What is a motherboard

A printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted.

Describe a motherboard

A motherboard is the main printed circuit board (PCB) in a computer. The motherboard is a computer's central communications backbone connectivity point, through which all components and external peripherals connect. Motherboards can be found in virtually all computers, especially desktop and laptop PCs

Who made motherboard

The first motherboard (then called a planar or a "breadboard") was invented by IBM and sold on its first personal computer (PC)

CPU

What is CPU

A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions

how small is the CPU

Most modern CPUs employ word sizes that are a power of two, for example, 8, 16, 32, or 64 bits.

who made CPU

Italian physicist Federico Faggin invented the first commercial CPU. It was the Intel 4004 released by Intel in 1971. Then the Intel 8008 was introduced in 1972, followed by the 4040, an improved version of the 4004 in 1974

The melting point of them

Modern systems tend to shut down at 100C(212F) or lower if set in the BIOS. This is done to prevent damage to the processor, so I'm not sure it

wires

what are wires 

Wires are pieces of metal that transport electricity. They are usually flexible which makes them easier to use.

250

the longest wire made

It is 39,000 kilometres (24,000 mi) in length and uses Wavelength Division Multiplexing (WDM) technology with Synchronous Digital Hierarchy (SDH) transmission to increase capacity and enhance the quality of the signal, especially over long distances (this cable stretches from North Germany to Australia and Japan).

who made wires

Thomas Edison and the Electrical Power Cable. The invention of the underground power cable was a ground breaking and innovative creation that birthed our every day lives into a new world of light forever. Thomas Edison and his greatest invention.

750

when was it made

When Was Wire Invented? A cylindrical and flexible metal strand, evidence of wire has been found in archaeological sites dating back 5,000 years. Initially, the wire was used in jewelry. Metal strips would be pushed through holes in stone beads so the metal would fold over into a tube shape

1000

the melting point of wires

Generally, it ranges from 1,085°C (1,985°F) to 1,215°C (2,219°F). This wide range means that copper wire can be used for various purposes. For example, if you need a high-temperature application such as welding or soldering, you can use a higher grade of copper wire with a higher melting point
