Firewall

A firewall is a network security device that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules. Its purpose is to establish a barrier between your internal network and incoming traffic from external sources (such as the internet) in order to block malicious traffic like viruses and hackers. How …

EIGRP – Enhance Interior Getway Routing Protocol

EIGRP (Enhanced Interior Gateway Routing Protocol) is an advanced distance vector routing protocol. This protocol is an evolution of an earlier Cisco protocol called IGRP, which is now considered obsolete. EIGRP supports classless routing and VLSM, route summarization, incremental updates, load balacing and many other useful features. It is a Cisco propriatery protocol, so all routers in …

Routing Protocol

Dynamic routes are routes learned via routing protocols. Routing protocols are configured on routers with the purpose of exchanging routing information. There are many benefits of using routing protocols in your network, such as: unlike static routing, you don’t need to manually configure every route on each router in the network. You just need to …

IP Address – IPV4 Vs IPV6

An IP address, or simply an “IP,” is a unique address that identifies a device on the Internet or a local network. It allows a system to be recognized by other systems connected via the Internet protocol. There are two primary types of IP address formats used today — IPv4 and IPv6. IPv4 An IPv4 address consist of four sets of numbers …

TCP/IP Model

TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP can also be used as a communications protocol in a private network (an intranet or an extranet). Why we need a new Model when we have OSI Model? ► Although the OSI reference model is universally recognized, the historical and …

OSI Model

The Open System Interconnection (OSI) model defines a networking framework to implement protocols in seven layers. There is really nothing to the OSI model. In fact, it’s not even tangible. The OSI model doesn’t perform any functions in the networking process. It is a conceptual framework so we can better understand the complex interactions that are happening. Who Developed the OSI …

Introduction to Networking

What is Networking? Networking can be define as a communication between one or multiple networking devices. The main aim of networking is share resources between devices. A computer network is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes. These …
