There are many differences between the 8085 and the 8086/8088. Naming just a few...
If anyone has any more examples, please fee free to add to the list.
A: Because it can only control 8 bits of data.
the 8051 is a micro controller the buttons tell the 8051 to do something there is an ir led on an output bit of the 8051 that shines on the tv ir detector it pulses a code the tv knows or window fan, ac , vcr, dvd the other output bits are used to scan multiple buttons like the difference between a rotary and touch tone Phone ive seen them with tms1000 and z8 thermostats may have 68hc11 it has 8 channel a/d right on it circuit diagram is very trivial its all in how you pulse the led
The instructions used by Atmel 89CXX and 89CXXXX are the same or subset of 8051 microcontrollers.Fully static operation,flash program memory,less pin count andprecision analog comparator ( in case of 89C20510)are some of the attractions in going for these microcontrollers. Due to many similar features in the architecture and instruction and instruction set as that of 8051, it becomes possible for the 8051 designer to directly start using 89CXX and 89C20XX microcontrollers without any more efforts in learning these microcontrollers.
Yes, but you'll need way more detail than you can get from a simple answer. You need: The 8051 micro, an LCD interface the LCD, and software to get the 8051 to drive the LCD. You may be able to find a kit/project that already contains these items.
EA - External Access PSEN - Program store Enable ALE - Address Latch Enable RST - Reset WR - RD
architecture
The 8051 is a micro-controller series, basically a computer on a chip. A system based on the 8051 series micro-controller is simply that, a device or series of devices that operate under control of one or more 8051 micro-controllers.
constructed on a single chip is called micro processor constructed on a single board is called micro controller
how temperature is measured using 8051 micro-controler?

avr is high speed cmpar to 8051.in 8051 there are less number of instructions
internal and external memory
A: Because it can only control 8 bits of data.
89s51 and 89s52 both are same version of 8051 microcontroller
Micro controllers work on CMOS logic where the voltage levels are 0 & 5volts or 0 & 3.3 volts, whereas RS 232 protocols define voltage levels to be +12v & -12v. http://www.dnatechindia.com/index.php/Tutorials/8051-Tutorial/Serial-Communication-Basic.html

The difference is that those MCUs that start with 80 are romless, those with 87 use EPROM erasable by light
