What is meant by clustering support?

Clustering support is the ability of a network operating system in a fault-tolerant group to connect multiple servers. The primary purpose of clustering is that if one server fails, the processing can continue with the next server in the cluster.

What do you understand by decoder?

The decoder is a type of circuit that converts the digital signal into an analog signal and encoded data into its original format.

DATA LINK LAYER WORK IN OSI MODEL

1. Modulation, or conversion between the representation of digital data in user equipment and the corresponding signals transmitted over a communications channel:

2. Demodulation, or conversion between the representation of digital data in user equipment and the corresponding signals received over a communications channel:

Modulation And Demodulation Process Physical Layer Work Is Manchester And Differential Menchester Encoding.

WHY HIKVISION NVR ADD A DAHUA IP CAMERA

It is possible to add a Dahua IP camera to a Hikvision NVR because both Hikvision and Dahua use the ONVIF protocol, which is an open standard for IP cameras. ONVIF allows devices from different manufacturers to communicate with each other, so you can add a Dahua camera to a Hikvision NVR, or vice versa.

TCP/IP MODEL

HISTORY OF TCP/IP MODEL THE TCP/IP MODEL WAS DEVELOPED BY VINT CERF AND BOB KAHN IN THE 1970S. THEY WERE BOTH WORKING AT THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) AT THE TIME. Vint Cerf And Bob Kahn CERF AND KAHN WERE TASKED WITH DEVELOPING A NEW NETWORK PROTOCOL THAT WOULD BE MORE RELIABLE AND EFFICIENT THAN THE EXISTING PROTOCOLS. THEY CAME UP WITH THE IDEA OF USING A LAYERED APPROACH, WHICH WOULD ALLOW EACH LAYER TO FOCUS ON A SPECIFIC TASK. THIS LED TO THE DEVELOPMENT OF THE TCP/IP MODEL, WHICH IS STILL THE BASIS FOR HOW DATA IS TRANSMITTED OVER THE INTERNET TODAY. CERF AND KAHN ARE OFTEN REFERRED TO AS THE "FATHERS OF THE INTERNET" FOR THEIR WORK ON THE TCP/IP MODEL. THEY WERE INDUCTED INTO THE NATIONAL INVENTORS HALL OF FAME IN 2004 FOR THEIR CONTRIBUTIONS TO THE DEVELOPMENT OF THE INTERNET. HERE ARE SOME OTHER NOTABLE PEOPLE WHO CONTRIBUTED TO THE DEVELOPMENT OF THE TCP/IP MODEL: JON POSTEL: POSTEL WAS THE FIRST CHAIRMAN OF THE INTERNET ENGINEERI...

Types Of Attack in Network

Common Network Attacks Explained. 1. Overwhelming a Network (DoS/DDoS): Imagine a restaurant that's flooded with too many customers. In a DoS/DDoS attack: A website is overwhelmed with too much traffic. 2. Eavesdropping on Conversations (MitM): Imagine someone listening in on your phone call. In a MitM attack: An attacker listens to your online conversations. 3. Tricking You (Phishing): Imagine receiving a fake email from your bank. In phishing: Attackers try to trick you into giving them your personal information. 4. Finding a Weakness in a Website (SQL Injection): Imagine finding a hole in a fence. In an SQL injection attack: An attacker finds a weakness in a website to steal or change data. 5. Planting a Hidden Camera (XSS): Imagine someone hiding a camera in a party. In an XSS attack: An attacker hides harmful code on a website to spy on you. 6. Guessing Your Password (Password Attck): Imagine trying to guess a friend's password. In a pas...

OSI Refrance Model

OSI MODEL 1. THE OSI MODEL WAS DEVELOPED BY THE INTERNATIONAL ORGANIZATION FOR STANDARDIZATION (ISO) IN THE LATE 1970S. THE MAIN ARCHITECT OF THE OSI MODEL WAS HUBERT ZIMMERMANN, A FRENCH SOFTWARE ENGINEER. 2. ISO REPRESENT A 1947 MORE THAN WORK AND AGAIN REPRESENTS A ISO IN 1977 AND MORE THAN WORK AN REPRESENT IN 1983 A OSI REDFRENCE MODEL. 2. HIS MODEL REPRESENT A 7 LAYER 3. OSI MEANS (OPEN SYSTEMS INTERCOMMUNICATIO). 1. APPLICATION LAYER 1. THE APPLICATION LAYER IS USED BY END-USER SOFTWARE SUCH AS WEB BROWSERS AND EMAIL CLIENTS. IT PROVIDES PROTOCOLS THAT ALLOW SOFTWARE TO SEND AND RECEIVE INFORMATION AND PRESENT MEANINGFUL DATA TO USERS. 2. IT SENDS ITS DATA TO THE FORM OF THE PDU. PROTOCLS AND DEVICES USED IN LAYER THERE ARE SOME PROTOCOLS THAT WORK AT THE BACKEND OF THE APPLICATION LAYER. WHICH IN TURN WORKS AT THE APPLICATION LAYER. MANY DEVICES USE IT AT THE APPLICATION LAYER. PROTOCOLS FTP (FILE TRANSOFER PROTOCOL) DNS (DOMA...
