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

A wireless Local Area Network (WLAN) is a local area network that uses radio waves to provide connectivity to end-host devices rather than the typical Ethernet cables used in a traditional LAN. WLAN offers several advantages over a standard LAN because it allows users to maintain their network connection even as they travel a certain

A local area network (LAN) is a network architecture that is often mistaken for a wide area network (WAN) or Metropolitan Area Network (MAN); however, it has distinct differences from them. A Local Area Network (LAN) is utilized to provide internet connectivity within a limited area, typically a building, room, or even just one or

2G phones were the first mobile phones to utilize packet-switched technology for handling signal transmission between the transmitter and the receiver. These phones operates on second-generation networks which is built upon GSM and other network standards. 2G phones offer various features that revolutionized telecommunications, including digital modulation of signals, direct dialing, multiple access media transmission,

MPLS and E-LAN are two networking technologies that aid in the distribution of packets in a network. Multiprotocol Label Switching (MPLS) is a layer 2.5 packet forwarding protocol that uses labels to efficiently forward data packets in a network. E-LAN, on the other hand, is a technology that interconnects different LANs in a Metropolitan area
