Bluetooth - An Overview

Bluetooth is a wireless technology standard for exchange and transfer of data over short distances from fixed and mobile devices.

 It is a low power wireless connectivity technology used for building personal area networks and is at the forefront of wireless connections that takes place between different technological devices.  

It's similar to Wi-Fi in that it operates over radio waves but Bluetooth can work between any two enabled devices and does not require additional network equipment such as routers or modems, making it easy to use for sending data between mobile electronics over close ranges.

The technology is compatible with devices including: phones, headsets, and even medical equipment. and you can make calls, listen to music, and send all kinds of information wirelessly without the need for wired connections.

 Its main aim is to eliminate the need to, connect, plug in, install, enable or configure anything to anything else. It can also be used to connect to the local area networks.  

It works over a certain distance  between devices, but that range is more than enough for many home, car, health and consumer electronics applications

 Bluetooth is one of the most convenient developments in wireless technology and its usage has increased over the years from electronic devices including mobile phones, headsets, laptops, printers and music players to HD televisions.

Unlike a wireless network, Bluetooth does not need any configuration to start a connection and perform file transfers and works well for business environments in which wireless file transfers are utilized including laptops, where establishing a wireless connection is as easy as pressing the Bluetooth shortcut or hot key.

The Bluetooth connection can be securely established without interference from unrecognized devices by entering an identification number for the connection. 

The user of the master device–the one which starts the connection–can opt to enter a PIN which creates the secure usage loop.

Unless a device is already paired to your device, you have the option to accept or reject the connection and file transfer.

It is also seeing the developments where the drivers will monitor the important information like the vehicle diagnostics , the traffic , and even the driver health — all in the real time .

This prevents the spread of unnecessary or infected files from unknown users from transferring to your device.

Accessing a Bluetooth device doesn't cost money; all you need is the Bluetooth capability.

It also has the use of the software that allows the  hackers to send and receive audio to and from a Bluetooth enabled car stereo system so Bluetooth enabled devices are upgrading the security to ensure that these Bluetooth security lapses do not arise with their products to protect against these and other forms of vulnerability .

Bluetooth has a downside when it comes to file sharing speed. Compared to the up to 4.0MBps rate transfer of infrared, Bluetooth can only reach up to 1.0MBps, meaning that it transfers files slowly. 

In transferring or sharing larger files at a closer distance, other wireless technology–like infrared–is better.Bluetooth is not recommended for establishing Internet connections because of its limited transfer rate. A LAN connection is more efficient.

Culture conflict in globalization

Globalization is a phenomenon that has made its presence felt in our daily lives and has changed the way we live and has led to the interaction between diverse cultures through convergence of world views, products and ideas, whereby cultural conflict can make or break a business that is trying to establish itself in a foreign country. One of the strategies that make a difference when it comes to establishing a successful presence in a foreign land is effective communication. This includes not just language and does not include only English as although English is the global language of doing business, many countries prefer to function in their local language which can be a cause for concern but this problem is minimized as most countries have a sizeable population who are bilingual and are comfortable with using English despite the fact that it is not their mother tongue. Non-verbal communication also plays an important role and one needs to be aware of the cultural nuances and cu...

Touch Screen Technology Explained

A  touch screen  is a display screen that is found on computers, laptops, smartphones and tablets that works as a visual input device with screens that are sensitive to pressure. The user interacts with the computer screen without the appearance of physical keyboard just by clicking the pictures or words that appear on the screen. Touch screen that are found in devices like smartphones and tablets are designed to keep the fingerprints from being visible. It is a bigger screen that fits in well with the multi media functions are the ones that are found on the latest mobiles.  One can watch videos, movies or TV shows that makes it easier to view on a larger surface area that covers the the complete screen of the mobile. It does away with the keypad and for  music, photographs and videos, you hardly need buttons and you only need camera buttons when you take a picture.  It makes sense for these to be designed to appear on the screen, rather than to stick...

Software Testing - An Overview

Software testing is a process that is implemented to check the quality and result of the software or application being developed.  It is done to allow the companies to understand and appreciate the risks that are involved during software implementation.  It helps to point out the defects and errors that were made during the development phases and is used to makes sure of the customer reliability and satisfaction in the application. Testing allows developers to deliver software that meets expectations, prevents unexpected results, and improves the long term use of the application. It also depends the purpose of testing and the software requirements, the appropriate methodologies are applied.     Test techniques include the process of executing a program or application with the intent of finding bugs,errors or other defects, and verifying that the software is fit for use. You need to verify that the completed software package functions according ...
