Q1What is the decimal value of the binary number 1011?
To convert 1011 from binary to decimal, multiply each bit by its place value: 8, 4, 2 and 1. The sum is 8 + 0 + 2 + 1 = 11.
Q2In a positional number system, what is the base of the binary number system used for internal representation in digital computers?
The binary number system has only two possible digits: 0 and 1. Therefore each place value is a power of 2, making 2 the base of the system.
Q3What is the decimal equivalent of the binary number (1011)2?
To convert 1011 from binary to decimal, multiply each bit by its positional value: 1x8 + 0x4 + 1x2 + 1x1. The sum is 11.
Q4Which number system uses only the symbols 0 and 1?
The binary number system is a base-2 positional system. Digital computers internally represent data using two states, conventionally written as 0 and 1.
Q5Which option correctly classifies a keyboard and a printer by their usual computer functions?
