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. 1 bit = 0 /1 1 character = 8 bit 1 Kilobit (kb)= 1024 bit 1 Megabit (Mb) = 1024 Kilobit 1 Gigabit (Gb)= 1024 Mbit 1 Terabit (Tb)= 1024 Gbit 1 Petabit (Pb)= 1024 Tbit 1 Exabit (Eb)= 1024 Pbit “b” is the symbol of bit 1 bit = 0 /1 1 byte (B)= 8 bit 1 character = 8 bit = 1 byte 1 Kilobyte (KB)= 1024 B 1 Megabyte (MB) = 1024 KB 1 Gigabyte (GB)= 1024 MB 1 Terabyte (TB)= 1024 GB 1 Petabyte (PB)= 1024 TB 1 Exabyte (EB)= 1024 PB “B” is the symbol of Byte

4.  Questions  64 bit =..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.  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.  Write the factors can affect a speed of Internet?

8.  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
