IT Lesson #2 - Building a computer (Part #1)

IT Lesson #2 - Building a computer (Part #1)


This list of tasks is mostly related to hardware.
You must at least be able to understand what the basic components of computers do.

Basic physics:
    What are Hertzs , Megahertzs and Gigahertzs?
    What do they influence?

CPU-

     What determines the speed of processors?
     What is the difference between a 40nm (nanometer) processor and a 20nm one?
     Clock speed of a processor. What is it?
     Cores, what are they?
     What is a heatsink? Why do CPUs need one?


RAM - Types of Ram.

      What is DDR ?
      How does the different clock speed on Ram affect the processor?

Motherboard.

    What is a computer motherboard?
    Check the following concepts:
          Ram bus
          North bridge
          South bridge
          SATA controller
          IDE controller
              (The next module will be about storage, so don't go overboard with the last two points)
          Types of motherboard layouts

          ISA slot (legacy)
          PCI slot
          PCIe (PCI express slot) -- what are the different speeds?
         
Storage - we will cover this in the next module
PSU power supplies -- This will be covered in one of the next modules
Graphics cards -- Same thing here too.


Lab module - Design a Gaming computer!!

1.- Go to a website where they sell computer components

2.- Pick a combination of  CPU, RAM, Motherboard and Heatsink that can work together.

3.- You must be able to explain why you selected the particular components that you picked.

We will use these picks for the next module where you will learn what else to buy to complete the computer.

History section:

- Who is Linus Torvalds?
- Who was George Boole?


Have a nice week!! :-)

IT lesson #1 - Some basics

IT lesson 1:

1.- Search for the following terms and define them under your own words:

Difference between Hardware and Software

CPU

    What are: CISC and  RISC

    Differences between  x86, x64 & AMD64
    What are the different CPU manufacturers?

RAM
ROM
Hard drive
     Difference between SSD and HDD

2.- Read about the history of IT and its pioneers

- Charles babbage
- Alan Turing


3.- Practical:

- Find out how much RAM your computer has, what processor and what operating system (and version of it).
Also find out what type of persistent memory your computer has.
