Khaled is coming to visit us on 13 June.

They came home while I was studying.

I wish I met you.

They look forward to receiving.

এখন সোয়া চারটা বাজে।

= Now, it is quarter past four.

Could you please pass me the salt.

সে খেলাধুলা ছাড়া কিছুই করত না।

= He did nothing but playing

ট্রেন আসার আগে আমরা স্টেশনে পৌঁছেছিলাম।

= We had reached the station before the train came

আয় বুঝে ব্যয় কর।

= Cut your coat according to your cloth

মশা স্থির জলে ডিম পাড়ে। 

= Mosquitoes lay their eggs in stagnant water.

A computer is an electronic device that processes data and performs various tasks according to a set of instructions known as programs. It consists of hardware components, such as the central processing unit (CPU), memory, storage devices, and input/output peripherals, which work together to execute operations efficiently. Computers are capable of performing a wide range of functions, from simple calculations to complex simulations and data analysis. They have revolutionized nearly every aspect of modern life, impacting fields such as education, business, healthcare, and entertainment. With the advent of the internet, computers have become essential tools for communication and information sharing, enabling people to connect globally and access vast amounts of knowledge at their fingertips. As technology continues to evolve, computers are becoming increasingly powerful and versatile, paving the way for innovations in artificial intelligence, machine learning, and beyond.

Knowledge become a possession as it is very personal when knowledge is acquired by giving own effort.

In an ideal system of education, teacher should encourage students to give labour to find out their dormant talents.

Training is better way than telling; because students' own faculties are things to be explored by a teacher.

The difference is that telling gives whether it is required or not and training guides what students can acquire.
