subnet notation

A student asked me a question a few days ago, but I know little about the internet. So I asked my teacher, and I will get the answer today! IP :***.***.***.***Mask: 255.255.255.0It is divided into six subnets. How many computers can each subnet have? The answer is as follows: This question cannot be computed, because to divide subnets, it must be a power of 2 to n; otherwise, it cannot be divided. Some people say that this question is very diffic

Along with the gradual enlargement of the LAN scale, a network is divided into several different subnets, in order to realize the individualized management requirement according to the work requirements of different subnets. Considering that larger LANs typically use a DHCP server to assign IP addresses to each workstation, but once the LAN is divided into multiple subnets, do we have to create a DHCP server in each of the different subnets to provide IP address assignment services for workstati

Inverse Polish notation (Reverse Polish notation) Is a representation that places operators after the operands. For example, if 3× 4 is expressed in reverse Polish format, it should be written as 3×. In 1920, the Polish mathematician Jan ł ukasiewicz invented a mathematical notation. It places operators before all operands. This

A problem found during my internship was that the large floating point number was removed from the database and then changed to the scientific notation display. However, the original verification control did not recognize the scientific and technical methods, which made the data unable to be properly stored, A solution is found temporarily. When big data is input, the floating point type is displayed in scientific

in the previous three articles, we discussed asymptotic analysis , worst, average, and best algorithm cases . The main idea of asymptotic analysis is to measure the efficiency of an algorithm that does not depend on machine-specific constants, and do not need to perform algorithms and programs to compare the time. The asymptotic symbol is a mathematical tool used to represent the time complexity of an algorithm for asymptotic analysis.The following 3 asymptotic symbols are mainly used to repres
