 WIFI



Now a days usage of internet has increased a lot and still increasing must a very high rate.

 WIFI is aone of the most needful device across the globe with many features. Anyone can have an excess to it and a single WiFi can be used within a limited range for a number of pupils nearby. It lo provides very high speed connection.



First WiFi was used on August 11, 1942 by Hedy Kiesler Market.

World fastest WiFi speed is 91gb per second and it is 13,000 times faster than normal speed. It is available in NASA.


INCOME OF THE EMPLOYEES WORKING IN WIFI COMPANY


minimum starter package of normal software engineer is rs 10,000 and it rise up to Rs. 50,000 per month.


WIFI WORKING


Introduction


Wireless technology has widely spread lately and you can get connected almost anywhere; at home, at work, in libraries, schools, airports, hotels and even in some restaurants.

Wireless networking is known as WiFi or 802.11 networking as it covers the IEEE 802.11 technologies. The major advantage of WiFi is that it is compatible with almost every operating system, game device, and advanced printer. 

Working

Like mobile phones, a WiFi network makes use of radio waves to transmit information across a network. The computer should include a wireless adapter that will translate data sent into a radio signal. This same signal will be transmitted, via an antenna, to a decoder known as the router. Once decoded, the data will be sent to the Internet through a wired Ethernet connection.

As the wireless network works as a two-way traffic, the data received from the internet will also pass through the router to be coded into a radio signal that will be received by the computer's wireless adapter.

Welcome here and have a good knowledge with our community Gain total knowledge on any topic.                                                                NOTES OF  HEAT TRANSFER Methods of Heat Transmission There are three methods of heat transmission (i)   Conduction   In solids, heat is transmitted from temperature to lower temperature without actual movements the particles. This mode of transmission of heat. is conduction. (ii)  Convection  The process of heat-transmission in which particles of the fluid (liquid or gas) move. is called convection. Land breeze and see-breeze are formed due to convection. (iii)  Radiation  The process of heat transmission in the form electromagnetic waves, is called radiation. Radiation do not require any medium for propagation. It propagates without heating the intervening medium. The heat energy transferred by radiation, is called energy. Heat from the sun reaches the earth by radiation. Thermal Conductivity In

PERMUTATION AND COMBINATION

Welcome here and have a good knowledge with our community Gain total knowledge on this topic. PERMUTATION AND COMBINATION All possible arrangements of a collection of things, where the order is important. Example: You want to visit the homes of three friends Alex ("a"), Betty ("b") and Chandra ("c"), but haven't decided in what order. What choices do you have? Answer: {a,b,c} {a,c,b} {b,a,c} {b,c,a} {c,a,b} {c,b,a}  If the order does  not  matter, it is a Combination A  permutation  is an arrangement or ordering of a number of distinct objects. For  example , the words 'top' and 'pot' represent two different  permutations  (or arrangements) of the same three letters. Permutations  are for lists (order matters) and  combinations  are for groups (order doesn't matter). A joke: A " combination  lock" should really be called a " permutation  lock". The order you put the numbers in matters. Factori

Choose the correct answer: A thermodynamic state junction is a quantity (i) used to determine heat changes (ii) whose value is independent of path (iii) used to determine pressure volume work (iv) whose value depends on temperature only. Answer:  (ii) whose value is independent of path Question 2. For the process to occur under adiabatic conditions, the correct condition is: (i) ∆T= 0 (ii) ∆p = 0 (iii) q = 0 (iv)  w = 0 Ans.   (iii) q = 0 Question  3. The enthalpies of all elements in their standard states are : ‘ (i) unity (ii) zero (iii) < 0 (iv) different for each element Answer:   (ii) zero Question 4. Answer: Question 5. The enthalpy of combustion of methane, graphite and dihydrogen at 298 K are -890.3 KJ mol -1 , – 393.5 KJ mol -1  and – 285.8 KJ mol -1  respectively. Enthalpy of formation of CHJg) will be (i)
