Smartphones v. Computers Essay Example | Topics and Well Written Essays - 1000 words

Smartphones v. Computers - Essay Example Since the start of time, the human race has been trying to find ways to store and move with information without major challenges. Advanced smartphones have been equipped with large storage, which is also supplemented by the external storage disk. Smartphone users have the habit of downloading or transferring significant content. It makes it easy to access information without connectivity. Most people use large storage in smartphones for pictures, music, video, and messages. The convenience that comes with large storage in smartphones explains the high clamor for smartphones in the society. The built-in storage in most smartphones falls within the range of 8GB to 64GB. The large storage has made it easy to access, transfer, and share all types of data. It should be noted that the storage range provided is enough for most people. The relatively high portability that comes with smartphones makes it easy and convenient to carry it everywhere. They are designed and manufactured for easier handling and carrying. They are a bit bigger than standard mobile phones. Portability makes it easy to move with smartphones, which serve as personal data assistants, video and music player, and a connectivity tool. Smartphone manufacturers use ergonomics helps in designing smartphones that are easy to hold and use. Most of the phones have designed to be slim and light to fit into the pocket easily. The essence is to make it very easy to move around with the phone with minimal discomfort. Laptops (Computer)

Measurement and instruments - Lab Report Example on-chip Hall voltage generator for magnetic sensing, a Schmitt activate to offer switching hysteresis for noise denial, a comparator that amplifies the Hall voltage, and output open collector. An internal regulator is used to offer temperature remunerated supply of voltage for internal circuits and enables a large operating supply choice, When current flows through a piece of metal, the voltage can be measured perpendicular to the flow of current and the voltage should equal zero under no influence of a magnetic field (PopovicÃŒ , 74). When a magnet field is introduced perpendicular to the flow of current a voltage is induced. If you reverse the polarity of the magnet the polarity of the induced voltage will reverse. The operation is ignited when the device is placed in a magnetic field. When the material is placed in a magnetic field, the flux lines of the magnet and exerts a force on the material which is a semiconductor. This leads to deflection of electrons and charges. Movement of charge carries is due to magnetic force that they experience (PopovicÃŒ , 204). When current flows through a piece of metal, the voltage can be measured perpendicular to the flow of current and the voltage should equal zero under no influence of a magnetic field. When a magnet field is introduced perpendicular to the flow of current a voltage is induced. If you reverse the polarity of the magnet the polarity of the induced voltage will reverse. There are distinctive features that the instrument has. The features include low current consumption, 3.5V to 24V DC operation voltage, open-Collector pre-driver, wide operating voltage range, temperature compensation, 50mA maximum sinking output current and reverse polarity protection. This is the Hall Effect named after Edwin Hall who discovered this in 1879. The principle which was used was the basic physical principle underlying the Hall Effect being Lorentz force. To generate a potential difference across the device the magnetic flux
