ไฟล์คอมพิวเตอร์ก็มีนามสกุล ซึ่งจะบอกถึงประเภทของไฟล์นั้นๆว่าเป็นไฟล์รูปภาพ ไฟล์ภาพยนต์ หรืออะไรอีกตั้งมากมายไม่แพ้นามสกุลของคนเลย
คงสงสัยละสิว่าเราจะรู้ได้อย่างไรว่าไฟล์นั้นนามสกุลอะไร ดูง่ายๆคือ ชื่อไฟล์.นามสกุล
แล้วประโยชน์อะไรที่ต้องรูปจักชื่อไฟล์ใช่ไหมครับ เมื่อเรารู้นามสกุลเราก็จะรู้ได้ว่าไฟล์นั้นจะถูกเปิดได้ด้วยโปรแกรมอะไรสิครับ
