Using satellites, a system called GPS or Global Positioning System has been revolutionized into the modern world. Using satellite navigation, you can predict with accuracy the exact destination of a vehicle traveling at high speed through the streets. How GPS Navigates You through Your Journey In this example, we will see how NASA has successfully used satellites to map out the Earth's surface using images. In fact, NASA is able to obtain images of almost the entire surface of the Earth at least at one point in time. Using satellites, the maps could be updated continuously without any gap. GPS systems In fact, GPS systems are extremely accurate. If the driver follows a particular road for some time, the system can always find the precise place to avoid road rash accidents. Furthermore, GPS technologies are also reliable and effective. In other words, technology can provide people with safe routes through real situation

                                  An Internet Protocol address (IP address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing. The IP address space is managed globally by the Internet Assigned Numbers Authority (IANA), and by five regional Internet registries (RIRs) responsible in their designated territories for assignment to local Internet registries, such as Internet service providers, and other end users. IPv4 addresses were distributed by IANA to the RIRs in blocks of approximately 16.8 million addresses each, but have been exhausted at the IANA level since 2011. Only one of the RIRs still has a supply for local assignments in Africa. Some IPv4 addresses are reserved for private networks and are not globally unique. Network administrators assign an IP address to each device connected to a

'' VFX" redirects here. For the 196p8 US Navy fighter program, see VFX. Visual effects  are the process by which imagery is created or manipulated outside the context of a live-action shot in filmmaking. Visual effects involve the integration of live-action footage (special effects) and generated imagery (digital or optical effects) to create environments, inanimate objects, animals or creatures which look realistic but would be dangerous, expensive, impractical, time-consuming or impossible to capture on film. Visual effects using computer-generated imagery (CGI) have recently become accessible to the independent filmmaker with the introduction of affordable and relatively easy-to-use animation and compositing software. Timing Visual effects are often integral to a movie's story and appeal. Although most visual effects work is completed during post-production, it usually must be carefully planned and choreographed in pre-production and production. Wh
