Computer and Internet

Computer and Internet

Computers and the internet enable access to cloud resources, with both positive and negative aspects. The World Wide Web, consisting of various websites, is essential for our daily lives. These websites can mimic media like TV shows or newspapers, or be interactive specifically for computers. The choice of how to use the internet depends on our individual needs.

Internet Security and Privacy

Cybersecurity involves protecting systems from online threats, such as phishing, social engineering, ransomware, and malware. Phishing involves sending fake emails to steal private information, while social engineering coerces disclosure. Ransomware, a malicious software, extorts money by preventing access to files or systems until a ransom is paid. Malware, on the other hand, damages or unauthorized access to computers.
Data privacy involves individuals’ control over how and how their personal information is shared with third parties. It has become increasingly important due to the rise in internet usage. Technologies like encryption, two-factor authentication, and access control can help safeguard user privacy and enhance data security.

E-Commerce

E-commerce platforms are software that facilitate online purchasing and selling, allowing buyers and sellers to browse products, add items to their cart, and checkout. They fall into three categories: SaaS (software as a service), PaaS (platform as a service), and On-premises (locally hosted by the retailer). Popular platforms include Shopify, BigCommerce, Wix, Big Cartel, Squarespace, Magento, WooCommerce, and Salesforce Commerce Cloud.

Emerging Technologies

Artificial Intelligence (AI) is the ability of a built machine to mimic human cognitive tasks, including computation, data analysis, and human-machine conversation. AI technology includes wearable fitness trackers, chatbots, and navigation apps, such as ChatGPT, Google Maps, Smart Assistants, and self-driving cars.
Blockchain technology, a distributed ledger or database, is crucial in cryptocurrency systems for preserving a safe and decentralized record of transactions. It is used by financial services to speed up closure times and transactions. Also used by some institutions for traceability and contract management.
The Internet of Things (IoT) encompasses a wide range of non-computer Internet-connected devices, including smart watches, fitness trackers, refrigerators, headphones, cameras, automobiles, traffic lights, aviation engines, and home security systems.

Future Trends

5G technology is the fifth generation of mobile networks, designed to connect various devices, machines, and objects. It is used for IoT, mission-critical communications, and improved mobile broadband. Forward compatibility allows it to handle unknown services. 5G offers immersive experiences like VR and AR with faster data rates, lower latency, and lower cost-per-bit.
Virtual reality and Augmented reality are promising technologies for gaming, marketing, e-commerce, and education. Virtual reality is a computer-generated environment that immerses users in their surroundings with realistic objects and visuals, while augmented reality enhances realism through computer-generated perceptual information. These technologies offer better experiences in gaming, marketing, e-commerce, and education, blending the virtual and physical worlds with better, three-dimensional pictures.
