Naamini kwa kutoka kwenu kwenye mada ya Sudan na kuingia kwenye Uislamu lile suala limeeleweka kuwa Sudan matatizo yaliyopo ni ya kuletwa na ya kubuniwa.
Sasa wacha tuone uzuri wa uislamu kwa kuangalia jinsi ulivyopelekea kuvumbuliwa internet.
Kwanza tuelewe kuwa kifaa muhimu cha upatikanaji wa internet ni compyuter.
Moja ya makampuni makubwa ya kutengeneza compyuter ni IBM.Wao wakitoa historia ya kuundwa kompyuter wanasema:
Drum Memory
The IBM 650 used a drum memory organized into signed, ten-digit decimal words. The basic '650 had 2000 words of memory. You could add additional drums for up to 10,000 words. [Tom Zaslavsky remembers 6,000 max.] Jonathan Baker tells us there were 200 read/write heads with 50 words per set of 5 heads[SIZE=+1].[/SIZE] A later option added 60 words of core memory where you could store fast loops.
Each word could represent a signed decimal integer or an instruction. There was an optional floating point unit with an eight-digit signed mantissa and a two digit exponent biased by 50.
Each digit was represented in seven bit "bi-quinary" notation: one bit out of 5 represented a value from zero to four; one bit out of two indicated whether or not to add 5 to that value, essentially an electronic abacus. The front panel had rows of lights in groups of five to display register contents. "28019" would be displayed as follows:

[SIZE=-1]*[/SIZE][SIZE=-1] 9[/SIZE]Actual displays were 10 digits long, with the sign on the right side, just 2 lights in the same space as a full digit. The console layout is per[SIZE=+1] [/SIZE]Jonathan Baker[SIZE=+1]'[/SIZE]s correction to my original posting. His other comments appear below.
An IBM 650 instruction looked like this:
xx yyyy zzzz
Hapo angalia maneno kama zero,decimal,light.Angalia na herufi za kutoa kanuni ya makisio xx yyyy zzzz.
