There had been many different types of computer storage devices available to us since the computer was invented. I have listed below and described the different types of computer storage devices that have been available in the market and have been used extensively since the 50s


Flash Disk

Flash disks are called with different names such as pen drive, USB drive, stick drive and more. These are external memory devices that allow one to copy and transfer data from one computer to another. Flash disks are evolving and getting faster then before. When Flash drive first came in the market, it had a very small storage capacity of 32 MB and now these are available with storage capacity of up to 2 TB (2000 GB)

Floppy Disk

These once were a very common type of storage devices for computers, in the 1970s until 1990s. Floppy disks could store only 1.44 MB of data. There were some larger capacity floppy disks that could store 2.5MB of data but these ones were not as common as the 1.44 MB ones.

Hard Disk

Hard disks are commonly used in computers today. This type of computer storage is available in the market with large storage capacities. The hard disk stores data on a magnetic disk and is very fast in reading and writing data from and to it. When hard disk was invented, it could only store 5MB of data. Today, the largest size hard disk that you can get has a huge storage capacity of 15 TB (15,000 GB)

SSD (solid state drive)


These are storage devices that contain flash memory chips to store data. Many modern laptops and desktop PCs now come with SSD instead of Hard disks because SSDs are much faster and also more durable. SSDs are also smaller in size than Hard Disks and also more expensive.

Memory Cards

  • SD (Secure Digital) card
  • Mini SD card
  • Micro SD card
  • MMC (Multimedia card)
  • xD Picture Card

These cards have different sizes and slightly different shapes and also come in different storage capacities. These memory cards are still being used extensively, specially the Micro SD card, it is commonly used in smart phones to extend the internal phone memory.

Compact Disks (CDs) and DVD (Digital Versatile Disk)

These are still used and and are available in the market. CDs can store data up to 700 MB and DVDs can store 4.7 GB of data in single-sided DVD and up to 17GB of data in double-sided DVD

Tape Drive

These were the cassettes that were so much common in the 1990s for playing music. These same tapes were also used to store computer data on them.

Cloud Storage

This refers to a storage which is located at a remote location, which is accessible to you through Internet. You might have used Google Drive, or One Drive or Drop Box. These all are examples of Cloud storages.

These are the different types of storage devices which have used in the past and we are using at present. The technology of computer storage has advanced so much. The same size of memory card that could store 64MB of data a few years back can now store 64 GB of data, this is really amazing. This is not it, the speed in which the memory sizes are increasing, we will soon be seeing too much more storage sizes that we can not imagine now.

In 1990s, the idea of connecting home alliances such as TV, fridge, heater, etc through Internet was promoted and commercialized. In year 2000, LG was the first company in the world to introduce the world’s first smart fridge. That fridge used the IoT (Internet of Things) technologies to allow you change the temperature inside the fridge from a mobile phone app, to alert you if the door was left opened accidentally and to do a number of more smart things like these. The product was not successful because people considered it to be overly prices and non-essential.

Smart Fridge Features

Today, smart fridges come with many different features and the list below mentions the best smart fridge features:

  • The smart fridge allows you to see inside your refrigerator from different angles.

  • You can track what you have in the fridge and what you need to buy at the grocery store.

  • Smart refrigerators can help you manage the expiry of products by sending you alerts about what should be thrown out.

  • Some smart fridges can automatically re-order products when their are finished or when less quantity is left, through online websites .

  • The fridge will ping you if you have left the door open.

  • Some smart fridges also work as an entertainment hub, allowing you to play music.

  • Some have digital planners that let you simplify and organize your daily routine.

  • Smart fridge contain technology that makes them more energy-efficient and cost-efficient.

  • Through the LCD panel on the smart fridge, you can access online recipes. You can either read the recipes yourself or have the fridge read them out to you.

  • The fridge will alert you when it needs maintenance.

  • Mobile app the comes with the fridge allow you to remotely change the temperature inside the fridge.


Advantages of Owning a Smart Fridge

A smart fridge in your kitchen will let you control your fridge and its content. You can monitor your food and cut down on food waste. You get the ability to know when food items are expiring. With the added LCD display, you add more fun in the house by displaying photos, playing music right from the fridge.

The smart fridge is a good choice for elderly and kids alike. Especially the disabled persons will find it useful by being able to remotely manage it and by having the fridge to look after the food and order the food itself for you.


Smart Fridges in Future 

In spite of the fact that many different smart fridges options are available in the market, there is still room for more advancements in the smart fridge technology and functions. The technology of smart fridges may even be expanded to detect the freshness of the stored food and also advise on meals that could be cooked with the items inside.

What is Internet of Things?

What is Internet of Things and what does IoT mean? IoT, short for Internet of Things means anything connected to the Internet to be operated remotely. So, the example of IoT could be your room light bulbs connected to a smartphone app through Internet so that you could turn the light on/off without needing to move to the on/off switch.

Using the Internet of Things technologies, we can connect virtually any electronic device to the Internet to be accessed and operated remotely. The concept of connecting electronic devices to the Internet is not very old and that is why we don't see and hear a lot (as of 2020) of IoT but work on IoT technology is happening very fast. Technology analysts predict that there will be around 40 billion connected IoT devices by the year 2025!

What are Different Uses of Internet of Things?

Transportation

The IoT technologies used in transportation, can assist in control, communication and processing of information. For example, IoT could be used for smart parking, smart traffic control, electronic toll collection systems, vehicle control.

Building construction


IoT devices can be used to monitor and control the electrical and mechanical infrastructure used in buildings, such as an elevator. IoT can also be used for real-time monitoring and controlling of energy consumption, and likewise there could be many other such IoT uses in home and building automation.

Military


Internet of Things can extensively be used for connecting vehicles, robots, sensors, equipment, human wearable and other technology that is used in military operations.

Agriculture

There could be a lot of uses of IoT in farming. This technology could be used for collecting data on rainfall, wind speed, soil quality, temperature. The collected data can then be used in making decisions, minimizing risks and wastes. IoT could even help using devices at farms to be controlled for the purpose of using spray, pumps and using other machinery remotely.

Manufacturing

IoT can help a lot in real-time optimization of manufacturing processes with the remote and automated use of sensors, control systems and other devices. The IoT can help for example in plant optimization, supply chain management, asset management, event management and likewise there could be many uses using IoT technologies.

Need of IoT

IoT is going to help us to be more efficient in how we do our routine tasks and save money and time also at the same time.  IoT has a lot of potential. It can get the tech companies, governments and people re-think how they should deliver and use services and products. In addition to allowing us to be more efficient to do things, the IoT will prove itself to be so much useful in elderly care, for the healthcare departments and for the physically or mentally impaired persons.

Having said and foreseen that, it can be said that very soon the world will become quite dependent on using Internet of Things devices, and even to the extend may be the use of the IoT devices in offices, homes, vehicles, planes and at every other place will be very common. Furthermore, we will find IoT devices available in our near electronic stores and these will be available at affordable prices - this era is very near!

Internet of Things Example of a Fridge

LG introduced in 1990 the world's first IoT fridge that you could operate remotely through Internet. There were a number of things the fridge owner could do using the fridge's IoT technology such as he would be notified if the inside fridge temperature is low and needs an increase. That fridge had other interesting features. Read about how IoT fridges are evolving and what features they currently have and will have in the near future. It's very interesting what an advanced IoT fridge could do. Read more about it here.
