THE FIRST CISCO SWITCH DEVOLPED

INITIAL CATALYST SWITCHES (1993-1994):

WHILE CISCO HAD BEEN FOCUSED ON ROUTERS, THE FIRST "CISCO" SWITCHES ACTUALLY ORIGINATED FROM ACQUISITIONS IN THE EARLY 1990S.

IN 1993, CISCO ACQUIRED CRESCENDO COMMUNICATIONS, ACQUIRING THEIR ETHERNET SWITCHING TECHNOLOGY USED IN THE CATALYST 5000 AND 6000 SERIES.

IN 1994, THEY ACQUIRED KALPANA, WHICH BROUGHT THE CATALYST 3000 SERIES BASED ON THEIR FAST ETHERNET SWITCHING TECHNOLOGY.

CISCO CRESCENDO COMMUNICATIONS WAS A PRIVATELY HELD NETWORKING COMPANY ACQUIRED BY CISCO SYSTEMS IN 1993.

THEY SPECIALIZED IN DEVELOPING AND MANUFACTURING HIGH-PERFORMANCE WORKGROUP SOLUTIONS FOR DESKTOP COMPUTERS WITHIN LOCAL AREA NETWORKS (LANS).

CISCO ACQUIRED KALPANA IN OCTOBER 1994 FOR APPROXIMATELY $204 MILLION IN STOCK. KALPANA WAS A PRIVATELY HELD COMPANY CONSIDERED THE LEADING PROVIDER OF ETHERNET SWITCHES AT THE TIME. THEIR ACQUISITION WAS A SIGNIFICANT MILESTONE FOR CISCO'S ENTRY INTO THE ETHERNET SWITCHING MARKET.

DOS AND DDOS ATTACK

A Dos (Denial-Of-Service) Attack and A DDOS (Distributed Denial-Of-Service) Attack Are Both Attempts to Make a Computer System or Network Resource Unavailable to Legitimate Users. However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once. ...

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...
