All television images are built from a single trace that scans the screen from left to right and also from top to bottom. The first line of the image is drawn at the top of the screen. The next is drawn immediately below the first and so on until the complete image has been displayed.

Why is the vertical scanning very slow in comparison to horizontal scanning?

Vertical scanning = Scanning all ports on one or more host ..and Horizontal scannig =scanning one port on many host. When someone is performing vertical scanning, he/she is interested in any open ports and launching an attack on it from a Database of vulnerabilities. The objective is to attack , no matter what kind of attack it is. On the other hand - horizontal scanning attempts to launch a particular type of attack , so it is interested in only a particular open port in different host. Vertical scanning has more number of ports to scan than horizontal scanning. Hence it takes more time - making it slower than horizontal scanning.

Why vertical scanning is required in TV?

All television images are built from a single trace that scans the screen from left to right and also from top to bottom. The first line of the image is drawn at the top of the screen. The next is drawn immediately below the first and so on until the complete image has been displayed. The trace then returns to the top of the screen and starts the process once more. In the days of cathode ray tubes, the trace would travel down the tube at a continuous rate so the horizontal lines were in fact sloped down slightly as they travelled across the screen. This constant downward movement is the vertical scanning of the image. LCD and plasma screens use the same signal but the notion of a vertical scan is less obvious. Each line is a discrete step rather than a smooth downward movement. In terms of the data stream that makes up the television signal, both horizontal and vertical scanning are present even though the displays draw images in a rather different method to CRT models.
