Technology and Efficiency

The market for computer products is a multi-billion dollar business where one can find a perfect balance of technology and efficiency. The huge industrial market is lead by such names as IBM, Hewlett Packard, and Compaq. The steps that are taken to bring the computer from several small components to a desktop product are organization of the manufacturing facility, assembly of hardware, installation of software, and a test process. The production of a high quality product is important to computer buyers. Manufacturing factories produce approximately 14,000 systems weekly. Companies generally use 2 methods of computer assembly. One method involves complete unit assembly by one person, the other being group assembly where several people construct a single computer (the latter method is known as assembly line production). When assembling a computer, there are 8 to 10 major components installed including the processor speed chip, the motherboard, RAM (Random Access Memory), diskette drive, modem or network card, video card, hard drive, sound card, and CDROM. Before the components are placed into the computer, each part undergoes an extensive testing process called “quality control” . Quality control ensures that faulty systems are not shipped. As an initial step, prior to the assembly process, an inspection of the outer case to ensure that there are no scratches or defects. The brand name and indicator labels are put onto the computer case at this time. Next the motherboard is installed and prepared for the processor chip. The chip (which is often a Pentium chip) is attached to the motherboard along with the RAM component. Once the chip and RAM are installed, the internal speakers and sound card are placed into the case. The hard drive, disk drive and CD-ROM drive are attached to the computer chassis. All these components are then attached to the motherboard with cables so that they may communicate with each other. Power supply is then applied to the computer and other additional components such as the video card, and modem are added near a final stage of assembly. After all these components are installed to create the finished ‘PC’, the unit is thoroughly inspected to ensure that all the cables connections are in place and all other defects are fixed. Inspectors also ensure that cables are in appropriate places so that they do not touch components. The CMOS (complementary metal-oxide semiconductorcircuitry for the memory and processor) is set up at this time. The top cover is placed onto the computer and it is shipped off for further testing. All companies differ in their testing of finished products. A common practice in most companies includes the 48-hour burn in period. After it, final diagnostic tests are completed to ensure all components are working well. If a computer is ordered with sound cards, speakers are attached to the unit and they also are tested. Mouse and keyboard components are tested manually by connecting a testing mouse and keyboard to the ports. The computer is then shipped from the manufacturing site to the distribution center. Here, additional tests are possible as computers are randomly checked and inspected. The computer is then further shipped to department or retail stores for sale to the consumer. In conclusion, the production of a computer from a number of components to a finished product is a complex procedure.(…) The usefulness of the computer and subsequent consumer demand for improved models will keep pressure on manufactures to build more efficient, high quality machines in future years.
