WHAT IS A NETWORK

A GROUP OF COMPUTERS WHICH ARE CONNECTED TO EACH-OTHER FOR THE PURPOSE OF SHARING THEIR RESOURCES  IS CALLED NETWORK.

A NETWORK CONSISTS OF TWO OR MORE COMPUTERS.THAT ARE LINKED IN ORDER TO SHARE RESOURCES (SUCH AS PRINTERS AND CDS), EXCHANGE FILES, OR ALLOW ELECTRONIC COMMUNICATIONS. 

THE COMPUTERS ON A NETWORK MAY BE LINKED THROUGH CABLES, TELEPHONE LINES, RADIO WAVES, SATELLITES, OR INFRARED LIGHT BEAMS.

INVENTION OF  NETWORK

COMPUTER NETWORKS WERE FIRST DEVELOPED IN THE LATE 1950s FOR MILITARY AND DEFENSE USA.

THEY WERE INITIALLY USED TO TRANSMIT DATA OVER TELEPHONE LINES AND HAD LIMITED COMMERCIAL AND SCIENTIFIC APPLICATIONS.

WITH THE ADVENT OF INTERNET TECHNOLOGIES, A COMPUTER NETWORK HAS BECOME INDISPENSABLE FOR BUSINESSES.

CSST COURSE 1.0

Q1. WHAT IS A ADDRESSING. Network addressing is like a two-part delivery system:   Logical Addressing (IP): This is like your permanent address (e.g., 192.168.1.1) that lets data find your device anywhere on the internet. Physical Addressing (MAC): Think of this as a unique ID for your device's network card (AA:BB:CC:DD:EE:FF) used for local delivery within your network. Q2. WHAT IS A PACKET AND FRAME . Packets: Layer: Network Layer (Layer 3) Content: The actual data you want to send, like an email, a video, or website information. Addressing: Contains logical addresses (IP addresses) to identify the sender and receiver on the network. Size: Can vary depending on the data type, but generally larger than frames. Travels across networks: Packets can travel across different networks, like the internet, as they are routed based on IP addresses. Frames: Layer: Data Link Layer (Layer 2) Content: The packet wrapped with additional information for local deliver...

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. ...
