We haven't used near and far addressing for well over a decade. It was common in older systems where memory was addressed by segment and offset. For instance, on a 32-bit system we might use 16-bits to address the segment and 16-bits to address the offset within that segment. If we were referring to an offset within the current segment then we'd use a 16-bit near pointer, but if we needed to refer to another segment then we'd use a 32-bit far pointer. Today we use a normalised pointers.

What is the difference between an elastomer and plastics?
There isn't too much of a difference between elastomers and plastics. The only real difference between them is how far you can stretch them. Other than that they are really similar.
What is the difference between near heap and far heap?
Near and far are obsolete terms used in the MSDOS and Windows 3.x platforms on the 8086/8088 processor. Near represents an area of memory that can be accessed using only a 16 bit offset and, as such, must lie within the default data segment, and is always less than 64kb in size. Far represents an area of memory that must be accessed using both a 16 bit offset and a 16 bit segment and, as such, can lie anywhere in memory and be larger than 64kb, at the expense of additional processing time and program size.
In highway engineering what is the difference between a grade separator and a flyover bridge?
There is no point of difference between grade separator or a flyover bridge.The point is that a grade separator can either be a flyover or an under pass, that is any structure which separates the uniform grade of a running highway into two different grades. Also considering the cost fact grade saperator is more cost effective as far as my knowledge.
What is the difference between a half wave rectifier and a negative clipper?
As far as general principles apply, they both perform the same function: using a diode.
What is the difference between magnetic pick up and proximity sensor?
A limit switch turns on or off when the object being sensed reaches a specific location.A proximity sensor returns an analog signal indicating how far the object is from the sensor.
What is difference between short and near jumps in Intel Microprocessors?
difference between short,near and far jump
What is the difference between near and far procedure in 8086 microprocessor?
Near calls and returns transfer control between procedures in the same code segment. Far calls and returns pass control between different segments.
What is the difference between near and nearly?
Near refers to place meaning not far away, but close; nearly (adverb) means almost.
What is the difference between near and next to?

What do photos of the far side of the moon show?
The crater shapes and shading is different but otherwise the same as this side. Comment: There's one big difference between the far side and the near side of the Moon. The far side lacks the "maria" which are such a feature of the near side.
What is the name of the internal structure of the eye that forces images to see far and near?
The internal lens
What is the reason of the time difference between Auckland and Johannesburg?
The reason they have a time difference, is because they are nowhere near each other! Auckland, New Zealand, is far to the east of Africa, and places that are located in different places as far as east and west, not north and south, have different timezones!
The difference between so far and by now?
There really is no difference but you can say that by now is saying "they should be here by now" . And so far is saying "I have $10 so far".
