From Punch Cards to Cloud How Data Storage and Processing Have Evolved Over the Years!

Data scientist course in Delhi

We cannot imagine leading our daily life without the internet. But have you ever realized that the internet is nothing but a world of data! Whatever we do on the internet is nothing but accessing, sharing, and storing data- write mails, share information, social networking, financial transactions, blogging, streaming videos and doing business, etc all that is related to data transfer and nothing else. Accessing, storing, and processing data is indispensable to us in this age. But one might wonder where did we start?

The age of punch cards 

Punch card is the first official form of data storage. It was basically a stiff paper where wholes were punched sequentially on predefined positions. The data could be read by machines on the basis of the presence or absence of the wholes. 

Later in the 1890s, the Hollerith card developed by Herman Hollerith became famous as punch-card data processing technology was introduced. The punch cards continued to be developed and were used even in the 1960s!

Magnetic tapes

During the mid-1970s magnetic tapes became popular digital data storage devices. However, such tapes were first used in 1951 and IBM utilized this technology since the 1950s. The tapes basically were coated with magnetic material and data was recorded sequentially on tracks. 

The development of magnetic storage devices was a huge boost for the field of computer science and digital technology as a large amount of data could be stored and even now the technology is widely used for archives. However, it has several disadvantages such as slow reading and writing speed and loss of data due to the weakening of the magnetic field of the tapes! 

Floppy disks, CDs and DVDs 

While the need for internal storage was being satisfied with the different kinds of magnetic tapes, soon external data storage devices became extremely important as individuals wanted to ‘carry’ important bits of data for a variety of reasons. The disk storage technology for storing and carrying bits of data 1st appeared in the 1970s and termed as floppy disks. 

Another revolutionary form of data storage appeared in the form of optical storage devices such as CDs and DVDs. One important advantage of CDs and DVDs was that fact that those could carry Hundreds of MBs and even multiple GBs later as development progressed!

The advent of the cloud! 

As the internet was quickly gaining popularity in the late 1990s and early 2000s, it was very apparent that soon we will have to increase our database storage and processing capacity. Soon it was clear that there is a necessity for storing large amounts of data at a place where it could be accessed from anywhere with efficiency and also at a low cost. The answer was cloud storage! 

Interestingly cloud storage shares its history with the ARPANET which is also the forefather of today’s internet. The concept of ‘cloud’ is actually more than just storage, it brings together computing resources like networking, analytics, services, and intelligence. This concept is also as old as the internet but only gain popularity over the last decade. Today’s businesses and organizations find it inefficient to manage and manipulate data over physical storage devices and the cloud is just the thing they needed. The servers or physical units of the cloud encompasses several devices and computer systems all connected via the internet, thus allowing data storage, access and processing on a large scale in a very efficient manner! 

How much data you are wondering? Well, today more than 1exabytes of data is stored in the cloud!

Why do we put so much emphasis on data storage and processing? 

The reason we put so much emphasis on data storage and device is the fact that over the years the value of digital data has become significantly high. Today, businesses and organizations can use data as an important resource for a variety of purposes like growth, discovery, revenue, and even sell thanks to data science!

The field of data science is now brimming with possibilities and now that major economies are going completely digital, data is now much more important. India too aims to transform its economy into a completely digitalized industrial sector. Interestingly, this can be a great opportunity for you to decide on a lucrative career as data science is one of the most lucrative career fields out there. If you have a knack for computer systems, data and analytics then you should go for an affordable Data scientist course in Delhi, the capital of India which is also quickly becoming a data science hub!
