A serial connection is a type of point-to-point connection used for WAN connections. It is used to connect one router to another. As we know, a wide area network is a type of network that consists of one or more routers, resulting in multiple subnet networks within a specific network topology. In the real world,

Access control lists are a fundamental part of network security. It helps us control access to a server, host, or subnetwork within a network by defining rules that permit or deny certain traffic flows. In our previous article, we covered the extended named ACL configuration. This article will focus on the extended numbered ACL configuration

TCP (Transmission Control Protocol) is a fundamental communication protocol that underlies many of our internet-based activities like web browsing, email, and file transfers. It is known for its reliability in ensuring data is sent and received accurately between host devices. In this article, we will give you an overview of TCP communication protocol and then

In our previous article, we introduced access control lists (ACLs) and went deep into standard numbered ACL configuration. Now, let’s take things a step further by diving into the extended named ACLs configuration, which offers more options to efficiently manage traffic within a network. This post is one of our series on ACL configuration. You

Access Control Lists (ACLs) are a fundamental component of network security. It helps us control traffic flow within a network based on defined rules. ACLs are categorized into two types: standard ACLs and extended ACLs. Standard ACL is further divided into standard-named ACL and standard-numbered ACL, while extended ACL is further divided into extended-named ACL

Access Control Lists (ACLs) are a fundamental part of network security. They serve as a tool to control traffic flow within a network, permitting or denying access based on defined rules. In Cisco Packet Tracer, ACLs come in two forms: Standard ACLs and Extended ACLs. Standard ACLs are further divided into standard named ACLs and

Due to the endless need for faster internet speeds, different Ethernet standards that support varying speeds have evolved. Early Ethernet networking equipment’s were running at a speed of 10 Mbps. Later, 100 Ethernet, often referred to as fast Ethernet, was developed, supporting a speed of 100 Mbps. Ethernet technology continued to advance, supporting speeds of

MPLS and IP routing are two packet forwarding technologies used in a network circuit. MPLS is a layer 2.5 packet forwarding technology that uses labels to make its packet forwarding decisions. This label is layer 2 information and contains data about the destination of any packet encapsulated in it. Read more on: MPLS Network Architecture

In this ever-evolving world of communication technology, modulation plays an important role in ensuring the successful transmission of signals from the sender to the receiver. Both 4G and 5G employ distinct modulation techniques to facilitate rapid and low-latency wireless communication. In this article, we delve into a comparison of 5G and 4G modulation techniques, aiming
4G Modulation vs. 5G Modulation Read More »
The fifth-generation (5G) networks are poised to adhere to a standard that demands reduced latency, high data rates, and optimized spectrum utilization, and the modulation technique used in this network generation plays an important role. Orthogonal Frequency Division Multiplexing (OFDM) is a prevalent modulation technique employed in 4G. However, OFDM’s high peak-to-average power ratios lead
