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.
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.
my PC is working very slow
Usually referred to as a "sawtooth wave" because of its distinctive appearance on a graph or oscilloscope.This is the shape of the voltage used for the horizontal and vertical deflection signals that 'paint' aTV picture on the screen.
Yes, significantly so. If you think about it, a lot of your expended energy is being lost through 'vertical' movement when what really makes you go faster is 'horizontal' movement. The thicker tread tyres on your mountain bike will also slow you down due to increased rolling resistance.
In comparison to what? If we're talking production cars then no, it's not slow at all. In fact it's one of the quickest.
slow & long lasting
Vertical rectangle
If you ignore the effect of the air grabbing at it and only figure in gravity, then the horizontal component of velocity is constant, from the time the stone leaves your hand until the time it hits the ground. Makes no difference whether you toss it up, down, horizontal, or on a slant. Also makes no difference whether it's a cannonball, a stone, or a bullet.
The system will become slow ,Then always programme's will be hanged in this we know the system is affected .............
The first computer functioned very quickly, by comparison with the work of people trying to perform the same calculations. However, by comparison with modern computers, the first one was painfully slow.
Not sure what the comparison is here . . slower than what would be a good question.
