Measures of Central Tendency (Measures of Position) )مقاييس النزعة المركزية (مقاييس الموضع
1- Introduction
It’s a numerical measures used to measure the data
concentrate position or cluster. In general the data is
tend to be concentrated around a particular values.
The pins of a 8085 microprocessor can be classified into seven
groups.
1.Address bus
A15 – A8 at pin no. 28 to pin no. 21, it carries the most significant 8-
bits of memory and I/O address. The microprocessor can address
directly 65536 memory locations or 64k memory locations using 16-
address lines (A15-A0). Pin no. 28 to pin no. 21 give us the higher
order 8-bits of the address (A15-A8).
AD7–AD0 at pin no. 19 to pin no. 12 are used for dual purpose. It is
time multiplexed lower 8-bit address bus (A7-A0) and 8-bit data bus

Characteristics of Memory:
In the broad sense, a microcomputer memory system can be logically
divided into three groups:
1) Processor memory
2) Primary or main memory
3) Secondary memory
• Processor memory refers to a set of internal registers. These registers hold
temporary results when computation is in progress.
• Primary memory or the main memory is the internal memory to store both
program and data. The processor can access these memories directly.
Polar Coordinates
So far, you have been representing graphs as collections of points on the
rectangular coordinate system. The corresponding equations for these graphs have been
in either rectangular or parametric form. In this section, you will study a coordinate
system called the polar coordinate system.
