Intel 8085A (simply 8085) is an 8-bit general-purpose microprocessor introduced by intel in 1977. It can address 64K Byte of memory. It has 40 pins. An 8085 Microprocessor requires a +5V power supply to operate. Its clock speed is about 3 MHz. Intel 8085 is an enhanced version of Intel 8080.

A priority queue is a collection of elements, in which each element has been assigned a priority value. The order in which the elements will be processed is decided by the priority of the element. An element with higher priority is processed first. If elements with the same priority occur, they are processed according to the order
Traditional computer CPUs was designed with components on various boards. With IC technology, it became possible to build the CPU on a single chip. A microprocessor is a CPU that happens to be on a single chip. A computer with a microprocessor as a CPU is known as a microcomputer. A microcontroller is an entire

Limitation of Linear Queue Look at the following queue. You cannot insert a new value now, because the queue is completely full. Consider the following case: two consecutive deletions are made. Even though there is enough space to hold a new element, the overflow condition still occurs since the condition rear = MAX – 1 is
A microprocessor (µP) is a multipurpose, programmable, clock-driven, register-based electronic device. It reads binary instructions from memory, accepts binary data as input, processes data according to the instructions, and provides output. It is a complete processing unit with necessary control signals. Reads binary instructions from memory. Accept binary data as input. Process data according to

A Queue is a linear data structure in which deletions can only occur at one end, known as the front, and insertions can only occur at the other end, known as the rear. It is similar to the real-life queue where the first person entering the queue is the first person who comes out of the
A computer is a programmable device that accepts data as input and process it with a set of instructions and produces the result as output. A computer consists of the following four parts, Input Unit. Output Unit. Memory Unit. Central Processing Unit. Input Unit The input unit accepts data and instructions from user. Digitise received

A function that calls itself is called a recursive function and this technique is called recursion. A recursive function will call itself until a final call that does not require a call to itself is made. It takes advantage of the system stack to temporarily store the calling function’s return address and local variables. There

Polish Notation Algebraic expressions can be written using three separate but equivalent notations namely infix, postfix, and prefix notations. Infix Notation The operator symbol is placed between its two operands in most arithmetic operations. This is called infix expression. For example, (A + B) ; here the operator + is placed between the two operands

A stack is a linear data structure in which an element may be inserted or deleted only at one end, called the top of the stack. That is elements are removed from a stack in the reverse order of insertion. Thus stacks are also called LIFO(Last In First Out) lists. The following figure shows a
