School curriculums nowadays would all have computer education as a major part. At an early age, students are taught to be proficient and well-versed in computers since it plays a major role in almost all fields today. Business transactions can all be made online which make proficiency in the internet a big part if you want to make it big in the industry. The field of medicine have reached and surpassed milestones and breakthrough through these machines that enable them to come up with materials and even go as far as entering the human body. And of course, communication is at its peak as more and more features are installed in these portable devices that go beyond calls nowadays. Some would even say that calculators are a thing of the past. Well, the people who say that have not been fortunate enough to try the TI 84 Calculator.

The TI 84 Calculator is another quality product of the Texas Instruments Company Like many of their other products, the TI 84 Calculator is packed with features that many would assume that it is a computer already. The TI 84 Calculator comes in two models: the TI 84 Plus and the TI 84 Plus Silver Edition. There is no plain TI 84 model since only the two were released in 2004. It is considered an upgrade of the TI 83 Plus. However, compared to its predecessor, it has more than 80 additional features that make it one of the most advanced models of its time. The memory of the TI 84 Calculator is about 3 times as large, and processor is about 2.5 times as fast. A USB port, which is USB On-The-Go compliant and clock functions were added to the new model. It is also similar to the TI-Nspire calculator that allows connecting to USB based data collection device. Also, it supports device to device transfers over USB rather than over the Link port.

The TI-84 Plus Silver Edition was also released in 200. Its predecessor is the TI-83 Plus Silver Edition. Similarly, it features a 15 MHz Zilog Z80 processor, 24 kB user available RAM. There is 1.5 MB of Flash ROM. Like the TI 84 Calculator that was first released, the Silver Edition includes a built-in USB port, a built-in clock, and assembly support. It uses 4 AAA batteries and a button cell battery for back-up.

There are four different types of programs which can be programmed into the TI 84 Calculator. First is the TI-BASIC, followed by the Z80 assembly language, Axe Parser compiled programs, and Flash applications. Many applications may be installed through these programs that extend the many functions of the TI 84 Calculator. These include games and even note-taking applications. The calculator transforms from just a machine for computing to an all-in-one device fit for work and school.

The TI 84 Calculatorcan also be used on the SAT and ACT examinations as well as International Baccalaureate examinations like its predecessors.
