Description

Inventions in the electronic world have changed the course of our lives. Right from the laptops to the mobile phones we use,
These weren’t so simple and easy devices back in the days when they were first invented and brought in the market. From their bulky space consuming size to high complex operating mechanisms, these devices actually required you to be an engineer and smart guy before you had any of them. In this video we are about to look at some of the giant devices and inventions that could now fit inside your pocket.

Below is the featured list of the famous Electronic Inventions:


4. First RAM Computer

First RAM operated computer, developed by MIT Labs for the US Navy.
This computer was named, the Whirlwind project and the entire computer weighed for more than 20000 pounds.
It was the first computer to work in real time and even process the commands in parallel sequence instead of serial processing.
The project was directed by Jay Forrester, who discovered the first magnetic core memory that turned out to be the foundation random access storage, which we today call as the RAM.
The RAM in this computer had a total memory of 4KB.
The computer took 175 people that included 70 engineers and technicians to complete the entire project in 2 years of time span.
The computer could be used to solve equations and display its result on the oscilloscope.
The entire computer was designed using 5000 vacuum tubes which would generate huge amount of heat that made this computer even more difficult to operate.
The vacuum tubes were later replaced by transistors for reducing size and this laid the foundation of modern computers and the computers we use now.


3. First Mobile Phone

In 1983 Motorola introduced the first handheld mobile phone.
DynaTAC 8000x was the first commercial mobile phone that weighed around 2 kilograms, and costed a whopping $3995 US dollars in 1984 which is equivalent to around $9700 US dollars.
DynaTAC was an abbreviation for Dynamic Adaptive Total Area Coverage
In this price point, you can get 9 brand new iPhone XS Max in today’s date.
Also unlike the mobile phone that have become the entertainment and broadcasting stations for many of its users, DyanTAC 8000x was only able to call on any one of the numbers from the 30 stored in the recall system.
It had a small LED display for dialing, and its battery took around 10 hours to get fully charged, which provided a backup of 30 mins of talk time.


2. First Music Player

After the invention of Phonograph in 1877 by Thomas Edison, a device that was used to record and play music on cylinders.
But 10 years later, Emile Berliner patented the gramophone, which was the first commercial music player.
The gramophone was huge in size, and was used to record and play music on flat circular disk or records.
The first record was made from glass, which was later made by zinc and finally by plastic.
Before finally settling down to the tiny iPod and our mobile devices as our on the go music players, we made a large journey through some of the most gigantic music players to the ones which we have now.
After the gramophone came the LPs, then all through the cassette tapes to the optical disks we landed to the electronic music players and sharing systems such as Napster, against which the entire iPod and iTunes rolled up in the market.


1. First HDD

The first hard disk drive IBM 350 designed by IBM in 1953 weighed over a ton and stored a surprisingly small amount of only 3.75 MB of data.
This hard disk drive had 50 platters of 24 inches in diameter that were used to store data for the first time on magnetic circular platters.
The maximum average access time for data from this hard drive was 1 second.
Back in the time, a lot of other types of storage devices even made into the competition for the secondary storage, such as magnetic tape drives, drums, and floppy disks.
With a lot of revolutionary development and improvement for the hard drives, IBM finally made its first hard disk drive in 1980 that crossed the barrier of 1 GB.
This hard disk drive was called the IBM 3380, and could store 2.52GB of data and weighed around 250 kilograms which was encased in a cabinet of the size of your refrigerator now.
The first hard disk drive that was made available for the consumers in small compatible size was in 80’s which was 8 inches in size and could store around 5 MB of data.


So guys, which of these giant machines really amazed you?
Thanks for watching!
