Download file to see previous pages The digital computer operations are done by logic circuits that are digital circuits. The outputs of such circuits can be regulated by the input conditions. The many processing data within the interior of the computer ought to work in a synchronized way. This is often achieved by regulating them with a steady oscillator that always acts as the oscillator.
The CPU is the main storage unit of the computer and sometimes can be referred to as the computer’s memory. Initially, it consisted of vacuum tubes, but later consisted of ferromagnetic cores with doughnut shapes. Data and programs are not always used in the main storage and can always be stored in secondary or auxiliary storage. While punched paper cards have this function, the main materials that are currently in use include flash disks, magnetic tape and flash memories. When compared to the RAM, these are quite cheap. Today, magnetic tape is used mainly for the storage of voluminous data or main backups. In optical and magnetic systems, the norm is similar. The disk drive also has a motor that can spin the optical head. The drives are designed in a number of forms (Knuth, 2003, p.69). The flash disks have nonvolatile memory, which can be reprogrammed or erased.
The central processing Unit (CPU): The circuitry and the motherboard must be powered. The CPU acts as the thinking process or the computer brains just like humans have their brains to process and relay information. The processors usually have a cooling unit that helps in reducing the heat within the computer. The computer usually gives its user all the necessary instructions during operation. The common processors have quad-cores (Knuth, 2003, p.76). The modern computers have at least two CPUs, which help in the power of processing and to optimize the potential.
The power supply: Just like humans need the energy to operate, the computers also need the power to operate. The energy ...Download file to see next pagesRead More
