What is General Packet Radio Service (GPRS)?
Networking , Technology & Science / July 14, 2018

GSM was the most successful second generation cellular technology, but the need for higher data rates spawned new developments to enable data to be transferred at much higher rates. The General Packet Radio Service (GPRS) is an enhancement to the existing GSM network infrastructure and provides a connectionless packet data service. The same cellular base-stations that support voice calls are used to support GPRS and as a consequence GPRS can be used wherever it is possible to make a voice call. GPRS roaming agreements exist with a large number of countries and this means users can use GPRS devices whilst abroad. GPRS is based on internet Protocols (IP) and enables users to utilize a wide range of applications – email and internet and/or intranet resources for instance. With throughput rates of up to 40 Kbit/s, users have a similar access speed to a dial-up modem, but with the convenience of being able to connect from anywhere. Basic Overview of GPRS GPRS (General Packet Radio Service) is a service within the GSM network, just like the two most popular services SMS and voice connections. GPRS is used for transmitting data in the GSM network in from of packets. The connection to…

What is Packet Sniffing in Networking?
Networking , Technology & Science / July 13, 2018

Packets in computer communications can be defined as a quantity of data of limited size. In Internet all traffic travels in the form of packets, the entire file downloads, Web page retrievals, email, all these Internet communications always occur in the form of packets. In the internet, packet is a formatted unit of data carried by a packet mode in computer network Packets are the base of all data sent on the internet, yet they are often used insecurely. Tampering with live packets and the process it takes in order to alter packets traveling along the network are getting easier. Packet sniffing is commonly described as monitoring packets as they go across a network. Packet sniffers are typically software based, but can be hardware pieces installed directly along the network. Sniffers can go beyond network hosts that are seen in local area networks (LAN) that only handle data that is sent specifically to them. Basics Overview of Packet Sniffing Packet sniffing is the act of capturing packets of data flowing across a computer network. The software or device used to do this is called a packet sniffer. Packet sniffing is to computer networks what wiretapping is to a telephone network. …

What is Machine Learning & why it is important?
Technology & Science / July 7, 2018

Machine Learning (ML) is new age computing technology. It was born from pattern recognition and theory of computers. It can learn without being programmed to perform specific tasks. Researchers interested in artificial intelligence want to see if computers could learn from data. The iterative aspect of machine learning is important because as models are exposed to new data, they are able to independently adapt. They learn from previous computations to produce reliable, repeatable decisions and results. It’s a science that’s not new – but one that has gained fresh momentum. Machine learning is domain of engineering where algorithms and computer based programs are learnt from data and past experience and provides decisions and analysis based on their experience and learned knowledge. Machine Learning: Basic description Machine learning is a set of tools that, broadly speaking, allow us to “teach” computers how to perform tasks by providing examples of how they should be done. For example, suppose we wish to write a program to distinguish between valid email messages and unwanted spam. Machine learning is one of the fastest growing areas of computer science, with far-reaching applications. Machine learning is programming computers to optimize a performance criterion using example data or past experience. We need…
