Which one of the following is a read only memory storage device? Correct Answer CD-ROM

Read Only কথার অর্থ হল কোন তথ্য শুধুমাত্র ব্যবহার করা যাবে কিন্তু সেটি পরিবর্তন বা নতুন তথ্য যোগ করা যাবে না। অর্থাৎ চারটি অপশন এর মধ্যে শুধুমাত্র CD - এর মধ্যে সংরক্ষিত তথ্য আমরা ব্যবহার করতে পারি কিন্তু এগুলো পরিবর্তন করা যায় না। (যদিও CD এর তথ্য প্রযোজ্যক্ষেত্রে পরিবর্তন করা যায় এবং বর্তমানে এর ব্যবহার নেই বললেই চলে) অন্য অপশন গুলোঃ হার্ডডিক্স, পেনড্রাইভ এবং ফ্লপি ডিস্ক এর তথ্য পরিবর্তন করা যায়।
