QU\u00c8 \u00c9S UN SERVIDOR?<\/h2>\n\n\n
\n
\"\"<\/figure>\n<\/div>\n\n\n

Un servidor \u00e9s un equip inform\u00e0tic o un ordinador d'alta capacitat i pot\u00e8ncia encarregat d'emmagatzemar informaci\u00f3. Aquest ordinador forma part d'una xarxa on altres ordinadors tenen acc\u00e9s a la informaci\u00f3 emmagatzemada. La finalitat \u00e9s que els ordinadors connectats al servidor tinguin la informaci\u00f3 a la vostra disposici\u00f3.<\/p>\n\n\n\n

Les m\u00e0quines servidores tenen m\u00e9s capacitat demmagatzematge i de mem\u00f2ria que el que sol tenir un ordinador, aix\u00f2 \u00e9s degut al servei que han de donar a m\u00faltiples ordinadors. Normalment els servidors es troben a empreses, centralitzant i emmagatzemant aix\u00ed la gran quantitat de dades que es generen.<\/p>\n\n\n\n

Components d'un servidor<\/strong><\/p>\n\n\n\n

    \n
  • Sistema operatiu: <\/strong>Programari que s'encarrega dels processos b\u00e0sics d'un ordinador i facilita el funcionament d'altres programes<\/li>\n\n\n\n
  • Font d'alimentaci\u00f3: <\/strong>Dispositiu que alimenta els components interns i que permet que el servidor estigui enc\u00e8s les 24 hores.<\/li>\n\n\n\n
  • Disc dur: <\/strong>Component que emmagatzema els programes i la informaci\u00f3 del servidor, la seva capacitat normalment \u00e9s de diversos terabytes.<\/li>\n\n\n\n
  • Processador: <\/strong>Eina que ajuda a processar les dades i programes, es troben diversos dins del servidor a causa de la gran quantitat dinformaci\u00f3 que semmagatzema a lordinador.<\/li>\n\n\n\n
  • Mem\u00f2ria RAM: <\/strong>Sistema d'emmagatzematge que guarda informaci\u00f3 temporalment perqu\u00e8 l'ordinador pugui realitzar les seves funcions, en cas que s'ompli aquesta mem\u00f2ria s'utilitza la mem\u00f2ria del disc dur, fet que suposa uns processos m\u00e9s lents.<\/li>\n\n\n\n
  • Lector de CD o DVD: <\/strong>Permet la reproducci\u00f3 tant com de CD com de DVD<\/li>\n\n\n\n
  • Plaques de sistema: <\/strong>Mantenir connectats els diferents components del servidor.<\/li>\n<\/ul>\n\n\n\n

    Tipus de servidors<\/strong><\/h2>\n\n\n\n

    Servidor de correu<\/strong><\/h3>\n\n\n\n

    Permet gestionar les operacions relacionades amb el correu electr\u00f2nic. Envia, rep i desa la informaci\u00f3. Facilita la comunicaci\u00f3 entre els usuaris i que la transmissi\u00f3 de dades sigui m\u00e9s efica\u00e7.<\/p>\n\n\n\n

    Servidor Proxy<\/strong><\/h3>\n\n\n\n

    Equip que fa d'intermediari entre dos sistemes, impedeix les connexions directes entre emissor i receptor, actuant com a filtre de seguretat. El servidor intermediari pot estar dins un firewall i tamb\u00e9 est\u00e0 disponible de manera independent.<\/p>\n\n\n\n

    Servidor Web<\/strong><\/h3>\n\n\n\n

    La seva funci\u00f3 \u00e9s emmagatzemar fitxers (HTML, imatges, fulls estil CSS i documents JavaScript) d'un lloc per emetre'ls i els usuaris el puguin visualitzar. Quan el navegador informa que necessita un fitxer desat al servidor web, ho demana mitjan\u00e7ant HTTP, una vegada arriba al servidor el servidor HTTP envia la informaci\u00f3 sol\u00b7licitada.<\/p>\n\n\n\n

    Servidor de base de dades<\/strong><\/h3>\n\n\n\n

    Emmagatzema, gestiona i recupera dades. Facilita i agilitza l'administraci\u00f3 de les dades emmagatzemades perqu\u00e8 permet configurar l'acc\u00e9s a usuaris, importar o exportar dades.<\/p>\n\n\n\n

    Servidors dedicats<\/strong><\/h3>\n\n\n\n

    \u00c9s un equip comprat o llogat el qual sutilitza el servidor complet per part duna companyia, tenint un control total del servidor. Normalment es troben en centres de dades on un sol client contracta el servei o adquireix la maquin\u00e0ria amb la finalitat de disposar de tots els recursos.<\/p>\n\n\n\n

    Servidors d'imatges<\/strong><\/h3>\n\n\n\n

    Servidors dedicats a les imatges o fotografies on les persones poden emmagatzemar les imatges. Tamb\u00e9 permet importar o exportar i fins i tot recuperar-los en cas de p\u00e8rdua.<\/p>","protected":false},"excerpt":{"rendered":"
