This article mainly introduces "what is in the Linux rpm package". In the daily operation, I believe many people have doubts about what problems there are in the Linux rpm package. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about "what is in the Linux rpm package?" Next, please follow the editor to study!

There are often 64-bit, 32-bit, i386, i586, and so on in Linux's rpm package names, which makes people confused and don't know which one is appropriate. Let's figure out these concepts one by one.

64-bit, 32-bit refers to the operating system.

The operating system is just a platform between hardware and application software.

32-bit CPU design for 32-bit operating systems.

64-bit CPU design for 64-bit operating systems.

The count of 32-bit processors and 64-bit processors is a multiple of 8. It represents the number of binaries processed by the processor in a clock cycle. A 32-bit processor processes 32-bit data, or 4 bytes, per clock cycle, and a 64-bit processor processes 64-bit data, or 8 bytes.

2 to the power of 32 = about 4G, it is obvious that 32-bit CPU only has about 4G memory address space, for some servers, 4G memory is far from enough. The memory addressing space of 64-bit CPU is about 2 to the power of 64 = 120GB.

Use the command file / sbin/init or getconf LONG_BIT to see whether it is 32-bit or 64-bit.

I386: almost any X86 platform, whether the old pentum or the new pentum-IV and K7 system CPU, works properly, I refers to Intel-compatible CPU, and 386 is the CPU level.

I586: it is a class of 586 computers, including CPU such as CPU (socket7 pin), which is the first generation of pentum MMX CPU,AMD 's K5Magol K6 system.

The Intel system CPU after i686:pentum 2 and the CPU after K7 all belong to this class.

Noarch: stands for independent of hardware architecture. Whether it's x86, PowerPC,Sparc, or Alpha systems.

At this point, the study of "what's in the Linux rpm package" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
