Digital computers, well, your using one to ask your question!
Digital computers, most people just call them Computers, or PC's, are used for a variety of things.
For one, the internet, which you are using right now on a Digital computer. All computers are digital.
Perhaps you should research PC's

Other uses:
Games
Writting documents
Reading information
Information databases
Website hosting (servers)
Research
Data collection
And so much more!
A digital calculator which was the basis for modern computers.
That is it. All known computers can be put in one of those categories. Some may argue that a neural net computer (like the human brain) defines a fourth type of computer, but even that really is a hybrid.
Digital computers calculate by manipulating encoded symbols using logic circuits.Analog computers calculate in a wide variety of ways with continuous analogous representation of data.
The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
An analog computer is any computer that represents its data in the form of continuously variable signals instead of the discontinuous encoded symbols used by digital computers.
digital computers were first used in 1942 analog computers were first used in about 100BC
a. computers are used in all digital technologies.
At this time, no, most computers are digital. However from the 1930s through the 1960s analog computers probably did outnumber digital computers as they were generally smaller and less expensive than digital computers.
Digital computers work with exact discretely coded representations of numbers.Analog computers work with approximate continuous representations of numbers.Hybrid computers are computers that are part digital part analog.I have used all three types, each has advantages.
For example digital computers to edit images, (digital) cameras to obtain images or computers to render them.
Digital computers are purely digital, i.e. they use digital(electronic) means to process data. Hybrid computers conversely use both digital and analog technologies.
Because - computers can only process digital information. Therefore all analogue input must be converted to digital before processing.
Because the first, second, and third generation computers were also digital computers.
Several early digital computers were made of electromechanical devices similar to those used to build automatic dial telephone exchanges used at the time. First generation digital computers were made of vacuum tubes. Second generation digital computers were made of discrete transistors (most used germanium transistors but later some silicon transistors). Third generation digital computers were made of (hybrid, SSI, MSI, LSI) silicon integrated circuits. Fourth generation digital computers are made of microprocessors and other (VLSI, ULSI, etc.) silicon integrated circuits.
Included in this industry are digital computers, analog computers, and hybrid digital/analog computers.
