<p> Sieci komputerowe s▒ to systemy komunikacyjne pozwalaj▒ce
na przesy│anie danych, miΩdzy dwoma lub wiΩcej po│▒czonymi komputerami
i urz▒dzeniami zewnΩtrznymi (np. drukarka). Typowa sieµ sk│ada siΩ z kabla
przy│▒czaj▒cego do sieci karty sieciowe znajduj▒ce siΩ w ka┐dym komputerze.
A po co w og≤le zak│adaµ sieµ? Korzy╢ci s▒ ogromne, do najwa┐niejszych
nale┐y zaliczyµ: wp≤│u┐ytkowanie program≤w, plik≤w i baz danych znajduj▒cych
siΩ na r≤┐nych komputerach, wsp≤│u┐ytkowanie zasob≤w sieci obejmuj▒cych
np. drukarki i pamiΩci masowe, szybka i │atwa komunikacja miΩdzy u┐ytkownikami,
mo┐liwo╢µ stworzenia grup roboczych umo┐liwiaj▒cych na prace nad danym
projektem osobom znajduj▒cym siΩ daleko od siebie czy te┐ wreszcie ograniczenie
wydatk≤w na zakup komputer≤w, poprzez mo┐liwo╢c korzystania z tanich,
bezdyskowych stacji roboczych przechowywuj▒cym dane na wsp≤lnym serwerze.
</p>
<p>Sieci dziel▒ siΩ na:</p>
<ul>
<li><span class="tekst"> <b>Sieci lokalne (LAN -local area network)</b>
- s▒ to po│▒czenia lokalne w ramach tej samej strefy np. budynku;<br>
