A solid-state drive (SSD, also known as a solid-state disk) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently.

SSD technology primarily uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives (HDDs), which permit simple replacements in common applications.

Additionally, new I/O interfaces like SATA Express and M.2 have been designed to address specific requirements of the SSD technology.

Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit.

The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1.

Since even "nonconducting" transistors always leak a small amount, the capacitors will slowly discharge, and the information eventually fades unless the capacitor charge is refreshed periodically.

Because of this refresh requirement, it is a dynamic memory as opposed to static random-access memory (SRAM) and other static types of memory.

Unlike flash memory, DRAM is volatile memory (vs.

non-volatile memory), since it loses its data quickly when power is removed.

However, DRAM does exhibit limited data remanence.

A laptop, often called a notebook or "notebook computer", is a small, portable with a "clamshell" form factor, an alphanumeric keyboard on the lower part of the "clamshell" and a thin LCD or 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, Internet surfing using sites such as YouTube and for personal multimedia and home computer use.

In computing, an image scanner—often abbreviated to just scanner, although the term is ambiguous out of context (barcode scanner, CAT scanner etc)—is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image.

Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning.

Hand-held scanners, where the device is moved by hand, have evolved from text scanning "wands" to 3D scanners used for industrial design, reverse engineering, test and measurement, orthotics, gaming and other applications.

Mechanically driven scanners that move the document are typically used for large-format documents, where a flatbed design would be impractical.

In computing, memory refers to the computer hardware devices involved to store information for immediate use in a computer; it is synonymous with the term "primary storage".

Computer memory operates at a high speed, for example random-access memory (RAM), as a distinction from storage that provides slow-to-access program and data storage but offers higher capacities.

If needed, contents of the computer memory can be transferred to secondary storage, through a memory management technique called "virtual memory".

An archaic synonym for memory is store.
