SOFTWARE EXAMPLE(CISCO PACKET TRACER)

I will illustrate how can we create a simultaneous GSM network by using Cisco Packet Tracer.

In the begging, I create a surveillance office, then connect them together as a network with different IP by switch device, which is also linked to the central office server. After that, I use 3 relay towers and link them to the central office server. The following picture shows the destination of the call from smart devices to the telecom provider and opposite.

My First Step in the Technological World

(Wondershare Group., 2020) Well👀 I think you are waiting for my story with the Technology💻. I used to collect many types of computer when I was 15 years, it was one of my interests. I have been developing my skills in Technological space which contributed to change my concept about the Technology. In Saudi Arabia, the Saudi Federation for Cybersecurity and programming are interesting in development and encouragement the Technology Fields in many ways 📣; I was very excited to discover where I can find my self in this project?💭They have been doing many conferences about the latest science in the field of Technology📷, and made technology competitions and many courses in Cybersecurity, Programming, Encryption and many other sections participating by many computer experts. In 2018, the biggest Hackathon in the middle east was in Saudi Arabia called HACKATHON ALHAJJ, which supported by GOOGLE. Many programmers and designers competed to find an application to help visitors of MA
