As technology has improved over the past few decades, cell phones have only gotten better and better.Though most people do not stop to consider the idea, it is still an amazing feat even today that what was once only an idea presented in movies and novels, has now become our number one modern-day communication device. Many people have even disconnected their landline telephones and replaced them with cell phones. With the ability to make phone calls, send and receive text messages and pictures, and even access the Internet, cell phones Read More

A piezoelectric display is a display – such as on a mobile display – that can harden protectively when the device is turned off and soften into a touchscreen that, when pressed, can be depressed. In other words, it is a display that can change shape or texture based on whether it is on or off. While it has only been researched in previous years, it is suggested that this technology will make it to the forefront of mobile devices in the next year as well as future years. How Read More

A multivibrator is an electronic circuit that rapidly switches because of positive feedback between multiple states. The switch’s output is harmonic. Three types of multivibrator circuits are used in industry today: astable, monostable, and bistaple. Types of Multivibrators The three multivibrator types are: Astable Multivibrator – The circuit is not considered stable in either of the two possible states. It continually switches from one of the potential states to the other, but does not require a clock pulse or other input in order to operate. Monostable – One of the Read More

An automated dialer is a piece of software which is designed to dial the telephone automatically. Automated dialers store names and telephone numbers and enable to you easily contact people without remembering phone numbers. Most automated dialers will retrieve contact information from other databases, such as your Microsoft Outlook Contacts list. Some automated dialers will also dial a telephone number at regular intervals until a person answers the phone. When the person answers the telephone, the automated dialer will sound an alarm to let you know that the called party Read More

What was once only a dream has now become a reality as space travel is a regular activity in our society. With thousands of satellites in orbit, the Hubble Space Telescope that can see other galaxies, regular shuttle launches, and prototypes for vehicles that can fly in and out of the atmosphere, it makes sense that we have a permanent space station in orbit. To fully understand the concept of a space station, however, it is important that people learn how a space station works. In this article, we will Read More

Cell phone radiation refers to the electromagnetic waves that cell phones produce and the user’s body, particularly the head, absorbs. Cell phone companies, research agencies, and other groups have known about cell phone radiation for some time. However, they have not yet found any conclusive evidence to show whether cell phone radiation does, in fact, cause harm to the human body. While conclusive evidence has not been found, there does seem to be some correlation between cell phone use and brain tumors, some forms of cancer, and blood flow problems. Read More

The constructor handles the task of converting basic types to class types very well. But you cannot use constructors for converting class types to basic data types. Instead, you can define an overloaded casting operator that can be used to convert a class data type into a basic data type. The general form of an overloaded casting operator function is shown below. This function is also known as a conversion function. Syntax: .cf { font-family: Lucida Console; font-size: 9pt; color: black; background: white; } .cl { margin: 0px; } .cb1 Read More

SDR SDRAM is Single Data Rate SDRAM. SDR SDRAM is the original SDRAM standard, which has since been replaced by DDR SDRAM. DDR SDRAM doubles the bandwidth of SDR DRAM by transferring data twice per cycle on both edges of the clock signal, implementing burst mode data transfer. Standard SDR SDRAM DIMMs SDR SDRAM is normally packaged in DIMM modules. SDRAM DIMM modules are sold according to clock speed (MHz), bus speed (megatransfers per second), and transfer rate (megabytes per second. DIMM Module Chip Type Clock Speed Bus Speed Transfer Read More

Remote Access and VPN Server Security Issues Remote Access Servers (RAS) provides access to the network for remote users. The different types of remote access connections are Dial-in remote access, VPN remote access, and Wireless remote access. Dial-in remote access uses modems, servers running the Routing and Remote Access (RRAS) service, and the Point-to-Point (PPP) protocol to enable remote users to access the network. VPN remote access provides secure and advanced connections through a non-secure network. VPN access uses encryption to create the VPN tunnel between the remote access client Read More
