NUMBER CONVERSION

NUMBER SYSTEM CONVERSION -  October 07, 2020 NUMBER BASE CONVERSION                     In our previous section, we learned different types of number systems such as binary, decimal, octal, and hexadecimal. In this part of the tutorial, we will learn how we can change a number from one number system to another number system. As, we have four types of number systems so each one can be converted into the remaining three systems. There are the following conversions possible in Number System Binary to other Number Systems. Decimal to other Number Systems. Octal to other Number Systems. Hexadecimal to other Number Systems.                                                                                           ...

Classification of ipv4

Image
IPv4 - Address Classes Internet Protocol hierarchy contains several classes of IP Addresses to be used efficiently in various situations as per the requirement of hosts per network. Broadly, the IPv4 Addressing system is divided into five classes of IP Addresses. All the five classes are identified by the first octet of IP Address. Internet Corporation for Assigned Names and Numbers is responsible for assigning IP addresses. The first octet referred here is the left most of all. The octets numbered as follows depicting dotted decimal notation of IP Address − The number of networks and the number of hosts per class can be derived by this formula − When calculating hosts' IP addresses, 2 IP addresses are decreased because they cannot be assigned to hosts, i.e. the first IP of a network is network number and the last IP is reserved for Broadcast IP. Class A Address The first bit of the first octet is always set to 0 (zero). Thus the first octet ranges from 1 – 127, i.e. Class A addres...

Evolution Of Cellular Networks

Image
Evolution of cellular networks Mobile connectivity has evolved from being the infrastructure for human communication to telemetry, machine-to-machine and the internet of things applications. The mobile technology evolution from 1G to 4G and 5G The first version of mobile connectivity – 1G – introduced wireless voice. In 2G, roaming and SMS messaging were introduced and were later enhanced with GPRS for data communication. SMS messaging and GPRS became widely used for basic telemetry. Roaming made mobile technology suitable for deployments in multiple countries. Telenor was one of the first operators to offer M2M communications with things connected over the 2G network as early as the 1990s. 3G became a truly global standard and combined the best of competing technologies in a single standard. 3G evolutions were mainly centered around high speed data applications. 4G introduced LTE technology used for devices constantly connected to the internet. 4G answered the consumer need for bandwi...
