Introduction

• What is Latency?
• Latency refers to the delay or lag in data
  transmission between two points in a network.
• It is measured as the time it takes for a data
  packet to travel from the source to the
  destination and back.

Importance of Latency

• Why Latency Matters
• Affects the speed of online activities like
  gaming, streaming, and video conferencing.
• Lower latency means faster response times and a
  smoother user experience.
• High latency can lead to lag, buffering, and
  delays.

How Latency is Measured

• Testing Process
• Use tools to send data packets between your
  device and a server.
• Measure the time taken for the packets to make
  the round trip
• .
• Key Metrics
• Round Trip Time (RTT) Total time for data to
  travel to the server and back.
• Ping Common tool used to measure latency.

Factors Affecting Latency

• Network Congestion
• High traffic can increase latency.
• Distance
• Longer distances between the source and
  destination can add to latency.
• Network Hardware
• Quality of routers and switches can impact
  latency.
• Server Load
• Overloaded servers can introduce delays.

Improving Latency

• Tips for Optimization
• Use wired connections instead of wireless for
  lower latency.
• Optimize network settings and upgrade hardware if
  necessary.
• Choose servers closer to your geographical
  location.
• Minimize background applications that use
  bandwidth.

Real-World Applications

• Impact on Different Activities
• Gaming Low latency is crucial for real-time
  responsiveness.
• Streaming Reduces buffering and improves video
  quality.
• Remote Work Enhances the quality of video calls
  and online collaboration.
