Introduction to computer science (from beginning till now)

1) What is computer science

Computer science deals with the study of computers, computer systems, designing of computation using algorithms, and is their application in the processing of information by machines. It deals with the storage, retrieval, transmission and manipulation of data using programming, hardware, and intelligent systems. This discipline applies techniques and theories drawn from diverse fields such as mathematics, logic, engineering and computer science to enable the development of technology that defines the digital age.

It covers areas such as:

• Algorithms and data structures
• Languages of programming
• Databases and information systems
• Computer hardware and architecture
• Artificial intelligence and machine learning
• Networking and communication
• Cybersecurity and the digital systems

Computer science is the building block of the current technological era, and entities like Global Net Gen Academia enable students to grasp these ideas in a structured, easy way.

2) Why is computer science important in everyday life

With nearly every tool and service based on computational logic and digital processing, computer science has turned into an essential part of living every day. And it’s affecting even everyday activities like:

• On smartphones, laptops and tablets and the likes
• Send messages and make video calls
• Online banking, online shopping, and online payments
• Transit systems including GPS navigation
• Healthcare, including digital health records
• Smart home devices, automation and IoT solutions
• Social media, entertainment and online education

Nowadays today life, communication, work, and entertainment can’t do without computer science. Without it, modern systems like cloud computing, search engines, cybersecurity, or online education—including services offered by Global Net Gen Academia—would not exist.

3) Modern researches of computer science

Modern computer science research concentrates upon these emerging technologies for the future:

• Artificial Intelligence (AI) based decision making and automation
• Machine Learning and deep Learning based Predictions and Pattern Recognition
• Quantum computing for extremely fast and complicated calculations
• Blockchain for secure data transaction
• Robotics in industrial automation and medical application
• Augmented reality (AR) and virtual reality (VR) in experiential education
• Innovation in cybersecurity to guard all things digital
• Big data applications to big data processing
• Human–computer interaction (HCI) is work conducted at disseminating science to enhance user experiences

They are changing industry and research, and world communications.

4)How computer science came into existence

The development of computer science was gradual and was largely the result of the development of mathematics and engineering.

Key origins include:

• Ancient cultures employed counting rods and tally sticks
• Al-Khwarizmi, a Mathematician known as the father of Algebra also brought Algorithmic thinking
• 19th-century England: Charles Babbage (1791–1871) designs the Analytical Engine — the first mechanical computer
• Ada Lovelace – The first computer algorithm, the world’s first programmer

Following these were built by using electromechanical relays and then vacuum tubes in the mid-20th century.

New advances in computing such as programming languages, microchips, and networks shaped the contemporary computing era. By the end of the 20th century, computer science was an established academic discipline and is now taught worldwide, including through such digital learning platforms as Global Net Gen Academia.
