Comparison of some common motherboard form factors (pen for scale) A PC motherboard is the main circuit board within a typical desktop computer, laptop or server. Its main functions are as follows: To serve as a central backbone to which all other modular parts such as CPU, RAM, and hard drives can be attached as required to create a computer
The article "Usage share of operating systems" provides a broader, and more general, comparison of operating systems that includes servers, mainframes and supercomputers. Because of the large number and variety of available Linux distributions, they are all grouped under a single entry; see comparison of Linux distributions for a detailed ...
A mid-tower computer case from c. 2011. In personal computing, a tower unit, or simply a tower, is a form factor of desktop computer case whose height is much greater than its width, thus having the appearance of an upstanding tower block, as opposed to a traditional "pizza box" computer case whose width is greater than its height and appears lying flat.

Post Coffee Lake, increased core counts meant hyper-threading is not needed for Core i3, as it then replaced the i5 with four physical cores on the desktop platform. Core i7, on the ...
A computer has a certain resistance to air flowing through the chassis and components. This is the sum of all the smaller impediments to air flow, such as the inlet and outlet openings, air filters, internal chassis, and electronic components. Fans are simple air pumps that provide pressure to the air of the inlet side relative to the output side.
