Internal memory in the computer is the memory that is directly accessible by the processor without accessing the input-output channel of the computer. The internal memory is accessed by the processor over the system bus. In the section ahead we will discuss types of internal memories in computers and we will also look at the technique of error correction for internal memory … [Read more...] about Internal Memory in Computer Architecture
Bus Structure in Computer Architecture
Bus structures in computer plays important role in connecting the internal components of the computer. The bus in the computer is the shared transmission medium. This means multiple components or devices use the same bus structure to transmit the information signals to each other. At a time, only one pair of devices can use this bus to communicate with each other … [Read more...] about Bus Structure in Computer Architecture
Parallelism in Uniprocessor
Parallelism in a uniprocessor means a system with a single processor performing two or more than two tasks simultaneously. Parallelism can be achieved by two means hardware and software. Parallelism increases efficiency and reduces the time of processing. In this section, we will discuss the structure of a uniprocessor system, and how parallelism can be promoted in the … [Read more...] about Parallelism in Uniprocessor
Interrupts in Computer Architecture
An interrupt in computer architecture is a signal that requests the processor to suspend its current execution and service the occurred interrupt. To service the interrupt the processor executes the corresponding interrupt service routine (ISR). After the execution of the interrupt service routine, the processor resumes the execution of the suspended program. Interrupts can be … [Read more...] about Interrupts in Computer Architecture
Memory Locations and Addresses
Memory locations and addresses determine how the computer’s memory is organized so that the user can efficiently store or retrieve information from the computer. The computer’s memory is made of a silicon chip which has millions of storage cell, where each storage cell is capable to store a bit of information which value is either 0 or 1. But the fact is, computer memory … [Read more...] about Memory Locations and Addresses
