Are there financial incentives to do it now?

Upgrade or buy a new one?
Figure out what you needMake a listCompare cost of upgrade to the cost of buying a new one and selling or donating your old computer
Computers will keep getting cheaper and faster

Upgrading software
Before upgrading, ask yourself, “Why?”
ALWAYS back up before upgradingOperating systems
Upgrading to latest versionReplacing with a different OS entirely
ApplicationsDisable virus protectionUpgrade only one at a timeRebuild desktop on Macs after upgrading
![Page 15: Upgrading Why should I upgrade? ßMake it faster ßMake it bigger ßRun the latest software ßDo you NEED or WANT an upgrade? ßAre there financial incentives.](https://reader035.fdocuments.net/reader035/viewer/2022062314/56649e445503460f94b38165/html5/thumbnails/15.jpg)
Overclocking / Clock Chipping
Speeding up MHz of the existing processor
Voids your warrantyCan cause overheating, processor failure
Not the same as replacing the processor, you either replace a crystal or add a chip that accelerates the processor

Safety precautions for upgrades
Power offGive yourself plenty of room to workGround yourself to reduce staticHold parts by their edgesKeep plastic, vinyl and Styrofoam away
Keep track of what and where you’re unplugging things
Pull the plug, not the cable

Without plug & play, you may have to move jumpers, flip DIP switches, or reconfigure existing devices

Important concepts:Bus width (in bits): How much data passes through the bus at one time.
Bus speed (in MHz): How fast data passes through the bus.
Latency: how long it takes between chunks of data.
Local Bus: bypasses the expansion bus, dedicated path to processing
Crosstalk: interference caused by magnetic fields in parallel wires
