Memory is an essential component of any microprocessor-based system. the memory stores the data and instructions for the microprocessor. these are different types of memories. The Read/Write memory is made of registers and each register has a group of flip-flops. the flip-flops are named memory cells. the number of bits stored in a register is…
For economic use of pins of microprocessor 8085, the lower order address bus is multiplexed with the data bus. this is known as multiplexed Address/Data Bus (AD0 – AD7). the microprocessor 8085 provides an address during the earlier part of the execution of an instruction on the multiplexed bus (AD0 – AD7). data is also…

The 8085 microprocessor is an eight-bit microprocessor. It is a single-chip, NMOS device implemented with 6200 transistors in a 40-pin dual-in-line package. It operates on a single +5V power supply with a maximum of 3 MHz clock frequency. Below given (a) figure shows the pin configuration and (b) shows the function pin diagram of the…
The 8085 microprocessor can perform various operations on the given data by selecting necessary instructions from its set. these instructions are stored in memory. the microprocessor reads (fetches) one instruction at a time. interpret it with the help of the instruction set library and performs the data manipulation indicated by the instruction. the result can…
8085 Microprocessor is an 8-bit general-purpose microprocessor. It is suitable for a wide range of applications. It is called an 8-bit microprocessor because it has an 8-bit internal data bus and can read, write and process 8-bit data at a time. The internal architecture of the 8085 microprocessor is shown below figure. This includes the…
The microprocessor is a multipurpose, programmable logic device that reads an instruction from a storage device called memory accepts binary data as input and processes data according to those instructions and provides results at the output. In a broad way, a digital circuit that has computing and decision-making capability is structurally designed in such a…
The most common Number system arithmetic operations are addition, subtraction, multiplication, and division. we all are familiar with these arithmetic operations on decimal numbers. the same operations can be performed on binary, octal, and hexadecimal numbers. Binary Arithmetic Binary arithmetic is much simpler than decimal arithmetic because here only two digits, 0 and 1 are involved….

In a digital computer everything, whether it is some data, result, or instruction, has to be represented using only 0s and 1s. This is because the digital computer basically uses transistors that are made to work in the ‘OFF’ state or in the ‘ON’ state. The ‘OFF’ state is generally represented as the logic ‘0’…
Some of the semiconductor chips are needed to connect peripherals to the system bus. these chips are called interfacing devices. all peripherals and memory share the same bus, however, the microprocessor communicates with only one peripheral at a time. for the proper functioning of this system, tri-state logic devices are necessary. Types of Interfacing Logic…
Computer Structure is a lead for an operating system where we are arranging the functional things in a way to create a structure of an operating system is called Computer Structure. a structure of a computer consists of the Operating system, Hardware, software, firmware, input-output devices, Memory and storage classes. Operating System The operating system…
Languages are defined as communication skill which is used to interact with any person or device. The skill should be such that a proper interaction could be established between the two communicating persons or a person and a device. The microprocessor is a programmable device that recognizes and operates in binary numbers (0’s and 1’s)….
Computer systems have undergone many changes recently. The invention of microprocessors with IC technology reduces large machines to small desktop computer systems. A number of computers are available with the same basic functions but all of these are not the same. computer systems can be categorized according to the application for which it is designed….
