Popularly known as NAT, Network Address Translation is a service that converts a private IP address to a public IP address and vice versa. Until now we have learned how every device that uses the Internet has its IP address. We have learned about the types of IP addresses, one of them being IPv4 addressing. … Read more
Till now, you must have learned about the Open Systems Interconnection (OSI) model. However, it is essential to know that the OSI model is now dominated by the TCP/IP model. In this blog, we will learn about the TCP/IP model. Once you learn about the TCP/IP model, you can quickly validate your networking knowledge. In … Read more
Wireless networks are a very important part of network architecture, especially for LAN architectures. They are present in combination with wired networks. Both of them form a complete network together. In the previous blog, we learned how wireless networks work. Note: If you haven’t read the previous blog of our CCNA 200-301 series, I highly recommend you do … Read more
In this blog, you will get introduced to the concept of wireless networks, especially Wireless Local Area Networks (LANs) using Wi-Fi. We will cover all the fundamentals of wireless LANs in Computer Networks in this blog. Note: If you haven’t read the previous blog of our CCNA 200-301 series, I highly recommend you do so. Make sure that you stick to the … Read more
The Spanning Tree Protocol (STP) is a network protocol that is situated in Layer 2 (Data Link Layer) of the Open Systems Interconnection (OSI) model. It was built to prevent the problems that arise when data is exchanged through computers over a Local Area Network (LAN). If 2-3 switches are connected together, they broadcast by … Read more
Switching is yet a very important topic to be covered for the Cisco Certified Network Associate (CCNA) 200-301 exam. Before we start learning about what is switching in computer Network, and its techniques, it is very important to learn about hubs and switches. Before you get introduced to the concept of switching, just keep in mind … Read more
Internet Protocol (IP) version 6 or IPv6 is a 128-bit address that can be divided into 16-bits blocks. It is represented in binary format. Due to the limited addresses generated by IPv4, the adoption of IPv6 and the types of IPv6 Addresses became popular. IPv6 has over 340 trillion unique addresses. Note: If you haven’t read the … Read more
What is CCNA? Cisco Certified Network Associate is an entry-level networking certification in IT. The CCNA course helps a candidate step into the world of networking by clearing the fundamentals of the domain. Cisco CCNA Certification comprises installing, switching, operating, and configuring networks and an in-depth understanding of security and automation. The Information Technology world … Read more
The Internet Protocol (IP) Address in CCNA course refers to a unique identification of any digital device that is connected to a computer network. Your smartphone, laptop, PC, and other devices have their own unique IP address. These IP Addresses allow your devices to communicate with each other. In technical terms, an IP Address is … Read more
OSI model in CCNA is a reference or conceptual model used to describe computer network communication. It stands for Open System Interconnection (OSI). The foundation of this model was kept forward by International Organization for Standardization (ISO) in 1984. Even if you’re entirely new to networking, it is very important to understand the OSI model … Read more
