I'll outline the skills that are essential and necessary to become a White Hat Hacker in this article. If you can master all of these skills, you will certainly become a successful white hat hacker. So, without further ado, let's get down to business. 1. Knowledge of computer networking One of the most important skills for becoming an ethical hacker is networking. The PC network is simply the connectivity of several devices, most commonly referred to as Hosts, that are linked via various methods to send/receive data or media. Computer Network Tutorials can help you learn how to organize your PC. 2. Computer Skills PC talents are the knowledge and skills required to use computers and related technology. Information preparation, document management, and introductions are frequently included in basic PC abilities. Overseeing data sets, scripting, and conducting computations in accounting pages are all examples of advanced PC skills. A master of PC frameworks is required of a...
Battery is one of the most important parts of a mobile phone or a tablet as this is what keeps the device mobile. Mobile phones and tablets these days come with different types of batteries and it is their quality that decides how much energy they can store and hence how long the device can be operated with a single charge.
There are also limitations on size and weight as a big battery would make the device heavy and bulky, which is not a comfortable option. So, Basically battery designers work on three parameters such as chemical composition, size, and weight.
In terms of chemical composition, there are only two types of batteries used in modern cell phones Lithium Polymer and Lithium Ion.
Lithium Polymer (Li-Poly) Batteries
Li-Poly is the latest and most advanced technology for cell phone batteries. This makes the batteries ultra-lightweight, they do not suffer from memory effect and will deliver up to 40 per cent more battery capacity. “Memory effect” happens when rechargeable batteries are not fully discharged between charge cycles.
Lithium Ion (Li-Ion) Batteries
Lithium-ion batteries were first commercialized in 1991, and widely applied to markets for mobile devices and electric vehicles. The only real drawback of Lithium Ion batteries is that they have higher energy density compared to Li-Polymer.
Both Li-ion and Li Polymer batteries have the same chemical composition but the difference lies in their tendency to overheat.
Way to Boost Life of Batteries Used in Smartphones
However, with standard lithium batteries requiring charging times of at least an hour to fully charge, even with quick charging technology, and considered to have reached their limit for capacity expansion, there have been numerous attempts to explore use of new innovative materials.
Recently, a team of researchers at the Samsung Advanced Institute of Technology (SAIT) developed a “graphene“; a unique battery material that enables a 45% increase in capacity, and five times faster charging speeds than standard lithium-ion batteries.
In theory, a battery based on the “graphene” material requires only 12 minutes to fully charge. Additionally, the battery can maintain a highly stable 60 degree Celsius temperature, with stable battery temperatures particularly key for electric vehicles. Among the materials looked at, ‘graphene’ has widely become the primary source of interest as the representative next generation material.
