RESOURCE MANAGEMENT 6.1.1

1. Identify the resources

   • PRIMARY MEMORY = all processed data and instructions have to be stored in the primary memory
     • connected directly to the CPU, fetch decode, execute cycle
   • SECONDARY STORAGE = ROM, HARD DISK, USB STICKS, DVD
     • hardware that provide data integrity, low cost, mass storage capacity and permanent storage
   • RAM = type of primary memory, all data and instructions can be altered at any time
     • SRAM = statics RAM
       • faster, more expensive, smaller quantities
     • DRAM = dynamic RAM
       • larger quantities, cheaper, slower
     • volatile - when power is turned off data is lost
     • RAM = random access memory
   • ROM = read only memory
     • non volatile, slower
     • holds critical instructions
     • common use = hold the Basin Input Output System (BIOS)
   • PROCESSRO SPEED = fetch, decode, execute cycle continuously as long as the computer is on
     • measured in MIPS (minion instructions per second)
     • clock rate = frequency of processor is running, indicator of processor's performance
   • BANDWITH = rate at which data can travel from SRAM to DRAM to the processor and vice versa
   • screen resolution = all devices (televisions, phones, computers) have a maximum number of distinct pixels
   • sound processor = sound cards facilitate the input, process and output of audio signals

2. RESOURCES: primary memory, secondary storage, processor cores, speed of each core bandwidth, screen resolution, disk storage, sound processor, graphics processor, cache network connectivity

3. SYSTEM RESOURCES = components within a computer, both physical and virtual, that are available to be used by the operating system and other applications.

4. disk storage = generally category of metal or plastic storage plate on which data can be recorded

   • HDD (hard disk drive), FDD ( floppy disk drive), SSD (solid state drives) SSHD (solid state hybrid drives)

5. graphics processor - general purpose processors are not efficient at running demanding computer generated imagery algorithms

6. Network connectivity = process of connecting various parts of a network to one another
