Top 3 future technologies
Everyday new technologies are emerging with revolutionary innovations to address real world problems.
Here are Top 3 future technologies
1. Artificial Intelligence
2. 5G Network
3. Blockchain
1. Artificial Intelligence
 |
| Artificial Intelligence |
In 1955 John McCarthy introduced the word artificial intelligence and also invented the first programming language for symbolic computation, LISP and this language is still used as a preferred language in the field of AI. He was an American computer scientist. During one of his press conferences in 1956,he introduced this technology to the world . This is the reason why John McCarthy is known as the father of artificial intelligence.
Artificial Intelligence is an extended branch of computer science. Artificial intelligence is a variety of algorithms or computer programs and intelligence to try to behave and work like human intelligence. Here, Artificial means made by other human beings and intelligence means thinking power.
AI is a computer system capable of carrying out a task that typically asks for human intelligence. Without human effort, making machines that are capable of doing tasks and behave like human intelligence is the primary goal of artificial intelligence.
Examples of Artificial Intelligence
- Amazon's Alexa and Apple Siri, google assistant, echo.
- Google Maps and Speech recognition.
- Self- driving cars (Tesla) and email spam filters and so on.
Advantages of Artificial Intelligence
- Artificial intelligence helps us to reduce errors or bugs and increase the accuracy of work.
- Artificial intelligence gives us the freedom to make decisions quickly and complete our work rapidly.
- Artificial intelligence can make changes in the field of health , agriculture and security.
Disadvantages of Artificial Intelligence
- High cost of implementation and maintenance.
- Risk of unemployment .
2. 5G Network

| 5G network |
5G is a fifth generation wireless data network. 5G will enhance the speed of navigation for users far more than 4G Or 3G ever could. You will experience it in your phone, home and other places as well. 5G makes revolutionary changes in the speed of the network.
It is the next generation of mobile Broadband will ultimately substitute 4G LTE (Long-term evolution) connection. 5G provides faster download and upload speeds. 5G will offer download of 1 Gbps, that is relatively 100 times the present data speeds. It will provide multi-Gbps peak rate, massive capacity and a more smooth user experience.
The range of frequency will ensure no network blockage and provide more stable network connections.
Evolution from first generation to fifth generation
1G was initiated in the late 1980s and worked on analog radio signals (means it uses frequency modulation (FM) to encrypt a voice signal within a carrier wave) and supported only voice calls.
The second generation of wireless cellular technology (mobile telecommunication) was launched in the 1990s . 2G uses digital radio signals (means transferring and receiving sound processed into patterns of numbers) and it supports voice and data transmission with a bandwidth of 64 Kbps.
3G wireless cellular technology was launched in the 2000s . 3G has capacity to transmit telephone signals as well as digitized voice (it is a process of converting the analog signals to a digital signa) and video call and conferencing are also possible. 3G has a speed of 1 Mbps to 2 Mbps.
4G mobile telecommunication was launched in 2009. 4G was launched with the highest speed of 100 Mbps to 1Gbps and it also supported 3D virtual reality (computer -generated stimulation, for instance special goggles with a screen with sensors) .
Application of 5G
- The Internet of things is one of the revolutionary examples of 5G.
- High-speed mobile network which will give us the experience of better navigation and surfing.
- Telecommunication services will be better with 5G networks.
Advantages of 5G
- High data speed of fifth generation networks can assist cloud systems to stream software updates and navigation of data.
- It will also help to integrate artificial intelligence in our daily lives.
Disadvantages of 5G
- Infrastructure development of 5G is very expensive. It is impossible to take off without basic infrastructure foundation, such as usual servers and open application programming interface (APIs) and so on.
- Large number of old devices will be necessary to substitute as they are not supporting 5G.
3. Blockchain

| Blockchain |
Blockchain research began in the late 1990s but was actually implemented in 2009. An anonymous developer named Satoshi Nakamoto created Bitcoin with the help of blockchain. And the world started witnessing the boom of Cryptocurrency.
Before we jump into the blockchain we have to understand what a database actually is. A database is a collection of information and information can be anything like our images, texts and it is stored in our computers system electrically.
Storage structure
Blockchain is a special kind of database which is different from our regular database. Like our typical database stores information but blockchain stores data into the blocks and they are chained together and this is the reason we called it blockchain. Blocks have particular storage capacity and when the storage capacity reaches to the maximum then it is chained into the previous block, which makes the data chained together in chronological manner.
Advantages of Blockchain
- Secure - For the reason that it is an open source ledger, each and every transaction is made public means we all can see it . Which means there are no loopholes for fraud .
- No third party interference - Like our regular database which has authority can make changes in the database that is not reliable whereas in blockchain there is no individual authority , no government or financial Institutions has command on the Cryptocurrencies based on blockchain.
- Secure transaction - it's nearly impossible to make changes in the transaction history of blockchain unlike our regular database. This makes the online transaction safe and secure.
- Instant transaction - As our regular transactions that we usually do with different bank accounts takes a lot of time but this is not the case with blockchain it takes only a few minutes to complete transactions.
Disadvantages of Blockchain
- Data is immutable - one of the biggest disadvantages of blockchain is data Immutability.
- Cost and implementation - Blockchain implementation is very expensive . The maintenance cost is also high.
- Not completely secure - We can consider that blockchain technology is secure as compared to other platforms but not fully secure. There are various attacks which make it not fully secure for example D-Dos attack , cryptographic cracking, 51% attack and so on.
