What is bus architecture?
In computer architecture, a bus (related to the Latin “omnibus”, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.)
What is the difference between single bus and multiple bus structure?
A multiple Bus Structure has multiple inter connected service integration buses and for each bus the other buses are its foreign buses. A Single bus structure is very simple and consists of a single server. – A bus can not span multiple cells. And each cell can have more than one buses.
What is the advantage of multiple bus architecture?
Multiple buses permit several devices to work simultaneously, reducing time spent waiting and improving the computer’s speed. Performance improvements are the main reason for having multiple buses in a computer design.
What is microprocessor bus structure?
The bus over which the CPU sends out the address of the memory location is known as Address bus. The address bus carries the address of memory location to be written or to be read from. The address bus is unidirectional. It means bits flowing occurs only in one direction, only from microprocessor to peripheral devices.
Which type of RAM is used in main memory?
There are two main types of RAM: Dynamic RAM (DRAM) and Static RAM (SRAM). DRAM (pronounced DEE-RAM), is widely used as a computer’s main memory. Each DRAM memory cell is made up of a transistor and a capacitor within an integrated circuit, and a data bit is stored in the capacitor.
Is RAM a permanent memory?
Because of its volatility, RAM can’t store permanent data. RAM can be compared to a person’s short-term memory, and a hard disk drive to a person’s long-term memory.
Does the type of RAM matter?
More RAM lets your CPU do its job, especially when you’re loading large video files and doing complex photo-editing work. For the most part, the faster your RAM speed is, the more likely you are going to have success working on large files. There is also a RAM rating system used specifically for these types of modules.
Is it better to have more RAM or faster RAM?
While RAM speed is important, it’s better to have more RAM than faster RAM. If you’re configuring your PC and have budget constraints, then you might find it economical to buy more RAM that’s rated at a slower speed than fewer, faster modules.
