Understanding Digital Data Size and Internet Velocity

This document explores the foundational concepts of digital data size, defining bits, bytes, and larger units, while illustrating their relationships through characters and binary representations. It poses questions regarding the size and conversion of data units, such as kilobytes, megabytes, and gigabytes. Additionally, it discusses the formula for calculating internet speed based on data size and download time, highlighting factors that influence this velocity, including hardware, software, and external traffic. An interactive example of calculating ISP speed is provided for practical understanding.

  1. Size of Digital Data And Velocity Internet By Dzuryat Nugroho

  2. Bit • The smallest size of data in computer 1 bit = 0 or 1 • Character (a,b,c,d……z,1,2,3,&,%,?,/….) • 1 character = 8 bit • So,…if we have “A” = 00110011 “b” = 11001100 “c” = 10101010

  3. Size of data

  4. Questions • 64bit = ..8.? karakter • 5 karakter = ..40..? bit • 6 byte = ..48..bit • 240 bit = ..30.byte? • 5 Kilobyte = .5 x 1024..= 5120.?byte • = ....? bit • 4 Megabyte = 4 x 1024x1024....? byte • = .....? bit • 4 Gigabyte = .4x1024x1024x1024.....? byte • = .....? bit

  5. The Formula of Speed Data Internet • V = Velocity (Kb/s) • S = Size of data (Kb) • t = time (second)

  6. Question : You’re downloading a file in ICT laboratory. The size of data is 2 MB. You can complete in 5 minutes. How much ISP speed do you use?

  7. Disscusion • Write the factors can affect a speed of Internet?

  8. Internet Speed Factors : • Internal • Modem • PC (Personal Computer) • The line telephone quality • Software/ program that is used • Eksternal • The number of site visitor • The number of ISP (Internet Service Provider) visitor • Server access speed
