Everything You Need to Know Before Buying a Computer Common sense talk- money saving solutions Dr. Jan Pittman Vanderpool Email: vanderj@wlac.edu
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://www.pcworld.com/products/computers/desktops.html
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. • Review sites • http://reviews.cnet.com/laptops/ • http://www.notebookreview.com/
Definitions-CPU • CPU(Central processing unit)- This is the brains of the computer and its power is generally measured in clock speed (cpu cycles). Today’s CPU’s 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
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
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)
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
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.
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
Manufacturers • PCs are manufactured (assembled) by either 1st tier, 2nd tier or whitebox companies (53% of all systems sold) • 1st tier companies • HP www.hp.com • Dell www.dell.com • Toshiba www.toshiba.com • Lenovo www.lenovo.com • 2nd tier companies • Acer www.acer.com • Sony www.sony.com • Sharp www.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
