All the submitted appear to be belonging to the old technology/times (2 years back). Hence, it is highly unlikely to be asked again.
ISDN
Abbreviation of integrated services digital network, an international communications standardvideo, and data over digital telephone lines or normal telephone wires. It supports data transfer rates of 64 Kbps (64,000 bits per second).
This mode was very important and widely used for internet access and teleconferencing two years back. However, now-a-days broadband networks has taken over.

EPROM
It stands for Electrically Erasable Programmable Read-Only Memory, is a type of non-volatile memory used in computers and other electronic devices to store small amounts of data that must be saved when power is removed, e.g., calibration tables or device configuration. for sending voice,
When larger amounts of static data are to be stored (such as in USB flash drives) a specific type of EEPROM such as flash memory is more economical than traditional EEPROM devices.
Developed by George Perlegos at Intel in 1983.

REER
It is the weighted average of a country's currency relative to an index or basket of other major currencies adjusted for the effects of inflation. The weights are determined by comparing the relative trade balances, in terms of one country's currency, with each other country within the index.This exchange rate is used to determine an individual country's currency value relative to the other major currencies in the index, as adjusted for the effects of inflation. All currencies within the said index are the major currencies being traded today: U.S. dollar, Japanese yen, euro, etc.
This is also the value that an individual consumer will pay for an imported good at the consumer level. This price will include any tariffs and transactions costs associated with importing the good.

CACP (India Year book gives detail information)
The Agricultural Prices Commission was set up in January, 1965 to advise the Government on price policy of major agricultural commodities with a view to evolving a balance and integrated price structure in the perspective of the overall needs of the economy and with due regard to the interests of the producer and the consumer. Since March 1985, the Commission has been known as Commission for Agricultural Costs and Prices.
The Commission is composed of a Chairman, a Member Secretary, two official members and three non-official members. The non-official members are representatives of the farming community. They are usually persons with long field experience and active association with the farming community.
Assurance of a remunerative and stable price environment is considered very important for increasing agricultural production and productivity since the market place for agricultural produce tends to be inherently unstable, which often inflict undue losses on the growers, even when they adopt the best available technology package and produce efficiently. Towards this end, minimum support prices (MSP) for major agricultural products are fixed by the government, each year, after taking into account the recommendations of the Commission for Agricultural Costs and Prices (CACP).
