Statistika

[Pavel Sedlacek]

Dobry den,

jsem v tomto listu novacek, takze prosim omluvte, pokud bude
tema meho dotazu mimo ramec teto diskuzni skupiny.

Nedavno se ke mne dostala nasledujici statistika:


>  As of Jan 97 there were over 1,000,000 web site names in use;
>  80,000,000 web pages we can reach without a password.
>
>  Based on what's out there: Typical page size is 5K, typical image
>  12K; median site size is 300 pages -- 50 sites have more than 30,000
>  pages.
>
>  "Typical" user  visits 20 PAGES (not sites)  per day.
>
>  The top 1000 web sites account for 1/2 the web traffic (out of top
>  300,000 sites).
>
>  Almost half (49%) of web users log on daily.
>
>  A survey in April/May of this year found 20% using 33.3 modems, 33%
>  using 28.8  and just 11% using 14.4. (That leaves 8% with faster
>  modems -- the majority [53%] are now 28.8/33.3). (6 months previous:
>  51% used 28.8, 20% used 14.4)
>
>  Research and e-mail are still the tops in internet usage, accounting
>  for 80% of activities by users.
>
>  As more and more folks get on-line, user demographics become more and
>  more like the "average" population.
>
>  In June, browser usage was: NN - 71%, IE - 14%, ISP Custom - 3%,
>  Other - 6%, "Don't know" - 6%. Total NN+IE= 85%.
>
>  Apache is still the leader in servers. MS, Netscape, NCSA and
>  O'Reilly are the also rans... Depending on how we look at it.
>  (1,200,000 servers on line July 97)  Apache holds 41% of
>  the web server market. Netscape is in second with about 13%, the
>  freeware NCSA server in third place at 12.63%, Microsoft in fourth
>  with 9.5%, and O'Reilly's WebSite in fifth with 3.77% of the servers
>  detected.
>
>  UNIX remains by far the dominant web server platform, but NT actually
>  has a dominant share when you consider only commercial servers.
>  Disregarding freeware servers and recasting Netcraft's figures for
>  commercial servers only,  Netscape holds about 40% market share,
>  Microsoft about 30%, and O'Reilly about 12%, with the remaining 18%
>  divided among several dozen other companies. Netscape reports that NT
>  makes up about half of their server sales; the Microsoft and O'Reilly
>  products run only on NT or Windows 95.

Cisla bude zrejme z hlediska celosvetoveho meritka brat s rezervou,
ale pro urcitou predstavu to staci.

Zajimalo by mne, kde najit podobne informace tykajici se pouze Ceske
Republiky.
