The document outlines key emerging technologies of the 21st century, including blockchain, metaverse, artificial intelligence, edge computing, robotics, cyber security, digital immune systems, quantum computing, and sustainable technology. Each technology is defined and its significance in various sectors, such as industry and security, is highlighted. The conclusion emphasizes the profound impact of these technologies on simplifying and enhancing modern work processes.

1. INTRODUCING SOME
LATEST
TECHNOLOGIES
The twenty-first century has seen a technological revolution. Several highly commercial and
widely used technologies from the early 2000 have vanished, and in 2001 many last
technologies have emerged, particularly un the fields of computer science and engineering.
There are the top 10 emerging technologies of 2000.

2. A BLOCKCHAIN
 A blockchain is a distributed ledger with growing lists of records that are securely
linked together via cryptographic hashes. Each block contains a cryptographic
hash of the previous block, a timestamp and transaction data. A block chain ca be
seen as consisting of several layers e.g infrastructure, networking, consesus,
data, applications. It consists of public blockchain, private blockchain, hybrid
blockchain, side chains and consectium blockchain.

3. METAVERSE TECHNOLOGY
The term metaverse comes from the combination of two terms ‘meta’ meaning beyond and ‘verse’ meaning universe.
Metaverse technology can be defined as a combination of virtual realities existing over the internet. It is a virtual world that
consists of expirience, environment and entities over the internet. Big technologies have replicated the core notion of the
metaverse and offered a more mature 3D environment, which may provide individuals with an immersive digital
experience. It is now booming with more people becoming aware of it.

4. ARTIFICIAL INTELLIGENCE
 Artificial intelligence (AI) is intelligence exhibited by machines, particularly computer
system. AI technology is widely used throughout industry, government and science. The
growing use of artificial intelligence in the 21st century in influencing a social and
economic shift toward increased automation, data driven decision making. Professional
s in artificial intelligence create a programe machines to do human-like activities, it is
widely used to detect credit card fraud.

5. EDGE COMPUTING
 Edge computing is a distributed
computing model that computation
and data storage closer to the sources
of data, so that a user is likely to be
physical closer to a server. It might
use vitualization technology to simpley
deploying and managing various
applications on edge services. The
aim is to move the computation away
from data centres towards the edge of
the network, exploiting smart objects,
mobile phones.On the below is a
picture that shows an edge computing.

6. ROBOTICS
 Robotics is a field that studies and develops robots in order to make life easier. Robotics
is multi-disciplinary field includes computer science, electrical engineering and
machanical engineering. They are used to build cars, do dangerous activities such as
bomb dispersal and perform intricate procedures. This is how the robots looks like.

7. CYBER SECURITY
 Cyber security is concerned with preventing cyberthreats and attacks on computer
systems and networks, it is also a practice of defending computers, servers, mobile
devices and data from malicious attacks. It is aimed at accessing, changing or
destroying sensitive information, extorting money from users via ransom ware or
interrupting normal business.

8. DIGITAL IMMUNE SYSTEM
The concept of a digital immune system is a technology trends gaining traction in recent
years. It is a software based security systems, networks, and devices from cyber threats
such as viruses, malware and malicious software. It can be viewed as an analogy to the
human immune system, which helps the body against infection and diseases. It includes
various technologies such as firewalls, vulnerability scanners and intrusion detection.

9. QUANTUM COMPUTING
 Quantum computing is
an area of computer
science that uses the
principles of quantum
theory. It explains the
behavior of energy and
material on the atomic
and subatomiclevels. It
could contribute greatly
to the fields of security
and finance.

10. SUSTAINABLE
TECHNOLOGY
 Last but not least in today’s top
trending technologies is sustainable
technology, or “green tech”. As the
name suggests, it refers to
development and use of technology
that minimizes the negative impact on
the environment.

11. CONCLUSION
 Technology in computer science made
the system of work easy and short.
Above, the list of latest technologies in
computer science is a blessing of
modern science. We can do anything
short time by the use of this
technology.
