Bluetooth technology

Introduction

Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks. In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 meters. Devices connected in a Bluetooth network communicate with each other using ultra-high frequency (UHF) radio waves. These are electromagnetic waves with frequencies around 2.4 gigahertz (2.4 billion waves per second).

Bluetooth technology operates on radio frequencies in the 2.4 GHz range. The two Bluetooth standards currently in use today about: Bluetooth Classic, which supports two distance data rate, Basic Rate (BR) and Enhanced Data Rate (EDR). 

The name dates back more than a millennia to King Harald “Bluetooth” Grossmont who was well known for two things: Uniting Denmark and Norway in 1958.

• Bluetooth technology allow devices to communicate with each other without cables or wires.
• Bluetooth relies on short-range radio frequency, and any device that incorporates the technology can communicate as long as it is within the required.
• Jaap Heartens has been active in the area of wireless communications for more than 25 years. 
• In 1994, he laid the foundations for the system that was later known as the Bluetooth Wireless Technology, enabling connections between a seemingly endless array of devices.

 Internet of things

Introduction

The Internet of Things (IOT) describes the network of physical objects—“things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet.

IOT enables these smart devices to communicate with each other and with other internet-enabled devices, like smartphones and gateways, creating a vast network of interconnected devices that can exchange data and perform a variety of tasks autonomously. This can include everything from monitoring environmental conditions in farms, to managing traffic patterns with smart cars and other smart automotive devices, to controlling machines and processes in factories, to tracking inventory and shipments in warehouses. 

 The collective network of connected devices and the technology that facilitates communication between devices and the cloud, as well as between the devices themselves. 

IoT networks can be categorized into four main types: LAN/PAN, LPWAN, and Mesh protocols. The classification is based on factors like network coverage and available bandwidth. 

• The internet of things is a technology that allows us to add a device to an insert object (for example: vehicles, plant electronic systems, roofs, lighting, etc.) 
• In conclusion, IoT offers significant advantages like increased efficiency and data-driven decision-making.  
• The term 'Internet of Things' was coined in 1999 by the computer scientist Kevin Ashton. 

Network Safety Tips

 Introduction 

Network security is the protection of the underlying networking infrastructure from unauthorized access, misuse, or theft. It involves creating a secure infrastructure for devices, applications, users, and applications to work in a secure manner.

Network Security is vital in protecting client data and information, keeping shared data secure and ensuring reliable access and network performance as well as protection from cyber threats.

1.     Don’t share your personal information

2.     Don’t download from unknown sources

3.     Don’t open suspicious attachments

4.     Don’t use public Wi-Fi 

5.     Don’t become a victim to phishing, smiting and hacking

 

Using strong passwords is especially important when you're spending money online. Good passwords should: never be shared or written down somewhere - don't tell helpline staff your password. the longer the password, the harder it is to crack - so aim for a password with a minimum of eight characters.

We all have a basic human need to feel safe: to be free from threats, to have trust and support, to be able to relax. Security – the sense of being safe physically, emotionally, and environmentally – impacts wellbeing in many ways, including physical health, emotional wellbeing, and how we manage stress.

• Teaching them about online security protects personal information, prevents cyberbullying, and promotes responsible digital citizenship. 
• Learning Organization.
• Commitment and Engagement.
• Playing Games.
