MEMORY

Hi everyone, i have post the questions here, i hope you will like it. Tell me in the comments. video
MEMORY
    1. Everything in a computer's memory takes the form of BITS
    2. where the binary digit is stored? In the memory cell
    3. the memory cells can achieve two states, which? 0 and 1
    4. Files and programs consist on millions of bytes and this data is processed in the CPU
    5. List the three main characteristics in a memory: Size, cost and speed
    6. What is random access memory (RAM). Explain it in two or three sentences: The CPU give instructions to the RAM, and the RAm modify the information, in order to a command in short-term.
    7. when a transistor and capacitor stored electrical charge, what bit is stored? They store electrical charge when there is a 1
    8. list the two characteristics of a Memory cache:
      Are made up of 6 interlocked transistors and don´t need refreshing.
    9. RAM and cache can only hold memory as long as they are powered
    10. Types of long term storage devices:
      Magnetic storage, optical-based storage and solid-state drives.
    11. Explain how flash sticks (solid state) stores the data using floating gate transistors that store bits by trapping or removing electrical charges.
    12. Can you write in a flash stick over and over again? why?
Repeatedly wiring to floating gate transistors corrodes them, eventually rendering them useless.

Inside your Computer

INSIDE YOUR COMPUTER
A mouse is a simply pheripheral device that consists on a couple buttons and a system for detecting motion and distance you migth have an optical mouse that makes this mesurements with ligths and sensors. When you click the mouse, it send a message with information about its position, and the basic input/output subsystem control it and help the CPU from distractions. The CPU is the brain of the PC, that have to fetch instructions for memory and executing them. If you write 60 words in a minute, the CPU will process billion of instructions a second, also is use for all activities and programs. The programs were made by humans before, like Java, C++ or Phyton but now are making in bytes.
The CPU organizate the mouse click, sending signals of the mouse click to the memory subsystem. Each instructions are executed, and the CPU learns where the mouse click. The CPU needs the monitor to show the thing associated with the click.
