Microprocessor components. Light micrograph of an Intel Pentium microprocessor's clock driver, code cache and instruction fetch units. The clock driver regulates all the internal operations by the central processing unit (CPU). The cache memory (SRAM) stores data so that future requests can be served faster. In the instruction fetch unit the instruction is fetched from the memory address. The chip was fabricated by photolithography, using several overlapping metalization layers and vertical contacts to interconnect them in a mono-crystal silicon wafer, which serves as the substrate. Magnification: x22, when printed 10 centimetres wide.

CCD camera sensor. Light micrograph of a close-up of a CCD (charge-coupled device) sensor from a digital camera. This sensor is responsible for converting light from the camera lens into the electronic image. It is a 2-D array of metal oxide semiconductor (MOS) capacitors. Magnification: x90, when printed 10 centimetres wide.

Computer RAM module. Light micrograph of a 1 megabyte fast page mode dynamic random-access memory (FPM DRAM) module. Random-access technology allows the computer's central processing unit (CPU) to read and write data very quickly. The chip can reach very high densities of storage and is therefore generally used as the main memory in personal computers. Magnification: x45, when printed 10 centimetres wide.

Circuit board. Underside of a PCB (printed circuit board). A PCB consists of lines (dark blue) of a metal conductor printed on an insulating material base. The metal lines form a circuit that connects the electronic components which are added to make a functioning device. The components are plugged into the board with pins that are held in place by solder (shiny round lumps), a soft metal that can easily be melted for this purpose. Circuit boards are used in most electronic products, including computers. This is a circuit board that is used in a video tape recorder. The triangular symbols (centre right) indicate the presence of electronic components called diodes.

Computer circuit board graveyard. Conceptual computer image of outdated computer circuit boards in a desert landscape, representing the obselescence of technology. The continual increase in computer power means that components rapidly become outdated and need to be disposed of or recycled.
