Which format is usually used to store data in computer ?

A BCD
B Decimal
C Hexadecimal
D Octal

Correct Answer: BCD

In BCD code, each decimal digit is represented by a 4 - bit binary number. যেহেতু কম্পিউটার বাইনারি পদ্ধতিতে কাজ করে থাকে তাই প্রশ্নে উল্লিখিত অপশনগুলোর মধ্যে BCD যুক্তিযুক্ত উত্তর। সাধারণভাবে একটি ডেসিমাল সংখ্যাকে বাইনারিতে রূপান্তর এর জন্য যে পদ্ধতি ব্যবহার করা হয় BCD - এর ক্ষেত্রেও সেই একই পদ্ধতি প্রযোজ্য। তবে মূল পার্থক্য হল, এখানে 4 - bit জায়গা সবসময়ের জন্য বরাদ্দ রাখতে হবে। অর্থাৎ প্রত্যেকটি সংখ্যা 4 - bit জায়গা নেবে। So, (592)10 = (010110010010)BCD
