Direct Memory Access (DMA) is a mechanism that allows peripherals to transfer data directly to and from the main memory without involving the central processing unit (CPU) for every data transfer. DMA enhances overall system performance by reducing the CPU’s involvement in data transfer operations and allowing it to focus Read more…
Programmed I/O operations are the result of I/O instructions written in the computer program. Each data item transfer is initiated by an instruction in the program. Usually, the transfer is to and from a CPU register and peripheral. Other instructions are needed to transfer the data to and from CPU Read more…
Modes of data transfer in Computer Organization and Architecture (COA) refer to the different methods by which data can be exchanged between the central processing unit (CPU) and peripheral devices. These modes serve specific purposes in managing data flow within a computer system. The primary modes of data transfer include: Read more…
I/O ports, or Input/Output ports, are specific addresses or channels used by a computer to communicate with peripheral devices. These ports are pathways through which data is exchanged between the central processing unit (CPU) and external devices such as keyboards, mice, printers, and storage devices. There are different types of Read more…
The Input/Output (I/O) interface is a crucial component that allows the Central Processing Unit (CPU) to communicate with peripheral devices. The I/O interface manages the exchange of data between the CPU and external devices, enabling input from devices like keyboards and mice and output to devices like displays and printers. Read more…
In computer organization and architecture, peripheral devices play a crucial role in facilitating communication between the computer and the external world. Peripheral devices are hardware components that are connected to the computer to provide additional functionalities and input/output capabilities. These devices extend the basic capabilities of the computer and Read more…
Addressing modes are techniques used to specify the memory address or data location that an instruction should operate on.These modes define how the CPU interprets the operand (an input or output value) part of an instruction. MOV B, A [Here MOV is operation and (B & A) are Read more…
BCS302: Registers in Computer Architecture| Types of Registers Registers are essential components of the CPU in computer organization, serving as temporary storage for data and control information. There are several types of registers, each serving a specific purpose within the central processing unit (CPU). These registers facilitate various operations, including Read more…
A Modern Approach to Verbal & Non-Verbal Reasoning: In today’s fast-paced world, the ability to reason effectively is a crucial skill. Whether you’re preparing for competitive exams, enhancing your problem-solving skills, or simply seeking to improve your cognitive abilities, a modern approach to verbal and non-verbal reasoning can make a Read more…
Bus arbitration is the process of determining which component or device in a computer system gets access to a shared bus when multiple components want to use it simultaneously. This is crucial to ensure that different parts of the computer can communicate with each other efficiently and avoid conflicts. Here Read more…
