3.2 32 or 64?

✅ 32 or 64 can mean two things

When we say 32 or 64, we can be talking about two things

1. The architecture of my motherboard

• factory settings of the motherboard
• unchangeable
• architecture of a system cannot be modified. ❌

2. Type of Operating System

• the OS can be 32 or 64 bits
• changeable

✅ The architecture of my motherboard

☑️ 32 bits architecture = x86

• We say that my architecture is 32 bits when all the buses transmit 32 bits in parallel
• buses of the motherboard has 32 bits
• Parallel means: at the same time
• like a 32 lanes highway

✔️ RAM in x86

• If you have x-86, your RAM maximum would be <=4GB
• If the conections(bus) have 32 bits,
• you have 2 to the power to 32 positions on the RAM
• 2 to the power to 32 = 4GB of RAM
• ends with 8F, FFFFFFFF

• NOT file size, RAM size would be 4GB ❌

• ⚠️ If you insert more than 4GB, your RAM will not be read at all! 😱

✔️ Name of 32 bits architecture, x86

• The technical name of 32 bits architecture is called x86
• following the name of the first 32 bits architecture computer, intel 8086

✔️ What uses the x86 motherboard system?

• these days personal computers use x64
• but many servers still keep the achitecture x86

☑️ 64 bits architecture = x64

• We say that my architecture is 64 bits when all the buses transmit 64 bits in parallel

✔️ Name of 64 bits, x64

• The technical name of 64 bits architecture is x64 systems
• Some ppl also called x64 as x86-64, but recomment x64

✔️ Check before downloading

• When you download an application,
• you need to know if your computer is a x86 or x64

• from 2010, all computers are 64 bits

• ✔️ RAM in x64
• you have 64 bits for everything
• you have 2 to the power to 64 positions on the RAM
• 2 to the power to 64 = 16Exa of RAM
• end in 16F, FFFFFFFFFFFFFF
• this does not exist, but RAM would be 16Exa RAM

❓ Can a system with x86 read more than 4GB?
👉🏻 NO.

❓ I have a computer, when I install smth bigger than 4GB, I have an error. WHy?
👉🏻 Bc I my motherboard is using x86

✅ How to know the architecture of your motherboard

1️⃣ First way: MSINFO 32

windows + R > MSINFO 32 > System Type(Tipo de sistema)

• when you download, your tool should have the same architecture
• the tool of CPU-Z for System Analysis and Monitoring Windows systems
• this tool detects your architecture

2️⃣ Second way: systeminfo

Win+R > cmd > systeminfo

• systeminfo
• capture the terminal

✅ Type of Operating system

• modifiable
• applications inside the HDD

☑️ 32bits

• We say that OS has 32 bits if the Apps/Files of the Harddisk(secondary memory) have a maximum ofs4GB
• apps, files will have max of 4GB, not the RAM ❌

☑️ 64bits

• We say that OS has 64 bits if the Apps of the Harddisk(secondary memory) can have a maximum of 16Exa Bytes

✅ How to check my OS

1️⃣ on terminal: wmic os get osarchitecture

Win+R > cmd > wmic os get osarchitecture

• windows key + R
• type cmd
• in the terminal that appears, write wmic os get osarchitecture

2️⃣ visually

You could also do the visual way: Open windows explorer > This PC (Este Equipo) Double Click C

• open windows explorer
• go to this pc
• double click on C
• if you see two folders, your OS has 64bits
  • one folder than ends in x86, it will be for files less than 4GB
  • and the other folder would be for bigger apps

• if you see one folder, your OS has 32bits

• ⭐️ Review
• in a 32bits OS, you see only one program files
• in a 64bits OS, you see two program files
  • program files: for bigger applications, bigger than 4GB
  • program files(x86): for files that are less or equals to than 4GB

❓ Can I have a windows 11 or 32 bits?
👉🏻 Yes you can. All OS have 32 and 64 bits versions, including windows 11
- so, you can choose.

• the bigger the architecture, bigger the OS,
• 64 bit versions are always better, faster, more efficient

❓Do we have all version, version 32 and version 64 of all OS?

- windows 8 had 32, 64 versions, windows 11 also have both versions...
- all OS have two versions
- do not think that 32 bit OS is old and bad, its just another version of OS
- and also, 64bit OS does not mean new and good, just choose the OS version that suits your computer.
