The Long Term evolution is one of the standards for high speed wireless communication for mobile devices and data terminals based on the GSM and HSPA technologies. It helps in increasing the capacity and speed by using a different radio interface with core network improvement.LTE is an upgrade path for carriers with both GSM/UMTS networks and CDMA 2000 networks. The LTE frequencies and bands used in different countries mean that only multi band phones are able to use LTE in all countries where it is supported.There are two types of LTE which are as follows −LTE-TDDLTE-FDDLong-Term Evolution time-division duplex also ...

Frames Per Second or FPS is the rate at which back to back images called frames appear in a display and form moving imagery.Generally, the video content that we consume daily is not moving. They are still images played one after the other. Suppose if a video is shot at 24fps that means every frame is played back 24 times in a second. They change at a different rate across mediums depending on a lot of other factors.The frames per second used to the speed at which a camera can capture photos. The old cameras top-of-the-line pro bodies are capable ... Read More

A botnet is called as a collection of infected devices which are internet connected and these devices are controlled by the cyber-criminal with the help of malware. Usually, users are unaware of a botnet that is affecting their PC. Botnets normally used to send spam mails, create unusual traffic, etc.Botnet is installed on the PC which is vulnerable because of outdated firewalls or antivirus.Once the target device gets affected the attacker can control bots with two approaches −Client server approach − In this approach, first a server is set up which then sends commands to bots via communication protocol. After ... Read More
