RAM on a computer

RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.

Laptop

A laptop, often called a notebook, or notebook computer, is a portable personal computer with a "clamshell" form factor, with a keyboard on the lower part of the "clamshell" and a thin LCD/LED computer screen on the upper portion, which is opened up to use the computer. Laptops are folded shut for transportation, and thus are suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, as of 2014, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia and home computer use.

Desktop computer

A desktop computer is a personal computer designed for regular use at a single location on or near a desk or table due to its size and power requirements. The most common configuration has a case that houses the power supply, motherboard (a printed circuit board with a microprocessor as the central processing unit, memory, bus, and other electronic component's), disk storage (usually one or more hard disk drives, optical disc drives, and in early models floppy disk drives); a keyboard and mouse for input; and computer monitor and printer for output. The case may be oriented horizontally and placed atop a desk or vertically and placed underneath or beside a desk.

Motherboard

A motherboard is the main printed circuit board (PCB) found in general purpose microcomputers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general purpose use.

Motherboard

Motherboard specifically refers to a PCB with expansion capability and as the name suggests, this board is often referred to as the "mother" of all components attached to it, which often include peripherals, interface cards, and daughtercards: sound cards, video cards, network cards, hard drives, or other forms of persistent storage; TV tuner cards, cards providing extra USB or FireWire slots and a variety of other custom components.

মাল্টিমিডিয়া

মাল্টিমিডিয়া বা Multimedia এমন একটি মাধ্যম যাতে বিভিন্ন ধরনের তথ্যকে (যেমন লিপি, শব্দ, চিত্র, এনিমেশন, ভিডিও প্রভৃতি) একত্রে দর্শক/ব্যবহারকারীদের কাছে উপস্থাপন করা হয়। মাল্টিমিডিয়া দিয়ে ইলেকট্রনিক মাধ্যমকেও বোঝানো হতে পারে যেটির মাধ্যমে মাল্টিমিডিয়া সম্পর্কিত তথ্য ধারন, সংরক্ষণ ও ব্যবহার করা হয়। শিল্পকলার মিশ্র শিল্পের সাথে মাল্টিমিডিয়ার অনেক মিল রয়েছে। "রিচ মিডিয়া" বা স্বয়ংসম্পূর্ণ মিডিয়া ইন্টারঅ্যাকটিভ মাল্টিমিডিয়ার আরেক নাম। মাল্টিমিডিয়া বলতে আসলে বোঝায় যে কম্পিউটারের তথ্যকে অডিও, গ্রাফিক্স, ছবি, ভিডিও ও এনিমেশন এবং এর সাথে লেখাও যুক্ত রেখে প্রকাশ করা যাবে।
