There are a few other components that e-writers share with one another. The brain of the e-writer is a microprocessor that executes operations on data. An operation may be as simple as sending a scribbled note to memory so that you can retrieve it later. Or it may involve executing complex algorithms to translate chicken scratch into text.
An algorithm is a mathematical set of directions. Handwriting-recognition algorithms analyze the motions you make on the touch-screen interface and attempt to match them to letters. Depending upon the algorithm's sophistication, it may be able to interpret both print and cursive writing. Paired with word-recognition software, the algorithm may be able to make a best guess at what you were writing and complete a word even if you don't dot every i and cross every t.
The type of microprocessor in an e-writer varies on the make, model and manufacturer. Important features in a mobile device microprocessor include a compact design and high efficiency. As microprocessors do work, they generate heat. Too much heat can cause electronics to malfunction. Efficient microprocessors generate as little heat as possible while still providing a satisfactory experience.
Another part of the e-writer's brain is its memory. Solid-state memory chips, also known as flash-memory chips, provide storage for mobile devices. When you write something on an e-writer and save it, the processor sends the data in a series of bits -- zeros and ones -- to storage. Some e-writers may allow you to use removable memory cards, increasing the amount of storage at your disposal.
The third component you'll find in most e-writers is a battery. An e-writer's battery life depends on many factors, including the type of processor it has, the type of touch-screen interface it uses and other components.
Several other features may be included, depending upon the e-writer. Some may feature full-color displays rather than monochromatic ones. You can find e-writers with WiFi connectivity and biometric components. Some e-writers may seem more like fully fledged tablets than dedicated writing devices. The definitions for e-writers, smartphones, tablets and related mobile devices aren't rigid. E-writers might never become a successful, distinct product category. Instead, the e-writer functions may become part of other, more established categories of electronics.
