  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
