2. About Tech Industry
Introduction: Imagine a world where
boundaries are constantly pushed and
possibilities are endless—that's the
essence of the technology industry.
From the magic of software
development to the wonders of
computer hardware, electronics, internet
services, artificial intelligence, and
telecommunications, this sector thrives
on innovation and research.
It's not just an industry; it's the heartbeat
of global progress, reshaping our
communication, work, and daily lives.

3. 1950 to 1970 Tech - Foundations of Modern Computing
Software Innovations: The era from 1950 to 1970 saw the programming languages
such as FORTRAN (1957) and COBOL (1959), which significantly simplified computer
programming.
Hardware Advancements: This period was marked by the invention of the integrated
circuit in 1958, a breakthrough that miniaturized electronic components and paved the
way for modern computers. The IBM System/360, introduced.
Networking Breakthroughs: Networking took a giant leap forward with the
development of ARPANET in 1969, the precursor to the internet, based on the novel
concept of packet switching introduced in the early 1960s.
Storage Evolution: significant advancements with the introduction of magnetic tape
and disk storage, which dramatically increased data storage capacities and access
speeds.
UI Developments: In terms of user interface, the 1960s introduced the computer
mouse and graphical user interface (GUI), revolutionizing the way users interact with
computers.

4. 1970 to 1990 Tech - Birth of Personal Computing and Networking
Software: creation of the UNIX OS in 1969. The first relational database management system
(RDBMS), Oracle, was launched in 1979. The programming languages C (1972) and C++ (1983).
Hardware: In hardware, the Intel 4004, the world's first microprocessor, was released in 1971,
paving the way for personal computing. Apple introduced the Apple II in 1977, s. The 1980s saw
the emergence of the IBM PC, which standardized the architecture for personal computers.
Networking: the development of the TCP/IP protocol in the 1980s, laying the foundation for the
modern Internet. The first email was sent in 1971, and the domain name system (DNS) was
introduced in 1984.
Storage: introduction of the floppy disk in the early 1970s, followed by the hard disk drive (HDD)
becoming a standard in personal computing. The CD-ROM, introduced in the mid-1980s,
.
UI: 1980s were marked by the advent of graphical user interfaces (GUIs), with the Xerox Alto and
the Apple Lisa being pioneers. The introduction of Windows 1.0 by Microsoft in 1985 brought
GUIs to a broader audience.

5. 1990 to 2010 Tech - The Internet, Mobile and Social Media Revolution
Software: he birth of the www/World Wide Web, making the internet accessible to the
masses. This era also witnessed the dominance of Windows 95, and open-source
platforms like Linux. Web Browser in 1990 open the doors and Search engines like
Google redefined how we find information, while Adobe Flash enabled rich multimedia
content online.
Hardware: personal computers, becoming more powerful and affordable. The
introduction of USB technology simplified the connection of devices. Mobile phones
transformed into smartphones, with Apple's iPhone setting a new standard for mobile
computing and communication.
Networking: the transition from dial-up to broadband internet, drastically improving
online speed and connectivity. Wi-Fi became widespread, offering wireless access to
the internet, marking a significant step towards global connectivity.
Storage: a shift from floppy disks to CDs, DVDs, and eventually to USB flash drives for
data storage and transfer. The development of Solid State Drives (SSDs) provided
faster, more reliable storage solutions, significantly.
User Interface (UI): Touchscreen technology, popularized by smartphones and tablets,
further revolutionized user interaction, making computing more intuitive and user-
friendly.

6. 2010 to till now Tech - Cloud, IOT, Blockchain and AI
Software: The rise of Cloud (Private, public and Hybrid) by AWS, Azure and Google.
IOT device connectivity, BlockChain architecture (Bitcoin, ..), artificial intelligence (AI)
and machine learning (ML) algorithms.
Hardware: More powerful and energy-efficient processors by companies like Intel and
AMD, along with advancements in quantum computing, have pushed computational
boundaries. The proliferation of IoT devices has led to smarter homes and cities,
enhancing daily life through connectivity and real-time data.
Networking: rollout of 5G technology, offering significantly faster data speeds and
lower latency. This has enabled the growth of mobile internet, IoT, and edge
computing, transforming how devices communicate and process information.
Storage: the advent of solid-state drives (SSDs) becoming mainstream, offering faster
access times and reliability over traditional hard drives. Cloud storage solutions have
also become ubiquitous, providing flexible and scalable data storage options for
individuals and businesses alike.
UI/UX: Advancements in Touch Screen and the integration of voice and gesture
controls has further enhanced interactive experiences, making technology more
intuitive and user-friendly.
