In a four loop DC generator how are the loop ends connected to commutator segments?

The Asker of this question either knows the answer already and wants to test fellow engineers to describe the system in plain words, or this is another student's homework or exam question!
The method used to fit all the wires neatly into the cramped amount of space available is a clever combination of interweaved horizontal and vertical loops, sometimes known as "knowing how to do knitting with very thick copper wires"!
This kind of question really needs a diagram to illustrate the answer but such diagrams are either the copyrights of various authors of books about the theory of operation and the practical design of electrical machines or are manufacturers' patented designs, neither of which can be published here on WikiAnswers.

what is Lap winding and wave winding?
The ends of lap windings are connected to adjacent segments of the machine's commutator, whereas wave windingsare connected between segments that are some distance apart. This results in lap windings having 2p parallel paths, where p represents the number of pole pairs; whereas a wave winding has just two parallel paths.

What is the function of carbon brushes in dc machine?
The carbon (graphite) brushes in a generator are used to connect external circuits in the generator to the rotor through the commutator. But you want to know what that means, right? Darn it, we always see these "trick" questions here. Okay, this is the scoop. The rotor in a generator is (usually) a group of windings. These are coils of wire. But they need to be connected to the "outside" or non-moving parts. Each coil has two ends, and these ends are connected to copper segments (sometimes called "lands") on the commutator. The segments are all in a ring around the end of the rotor, and the brush or brush sets ride on them. The other end of the brush(s) is(are) connected to wires to electrically connect them to appropriate places in the non-moving parts of the generator. The brush is conductive (naturally), and it is soft enough to provide a good "wear point" against the copper segments. The brushes do most of the "wearing away" in this application, and it is a fairly easy and straight forward evolution to replace them. In the motors of power tools, some of the units have a way to access the brush holder without taking the housing apart. Particularly the older ones. Anyway, it is said that a picture is worth a thousand words. Use the link below and take a look at the pictures. It's all there.
What is the difference between a synchronous motor and a generator?
A DC generator is Direct Current most common in industrial environments. Limited to DC equipment such as motors, cranes, certain types of lighting etc. A AC generator is Alternating Current can be used in virtually every environment. These are used for virtually everything from residential dwellings to large steel manufacturing facilities.

What is the difference between a populated segment and an unpopulated segment?
populated segments a network segment that contains ends nodes,such as work stations. unpopulated segments a network segment that does not contain end nodes, such as workstations. Unpopulated segments are also called link segments.
What is the function of brush in a dc generator?
It has two main functions in a generator - firstly, it transfers the electrical energy from the (moving) armature coils to the (stationary) external electrical load circuit. The brushes are made of graphite, with a tiny trace of copper in it, so they're self-lubricating where they ruib on the copper commutator bars (those copper strips on the armature that the coil ends connect to). Secondly, the electricity generated in the rotating armature coils is alternating current, and the brushes, working with the commutator acts like a switch to reverse the connections between the coil ends and the external circuit when the alternating voltage reverses its polarity (+ and -) to give direct current in the external circuit.

Are both ends of the battery or only one end connected to the lighted bulb?
Both ends of the battery are connected, to make a complete circuit.
How do electric generators convert kinetic energy into electrical energy?
They revolve sets of coils of wire across a strong magnetic field, and this induces electrical currents in the coils. NB The current will only flow if thetwo ends of the coils are connected, and this is achieved by whatever circuit is connected to the generator's output.
