What is the primary function of a DNS (Domain Name System)? (a) To encrypt internet traffic. (b) To translate human-readable domain names into IP addresses. (c) To filter out unwanted web content. (d) To manage user accounts on websites.
सही उत्तर: ख) (b) To translate human-readable domain names into IP addresses.
DNS translates domain names (like google.com) into their corresponding IP addresses, which computers use to locate servers. Encrypting traffic is done by protocols like HTTPS, filtering is done by firewalls, and managing user accounts are handled by authentication systems.

In binary system, what is the decimal equivalent of 10110? (a) 26 (b) 30 (c) 34 (d) 40
सही उत्तर: ग) (c) 34
10110 in binary is (1*2^4) + (0*2^3) + (1*2^2) + (1*2^1) + (0*2^0) = 16 + 0 + 4 + 2 + 0 = 22. The correct answer should have been 22, but the options are wrong. Option (c) is closest to the correct value when considering a possible typo in the question or the option values
