Day 4 of #100DaysOfCyber Answer: 🟢 Fibre optic cable Fibre converts electrical signals into light pulses light travels faster and further with less signal loss than copper or Wi-Fi. That’s why enterprises and large networks use it over copper wire. #NetworkingBasics

In cloud servers, never bind internal admin interfaces to 0.0.0.0 unless you have a firewall. Someone will find it. #Localhost #NetworkingBasics #DevOpsJourney #LoopbackAddress

Day 3 of #100DaysOfCyber 🔐 Quick question for my cybersecurity beginner friends 👇 What carries data the fastest? 🔴 Copper wire 🟡 Wi-Fi 🟢 Fibre optic cable Drop your answer before I drop the explanation tomorrow. 👀 #100DaysOfCyber #NetworkingBasics

dig google.com and nslookup google.com are your best friends for debugging DNS. Try them. #DNS #DomainNameSystem #NetworkingBasics #CloudJourney

Day 2 of #100DaysOfCyber 🔐 Every device on a network is either a client or a server. Sometimes both. Today I covered network components, how ISPs connect you to the internet, and what actually sits between your device and the web. #NetworkingBasics #CiscoNetAcad

Day 21/100 🚀 Completed Module 2: Network Components, Types, and Connections in the Cisco Networking Basics course. 🌐 Learned about network components, network types, device connections, and ISP connectivity options. ✅ #100DaysOfLearning #CiscoNetworking #NetworkingBasics

Day 1 of #100DaysOfCyber 🔐 A signal = electrical or optical patterns between devices. That’s literally the internet. Bits → bytes → ASCII → signals through copper, fibre, or air. Today I broke down how data actually moves. #NetworkingBasics #CiscoNetAcad

🛜🛜🛜 Networking Basics: How DNS, IP Addresses, and VPNs Work Networking is the invisible foundation that lets every device communicate on the internet. Here’s a simple breakdown of the three key technologies that power it: DNS (Domain Name System) Think of DNS as the internet’s phonebook. When you type “google.com”, DNS translates the human-readable name into a numerical IP address that computers can understand. Without DNS, you’d have to remember long strings of numbers instead of easy website names. IP Addresses Every device connected to the internet has a unique IP address — like a digital home address. There are two main types: • IPv4 (e.g., 192.168.1.1) • IPv6 (much longer, designed for the future) IP addresses tell data packets exactly where to go. VPN (Virtual Private Network) A VPN creates an encrypted tunnel between your device and the internet. It hides your real IP address, encrypts your traffic, and lets you browse securely — especially on public Wi-Fi. It also helps bypass geo-restrictions and improves privacy. Together, DNS makes the web user-friendly, IP addresses handle routing, and VPNs keep everything secure and private. These three technologies working in harmony make modern internet browsing fast, reliable, and safe. #NetworkingBasics #HowDNSWorks #IPAddress #VPNExplained #CyberSecurity

Day 47✅ Still working on the Packet Tracer activity 🧑‍💻.. Slow days still count I guess.. #100DaysofCybersecurity #networkingbasics #LearninginPublic

Week 5 on TryHackMe: Learned how packets & frames actually move data. Now I see why: • Networks fail • Data gets delayed • Connections drop It’s all happening at this level. @tryhackme #NetworkingBasics #LearnInPublic #EthicalHacking

Day 16 of NetworkingBasics on @LearningatCisco ✅ I'll be learning about Application Layer Services, the Client Server Relationship, Network Application Services, Domain Name Systems, Web Clients and Servers, FTP Clients and Servers, Virtual Terminals, Email and Messaging.

Day 15 of #NetworkingBasics on @LearningatCisco ✅ I'll be learning about TCP and UDP, and Port Numbers.

Day 3 and 4 of the 30days cybersecurity challenge. I wasn't able to post yesterday, so I will do it for both days. I was able to start networking basics on cicso and tryhackme. #CyberSecurity #Networkingbasics #TechJourney #TryHackMe #Learning @nacss_uniosun @malik_cybersec

Day 14 of #NetworkingBasics on @LearningatCisco ✅ I'll learn Routing Between Networks, the need for Routing, the Routing table and also to create a Local Area Network.

🎉 Just completed Networking Basics with Cisco Networking Academy! Strengthened my networking foundations and ready for more advanced skills. 💻✨ #CiscoNetworkingAcademy #NetworkingBasics #ITSkills

Day 15 of #100daysofcybersecurity Peer-to-peer network consists of two directly connected computers where both computers are able to exchange data and services with each other, acting as either a client or a server as necessary #cloudsecurity #cybersecurity #networkingbasics

Day 9 of #NetworkingBasics on @LearningatCisco ✅ I'll be learning about IPv4 and Network Segmentation, IPv4 Unicast, Broadcast and Multicast, and types of IPv4 Addresses.
