Computer Network Topology Outline
The first thing that has to study about a network is its physical shape or design layout. It will be extremely important when a wiring scheme and design are selected for a new network installation. Actually Network Topology refers to physical shape or design layout of a network. Network topology determines how different nodes in a network are connected and how these nodes communicate to each other. Types of Computer Network Topology Network really has two shapes or two types of topology. Physical topology Logical topology Physical Topologies The physical topology is the physical shape or layout of the wires that can be visible in a network. The Physical topology defines how devices are interconnected with or without wires. Physical topology is further divided into two sections. Point-to-point connections Multipoint connections Point-to-point connections In a point-to-point connection, a communication link is established between two devices with one wire or air (in the case of wireless). A simple example of point-to- point connection is talking over telephone between two persons where anyone else is not allowed to use the phone on either side. Multipoint Connection Multiple devices or machines are involved in a multipoint connection. These devices mainly share cabling but [...]

MikroTik VLAN Routing Configuration with Manageable Switch | July 11, 2018
A VLAN (Virtual LAN) is a group of computers, servers, network printers and other network devices that behave as if they were connected to a single network. VLAN is a logical topology that divides a single broadcast domain into multiple broadcast domains. VLAN is a layer 2 method. So, a manageable switch is required to manage VLAN in your network and a router is required to route and control your inter-VLAN. VLAN increases network security and performance as well as [...]

MikroTik VPN Configuration with PPTP (Connecting Remote Client) | August 17, 2016
VPN (Virtual Private Network) is a technology that extends private network across a public network. It enables private network users to send and receive data across public network as if their network devices were directly connected to the private network. There are many VPN services in MikroTik RouterOS 7. Among them, MikroTik PPTP is a mostly used VPN service. It is a client-server VPN technology. So, a user can access server, printer, IP phone and any other network devices of [...]

What Are the 7 Layers of OSI Model and How Do They Work | October 5, 2021
The OSI Model stands for Open Systems Interconnection Model, a conceptualized framework used to describe the seven layers of a telecommunication system or network. It was established as an international standard in the year 1984 by the International Organization for Standardization. This model helps visualize how networks operate and is still used today to figure out and solve network problems, such as by a web development company. In this article, we will talk about the 7 layers of the OSI [...]

MikroTik Router Web Proxy Configuration | August 28, 2016
A Proxy Server is usually placed between users and the internet so that the proxy server can track the activities of any user. Formerly, a proxy server was mainly used for caching the static content of any web server because the internet speed was too slow. So, users would get high speed for browsing as if they were browsing a local server. But nowadays the internet bandwidth has increased. So, the proxy server is usually not used for web caching [...]

MikroTik Site to Site VPN Configuration with IPsec | March 8, 2018
VPN (Virtual Private Network) is a technology that provides a secure and encrypted tunnel across a public network. A private network user can send and receive data to any remote private network using this VPN Tunnel as if his/her network device was directly connected to that private network. Site to Site VPN technique establishes a secure tunnel between two routers across public network and local networks of these routers can send and receive data through this VPN tunnel. MikroTik RouterOS [...]

How to Block MAC Address in MikroTik RouterOS 7 | July 11, 2024
MikroTik RouterOS 7 by default allows any MAC address to get internet connection through it. But we may need to block some MAC addresses sometimes. There are three methods to block MAC address in MikroTik RouterOS 7 – Blocking MAC Address using Bridge Filter Rule. Blocking MAC Address using Firewall Filter Rule and Blocking MAC Address from DHCP Lease. We can use any of these methods if we want to block MAC Address in MikroTik Router. In this article, we [...]
