HOW TO MAXIMIZE YOUR COMPUTER HARDWARE AND SOFTWARE RESOURCES
Computer optimization/maximization is the process of modifying a software/hardware system to make some aspect of it work more efficiently or use fewer resources. In general, computers may be maximized so that they executes processes more rapidly, or are capable of operating with less memory storage or other resources, or draw less power. Optimization will generally focus on improving just one or two aspects of performance: execution time, memory usage, disk space, bandwidth, power consumption or some other resource. This will usually require a trade-off - where one factor is optimized at the expense of others. For example, increasing the size of cache improves runtime performance, but also increases the memory consumption. Other common trade-offs include code clarity and conciseness.
COMPUTER HARDWARE RESOURCES
System resources are what allocate and setup your hardware components, helping hardware to work without causing issues with other hardware within your computer. System resources are setup by one or more of the below. • Interrupt Request (IRQ)
• Input/output (I/O)
• Direct memory access (DMA)
What is an IRQ?
Short for Interrupt request, IRQ is a signal that has a direct line to the computer processor, allowing it to stop the processor momentarily and decide what to do next. Every IBM compatible computer has a maximum of 15 IRQs and are prioritized in the computer according to the importance of the device. See IRQ Listing for a list of IRQs, which may be available or are currently used. What is an I/O?
Input Output (I/O) represents the locations in memory that are designated by use of various devices to exchange information amongst themselves and the rest of the PC. See IRQ Listing for a list of IRQs and I/O ranges. What is a DMA?
DMA, or Direct Memory Access, are pathways provided by the hardware to allow the hardware direct access to the computer's memory. See DMA Listing for listing of DMA channels.
MAXIMIZATION OF COMPUTER HARDWARE RESOURCES
What type of IT equipment do I need?
– Computers Types
How can a LAN be used in a small office and what are the benefits? – Using a single printer
– Setting up a central ‘file’ server
The Right Pc
A PC or Notebook?
- Require your work in more than one location?
- Don’t need the highest performance?
- Cost is not the biggest priority.
Notebook Specification Factors?
1.5GHz Centrino Pentium M, 256Mb RAM, 20 GB HD
Weight, Battery Length, Screen Size
(Wireless LAN / 802.11), Bluetooth
PC Specification Factors
Celeron 2.4, 256Mb RAM, 20 GB HD (for basic office apps)
Pentium 4 2.8, 512Mb RAM, 40 GB HD (for more advanced tasks / / multimedia / have many applications in use together)
Screen – Limited Space �� LCD, Work all day �� 17”+ Flat Memory – More for more applications at once
Hard Disk – Not less than 20GB- 40GB Preferred.
Graphics – Need only for Multimedia (Games/Video etc.)
Characteristics of the right PC
• Best Service and Support.
• Assurance of what you will get under the cover....
