Performance Factors of PCs and Monitors depends on RAM and Microprocessor

 Performance of a computer depends mainly on:
• Storage Capacity of RAM
• Speed of the microprocessor
Speed of the Microprocessor
• A microprocessor performs the actual processing of data
• Manipulates 8, 16 or 32 bits of data at a time
• PC with 32-bit microprocessor will be faster than 16-bit and the PC with16-bit microprocessor will be faster than a 8-bit system
• The Bus transfers data between the microprocessor, memory and peripherals
Storage Capacity of RAM
• The amount of RAM required depends on the applications you run on your computer
• Reasonable performance today calls for 128 MB
• You need to increase the RAM capacity to run multiple applications at the same time or work with large files
Clock Rate
• It is the fundamental rate at which a computer performs its most basic operations
• The faster the rate, the quicker the microprocessor works
Performance Factors of Monitors 


Screen Resolution
• Key characteristic of computer monitors
• Refers to the number of pixels a screen can display within a given area
• A higher number of pixels would mean better clarity in the display
Vertical frequency of the monitor
• Is another important characteristic
• Indicates the number of images that can be put together per second
• A higher frequency means less stress for the human eye
• Bus
• Hardware component that carries data within and between the microprocessor, memory and peripherals
• Clock rate
• Fundamental rate at which a computer performs its most basic operations
• Microprocessor
• Component of the system unit that performs the actual processing of data
