Supercomputers

A supercomputer is pretty much exactly what it sounds like. It’s a term used to describe computers that have the most capable processing power of its time. Early supercomputers in the 60s and 70s used just a couple processors, while the 90s saw supercomputers with thousands of processors at a time. Today, modern supercomputers run hundreds of thousands of processors, capable of computing quadrillions of calculations in just a few nanoseconds. You probably won’t be needing that kind of power to access Facebook… Actually, supercomputers are used in computational science to calculate and carry out a plethora of complex tasks. Modeling molecular structures, weather forecasting, and the field of quantum mechanics, among others, rely on supercomputers and their intense processing power to solve their equations.

Mainframe Computers

Like supercomputers, mainframe computers are huge, towering machines with lots of processing power. Mainframe computers are mostly used by corporations, government agencies, and banks – organizations that need a way to store large quantities of information. They are not the same as supercomputers. The processing capabilities of mainframe computers are measured in MIPS, or millions of instructions per second. Supercomputers, on the other hand, are measured in FLOPS, or floating point operations per seconds.

Mobile Computers And Devices

These are exactly what they sound like – computers that are super small and mobile. You could argue that a desktop computer is mobile if you need it to be, but mobile computers usually describe computers that are meant to be carried around and taken from place to place. If a desktop computer is a microcomputer, then a laptop is a mobile computer. There are so many different types of mobile computers though, even beyond laptop-like devices. Below is a list of devices that could be categorized as mobile computers.

• Laptops: Portable computers designed to be carried from place to place. All of its components are contained inside a panel that functions also as the keyboard, with an attached screen that can be folded over. Because of their size and convenience, these are some of the most popular computers for everyday use. However, despite the convenience and ease of use, they aren’t without problems, as outlined in this guide to laptop problems and possible solutions.
• Netbooks: Much smaller laptops.
• Tablet: A flat, keyboard-less screen (though some of them come with keyboard attachments) that utilizes touch-screen functionality for navigation and use. Learn more about the history and function of tablet computers in this course.
• Handheld game console: Devices like the Game Boy, Game Boy Color, Game Boy Advance, Sega Nomad, PlayStation Portable (PSP), and PlayStation Vita are handheld game consoles. Just like regular consoles, these are tiny computers that let people play games on the go.
• Calculators: Calculators are computers that carry out computers’ most basic tasks – calculations! There are many different types of calculators. Basic calculators, graphic calculators, scientific calculators, programmable calculators, and calculators used for accounting and other financial purposes.
• Portable media players: Also known as MP3 players. That’s right – your iPod is a mobile computer too.
• Cellphones and smartphones: The iPhone and the Samsung Galaxy are examples of powerful smartphones that are also mobile computers. Thinking of getting a smartphone? Find the best smartphone for you with this detailed guide.

personal computer

a personal computer is a computer that can perform all its input,processing,output and storage 

activities by itself.there are two types of personal computers,desktop computers and netbook 

computers.The personal computers fits on a desk,the speed are various depends onthe 

 memory and processor.The storage is also various depends on the hard drive size     






      

embedded computer

Embedded computer is a special purpose computer that function as a component in a larger product and 

perform various functions depending on the computer.Some of the embedded computers designed to

 improve the safety,security and perfomance in today automobiles.Some examples of the embedded 

computers are in the consumer electronics,home automation devices,automobiles,and also computer devices 

and office machines.The physical size are small and the storage are also limited.The speed may slower than a mobile computer and devices
