Daniela: Memory is any physical device capable of storing information temporarily or permanently

Luciana: Example: RAM (Random Access Memory)
volatile memory that stores information on a circuit used by the operating system, software and hardware

Moni: Memory can be either volatile and non-volatile memory. Volatile memory is a memory that loses its contents when the computer or hardware device loses power

Daniela: Non-volatile memory (VRAM) is a memory that keeps its contents even if the power is lost.

Jesus: This is an example picture of a 512MB DIMM computer memory which connects the memory slot on a computer

Mónica: Any type of computer hardware that is used for storing, porting and extracting data files. It can store information in two ways, temporarily and permanently. There are many types of memories that serve as storage devices, there can be other devices or USB's that are great for transportation of virtual documents and files.

Luciana: Also it can variate into being internal or external in a computer a server or any similar device. It changes variating in the type of storage device. A CD for example is external and can be extracted from the computer also storing information, this one can have the information for the amount of time the user prefers.

Dany: It's also one of the core components of a computing device, their function is to store virtually all the data of a computer excluding hardware firmware.  A great example of it is a USB since it stores virtually the information.

Jesus: There are two different storage devices: Primary which is smaller in size  and it's design to store temporary information and Secondary that is contrary to the primary storage device. For example, a USB can save information temporarily while the HDD can save permanently.

Examples: CD, HDD, USB

Moni: An imput device is formed by components that allow the data and instructions enter the computer.
Dany: One example is the keyboard, it can do specific functions like deleting, inserting or adding text between other functions.
Luciana: The pointer (mouse), allows the control of the screen-based systems since it controls the cursor to interact with different options, programs, information or files.
Jesus: A microphone is an audio input that can be either be previously installed on a computer or can be connected externally on a port. The microphone can send data to the computer in the shape of digital signals.

Luciana: Any device or piece or hardware, used by humans with the purpose of sending data from a computer, in unreadable form to another, which is readable by humans.
Daniela: Examples: Some examples, which are used in the daily life include, headphones, projectors, speakers, monitors and printers.
Jesus:
Headphones: An example of an output device is a set of headphones. They work by transporting the music through a wire and ending this vibration in the middle ear for humans to hear.
Moni:
Speakers:  Another example are the speakers. They work by becoming an electromagnent and pumping sound waves into the air.
Printers: Another example are printers, they work with lasers by scanning inside of static electricity. It attracts the toner and prints.
