The computers that we use are digital whereas we live in an analog world which means that we have to translate analog data into digital data. What is the name of the circuit which helps us in this conversion?
A)
D/A converter
B)
A/D converter
C)
Adapter
D)
Voice recognition

Correct Answer :   A/D converter

An analog-to-digital converter, or ADC as it is more commonly called, is a device that converts analog signals into digital signals. Analog information is transmitted by modulating a continuous transmission signal by amplifying a signal's strength or varying its frequency to add or take away data.

Which was the first computer to use transistors instead of vacuum tubes?
A)
Burroughs E-101
B)
Intel-650
C)
IBM-1401
D)
Datamatic-1000

Correct Answer :   IBM-1401

IBM- 1401 was the first computer to use transistor instead of vacuum tubes.
 
A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky, and were unreliable. A second generation of computers, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third-generation machines.
 
Because the transistor was so much smaller and consumed significantly less power, a computer system built with transistors was also much smaller, faster, and more efficient than a computer system built with vacuum tubes.

The punched card used in the IBM System/3 contains
A)
80 columns
B)
96 columns
C)
120 columns
D)
126 columns

Correct Answer :   96 columns

In the late 1960s, IBM introduced a new, smaller, round-hole, 96-column card format along with the IBM System/3 computer. These cards have tiny (1 mm), circular holes, smaller than those in paper tape. Data is stored in 6-bit BCD, with three rows of 32 characters each, or 8-bit EBCDIC.

A)
anthropomorphism
B)
artificial intelligence
C)
cybernetics
D)
cybernation

Correct Answer :   anthropomorphism

Anthropomorphism is the attribution of human traits, emotions, or intentions to non-human entities. ... Personification is the related attribution of human form and characteristics to abstract concepts such as nations, emotions, and natural forces, such as seasons and weather.

In negative logic, the logic state 1 corresponds to
A)
negative voltage
B)
zero voltage
C)
lower voltage level
D)
more negative voltage

Correct Answer :   lower voltage level

The zero output in the digital system does not mean negative, zero or more negative voltage. The 0 output indicates that the output is lower than the input then the input may be whatever.Therefore, in negative logic, the logic state 1 corresponds to the output 1 with lower voltage level.
