Forth one is which one is fist programming language?

• The first programming language is Was Plankalkül By Konran Zuse

• This is simple program of Was Plankalkül … max from 3

• P1 max3 (V0[:8.0],V1[:8.0],V2[:8.0]) → R0[:8.0]
• max(V0[:8.0],V1[:8.0]) → Z1[:8.0]
• max(Z1[:8.0],V2[:8.0]) → R0[:8.0]
• END
• P2 max (V0[:8.0],V1[:8.0]) → R0[:8.0]
• V0[:8.0] → Z1[:8.0]
• (Z1[:8.0] < V1[:8.0]) → V1[:8.0] → Z1[:8.0]
• Z1[:8.0] → R0[:8.0]
• END

Fifth one who invent Disk operating System (DOS)?

• Means who invent DOS ?

Eight one is who invent Wi-Fi?
• The full form of wi-fi is wireless Fidelity and It invented by IEEE in 1997 named 801.11 with maximum speed is 2 mbps

• Why: because when need to product or launch the this facility than “IEEE 801.11” it not a technical and productive name and no easy to said than for product it called Wi-Fi.

• Version of Wi-Fi:
• 801.11a
• 801.11b
• 801.11n
• 801.11g
• 801.ac
• And after 801.11 a, 801.11 b,801.11 g, 801.11 n, 801.11ac now mostly use ‘n’ version with up to 1GB
• If frequency is more than speed will be increase but area will be decrease
• If frequency is less than speed will be decrease and area will be increase
• 1999 – 801.11a(for office, 5GHz 54mbps) and 801.b(for home, 2.3GHz 11mbps)
• 2003  - 801.11g = a+b (2.4 GHz, 54mbps)
• 2013 -801.11ac 5Ghz, 1.3GB
