Buying a Computer Comparing Computer Ads

Step 1 - ProcessorComputer #1 – Intel Pentium Processor E5300

Computer #2 – Intel Pentium Processor E2220 Computer #3 – Intel Core2 Quad Processor Q8200

Processor – (also known as CPU)• The clock speed of the processor measured in Mhz and now Ghz determines how fast the computer can operate.• In general the faster you can buy the better

Some Different Processors:• Intel – Pentium (III, IV) and Celeron• AMD – Athlon, K-6 and Duron• Via Technologies – MII and Cyrix


Step 2 - RAM

First, how computers understand size

Byte = 1 CharacterKilobyte = 1000 Bytes (1000 characters)Megabyte = 1000 Kilobytes (1,000,000)Gigabyte = 1000 Megabytes (1,000,000,000)Terabytes = 1000 Gigabytes (1,000,000,000,000)

Step 2 - RAM

RAM – Random Access Memory• The memory the computer uses while operating• In general the more RAM the more programs the

computer can run simultaneously• Computers will generally come with between 64 and 256mb of RAM (Get at least 64, though 128 is better)• DRAM – Current Standard• SDRAM (Synchronous DRAM) – Faster (Set to work with computer clock speed)• RDRAM (Rambus DRAM) – Even Faster

Computer #1 – 3GB SDRAMComputer #2 – 3GB SDRAMComputer #3 – 6GB SDRAM


Step 3 – Hard Drive SpaceComputer #1 – 400Gb Hard DriveComputer #2 – 500Gb Hard DriveComputer #3 – 750Gb Hard Drive

Hard Drive Memory• The computer’s long term memory• The place where computer programs are stored as well as the documents, images, sound files you create.• Desktop computers will generally come with 300 to 500 GB of hard drive space. Some now have Terabytes.• Think of Hard Drive space like closet space (Can you ever really have enough?)


Step 4 - MonitorComputer #1 – 22” LCD Wide-screen MonitorComputer #2 – 20” LCD Wide-screen MonitorComputer #3 – 20” HD Wide-screen Flat Panel Monitor $150 extra

Monitor• General sizes: 15”, 17”, 19”, 20-25”• 20” Standard on low priced computers• Viewable area measured corner to corner• 17” has viewable area generally 33% bigger than 15”• Bigger the monitor the more space it takes up and the more it costs• Most computers use Cathode Ray Tube (CRT) like TV• Also Flat Screen (CRT) and Flat Panel (LCD) models• Flat Panel monitors newest, small footprint, more expensive, picture not as bright• Beware of dot-pitch – you want .28mm or less


Step 5 – CD, CD-R, CD-RW, DVD

CD: Plays CD music and installs programs from CDCD-R: Plays CD music, installs programs from CD, and allows you to record (burn) your own CDCD-RW: Plays CD music, installs programs from CD, and allows you to record and re-record CDsDVD: Plays CD music, install programs from CD, and Play DVDDVD-R: Plays CD music, install programs and allows you to

record (burn) your own DVDs

Note: DVDs will eventually totally replace CDs

Computer #1 – 16X DVD(+/-)R/RW 12X RAM Computer #2 – SuperMulti DVD Burner With LightScribe Computer #3 – Dual-Layer 16x DVD Burner


Step 6 – PrintersComputer #1 – Free HP4480 printer with purchase

Computer #2 – HP Deskjet All-In-One Printer $29.99 with purchase Computer #3 – None

• Printers are generally Inkjet or Laser types• Unless you run a small business get an inkjet• Ink costs are your greatest enemy• Printers are almost “given” with computers, if not included a printer shouldn’t cost you more than $200 if you just want basics


Step 7 – Can you Upgrade?

• Upgrade the Processor?• Memory Sockets• Expansion slots• Ports• Expansion Bays• Hard Drive or Storage


Step 8 –Internet Service and Modems

• Your computer will either need a modem or network card to connect to the Internet• Modem’s are most common and use your phone line to connect• Modem’s are standard equipment and most computers will come with a V90 56K modem• Network cards are used to connect to cable systems and LANs• Many computers will come with a year free service• Some come with rebates for signing up for long term service

Computer #1 – 56k; Computer #2 – 56k; Computer #3 – 56k;

Buying a Computer Software

Software=Programs=Applications (Generally)Most computers will come prepackaged with enough software to get you started

In general you’ll get:• An Operating System (OS) – Windows 98/XP/VISTA• An “Application Suite” such Microsoft Office – Word Processor, Spreadsheet, Database• Internet Connection Software• Some basic games

Buying a Computer Warranties and Service

• Most major companies will provide you with at least one year of service and parts warranties• Most retailers will try to sell you long term warranties (that’s how they actually make money)• Do you need a long term warranty? In most cases NO• IF the computer might get used (read abused) it might be a good idea (Read: if you have little kids, buy the warranty)• Also, check into the credit card you use, you might get an additional warranty on purchases.• A note on service: if it’s not convenient for you, it’s no good

Buying a Computer Where to Buy?

• Computer Superstores – Perhaps best shopping; fairly knowledgeable staff; Decent Service; beware of long term warranties• Electronics Superstores – The person who sold stereos yesterday might be selling computers today; beware of long term warranties• Home-Office Superstores – Usually smaller higher end computers; salespeople not experts• Warehouse Clubs – Generally cheap, non-brand name computers• Mass Merchandisers – like Walmart; Generally lower end machines• Catalog or Online Retailers – Best prices but might have to mail the computer in for service• Local Computer Stores – Can be good for service, but watch out for mixed components
