Upgrading and Repairing PCs Quotes

“A modern PC is both simple and complicated. It is simple in the sense that over the years, many of the components used to construct a system have become integrated with other components into fewer and fewer actual parts. It is complicated in the sense that each part in a modern system performs many more functions than did the same types of parts in older systems.”

“In 1976, a new company called Apple Computer introduced the Apple I, which originally sold for $666.66.”

“When both NMOS and PMOS field-effect transistors are combined in a complementary arrangement, power is used only when the transistors are switching, making dense, low-power circuit designs possible. Because of this, virtually all modern processors are designed using CMOS (Complementary Metal Oxide Semiconductor) technology.”
― Scott Mueller, Upgrading and Repairing PCs

“MOSFETs can be constructed as either NMOS or PMOS types, based on the arrangement of doped silicon used. Silicon doped with boron is called P-type (positive) because it lacks electrons, whereas silicon doped with phosphorus is called N-type (negative) because it has an excess of free electrons.”
