The Modern Computer

Question 1

Introduction to Computer Hardware

Answer 1

1 - CPU is the brain of the computer
2 - RAM is the short term memory
3 - Hard drive is the long term memory
4 - Motherboard is the body or circulatory system that connects all the pieces together.

Question 2

Programs and hardware(1)

Answer 2

1 - Programs are basic instructions that tell the computer what to do (ex: apps).
2 - we store programs on a durable media like hard drive and copies in a RAM
3 - CPU not only execute faster than it can read, but it also execute line by line.
4 - External Data Bus are rows of wires that function like voltages in an on/off state (1s and 0s).

Question 3

Programs and hardware(2)

Answer 3

5 - Inside the CPU is a component called Registers. they let us store info on the CPU that can be accessed quickly (ex: 2 numbers would go to registers a and b).
6 - MCC (Memory Controller Chip) is the bridge between CPU and RAM. it grabs the address in RAM and gives it to the EDB (address Bus), which is the gap between MCC and CPU. ( RAM - MCC - EDB - CPU).
7 - Cache (smaller than RAM) stores info that can be accessed often and quickly. It goes from L1 ( smallest and fastest) to L3.
8 - Internal clock is used by CPU to know when to end/start new task. Clock speed is the max number of clock cycles it can handle in a set period of time.
9 - Clock cycle is when you send a voltage to the clock wire to signal end of task..
