The original commercial version of Ethernet supported 10 Mbps bandwidth; the version introduced in the early 1990s supports 100

Elodia [21]

Answer: a) and c).

Explanation:

Ethernet is a Layer 2 and also Layer 1 Technology (this layer defines the technical details of cabling and connectors), so any upgrade to a newer, faster version (like 100G Ethernet) will be possible changing only the components operating at these layers, without changing anything in the higher layers like IP and TCP, for instance.

This is a direct consequence of the OSI layer model foundations, that say basically that each each layer is independent from the others, so the piece of software pertaining to one layer, only interacts with his layer peer in the destination machine.
So, any changes to the technology used in one of the layers, don't usually affect the operation of the other layers.

WARRIOR [948]

Answer:

Lexical rules that are defined in case of regular grammar are simple and the notation is quite easy to understand.

Regular expression are useful for defining constructs of identifiers or constants. e.g. a|b etc.

In the case of context-free, grammar is not simple and deals with the productions.

Context-free are useful in describing the nested constructs like if-else etc which are not defined by regular expressions.

These produce a higher level of reliability as it provides a medium for generating syntactical as well as semantic data. The grammar is context-free is a little complex.

When an object is falling because of gravity, the following formulacan be used to determine the distance the object falls in asp

ser-zykov [4K]

Answer:

True

Explanation:

When an object is falling under the influence of gravity, the distance of fall as a function of time is given by:

D(t)=ut + 1/2 * a * t^2

Where

u = initial velocity of the object ( = 0 in this case as the object is falling only under gravity),

a = acceleration of the falling object = g = 9.8 m/s^2 which represents the acceleration due to gravity.

Simplifying,

D(t) = 1/2 * g * t^2
