How is data represented in a digital computer?

Data is represented in a computer by means of simple on/off switches, and digitally these become 1 and 0. Millions of switches in combination create all the data in a computer system. Computer data handing is an electrical system; therefore the on/off switches become electrical switches. The current is either turned on or off and the various ...

What is digital data?

Digital data is information stored on a computer system as a series of 0's and 1's in a binary language. Information is stored on computer disks and drives as a magnetically charged switch which is in either a 0 or 1 state. A single 0 or 1 is also called a bit.

How many bits are in a kilobyte?

Computer disks and drives hold many switches to store this information as lines of 0's and 1's. A byte is composed of eight bits, and a kilobyte is 1,000 bytes; 1,000 kilobytes equals one megabyte. When information is put into a digital form, it is converted into sequences of 0's and 1's that can be interpreted by other computer systems. Digitizing information is the process of converting information into digital form and is necessary for a computer to be able to process and store information.

What is a sequence of bits?

A sequence of bits can represent anything from a single letter all the way up to the exact time a certain pixel will display on a certain part of the screen as part of a movie. Digital data can also be used to store music or gaming data.

If you take a picture with the camera on a smartphone, the image is recorded as a map of many pixels. Each pixel is a very small square with a certain color. The placement of each pixel and its color is an individual line of binary code. What looks to the human eye like a photograph is really the expression of an underlying digital code. Digital data can be used to store very complex information. Music, movies, and games can also be stored as what are ultimately sequences of 0's and 1's being interpreted by a computer.

Where does the word "digital" come from?

The word digital comes from the same source as the words digit and digitus (the Latin word for finger ), as fingers are often used for counting. Mathematician George Stibitz of Bell Telephone Laboratories used the word digital in reference to the fast electric pulses emitted by a device designed to aim and fire anti-aircraft guns in 1942. The term is most commonly used in computing and electronics, especially where real-world information is converted to binary numeric form as in digital audio and digital photography .

Proactive decision making. Relevance is the currency of the digital age. This requires making decisions, based on intelligence, that deliver content and experiences that are personalized and relevant to the customer. Remembering customer preferences is a basic example of this capability, but it also extends to personalizing and optimizing the next step in the customer’s journey. Data providers such as ClickFox, for example, blend data from multiple channels into one view of what customers are doing and what happens as a result. In the back office, analytics and intelligence provide near-real-time insights into customer needs and behaviors that then determine the types of messages and offers to deliver to the customer.
