Can you imagine a fridge which checks its egg tray and reminds you to buy eggs in your mobile phone or orders the nearby grocery store to supply eggs to your home; an air conditioner that can be switched on or off using your mobile phone; or a car that automatically reminds you about filling fuel as you approach a fuel pump? This is being made possible using Internet of Things (IoT). IoT is the concept of connecting all devices like mobile phones, fridges, cars, air conditioners, lamps, wearable devices, etc. To the internet. Each device is provided with a unique IP address which identifies it allows it to transfer data over Internet without human intervention. The huge increase in the number of IP addresses due to the implementation of IPv6 supports the introduction of this technology. The IoT can be used to monitor health of patients and inform the doctor about an urgency, applied to things which helps us reduce wastage like power, water, etc. and improve the way we work and live   

The Global positioning system (GPS) is a network of 24 navigation satellites orbiting the Earth that people can use to pinpoint their position. The satellites orbit at a height of 20000 kilometer. A GPS receiver picks up signals from any of these satellites that are above the horizon. It uses information in each signal to work out how far away it is from satellites. it can calculate its position on the earth's surface when it has information from atleast three satellites. A basic GPS receiver shows the latitude and longitude of its position on its screen. More advanced receivers, especially those designed for use in vehicles, show their position on a digital map. These recevers often show extra  information, such as the vehicle's speed and the length of the journey. Some receivers warn drivers if they exceed the speed limit for a road and even tell drivers which traffic lane to use at next junction. Directions are shown on the screen and also spoken by a synthesized

  Most electric toasters not only grill slices of bread, they also pop them up when ready. While the slices rest on a spring-loaded rack, electric heating elements toast the bread. At the same time, a bimetallic strip heats and expands. One of the two metals in this strip expands more quickly than the other, causing the strip to curve. As it bends, it completes an electrical circuit and activates an electromagnet. The magnet attracts a catch, releasing the spring that holds the rack down in the toaster. The elements switch off, and the toasted slices pop up.  

Optical microscopes from a magnified image by using lenses to bend light. Some special purpose microscopes used in industry and research  are designed for observing particular material, such as living cells. They produce magnifications of up to about 2000. Electron microscopes produce magnifications of as much as 50 million, although 2 million is more typical. Their images are formed by means of electrons focused by magnetic lenses. There are two main types: scanning electron microscopes (SEMs) scan electrons back and forth across the surface of specimen; transmission electron microscopes (TEMs)  transmit electron through a thin slice of the specimen.

  Threats to computers and networks are a major issue as long as information is accessible and transferred across the Internet. Different defense and detection mechanisms are developed to deal with these attacks 1.FIREWALL A firewall is a system of computer hardware and software that provides security to the computer network in an organisation. A firewall controls the incoming and outgoing network traffic by analysing the data and determining whether they should be allowed through or not, based on a rule set. Firewalls deny malicious data from entering into the computer networks. 2.ANTI-VIRUS SCANNERS Viruses, worms and Trojan horses are all examples of malicious software (malware). Antivirus tools are used to detect them and cure the infected system. Anti-virus software scans files in the computer system for known viruses and removes them if found. The antivirus software uses virus definition file containing signatures (details) of viruses and other malware that are known. When an ant

  A Denial of service (DoS) attack is usually aimed at a web server. Such an attack forces the server/computer to restart. An attack in which the attacker's goal is to shut down the target server rather than stealing data is called DoS attacks. This prevents genuine users of a services/website on the web server from using that service. This attack can be done using a single computer called Denial of service (DoS) attack or using more than one computer called Distributed Denial of service (DDoS) attack. We have learned that when we type a website address in the browser and press the enter key, the browser requests for that web page from the server. DoS attacks sends large number of such requests to the server until it collapses under the load and stops functioning. A DoS attack using a computer on a network slows down the network by flooding a server with large number of requests. A DDoS attack uses multiple computers in the network that it has previously infected. These infected. T

 A computer network may span any account of geographical area. It can be on a table, in a room, in a building, in a city, in a country , across continents or around the world. On the basis of the area covered, computer networks are classified as: PAN - Personal Area Network  LAN - Local Area Network MAN - Metropolitan Area Network WAN - Wide Area Network PERSONAL AREA NETWORK PAN is a network of communicating devices (computer, mobile, tablet, printer, etc.) in the proximity of an individual. It can cover an area of a radius with few meters. When we transfer songs from one cell phone to another or from a PC to an MP3 player, a PAN is set between the two. PAN can be set up using guided media (USB) or unguided media (bluetooth, infrared) LOCAL AREA NETWORK LAN is a network of computing and communicating devices in a room, building, or campus. It can cover an area of radius with a few meters to few kilometers. A networked office building can contain a few small LANs (like some schools hav
