LAN is a type of network which is used to connect devices within a limited area. LAN is limited to a building, church, school, or small geographical area. Ethernet and power over the Ethernet are the most popular LAN technologies used today. Cost efficiency, Installed base, Maintainability, and Performance are factors considered while selecting the ...
The Simple Network Management Protocol (SNMP) in computer networks is an Internet Standard protocol for gathering, organizing, and altering information about managed devices on IP networks to affect the behavior of the devices. SNMP in computer networks is commonly supported by cable modems, routers, switches, servers, workstations, printers, and other devices.For network monitoring, SNMP is ...
When a device is within its home network in an IP network, routing is based on static IP addresses. The IP address assigned to the device on the network connects it to the network via standard IP routing. This is similar to how a postal letter is delivered to the specified address on the envelope. ...
In controlled access protocols, communication on a shared medium is regulated to prevent data collisions. Each station consults with others to determine which has the transmission right, allowing only one node to send data at a time. This method ensures efficient data transfer without conflicts. The three primary controlled access techniques are Reservation, Polling, and ...
Access Control Lists (ACLs) are a collection of permit-and-deny restrictions, also known as rules, that offer security by preventing unauthorized users from accessing particular resources and granting authorized users access. Additionally, ACLs can govern traffic flow, limit the information in routing updates, and determine which types of traffic are sent or denied. ACLs often sit ...
CRAM stands for Challenge Response Authentication Mechanism and it is a set of protocols used for authenticating a user by giving them a challenge and access is provided to the user only if they answer the challenges correctly.CAPTCHA is one example of Challenge Response Authentication. Introduction The Challenge Response Authentication mechanism is abbreviated as CRAM ...
An active directory is used for the management of computers and other devices on a network. Active Directory is a directory service that runs on Microsoft Windows Server. It is used for identification and also provides access management. Active Directory Domain Services (AD DS) is the most important component of Active Directory. The hierarchal structure ...
Traceroute is the most preferred tool that network engineers make use of to troubleshoot networks. It was innovated in 1987 and remains extremely relevant these days. Traceroute may be a widely handed-down command-line benefit accessible in nearly all operating systems. It manifests you the entire route to a goal address. It also manifests the time ...
In Carrier Sense Multiple Access (CSMA) protocol, the station will sense the channel before the transmission of data. CSMA reduces the chances of collision in the network but it does not eliminate the collision from the channel. 1-Persistent, Non-Persistent, P-Persistent, and O-Persistent are the three access methods of CSMA. What is Carrier Sense Multiple Access ...
Dynamic Trunking Protocol is a set of rules and properties that is used for carrying the traffic over the network when there is more than one VLAN (virtual local area network) in the network. This protocol was developed by the company named CISCO Systems. In the Dynamic Trunking Protocol, any interface can be set to ...
