Estensioni della pagina Web - Explained By Semalt Expert

by
Feb 09, 2018

Prima di tutto, definiamo cos'è un tipo di file. È una specifica specifica (una delle tante) che descrive la struttura effettiva di un file. Secondo questa struttura, il file viene memorizzato, elaborato dai programmi e visualizzato. La parte visibile del tipo di file per un utente è l'estensione del file.

L'estensione del file è una sequenza specifica di caratteri (lettere e cifre), che segue il nome del file dopo il simbolo del punto "." e usato per identificare un tipo di file per programmi e utente. Vedendo l'estensione del file, la persona o il programma capisce quale tipo di dati è memorizzato in un particolare file, quali caratteristiche ha, cosa è necessario per eseguirlo.

Vale la pena notare che le estensioni di file di solito significano le caratteristiche di un certo file, non l'appartenenza di un file a nessun gruppo. Ad esempio, non tutte le immagini hanno la stessa estensione.

.html e .htm

HTML è un linguaggio di markup ipertestuale standard per i documenti che formano pagine web. I file scritti in html di solito hanno un'estensione auto-titolata.

.htm è un'estensione di file a volte usata per i file html.

La differenza tra .html e .htm è solo in una lettera mancante in un'estensione di file. In precedenza era dettata dalla necessità di limitare il numero di lettere nell'estensione del file: il vecchio sistema operativo poteva leggere solo tre simboli. Oggi non c'è una vera differenza.

.php

Un file con estensione .php è un file di testo con un codice di linguaggio PHP (Personal Home Page Tools). Il linguaggio PHP è ampiamente utilizzato per sviluppare applicazioni web e pagine web. Basato su file php, il server Web crea pagine Web dinamiche. Quindi, php-file è un programma scritto con PHP e .php è la sua estensione.

Immagini Web

Un'ampia popolarità per la grafica Web ha ricevuto due formati con estensioni dello stesso nome: GIF e JPEG. La loro multifunzionalità, versatilità, una piccola quantità di file sorgente di qualità sufficiente per una pagina Web è ciò che li ha resi uno standard per le immagini Web. C'è anche il formato PNG, che è anche supportato dai browser quando si aggiungono immagini. Tuttavia, la popolarità di PNG è molto inferiore ai formati GIF e JPEG.

GIF (Graphics Interchange Format) è un formato di file grafici ampiamente utilizzato durante la creazione di siti e la pubblicazione su pagine web. GIF utilizza colori a 8 bit e comprime in modo efficace intere aree di colore mantenendo i dettagli di un'immagine. GIF supporta una modifica delle immagini frame-by-frame che rende questo formato popolare per la creazione di banner e semplici animazioni.

JPEG (Joint Photographic Experts Group) è un altro formato popolare per le immagini Web. JPEG supporta i colori a 24 bit e mantiene inalterata la luminosità e le sfumature dei colori nelle foto. Questo formato è usato principalmente per le foto. Il formato JPEG può avere estensioni .jpeg e .jpg - come con .html e .htm, tutta la differenza è in una lettera mancante.

PNG (Portable Network Graphics) è simile a GIF. Secondo gli sviluppatori, PNG utilizza un formato migliorato per la compressione dei dati.

Quindi, per concludere, nella maggior parte dei casi i file .gif sono animazioni e immagini che richiedono una forte compressione e dimensioni ridotte, .jpg e .jpeg sono foto e i file .png sono tutto il resto.
