Learn different types of networks in computer networking. What is Peer to Peer & Client Server network.
5 Types of network topologies. Start, Bus, Ring, Mesh, and Hybrid Topology. Learn how system communicate.
Various types of media are used to transmit the data between source and receiver.
Router, Switch, Hub, Repeater, NIC, Gateway, and many more are networking devices that could be used as centralized deviced.
The OSI mannequin has seven hierarchical layers. Each layer describes a special community that performs.
The OSI has seven layers and the TCP/IP mannequin has 4 or 5 layers relying on totally different preferences.
Here you will learn about the binary number system. What is a binary calculator? How to do binary to decimal conversion?
DNS is an internet service that translates domain names into IP addresses. Because domain names are alphabetic, they’re easier to remember.
FTP is built on server-client architecture and uses separate control and data connection between the client and the server.
An IMAP server typically listens on port number 143. IMAP over SSL (IMAPS) is assigned port number 993. The current version of IMAP is version 4.
SSH was designed as a replacement for Telnet and for unsecured remote shell protocols. The standard TCP port 22 has been assigned
IP has the task of delivering packets from the source host to the destination host solely based on the IP address in the packet header.
An IP address is a 32-bit number assigned to every host on a network. IP Address In Networking is known as a mixture of a Network ID and Host ID.
After learning the IP address and binary calculator, let’s move to subnetting.Subnetting is logically dividing the network by extending the 1’s utilized in Subnet Mask.
VLSM – Variable Length Subnet Mask is also known as classless subnetting, subnet may have different numbers of hosts...
The process of taking a range of IP addresses and advertising them in one address block is known as summarization or route summarization.
What Is A Router – A router is a networking device that forwards data packets between computer networks.
Each IOS device has two main components: hardware and software. Almost every IOS-based router...
ser Mode is the first mode a user has access to after logging into the router. User Mode is the first mode a user ...
Router load and run the POST (Located in ROM), testing the hardware component, including memory...
Sending a packet from one router to another router means routing. It refers to the process of selecting the shortest
IGP is used to learn the route of an single organization. For example, an organization has 200 branches
Mask is not sent as part of update. They will automatically summarize at classfull boundary. It may lead to suboptimal path forwarding.
If a router learns about multiple different paths to the same network from the same routing protocol,
The Reliable Transport Protocol (RTP) manages the delivery and reception of EIGRP packets. Reliable delivery means that delivery is guaranteed and that packets will be delivered in order
RIP Routing Protocol – The full of RIP is Routing Information Protocol is a distance-vector, Interior Gateway Protocol (IGP)
Interior Gateway Routing Protocol (IGRP): IGRP is a distance-vector Interior Gateway Protocol (IGP) developed by Cisco.
The protocol was designed by Cisco Systems as a proprietary protocol, available only on Cisco routers.
OSPF protocol was developed in order to solve the problem of large-scale routing and to introduce a high functionality
For communication between two different networks, we configure the routing protocol. But basic configuration is required i
Dynamic Host Configuration Protocol (DHCP) is a protocol that was invented to address some problems like, in our network
NTP Server is a protocol that synchronizes the clocks of your network devices.
This command should be use when configuration register value is set to it’s default value i.e. 2102
How to set a password for user mode? how to set a password for privileged mode?
An ACL (Access List) is a list of statements that are meant to either permit or deny the movement of data from the
NAT (Network Address Translation) allows a network device such as a router or firewall to translate addresses
There are three types of IPv4 addresses, unicast, multicast, and broadcast. In IPv6, broadcast addresses
The switch is a computer networking device that connects devices together on a computer network, by using packet switching to receive and process
A collision domain is a set of LAN interfaces whose frames could collide with each other, but not with frames set
Spanning-Tree Protocol (STP) is a loop-prevention protocol used in a switching environment.Spanning-Tree Protocol (STP) is a loop-prevention
Ethernet LAN switches use a very cool system called transparent bridging to create their address lookup tables.
All interfaces on a Cisco switch are turned on by default. This means that an attacker could connect his laptop to your network through a wall socket and
VLAN definition: A Virtual Local Area Network (VLAN) is a logical grouping of network users and resources connected to administratively defined ports on a
Inter-VLAN Routing can be defined as a way to forward traffic between different VLANs by implementing a router in the network.
The VLAN Trunking Protocol is organized into management domains. A Cisco VTP domain is one switch or several
Frame tagging is used to identify the VLAN that the frame belongs to in a network with multiple VLANs. The VLAN ID is placed on the frame when it
What Is Radius Server/ How Radius Server Authentication Works?
What Is A Tacacs Server? How To Configure Tacacs Server
What Is Secure Shell In Networking And How To Configure SSH?
Typically LAN connection is used within the company and WAN allows you to connect to remote locations,
The sending and receiving of data from a source device to the destination device are possible with
Cisco HDLC is based on ISO’s standard. One of the problem of with ISO’s HDLC is that it does not define how to carry
Frame-relay is layer 2 packet-switching WAN technology, it is connection-oriented: a layer 2 connection must be established before
