Actually By Default this is present in BIOS(ROM) and at the boot time Operating System loads it to the RAM.
The differences are given below: 80286 1. Low data bus width (16 bit) 2. Returning from protected mode to real mode is hard and complicated. 3. Small RAM/Memory 80386 1. High data bus width (32 bit) 2. Easy for 80386 3. Big RAM / Memory (Real memory = 4GB and virtual memory= 64TB)
8051: 16 bit Microcontroller on chip ROM( 8KB) and On chip RAM (128 bytes) two 16 bit timer/counter. four 8-bit ports for input/output fully duplex serial receiver/transmitter. no prefetching of instruction. 16 address pins 8086: 16 bit Microprocessor No on chip memory. memory is divided into two banks to increase the processing speed. prefetching of 6 bytes of instruction in a queue. 20 address pins
Machine shaper are practically used in shaping materials. The parts of the machine shaper are Ram, Table, Clapper Box, Tool head, Cross rail, Stroke Adjustment, Column, Base and Table supports.
It should actually be a N X 1 Bit RAM, wherein the length of the RAM is N blocks, each block being 1 Bit Wide. I think now, it wont need any more explanation from : Bageshwar P Narain
A metal-working planer is an industrial machine used to produce flat surfaces. A metal object to be machined (the work piece) is placed on a working surface known as the table, and secured to the surface with bolts, clamps, etc. Alternately, the work piece may be secured to the table via a vise. The table (with work piece attached) is moved back-and-forth under a stationary tool bit which cuts off the metal. When the stroke of the table under the tool bit is completed the table returns to the starting position and the tool bit moves sideways a small amount thus being ready for another cut of metal off of the work piece. On some planers the tool bit moves sideways at the end of the cutting stroke before the table returns to the starting position. A planer's table can be as small as 8 inches wide by two feet long up to a size on which you could park a very large truck. A planer's table back-and-forth action is somewhat similar to that of a metal working shaper except in the case of a shaper, the work piece is held steady on a table and the tool bit, mounted on a moving ram, moves back and forth over the work piece. When the ram (with tool bit) is in the rearward position the table moves sideways so the work piece is ready for another cut.
8086 does not have RAM or ROM inside it. However, it has internal registers for storing intermediate and final results.
8086 has 20 address lines. Therefore it can address 220 bits or 1,048,576 bits of memory, or roughly 1 MB (mega byte).
The main features of 8051 microcontroller are: i. RAM - 128 Bytes (Data memory) ii. ROM - 4Kbytes (ROM signify the on - chip program space) iii. Serial Port - Using UART makes it simpler to interface for serial communication. iv. Two 16 bit Timer/ Counter v. Input/output Pins - 4 Ports of 8 bits each on a single chip. vi. 6 Interrupt Sources vii. 8 - bit ALU (Arithmetic Logic Unit) viii. Harvard Memory Architecture - It has 16 bit Address bus (each of RAM and ROM) and 8 bit Data Bus. ix. 8051 can execute 1 million one-cycle instructions per second with a clock frequency of 12MHz. source : http://www.engineersgarage.com/8051-microcontroller
The 8086/8088 can address a maximum of 220, or 1,048,576, or 1 MB of memory.
When programs' application data and interrupt service routines are being executed they are held in a computer's main memory. The largest component of main memory is RAM.

Here, let me explain. "RAM" is random access memory. Imagine you have a big filing cabinet with a bunch of files. You can get through them, but too fast. So, you put some of those files on a table. On a table, you can move through them much quicker. That's kind of how a computer works. RAM is measured in GB, or gigabytes. The average computer has around 2-4 GB of RAM in it. Computers can have less or more RAM, depending on the age/specs of the computer.
close the notebook and place it upside down, preferable on a table. you will notice the ram compartment if you look well and unscrew the screws and there you have access to your ram sticks.
SDRAM
The 8086/8088 microprocessor has a 20 bit address bus, so the number of memory locations it can address is 220 or 1,048,576.
