PC Or Apple Computer • PC • Multiple Vendors • Widest Hardware choices • Widest Price Range • More Software choices • 78% Market share • More training availability • More hacking attacks • Apple • Single Vendor • Better Integration • Fewer choices • Higher Prices • 3.7% Market share of PC/Laptops • Larger tablet share • Large Cell Phone share • More hacking attacks now, • But still less than PC • Operating system for tablet is • different than Mac laptop or • desktop
Desktop Most bang for the buck Cheapest and Easiest to Repair or Upgrade Widest choices Least likely to fail Cons Requires a lot of desk space
All in One Compromise between Laptop and Desktop Space of Monitor and Keyboard Available in multiple Monitor sizes Uses a standard size Keyboard Cons Medium repair cost Higher initial Cost Low upgrade ability
Laptop Smaller Size Prices have dropped Wide range of prices and features Cons Highest Repair Costs Highest failure rate but much improved Screen size Upgrade normally limited to memory and HD Battery costs
Laptops tradeoffs Screen size versus Battery Life and Weight Processor power versus Battery Life Video Power versus Battery Life Battery size options Web cam and bio-metric options Portability Cost versus power Wireless networking - bluetooth
Netbooks Laptops designed for the on the go crowd Max screen size 10.1 inches Low Power Processors Build in Wi-fi and sometimes cellular interfaces Reduced size keyboard Longer battery life Great for internet, email, showing pictures No CD or DVD May have Linux based Operating System

How to read Intel CPUs • There are 3 generations of the Core i3, i5, i7 families • For example i5-xyyy • If x is 7 or 6 then first generation • If x is 4 or 5 then first generation mobile • If x is 2 then second generation • If x is 3 then third generation • The yyy is the clock speed • http://www.hardwaresecrets.com/article/All-Core-i5-Models/943 • The i3 dual core, i5 quad, i7 four or 6 core
AMD CPU • FX-8xxx – fits AM3 sockets • A4-xxxx – Dual Core fits FM2 sockets • A6-xxxx – Tri Core ,FM 2 • A8-xxxx – Quad Core, FM2 • A10-xxxx – Eight core, FM2
Memory DDR3 Speeds now 800 mhz to 1600 mhz 4gbs new minimum 4 to 8 gbs supplied with 64 bit OS’s Check to see if all slots are full
Internal Hard Drives • SATA 2 is std, SATA3 new (twice as fast) • 3.5” for Desktops, 2.5” • Sizes from 300 gigabytes to 3 terabytes • RAID capability allows additional Hard Drive to be added for doubling speed or reliability or size • SSDD – Solid State Disk Drive - faster • PCI-e SSDD - fastest • SATA has replaced IDE drives
Monitor • CRT – Oldest technology 17” -120 watts • LCD – Still very popular - 12 watts • LED – Newer technology – 6 watts • Wide Screen – 16/9 width to height ratio • Great for movies and spreadsheets • older screens were 4/3 ratio • Watch for types and numbers of interface – VGA, DVI, HDMI, Display Port • External Touch screens – use USB to transfer touch data – expect bluetooth • in future
