Resource summary

RAM, ROM, CPU
  1. ROM
    1. Once data has been written onto a ROM chip, it cannot be removed and can only be read. Unlike main memory (RAM), ROM retains its contents even when the computer is turned off. ROM is referred to as being nonvolatile, whereas RAM is volatile.
      1. Read only memory
      2. CPU
        1. CPU means a central processing unit
          1. The CPU is the part of a computer system that is commonly known as the 'Brains of the computer'.
            1. A typical CPU has a number of components. The first is the arithmetic logic unit (ALU), which performs simple arithmetic and logical operations. Second is the control unit (CU), which manages the various components of the computer.
              1. In a computer, clock speed refers to the number of pulses per second generated by an oscillator that sets the tempo for the processor. Clock speed is usually measured in MHz (megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses per second).
              2. RAM
                1. RAM is a type of data storage.
                  1. Random access memory
                    1. A random-access memory device allows data items to be accessed (read or written) in almost the same amount of time irrespective of the physical location of data inside the memory.
                      1. Ram is a type of computer memory that can be accessed randomly
                    2. Motherboard
                      1. a printed circuit board containing the principal components of a computer or other device, with connectors for other circuit boards to be slotted into.
