Since then this capability has now become a standard among both. Even though they don't maintain some of the functionality and computing power as their desktop and laptop counterparts, they are still capable of word processing, mathematical computation, and other productivity programs that businessmen and students use. On top of that, they are also extremely durable and affordable which make them perfect for educational tools. Students will find them easy to manage, organize, and carry around as well as a "distraction free" resource because of their minimalistic capabilities.
Couple these advantages with internet access to mobile hotspots such as school libraries and it can be easily seen why this device had dominated the market for so long. It has only been a recent trend for individuals to pick up the tablet despite it's rudimentary processing power and it has been speculated that this is due to the tablet's sleek design and effective marketing strategy toward the younger generation.
Smartphones are mobile personal computers that use advanced mobile operating systems that allow mobile, handheld usage. A smartphone is much smaller than a tablet making it easy to fit one in a pocket. Not only can a smartphone make voice calls it can also send and receive text messages. Smartphones have digital personal assistants, event calendars, media players, video games, GPS navigation, and the ability to take digital photos and videos. A smartphone can also access the internet by either connecting to Wi-Fi or using cellular data.
The user may also download many helpful apps to a smartphone. Data is calculated and processed on a daily basis through computers in business, at home, and in education. Data is essentially the raw facts that are usually typed into a computer. We call these "raw" facts due to them being unorganized. They can come in any form from audio and visual, to text and numerical.

When the data is entered into the computer, it is considered input. The computer calculates the data and spits out the information. Since this information is the output, it becomes the organized version of what used to be raw facts. This system is considered information processing.
Data can also come in other forms including figures, experiments, and surveys. Most everything that is entered into a computer becomes data, which is why this term is so vital to understanding computers and how they operate. When most people think of information, the first source that comes to mind is Google. Google allows you to access a lot of information in a short amount of time. What most do not know is that is exactly what a computer does behind the scenes every time you are entering data into a computer, most of the time without even considering it to be "data.

Many online sources provide endless amounts of information. Without information, people will not have reliable sources for school and their career. Work can be made much easier with information, including jobs which need to calculate employee's total hours worked, or any "total data" that needs to be found or calculated. Data and information are very valuable, and is most certainly the backbone of a computer.
These two components may help your computer to be user-friendly by working behind what you are typing to make data useful and organized. The Industrial Age: First general mechanical computer was proposed and partially built by the English inventor Charles Babbage in It was programmed using punch cards, and also featured integrated memory. Historians consider it to be the first design concept of a general-purpose computer. Unfortunately, because of funding issues the Analytical Engine was never built while Babbage was alive.
It wasn't until that Henry Babbage, Charles Babbage's youngest son, was able to complete a portion of this machine which was able to perform basic calculations. The Analytical Engine was to be a general-purpose, fully program-controlled, automatic mechanical digital computer. It was designed to consist of four components: the mill, the store, the reader, and the printer- which are all essential components of every computer today.
Digital computing was invented by Claude Shannon in late 's. What he envisioned was a computer built from electrical circuits instead of motors. Today, it is difficult for any student to imagine life without a computer. However, computers have only been around since the mid 's. The computer industry went from making computers that took up an entire classroom to currently being able to fit into a student's backpack.
Also, computers used to be much more expensive and required a greater amount of energy than today's computers.

Finally, in the s, people began placing these foreign objects into their home. During this time, people had to really study and be patient with this handy device. Computers today are much smaller, lighter, require less energy, and cheaper. However, in today's generation, computers are second nature to most people, and one could not imagine life without them.
Computers in our generation seem to be integrated in our every day life to assist in multiple tasks related to our many needs. So much so, it is difficult to picture our world without them. However, with great success comes great patience.
In the first computer model for example, the machine required certain inputs, referred to as punch cards, and physical work to reprogram the computer. The computer itself was nowhere near as helpful, simple, nor convenient as it is today. The first generation computers were built with thousands of vacuum tubes, required physical effort to re-wire the computer, and could only solve one problem at a time. The second generation of computers introduced transistors, which replaced the vacuum tubes. Transistors simply acted as a light switch, allowing the electronic circuits to either open or close.
Both first generation computers, and second generation computers continued to use punch cards for their input. Soon after, , the third generation used a system of integrated circuits, which incorporated many transistors and electronic circuits on a single silicon chip.

The third generation of computers started the innovative trend of smaller and more reliable computers. Finally, the development of our current computers, used by practically everyone in society, began. The fourth generation of computers began in , when it was possible to place far more transistors onto a single chip- the microprocessor. This discovery led within the decade to the creation of IBM's personal computers, as well as the popular Apple Macintosh.
Consumers currently use inputs, outputs, and storage that consist of: keyboards, mice, monitors, printers, speakers, hard drives, flash memory media, and optical disks. Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come.
The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization. Although the movement from vacuum tubes to microprocessors seemed to take a while, compared to the beginning of civilization thousands of years ago, this advancement happened very quickly.

However, it also opens the human mind to realize that innovation takes trial, error, and patience. The term hardware refers to the components used to build a computer. Breaking down the components into categories, you will find four main groups:. Although these are the four main categories, there are three more components to consider that do not fit into those main four:. A computer case is used to put the essential components of a computer in. This provides an enclosed space and easier organization for the components to go.
A power supply unit PSU is used to power all components inside the case.

What this means is that each component needs a certain amount of volts to work and the power supply will regulate the volts accordingly. An expansion card is used to enhance certain attributes of the system. For example, a sound card can enhance sound by giving you surround sound capability. Another example is a video card, this will enhance the graphics of your system. This category refers to the components a computer uses that receive data and send information. Input devices do the receiving and the output devices do the sending.
Some examples of input devices are a keyboard, mouse, and a gaming controller.
