I was just a little bit confused about 32 bit v. 64 bit operating systems. What are the pros and cons of each and what does the "bit" thing actually mean?

32bit and 64bit mean, the amount of code / space it can handle. Usually 32b is for a Laptop and 64b is a PC.

With a 64 bit os you can use more ram, but sometimes the are less stable (windows xp 64 bit) or not compatible with very much stuff (Windows 7 64 bit) basicaly if you are using the computer at your house just go with 32 bit, unless you do a lot of mapping/ compiling / video editing.

In computer architecture, 32-bit integers, memory addresses, or other data units are those that are at most 32 bits (4 octets) wide. Also, 32-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 32-bit is also a term given to a generation of computers in which 32-bit processors were the norm. The range of integer values that can be stored in 32 bits is 0 through 4,294,967,295 or −2,147,483,648 through 2,147,483,647 using two's complement encoding. Hence, a processor with 32-bit memory addresses can directly access 4 GB of byte-addressable memory.
In computer architecture, 64-bit integers, memory addresses, or other data units are those that are at most 64 bits (8 octets) wide. Also, 64-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 64-bit is also a term given to a generation of computers in which 64-bit processors were the norm. 64-bit CPUs have existed in supercomputers since the 1970s (Cray-1, 1975; CDC 6000 series, 1964, were 60-bit) and in RISC-based workstations and servers since the early 1990s. In 2003 they were introduced to the (previously 32-bit) mainstream personal computer arena, in the form of the x86-64 and 64-bit PowerPC processor architectures. Without further qualification, a 64-bit computer architecture generally has integer and addressing registers that are 64 bits wide, allowing direct support for 64-bit data types and addresses. However, a CPU might have external data buses or address buses with different sizes than the registers, even larger (the 32-bit Pentium had a 64-bit data bus, for instance). The term may also refer to the size of low-level data types, such as 64-bit floating-point numbers.

Wow. I don't care if you copied it from wikipedia great answer! now I feel really lazy for not just doing it myself haha.

CPU architectures that based on 32 or 64 integer-long registers, address buses, or data buses.

Better operating system. Dude are you a geek or not? 64-bit goes further then galaxy!

half-answer:

X64 pro: -can handle more then ~3.25 GB of RAM; -the software writen in 64bit architecture will run faster (not necesarely 2 times faster then the 32bit).

con: -some apps (mostly on 32bit(X86) architecture) wont function correctly, the X64 system handles the binary code (ex:"011011100110") a little different then the 32bit(X86).

In layman's terms, 32bit gives you 32 lanes of a road, while 64 gives you 64 lanes.

Which is better? Well, it depends on your computer. I will never run a 32 bit OS natively on my laptop ever again. If you're using Linux, go 64. If you're using Adobe Flash or something else that was originally made for a 32bit OS, go with 32. Most 64 bit computers can run 32bit OSes just fine. Not vice versa.
