   The OSI model is a layered framework for the design of network systems that design allows for communication across all types of computer systems. It consists of seven separate but related layers, each of which defines a segment of the process of moving information across a network. Understanding the fundamentals of the OSI model provides a solid basis for the exploration of data communication. Layered Architecture build of seven ordered layers physical layer data link layer network layer  transport layer session layer presentation layer application layer As the message transfer from one device to another device, it may pass through many intermediate nodes. These intermediate nodes usually involve only the 1st three layers of OSI models. In developing the model, the designers distilled the process of transmitting data down to its most fundamental elements. They identified which networking function had related users and collected functions into discrete groups that becam...

Those threats pop-ups may be irritating, but they're there to ensure your computer can stop, and counterbalance malware warnings. Imagine you’re relaxing at your computer, catching up with the news, when a little box pops up on your screen. It’s a safety warning, also, possibilities are, you merely click out of it without a second thought.   But could neglecting these signs be putting your computer or your private data in danger? Hackers can cause a lot of trouble with even the smallest amount of private information. Here is everything a hacker can do with just your email address. Why they’re very easy to ignore? Pop-ups notifications are a big annoyance. Continue to the point that you have little or no idea what those updates and threats really intend, and it makes it intriguing to neglect them. Except it’s one of the obvious signs you’re about to be hacked. It’s difficult to take them seriously. Director at Kumo Digital, Mathew Porter describes the three kinds of warnings you’...

Rational agent approaches Artificial intelligence is defined as the study of a relational agent. A rational agent could be anything that makes decisions like a person, firm, machine, or software. It acts with the best outcome percept. (agents perceptual inputs at a given instance) An AI system is composed of an agent and its environment. The environment may contain other agents. An agent is anything that can be viewed as : Perceiving its environment through sensors and Acting upon that environment through actuators. Note Every agent can perceive its own actions(but not always the effects) It will run in cycles of perceiving, thinking, and acting. Take humans for eg, we perceive our environment through our five senses (sensors), we think about it, and then act using our body parts (actuators). Similarly, robotic agents perceive the environment through sensors that we provide them it can the camera, microphones, infrared detectors. They do some computing(thinking) and...
