NFC

-

 NFC (Near Field Communication) is a short-range wireless technology that allows devices to communicate with each other when they are brought close together, typically within a distance of less than 10 centimeters. It is based on the ISO/IEC 18092 standard and uses the 13.56 MHz frequency band.

  • NFC uses two different communication modes:
    • Peer-to-peer mode, in which two devices can communicate with each other and exchange data.
    • Reader/writer mode, in which a device, such as a smartphone or a point-of-sale terminal, can read data from a passive tag or a smart card.
  • NFC devices, such as smartphones and smartwatches, can be used to make contactless payments, access public transportation, and share data with other NFC devices.
  • NFC devices can also be used for access control, such as opening doors or starting cars.
  • NFC tags are small, passive devices that can be placed on objects and can store a small amount of data, such as a web URL or a phone number.
  • NFC tags can be read by any NFC-enabled device and do not require any power source.
  • NFC can also be used to pair devices with Bluetooth or WiFi, by bringing them close to each other and establish a wireless connection.
  • NFC technology is supported by most of the mobile operating systems such as Android and iOS.
  • NFC technology is widely used in mobile payments, public transportation, and other mobile-based applications

It's worth noting that NFC technology is constantly evolving and changing, so the information I've provided is accurate at the time of my knowledge cut-off and there may be newer developments or advancements in the field.

  What is Computer? A computer is an electronic device that manipulates information or data. It has the ability to store, retrieve, and process data. Nowadays, a computer can be used to type documents, send email, play games, and browse the Web. It can also be used to edit or create spreadsheets, presentations, and even videos. Functions of Computer:  A Computer can perform the following set of functions:  1. Accept data   2. Store data   3. Process data as desired  4. Retrieve the stored data as and when required  5. Print the result in desired format. Components of Computer: It mainly has two major components:  i. Hardware         1. Input Device         2. Output Device         3. Storage Device    ii. Software          1. System Software         2. Application Software         3. Utilities Softwa...

                      First Generation Computer   First Generation: 1946-1959 is the period of first-generation computer.  J.P. Eckert and J.W.  Mauchy invented the first successful electronic computer called ENIAC, ENIAC stands for “Electronic Numeric Integrated and Calculator”.  Few Examples are:   ENIAC   EDVAC  UNIVAC   IBM-701   IBM-650 Advantages:  1. It made use of vacuum tubes which are the only electronic component available during those days.  2. These computers could calculate in milliseconds. Disadvantages: 1. These were very big in size, weight was about 30 tones.  2. These computers were based on vacuum tubes. 3. These computers were very costly.  4. It could store only a small amount of information due to the presence of magnetic drums. 5. As the invention of first-generation computers involves vacuum tubes, so another ...

Z-WAVE

-
  Z-Wave is a wireless communication protocol that is used for home automation and other low-power, low-data-rate applications. It is based on the ITU-T G.9959 standard and uses the 908.42 MHz frequency band. Z-Wave devices can be used to create a mesh network, in which each device can act as a relay for other devices, allowing for a larger coverage area. Z-Wave devices are typically used in home automation, industrial automation, healthcare, and other applications that require low-power, low-cost, and low-data-rate wireless communication. Z-Wave devices can be powered by batteries and have a longer battery life compared to other wireless technologies. Z-Wave networks can be secured using AES-128 encryption. Z-Wave Alliance is a group of companies that develop and promote Z-Wave technology. Z-Wave devices can be connected to other networks using Z-Wave-to-IP gateways, which allow for remote control and monitoring of Z-Wave devices over the Internet. Z-Wave devices can be integrated...
