প্রশ্নঃ which of the following TCP/IP addresses constitute the loopback address?
বর্ণনাঃ TCP/IP networks specify a loopback that allows client software to communicate with server software on the same computer. users can specify an IP address, usually 127.0. 0.1, which will point back to the computer's TCP/IP network configuration. The range of addresses for loopback functionality is the range of 127.0.

Landslides cause tsunamis when the debris falls into the water.
প্রশ্নঃ which of the following metals is known to pollute the air of big cities with a large number of vehicles?
বর্ণনাঃ Lead pollutes the air of a big city. Lead (Pb) is a metal found naturally in the environment as well as in manufactured products. The major sources of lead emissions have historically been from fuels in on-road motor vehicles (such as cars and trucks) and industrial sources.
প্রশ্নঃ The fraction of solar energy reflected from Earth into space is known as
বর্ণনাঃ Albedo is the fraction of solar energy (shortwave radiation) reflected from the Earth back into space. It is a measure of the reflectivity of the earth's surface. Ice, especially with snow on top of it, has a high albedo: most sunlight hitting the surface bounces back towards space. Insolation is the incident solar radiation onto some object. Specifically, it is a measure of the solar energy that is incident on a specified area over a set period of time. Generally, insolation is expressed in two ways.

প্রশ্নঃ Find the out put of the following Java code line: System.out.printIn(math.floor(-7.4))
বর্ণনাঃ Floor is a function in java which returns the lower limit. Here -8 is lower limit to -7.4 and the higher limit would be -7. If you represent these numbers on the number line you would have -7 approaching towards zero and -8 away from 7.4 and far from zero so the lower limit would be -8. Hence the answer is -8.

প্রশ্নঃ what is the time complexity of Huffman Coding?
বর্ণনাঃ The time complexity of the Huffman algorithm is O(nlogn). Using a heap to store the weight of each tree, each iteration requires O(logn) time to determine the cheapest weight and insert the new weight. There are O(n) iterations, one for each item.
প্রশ্নঃ Which sever can you use to dynamically assign IP addresses to the PC s in a LAN?
বর্ণনাঃ DHCP is an abbreviation for Dynamic Host Configuration Protocol. It is an application layer protocol used by hosts for obtaining network setup information. The DHCP is controlled by DHCP server that dynamically distributes network configuration parameters such as IP addresses, subnet mask and gateway address.
