They are called simple machines.
A machine with few or no moving parts is called a stationary or static machine. These machines typically rely on simple mechanisms like levers or hydraulics to perform their functions without the need for complex moving components. Examples include a simple lever or a hydraulic press.
A hammer is a tool with few or no moving parts. It consists of a handle and a head, with no internal mechanisms that require movement to function.
Machines of all kinds including computers breakdown without occasional maintenance. But as computers have few moving pieces that wear out due to friction they usually can run much longer than machines like cars with many such parts between maintenance actions.

There are quite a few machines that start with the letter B. A few of the machines are baling presses, boiler, and a beveling machine.
This question is based around the untrue premise that only professionals can properly service a computer. In truth, computers are relatively simple machines- they have very few discrete parts, even fewer moving parts, and all components are standardized. The prevalence of so-called "professionals" is mainly due to large companies taking advantage of people's ignorance. Likewise, often the fees charged are exorbitant to the point of being absurd and one will even see charges for extra parts or replacement parts when the originals are not, in fact, bad.

Olligopoly's word parts mean, few many. That means that the industry is controlled by only a few people.
About 90 U.S. companies produced automatic vending machines or parts for them in the 1990s. Although a vast majority of vending machines were manufactured by large companies, the industry did sustain quite a few smaller firms.
yes. You usually need a few minutes to let the oil circulate in the engine. If you dont , the first few minutes of driving might wear the moving parts that the oil is meant to protect.
Non moving parts of an engine, to name a few are engine block oil pan oil plug spark plug rocker cover intake/exhaust manifold core plug ignition coil oil filter cylinder head Hope that helps some, ~Ashley
A mass of rock moving through space is called an asteroid. These rocky objects can range in size from a few meters to several kilometers across and orbit the Sun.
