My laptop has a dual core processor, what is the difference between it and a single core

Surfing the internet is expensive, right? I've used it before; (A few thousand dollars a month.)

Let's get an adsl monthly subscription, save worry and money.

The biggest difference between dual-core and single-core is that dual-core has a great advantage over single-core when dealing with multiple programs running at the same time, and the speed is faster. For example, when you run a large game, you can do the transcoding while doing it, and the single-core one is basically ineffective (depending on the configuration). It's like 1 person can have 2 brains and do 2 things at the same time, without affecting each other.

First of all, you don't know much about the computer, simply put, the computer runs a program instruction that is executed, the single-core is a processor to execute the instructions, and the dual-core is 2 processors to execute the instructions, the two cooperate, the processing speed is faster than the single-core one, if the single-core executes 4 instructions per unit of time, the dual-core will execute 8 instructions, anyway, the internal architecture says that you don't know, the dual-core is the integrated dual-core, the single-core is a core, The dual-core ones are faster than the single-core ones.

For the 2 network connections on your computer, the local connection is the network card, which is used to access the Internet; 1394 connection,If I'm not wrong,It's supposed to be the connection of the IEEE1394 interface of the home DV camera,It doesn't seem to have anything to do with the network.,As for the 2 connections you said, you have to fill in the IP.,I don't know that the 1394 connection also needs to be filled.,I haven't used 1394.,I've never seen it.。 You can just fill in a local connection now, and you will have no problem surfing the Internet.

As for the fastest network speed, it is not a personal can be improved, it depends on the size of the bandwidth of the network you are involved in, and furthermore, if you really want to improve the network speed, you can use the optimization master to optimize your computer's network, so I don't know if it can, I don't think there is much change in my use, another method, what I can see from the Internet, is to enter in the start menu "Run", open the "Group Policy" machine, select "Local Computer Policy" -- Computer Configuration -- Management Template -- Network -- QoS Packet Scheduler", select "Limit Retained Bandwidth" in the window on the right, right-click "Properties", select "Enabled", and then change "Bandwidth Limit" to 0%, which seems to liberate the 20% bandwidth reserved by Windows, but it seems that it has not changed since I used it. In short, you can surf the Internet normally, and the speed is not particularly slow, and you are content.

The difference is still very simple, dual-core is two cores, and four-core is four cores. It can also be seen from the numbers that the quad-core one is larger than the dual-core one, so it must be that the quad-core one is better. However, it does not necessarily mean that the more cores, the better.

This still depends on the main frequency of the CPU, in general, the higher the frequency, the faster the running speed. Sometimes the dual-core will not run slower than the quad-core. So now the mainstream on the market is still dual-core, for example, Intel's current i3 and i5 processors are dual-core, but the i5 processor has an overclocking technology, and the i3 does not have this technology. Without this technology, the i3 and i5 would be actually the same. Then i7 is different, this is pure four cores, this is the running speed is faster, although the frequency is lower, but the core is more powerful plus overclocking.

AMD and Intel In comparison, these two companies both produce CPUs, but there is a big difference in system and process, AMD's quad-core processor is not as stable as Intel's processor dual-core, and the efficiency is not very high. This is again about the process and technology.

In short, in a word, Intel's dual-core is definitely better than AMD's quad-core, and Intel's quad-core is definitely better than Intel's dual-core.

It is equivalent to the difference between the speed of 20 miles and 40 miles.

The processor runs faster.

The general inter is 2 cores, and AMD is mostly 4 cores, the difference! Civilian households can't feel it, but the main frequency can be more direct.
