most restricted access specifier and is also the default for a C++ class, so private data members can be read or changed only by the member functions of that class, and by a friend function or friend class if one is declared.

Java deliberately leaves out multiple inheritance of classes to avoid the ambiguity that arises when two base classes supply a member of the same name, the problem often called the diamond problem, and it provides interfaces so that a class can still take behaviour from more than one source.

A constructor carries the same name as its class, is called automatically the moment an object is created and is normally used to give the data members their initial values; it returns no value at all, not even void, and it can be overloaded.

Inheritance lets a derived, child or sub class take the members of a base, parent or super class and add its own, which is the main route to code reuse in object-oriented programming; its forms are single, multiple, multilevel, hierarchical and hybrid.

A class only describes the data members and member functions that its objects will have, while an object is created from the class, occupies memory and holds actual values; one class may have any number of objects.
