4. Definitions-Desktop Desktop computer-May consist of five or more components; – Main frame which houses the CPU, memory, permanent storage, DVD or CD drive, video adapter, sound adapter, Ethernet connector, keyboard, mouse, speakers and display – Non-portable configuration whose components may weigh more than twenty pounds Review sites – http://reviews.cnet.com/desktop-computers/ http://reviews.cnet.com/desktop-computers/ – http://www.pcworld.com/products/computers/desktops.h tml http://www.pcworld.com/products/computers/desktops.h tml

5. Definitions-Laptop (Notebook) Personal computers designed for mobility in five broad categories as defined by size & weight; – Netbook/Subnotebook: <10.5" x <1.5" x <1.3" @ <3.5 lbs – Ultraportable: 9-11" x 8-10" x <1.5" @ 2.0-5 lbs. – Thin and light: 11-15" x <11" x 1-1.7" @ 5-7 lbs. – Desktop Replacement: >15" x >11" x >1.5" @ >7 lbs. – Luggables: >18 x >13 x >1.5 @ >12 lbs.

6. Definitions-CPU CPU(Central processing unit)- This is the brains of the computer and its power is generally measured in clock speed (cpu cycles). Todays CPUs clock speeds will exceed 2 GHz on desktops and 1.6 GHz on laptops. Caveat-Rated clock speeds are not linear measurements- a 3.0 GHz P4 is actually less powerful than a 2.0 GHz Core 2 Duo

7. Definitions- Memory Memory (RAM)- non permanent storage measured in megabytes (MB) or preferably, gigabytes (GB). Desktops should have at least 2 GB of RAM while laptops may have 1 GB but should have 2 GB of RAM Caveat- Windows XP can only recognize 3.28 GB of RAM. Anything more is wasted. Windows 7 (32 bit) can recognize 4 GB and Windows 7 (64 bit) can recognize 192 GB

8. Definitions-Storage Permanent Storage (Hard drive) – Unlike RAM, data stored in permanent storage remains after the power is turned off. Storage, like RAM, is measured in gigabytes (GB). Desktops should have at a minimum 500 GB of storage while laptops may suffice with 250 GB Caveat- If you plan to store pictures, videos or music, you should opt for as much storage as possible (terabyte plus)

9. Definitions-Display Desktop display (monitor) – New systems should have an LCD flat panel display of at least 19 diagonal with a minimum resolution of 1280 x 1024. Higher is better. Laptops display – Depending upon the size laptop the screen dimensions will vary from 7 to 19 (too heavy) Minimum resolution of 1280 x 1024 Caveat- The video card must have its own fast processor and enough memory to support active screens

10. Definitions-Display Screen size – The screen size is the measurement of the displayable area of the screen from the lower corner to the opposite upper corner of the display (7-20 notebook, 15-30+ desktop) Aspect ratio – The aspect ratio refers to the number of horizontal pixels to vertical pixels in a display. Traditional displays used a 4:3 aspect ratio. Most new widescreen monitors use either a 16:10 or 16:9 aspect ratio. Native resolution – All LCD screens can actually display only a single given resolution referred to as the native resolution. This is the physical number of horizontal and vertical pixels that make up the LCD matrix of the display.. Contrast ratio – Basically a higher contrast ratio will mean that the screen will tend to have deeper blacks and brighter whites. Connectors – Most LCD panels have an analog and a digital connector on them. The analog connector is the VGA or DSUB-15. The common digital interface is the DVI connector. Stands – Many people don't consider the stand when purchasing a monitor but it can make a huge difference. There are typically four different types of adjustment: height, tilt, swivel and pivot.

11. Operating System Windows is the predominant operating system found on PCs – Windows XP-released October 30, 2001 and is currently the most widely installed PC operating system (est. >400 million worldwide) – Windows Vista-released January 30, 2007 and has been plagued by problems ever since its release – Windows 7- released October 22, 2009 purportedly to fix all past mistakes (installed on all new, major brand computers) Mac OS X-current version code named Snow Leopard

12. Manufacturers PCs are manufactured (assembled) by either 1 st tier, 2 nd tier or whitebox companies (53% of all systems sold) – 1 st tier companies HP www.hp.comwww.hp.com Dell www.dell.comwww.dell.com Toshiba www.toshiba.comwww.toshiba.com Lenovo www.lenovo.comwww.lenovo.com – 2 nd tier companies Acer www.acer.comwww.acer.com Sony www.sony.comwww.sony.com Sharp www.sharp.comwww.sharp.com – Whitebox companies Your local computer store Caveat- Buyer beware; smaller stores may not be there when you need them but conversely, may be able to provide you with personalized service when you want it
