Session vs Viewstate in ASP.NET

What is the difference between SessionState and ViewState in ASP.NET?

If you asked this question to me, the main difference is a session known in a every page in all application and viewstate just only in a page. To know more about Understanding ASP.NET View State just read here . In stackoverflow, some people give their answer like this:

Session State contains information that is pertaining to a specific session (by a particular client/browser/machine) with the server. It’s a way to track what the user is doing on the site.. across multiple pages…amid the statelessness of the Web. e.g. the contents of a particular user’s shopping cart is session data.

Apa itu pseudocode?

Entah kenapa saya harus menuliskan ulang lagi dan memplejari hal mendasar ini karena pada beberapa saat lalu saya disuguhkan sebuah soal dengan membuat suatu pseudocode dari permasalahan yang ada. Jujur saya rada kewalahan menjawabnya karena lupa dan memang hampir tidak pernah menyentuh yang namanya pseudocode.

Memang rada sadis sih dan terlalu naif jika ditanyakan hal-hal seperti ini, pseudocode biasanya diajarkan pada awal belajar bahasa pemrograman yaitu di pelajaran algoritma dan pemrograman. Sepertinya saya salah dasar dulunya, terlalu banyak mengabaikan teori.
