iOS Architecture - Layers

iOS ka architecture kuch aise layers mein bata hua hai:

1) Cocoa Touch Layer: Yeh top-most layer hai jo UI components, multi-touch aur inputs/outputs handle karta hai. Yahan frameworks hain jo app development aur user experience design ke liye help karte hain.

2) Media Layer: Audio, video, graphics aur animation ke liye technologies issi layer mein hain. QuickTime, OpenGL aur Core Animation jaisi cheezein isme aati hain.

3) Core Services Layer: Yeh layer fundamentals provide karta hai - file management, iCloud support, Grand Central Dispatch aur security/privacy features. iOS ki core functionalities yahaan se aati hain.

4) Core OS Layer: Sab se neeche ka layer hai, jisme low-level services aur technologies hain jaisa ki networking, power management, external accessory support etc. Kernel, filesystems, secure boot aur low-level utilities bhi yahaan hain.

Disadvantages/Limitations of iOS

Closed System

iOS ka closed system khud ek limitation hai. Code fully closed source hai aur Apple strictly regulate karta hai apps aur customizations. User kuch zyaada flexibility nahi rakhta hai.

Costly Devices 

iOS sirf Apple branded devices (iPhone/iPad) pe chalta hai aur yeh costly hote hain. Affordable options (jaise Android phones) isme nahi milte.

Limited Customization

Jab tak customization baat hai, iOS mein Andoid jitni flexibility nahi milti. Bahut zyaada GUI/app icon changes ya extensive tweaks nahi kiye ja sakte hain.

Limited External Storage

Ek aur limitation hai limited external storage. MicroSD cards ka use nahi kiya ja sakta hai aur built-in storage jab khatam ho jaaye toh expand karna mushkil hai.

Parakhne Par

iOS apps ke saath smooth, seamless aur secure experience milti hai. Lekin developer productivity aur flexibility baaki mobile OS jaisi nahi hai. Saath hi kuch costly bhi hai.

Phir bhi, agar aap high performance, eye-catching designs aur consistent updates chaahte hain, toh iOS ek acchi choice hai. Yeh premium devices keliye banaaya gaya hai aur use karna bahut easy rahega agar aap Apple ke ecosystem mein pehle se hi invested hai.
