Battery is an electrochemical energy storage system packaged as a physical component. Strictly speaking the term means an array of multiple interconnected cells by analog to a gun battery, but nowadays it is often used to designate a single cell. Batteries contain harmful substances, such as acids and heavy metals. If batteries are not correctly used, stored and discarded, these harmful substances may leak, or the batteries may overheat or burst. An advantage of a battery pack is the ease with which it can be swapped into or out of a device.

This allows multiple packs to deliver extended runtimes, freeing up the device for continued use while charging the removed pack separately. It is the flexibility of their design and implementation, allowing the use of cheaper high-production cells or batteries to be combined into a pack for nearly any application. It is important to take safety precautions when servicing a battery pack as they pose a danger as potential chemical, electrical, and fire risks. We should not use different types of batteries together; we do not mix old batteries with new ones. We need to Store batteries in the original packaging in a cool, dark place. Keep them away from household chemicals and food.

A scientific calculator is a type of electronic calculator. But usually it is not always handheld; it designed to calculate problems in science (especially physics), engineering, and mathematics. Scientific calculator has almost completely replaced slide rules in almost all traditional applications, and it is widely used in both education and professional settings. The feature set differs between manufacturers and models; however, the defining features of a scientific calculator like Scientific notation for calculating large numbers, floating point arithmetic ,logarithmic functions, using both base 10 and base e ,trigonometry functions, exponents and roots beyond the square root, etc…

Scientific calculators are used widely in any situation where quick access to certain mathematical functions is needed, especially those such as trigonometric functions that were once traditionally looked up in tables. The benefit of a scientific calculator is to Save time and reduce errors with the unparalleled computing power. It have a clean interface that’s easy to read and easy to use. A scientific calculator is used routinely by scientists and engineers. A good scientific calculator must be very precise and it must handle the huge dynamic range of numbers that are encountered in our understanding of science. Scientific calculators must provide functions that help us analyze data as well as functions that simply calculate numbers.

UPS is known as an uninterrupted power supply. It is also known as a battery back-up, provides emergency power and, depending on the topology, line regulation as well to connected equipment by supplying power from a separate source when utility power is not available. The primary advantage to a UPS is that in cases of sudden power loss, such as during a storm, the UPS will continue to power the computer system long enough for us to save our work. A UPS, however, can be used to provide uninterrupted power to equipment, typically for 5–15 minutes until an auxiliary power supply can be turned on or utility power is restored.

A UPS is typically used to protect computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. There are various common power problems that UPS units are used to correct. Voltage sag will be Transient under-voltage and its Causes flickering of lights. UPS systems can be designed to be placed inside a computer chassis. There are two types of Internal UPS. The first type is a miniaturized regular UPS that is made small enough to fit into a 5.25? CD-ROM slot bay of a regular computer chassis. The other type are re-engineered switching power supplies that utilize dual power sources of AC and/or DC as power inputs and have an AC/DC built-in switching management control units. The only disadvantage is that batteries have a certain lifetime (3-5 years) and therefore there is an expense involved for it.

Fax machine is a telecommunications technology used to transfer copies of documents, especially using affordable devices operating over the telephone network. Short for facsimile machine, a device that can send or receive pictures and text over a telephone line.The device is also known as a telecopier in certain industries. A “fax machine” usually consists of an image scanner, a modem, and a printer. As a security precaution, thermal fax paper is typically not admissible as evidence in a court of law unless photocopied.

This is because the ink used on fax papers is delible, brittle and tends to come off over long periods of storage. Fax machines work by digitizing an image dividing it into a grid of dots. Each dot is either on or off, depending on whether it is black or white. Electronically, each dot is represented by a bit that has a value of either 0 (off) or 1 (on). On the receiving side, a fax machine reads the incoming data, translates the zeros and ones back into dots, and reprints the picture. The speed of fax machines transmits data at different rates from 4,800 bps to 28,800 bps. Most fax machines use a thermal printer that requires special paper that tends to turn yellow or brown after a period.

Bluetooth is a short-range radio hookup that resides on a microchip. It was initially developed by Swedish mobile phone maker Ericsson in 1994 as a way to let laptop computers make calls over a mobile phone. Bluetooth is a wireless protocol for exchanging data over short distances from fixed and mobile devices, creating personal area networks. It can connect several devices, overcoming problems of synchronization. Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, digital cameras, and video game consoles through a secure, globally unlicensed Industrial, Scientific, and Medical 2.4 GHz short-range radio frequency bandwidth. It is a Wireless control of a communication between a mobile phone and a hands-free headset. This was one of the earliest applications to become popular.
It eliminate cables linking computers to printers, keyboards, and the mouse. The most advantage of blue tooth is an economic wireless solution (both data & voice) used for short distance. Companies are taking the benefit by using this in their new and future products to make life much easier for everyone. There are also some disadvantages available in Bluetooth some of them are like when we are using up more battery power when we leave our Bluetooth enabled on our phone all day. When using Bluetooth internet, the connection can sometimes run very slow so Bluetooth internet is not highly suggested for all cases.
