Pentru ce este un router?<\/strong><\/p>\nUn router este prima linie de securitate de la intrarea \u00eentr-o re\u021bea. Activarea celui mai \u00eenalt nivel de securitate pe router este cea mai bun\u0103 modalitate de a v\u0103 men\u021bine sistemul \u0219i informa\u021biile \u00een siguran\u021b\u0103.<\/p>\n
Routoarele con\u021bin tip de software numit firmware care ar trebui s\u0103 fie actualizat \u00een momentul \u00een care apare o versiune nou\u0103.<\/p>\n
Cele mai multe routere se conecteaz\u0103 la alte dispozitive de re\u021bea numai prin intermediul cablurilor de re\u021bea \u0219i nu necesit\u0103 drivere pentru a func\u021biona \u00een Windows sau alte sisteme de operare. Cu toate acestea, routerele care se conecteaz\u0103 la un computer printr-o conexiune USB sau FireWire necesit\u0103 \u00een mod obi\u0219nuit drivere pentru a func\u021biona corect.<\/p>\n
Routoarele func\u021bioneaz\u0103 adesea ca servere DHCP \u00een re\u021bele mici, alocand adrese IP unice.<\/p>\n
Cele mai multe routere sunt produse de companii cum ar fi Linksys, 3Com, Belkin, D-Link, Motorola, TRENDnet \u0219i Cisco, \u00eens\u0103 exist\u0103 multe alte modele pe pia\u021b\u0103.<\/p>\n
Cum func\u021bioneaz\u0103 routerul<\/strong><\/p>\nRoutoarele conecteaz\u0103 un modem – cum ar fi un modem pe fibr\u0103, cablu sau DSL – la alte dispozitive pentru a permite comunicarea \u00eentre aceste dispozitive \u0219i Internet. Majoritatea routerelor, chiar \u0219i a routerelor wireless, au, de obicei, mai multe porturi fizice de re\u021bea pentru a conecta simultan numeroase dispozitive la Internet.<\/p>\n
De obicei, un router se conecteaz\u0103 fizic, printr-un cablu de re\u021bea, la modem prin portul „Internet” sau „WAN” \u0219i apoi fizic, din nou printr-un cablu de re\u021bea, la placa de re\u021bea, indiferent de dispozitivele de re\u021bea pe care le ave\u021bi. Un router wireless se poate conecta prin diferite standarde wireless la dispozitive care suport\u0103 de asemenea standardul utilizat.<\/p>\n
Adresa IP atribuit\u0103 conexiunii „WAN” sau „Internet” este o adres\u0103 IP public\u0103. Adresa IP atribuit\u0103 conexiunii „LAN” sau a re\u021belei locale este o adres\u0103 IP privat\u0103. Adresele IP private atribuite unui router sunt de obicei gateway-ul implicit pentru diferitele dispozitive din re\u021bea.<\/p>\n
Routerele wireless \u0219i cele cu fir care beneficieaz\u0103 de conexiuni multiple ac\u021bioneaz\u0103 de asemenea ca ni\u0219te switch-uri de re\u021bea simple care permit dispozitivelor s\u0103 comunice \u00eentre ele. De exemplu, mai multe computere conectate la un router pot fi configurate pentru a partaja imprimante \u0219i fi\u0219iere \u00eentre ele.<\/p>\n
Lucruri comune pe care le pute\u021bi face<\/strong><\/p>\nIat\u0103 c\u00e2teva set\u0103ri comune pe care le-a\u021bi putea face prin intermediul unui router:<\/p>\n
– Schimba\u021bi parola unui router<\/p>\n
– Configura\u021bi securitatea wireless pe un router<\/p>\n
– Actualiza\u021bi firmware-ul Router-ului<\/p>\n","protected":false},"excerpt":{"rendered":"
