Distribuation Layer Swiitch

ENTERPRISES:

ENTERPRISES USE DISTRIBUTION LAYER SWITCHES TO CONNECT THEIR ACCESS LAYER SWITCHES TO THEIR CORE LAYER SWITCHES. THIS ALLOWS THEM TO CREATE A HIERARCHICAL NETWORK THAT IS SCALABLE, RELIABLE, AND SECURE.

DATA CENTERS:

DATA CENTERS USE DISTRIBUTION LAYER SWITCHES TO CONNECT THEIR SERVERS AND OTHER DEVICES TO THE CORE NETWORK. THIS ALLOWS THEM TO PROVIDE HIGH-PERFORMANCE NETWORKING FOR THEIR APPLICATIONS.

SERVICE PROVIDERS:

SERVICE PROVIDERS USE DISTRIBUTION LAYER SWITCHES TO CONNECT THEIR CUSTOMERS TO THEIR NETWORKS. THIS ALLOWS THEM TO PROVIDE A VARIETY OF SERVICES, SUCH AS BROADBAND INTERNET, IPTV, AND VOIP.

GOVERNMENT AGENCIES:

GOVERNMENT AGENCIES USE DISTRIBUTION LAYER SWITCHES TO CREATE SECURE AND RELIABLE NETWORKS FOR THEIR EMPLOYEES AND CITIZENS.

EDUCATIONAL INSTITUTIONS:

EDUCATIONAL INSTITUTIONS USE DISTRIBUTION LAYER SWITCHES TO CONNECT THEIR CLASSROOMS, LABS, AND OTHER FACILITIES TO THE NETWORK. THIS ALLOWS THEM TO PROVIDE STUDENTS AND FACULTY WITH ACCESS TO THE RESOURCES THEY NEED.

IN GENERAL, ANY ORGANIZATION THAT NEEDS TO CREATE A SCALABLE, RELIABLE, AND SECURE NETWORK WILL LIKELY USE DISTRIBUTION LAYER SWITCHES.

HERE ARE SOME SPECIFIC EXAMPLES OF HOW DISTRIBUTION LAYER SWITCHES ARE USED IN DIFFERENT ORGANIZATIONS:

A LARGE ENTERPRISE MIGHT USE DISTRIBUTION LAYER SWITCHES TO CONNECT THE ACCESS LAYER SWITCHES IN ITS DIFFERENT BUILDINGS TO THE CORE SWITCHES IN ITS DATA CENTER.

A CLOUD COMPUTING PROVIDER MIGHT USE DISTRIBUTION LAYER SWITCHES TO CONNECT ITS SERVERS TO ITS CORE NETWORK, WHICH IS THEN CONNECTED TO THE INTERNET.

A TELECOMMUNICATIONS COMPANY MIGHT USE DISTRIBUTION LAYER SWITCHES TO CONNECT ITS CUSTOMERS TO ITS BROADBAND INTERNET NETWORK.

A GOVERNMENT AGENCY MIGHT USE DISTRIBUTION LAYER SWITCHES TO CREATE A SECURE NETWORK FOR ITS EMPLOYEES AND CITIZENS TO ACCESS GOVERNMENT SERVICES.

A UNIVERSITY MIGHT USE DISTRIBUTION LAYER SWITCHES TO CONNECT ITS CLASSROOMS, LABS, AND OTHER FACILITIES TO THE NETWORK, SO THAT STUDENTS AND FACULTY CAN ACCESS THE RESOURCES THEY NEED.

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...

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...
