Correct Answer :   Indian Statistical Institute, Calcutta(Kolkata)

---

A British-built HEC 2M computer, happened to be the first digital computer in India, which was imported and installed in Indian Statistical Institute, Kolkata, during 1955.

Correct Answer :   10⁻⁹ m

---

Nanotechnology (sometimes shortened to “nanotech”) is the manipulation of matter on an atomic and molecular scale. Generally, nanotechnology works with materials, devices, and other structures with at least one dimension sized from 1 to 100 nanometres which is equal to 10⁻⁹ m.

Correct Answer :   FORTRAN

---

The first programming languages predate the modern computer. At first, the languages were codes. The first modern programming language was FORTRAN (1955), the “FORMULA TRANSLATOR”, invented by John Backus, then COBOL,(1959) the Common Business Oriented Language, was used. Then PASCAL and BASIC came into existence.

Correct Answer :   Tim Berners-Lee

---

Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW) in 1989, while working at CERN. The Web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world.

Correct Answer :   Data transfer rate

---

A CD-ROM drive, a device that can read information from a CD-ROM. CD-ROM players can be either internal, or external. There are a number of features that distinguish CD-ROM players, the most important of which is probably their speed or data transfer rate. CD-ROM players are generally classified as single-speed or some multiple of single-speed.

Correct Answer :   FAX

---

Value-added telecommunication services are telecommunications for which suppliers “add value” to the customer’s information by enhancing its form or content or by providing for its storage and retrieval. FAX is not considered to be a Value-added telecommunication service.

Correct Answer :   multiplication

---

The ‘AND’ gate in computers has basic application of multiplication. It has two or more inputs and one output. An ‘AND’ gate produces an output of 1 if all the inputs are 1 if any of the inputs is zero then it produces an output of zero.

Correct Answer :   1959 – 1964

---

The period 1953-1964 is generally taken to be the period of second generation computers. Sometimes, 1946-1958 is supposed to be the period of first generation computers. By 1948, the invention of the transistor greatly changed the computer's development. The transistor replaced the large, cumbersome vacuum tube in televisions, radios and computers. As a result, the size of electronic machinery has been shrinking ever since. From 1955 onwards transistors replaced vacuum tubes in computer designs, giving rise to the "second generation" of computers. A second generation computer, the IBM 1401, captured about one third of the world market. IBM installed more than ten thousand 1401s between 1960 and 1964.

Correct Answer :   Local Area Network

---

A local area network (LAN) is a collection of devices connected together in one physical location, such as a building, office, or home.

Correct Answer :   Random Access Memory

---

Random Access Memory (RAM) is a form of computer data storage. A random-access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order. In contrast, other data storage media read and write data only in a predetermined order.
