We can write a multi-frame window and divide the window area at will.

<frameset rows="*,*,*"><frameset cols="*,*"><frame src="http://www.baidu.com"><frame src="http://www.csdn.net"></frameset><frameset cols="*,*,*"><frame src="http://www.sina.com"><frame src="http://www.hao123.com"><frame src="http://www.chinaunix.net"></frameset><frame src="http://www.taobao.com"></frameset>

1. When dividing several rows and columns, you can enter numbers, percentages, or *.

2. <frameset> nested <frameset> is a good way to divide windows. It feels like it tastes a bit Array

3. There are several <frame> Windows, so <frame> do not leave it blank.

Let's take a look at the running result of this Code: put six hyperlinks, so you know.

It was very calm to see six pages, but very small, loading is very slow. Therefore, the instructor told us that <frameset> is mostly used for background pages.

What is the frame sharding Technology for HTML windows?

Window Frame separation separates a browser document window into multiple windows. Each window can display an independent webpage file, and each frame (that is, the page) has its own url.

When a speech signal is added to a window and divided into frames, the frame length is N. The frame length is measured in seconds, and the window length is N. What is the unit? Is it time?

Here N is a habit, and it is the index data points.
Now we are talking about digital signals. Where can we see processing analog speech signals? The "signal" here is actually the discrete data after sampling.
N × Ts is of course the unit of time, in seconds.
F is the frequency, Ts is the second, and f is the natural unit of Hz.
