This week’s topic was DHCP. DHCP is Dynamic Host Configuration Protocol. This is the name of the Protocol responsible for dynamic configuration of the network node using the OSI model. DHCP has received a new application implementation for modern IPv6. Each device connected to the network needs a unique IP address. Network administrators assign staticContinue reading “DHCP”

ACLs
ACL’s on Cisco routers allow to solve two groups of tasks:1. traffic filtering;2. traffic classification.ACL’s can be attributed to packet filtering firewalls. That is, they allow you to filter packets by five parameters:1. Source IP address2. Destination IP address3. Protocol encapsulated in an IP packet4. Source port5. Port of destination⠀ACL’s are divided into 2 types:1.Continue reading “ACLs”
VLANs
By tradition, this post is dedicated for weekly review of studying CCNA course. And this week we’ve learnt about VLANs. What are them and why do we need them? Let’s traverse through topic briefly⬇️ VLAN (Virtual Local Area Network) is a feature in routers and switches that allows you to create multiple virtual local areaContinue reading “VLANs”
Switched Networks
This week we leaned two chapters called Switched Networks and Switch Configurations. Switches are devices that are used to connect several devices in the same network. They direct and control data flow at the access layer of networks. Nowadays, networks are developing every day to deal with business problems better. Users expect to get instantContinue reading “Switched Networks”
Dynamic routing
First, let’s deal with the concept of “dynamic routing”. Up to this point, we used static routing, that is, we prescribed a routing table on each router with our own hands. The use of routing protocols allows us to avoid this tedious monotonous process and errors associated with the human factor. As the name implies,Continue reading “Dynamic routing”
Network layer
We are all familiar with Windows. This is the operating system, the first and main set of programs loaded into the computer. Network devices such as switches, routers etc are using their operating system. It is called the Internetwork Operating System (IOS). With IOS, we set up and configure devices. We enter the commands forContinue reading “Network layer”
Ethernet
On this week we learned Chapter 5 called Ethernet. Ethernet is LAN technology that connects computers together. First Ethernet technology was published and sold in 1980 by consortium of Digital Equipment Corporation, Intel and Xerox. Then open standards were created for everyone, such that every user could benefit. Then, in 1985 The Institute of ElectricalContinue reading “Ethernet”
Data link layer,physical layer.
Hello guys, how are you? I am fine and as you already understood, there is new part of my project. In this post, I am going to write about last week’s learning process. If you are interested, you can read and get short view about topic and our lessons.. This week’s topics were Data LinkContinue reading “Data link layer,physical layer.”
IPv4, IPv6 and Ethernet
Hi guys. Today there is another blog on the topic – “IPv4, IPv6 and Ethernet”. This week has been very very exciting and fascinating. After all, because this week we listened to a lecture on a very interesting topic and in practice we connected Ethernet. IPv4 (Internet Protocol version 4) is the fourth version ofContinue reading “IPv4, IPv6 and Ethernet”
