Xulosa
Bu kurs ishimavzusida SMTP protokoli asosida tarmoq dasturini tuzish, electron pochta va SMTP protokollari haqida ma’lumotlarga ega bo’lindi. Bunda keltirilgan dasturda proyekt oynasi xosil qilindi. Proyekt oynasida MAIL adresi, Parol, Jo’natuvchi, Qabul qiluvchi, Title, Text va Send maydonlari mavjud. Biz proyekt oynasining MAIL adresi, Parol, Jo’natuvchi, Qabul qiluvchi maydonlariga kerakli adresslarni kiritamiz, oynaning Title qismiga “Salom” so’zi kiritilgan. Text qismiga xam ma’lumotlarniyozib Send tugmasiorqali jo’natishimiz mumkin bo’ladi.
Elektron pochta ko‘p tomonlama oddiy pochta xizmatiga o‘xshab ketadi. Xabarlar foydalanuvchi tomonidan kompyuter ishchi stolidagi dastur yordamida, matnli redaktor yordamida yoki veb brauzer yordamida tayyorlanadi. Keyin foydalanuvchi elektron pochtani yuborish dasturi chaqiriladi.
Elektron pochta – ro‘yxatga olingan adreslar o‘rtasida xabarlar almashish xizmati hisoblanadi. Dastlab elektron pochta haqida gapirilganda matnli ma’lumotlarni jo‘natish tushuniladi. Xabarlarni raqamli ko‘rinishda tasvirlash uchun ASCII kodlash tizimi qo‘llaniladi. Unda kodlashda xar bir simvol uchun 8 bit ishlatiladi.
Elektron pochta adresi quyidagi ko‘rinishda bo‘ladi:
[e-mail], [e-mail]
Bu yerda, pochta.domen – domen nomi, elektronpochta – foydalanuvchi ismi, identifikatori. Pochta adresi bitta odamga, guruxga yoki tashkilotga tegishli bo‘lishi mumkin.
