11 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

12 All in One Examples

13 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

14 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

15 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

16 Tablets Touch Screen Good for email, internet browsing, games 7 to 10 screens Wireless Wireless + Cell Phone

17 Tablets Continued Multiple Operating Systems Android – new version every year Apple – new version every 2 years Consider commonality with smart phone

18 Evaluate the computer Processor Power -type, # of cores Memory size, type and expandability Hard Drive size and type Number of USB ports and types (USB 3.0) Other interfaces Firewire -Thunderbolt HDMI - Display Port Bluetooth Wi-fi

19 Processor Types Intel, AMD in Desktops and Laptops Dual core to 8 core Economy, Standard, Server classes, mobile Netbooks mostly use ATOM single/dual core processors Performance Ratings available in Windows 7 Good charts at and

20 Processors AMD Sempron Economy Athlon, Phenom, A8, A10 Standard Operton Server Intel Celeron – ExxxEconomy Pentium Core2, i3, i5, i7Standard Xeon Server Mobile versions operate at slower speed to reduce power

21 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 The i3 dual core, i5 quad, i7 four or 6 core

22 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

23 Memory DDR3 Speeds now 800 mhz to 1600 mhz 4gbs new minimum 4 to 8 gbs supplied with 64 bit OSs Check to see if all slots are full

24 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

25 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
