32-Bit vs. 64-Bit - What Are Bits? Why Are They Important?
Рет қаралды 482,900
Күн бұрын32-bit vs. 64-bit. Which is “better”? What are the differences? Heck… what are bits, anyway? All of these questions, and more, will be answered in today’s TidBytes video! For addition info, look below in the addendum…

ADDENDUM (additional information about this topic is here for you!)
1. Small correction on the vacuum tubes. I used them as a visual aid, but technically it's a dual triode tube, so it's not "1-bit" per se. But you get the idea. Additionally, there's always electricity in the tube when the computer is on. This particular tube works for like a gate.
2. BINARY MATH: Each binary digit represents a power-of-2 whole number. If you have a byte (8 bits), that means your first bit represents 1, your second represents 2, then 4, 8, 16, 32, 64, and 128. Keep in mind, the numbers increase right to left. If a “1” is present, that represented number is added. If a “0” is present, the number is not added. So, 00001100 = 12. 10000001 = 129. 11111111 = 255.
3. GB vs. GiB: In short…
GB is the user-friendly measurement.
GiB is the computer-friendly measurement because data sizes are based on power-of-two values.
Gigabytes (GB) and gibibytes (GiB) are different, but GiB are commonly referred to as GB in conversation. Some operating systems refer to a GiB as a GB. 1 GB = 1,000,000,000 bytes, but 1 GiB = 1,073,741,824 bytes (1024^3). This is because GiB (KiB, MiB, etc) use powers of 2-1, 2, 4, 8, 16, 32, 64, 128, 256, and so on. Since regular computers (not quantum computers, or anything like that) use binary, we need to add these numbers in base-2, so the computer actually knows what the heck is going on. Adding in base-10 is more user-friendly and clean looking, but base-2 is what binary math uses. This is why, depending on how your OS and hardware interpret file size, your “500 GB” hard drive may read as “465.66 GB” (which is truly GiB).

Originally, 8-bit 16-bit referred to the width of the data units (natively supported data type, data bus & registers) which often had different widths for the range of their addressable memory space (16, 20, 24 bits). Funny later on, processors got more & more fancier data units (32-bit, 64-bit, 80-bit, 96-bit data types but also vectorized 128-bit, 256-bit & now 512-bit data types) but increasingly simpler & condensed addressable memory space (at least the logical or virtual memory space is overwhelmingly 32-bit or 64-bit on modern processors (while physical addressable memory still has awry different limits)) so some folks switched from categorizing their processors from data units to the size of addressable virtual memory space for conveniance.

There are two triodes in the tube, each used as NOT gates. Additional circuitry can be used to create a Flip-Flop, which is a sort of flipable bit or bi-stable gate..

So, how does it work? Step 1: Record the entire session = 1 hour. Step 2: Share the recording with everyone = 2.5 hours. Step 3: Preview the video record with friends = 1 day. Step 4: Download the video and review the video even without an Internet connection = 40 seconds. In addition, it supports 4K video viewing, live streaming, use HDR, 120 FPS video recording, and works on 24/7, i.e. 24 hours and 7 days. However, outdated technology does not have this feature, but the latest technology does. Thank you for listening.

What about unix time and how we are running out of 32 bit time?
@carultch 4 жыл бұрын
The Unix time stamp is defined as a number of seconds since midnight on January 1st 1970 in the time zone of the UK, ignoring leap seconds, and assuming every day has exactly 86400 seconds. This is why you end up with date stamps in 1969, because the date somehow got stored as zero by mistake, and if your time zone is in the USA, 1/1/1970 at midnight in the UK, happened on 12/31/1969 (for me, it would happen at 7 pm on that day). Your computer translates the Unix time stamp according to your time zone and the history of leap seconds, in order to put it in a form that makes sense to you. So late December back in 69 is when Unix says it is the start of time. In the 2038, there will be another equivalent Y2K event, where 32-bit Unix times stamp runs out of capacity to store the time. It will occur on January 19th at 03:14:07 AM UTC in 2038. It will be 2^32 seconds since the time stamp began. 32-bit systems will think it is the 1970's again. If you have 64 bit capabilities, it will never run out of capacity to store the date and time stamp in any practical time scale for humanity, as it will be longer than the age of the universe thus far.

Vaccuum tubes are not 'switches' except when being operated in saturation mode. Most are used in 'linear' mode where the grid voltage modulates the flow from the Cathode to the Anode, and can have amplification in the signal. Many tubes had only a single 'triode' in them, but dual 'triodes' were added for compactness and utility.

Few current 64 bit processors actually have a physical 64 bit address bus, and can't address the max possible amount of memory possible for a 64 bit machine. The addressing registers may actually hold 64 bits, and such large address values may actually be used to support virtual memory (where the bulk of the actual data is held in disk storage rather than in physical memory). Also it's currently impossible to actually equip a computer with 2e64 bytes of memory (never mind what that would cost!).

A BIT anoraky but the tube (valve) you were holding was at first glance a 6DJ8 or similar. Whatever the actual model number it was a double triode for sure.

Does 64 bit means you can represent a bigger range of number? So therefore, you can have a bigger ram? Since a register can point to more possible addresses on the ram.

In video games consoles, I heard the number of bits(8 bit for nes, 16 bits for snes, etc) is the bus width between the cpu and the ram.

Amazing explanation but the only thing I didn't get was at 7:54. That doesn't make any sense for me. 32 bits are just 4 bytes. What's the actual operation going on there?

I guess I'm way too old but I remember Altair 8080 runing 8 bit hardware and software and you measured your RAM in kilobytes.

So do 64 bit processors have higher ipc than 32 bit processors(suppose they are made equivalent except for the bit architecture)?
@bryceforsyth8521 4 жыл бұрын
No, they just have larger internal buses, registers, etc.

@@bryceforsyth8521 I'm sorry I don't know much and didn't get the video properly but what do larger registers and internal busea? Do they allow storing more data that can be used at once in the processor or is it something else? And it doesn't give any ipc advantage?
@bryceforsyth8521 4 жыл бұрын
@@Naverdo The registers will store larger values in a 64 bit system than a 32 bit system, so indeed more data per register, which in turn would allow larger values to be operated on immediately if the ALU is large enough to handle it. Look to the MC68000 which was a 32 bit processor (in a sense), but had a 16 bit ALU and external bus. If anything having a larger ALU would cause the 64 bit system to have a disadvantage when it comes to IPC (due to propogation delays and such, It would be more challenging to achieve an equivalent IPC), however for every arithmetic instruction executed more data is handled. If you look to modern processors, many have larger registers than their 32 or 64 bit labels would suggest. Such registers are operated on by internal coprocessing elements and [such registers] would be treated as sets of smaller registers by the CPU itself.

I think 64 bit computers uses more memory too. Doesn't it? If you write a C program, a long double for example would take up 2, 4, 8 bits respectively on 16, 32, 64 bit processors (well, the size depends on the compiler, and if you cross compile a software for 32 bit x86 processors on your 64 bit x86_64 processor, it will use lesser memory than the 64 bit version). Not only it's in long double, but in everything. If you compile and run a program (GCC or clang permits it) to show the size of void: ``` #include "stdio.h" int main() { printf("%lu", sizeof(void *) * 8) ; } ``` It will show 32 on 32 bit CPU and 64 on 64 bit CPU Now consider that the Linux kernel is written in C, that would should use more memory that 32 bit system on a 64 bit system. The same should apply to other OS as well.
