slide15

Buying a Computer

Comparing Computer Ads Step 1 - Processor

Computer #1 – Celeron 800Mhz

Computer #2 – Celeron 900Mhz

Computer #3 – Pentium IV 1.6 Ghz

  • 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
slide16

Buying a Computer

Comparing Computer Ads Step 2 - RAM

First, how computers understand size

Byte = 1 Character

Kilobyte = 1000 Bytes (1000 characters)

Megabyte = 1000 Kilobytes (1,000,000…)

Gigabyte = 1000 Megabytes (1,000,000,000…)

slide17

Buying a Computer

Buying a Computer

Comparing Computer Ads Step 2 - RAM

Computer #1 – 128mb RAM

Computer #2 – 128mb SDRAM

Computer #3 – 128mb RDRAM

  • 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
slide18

Buying a Computer

Comparing Computer Ads Step 3 – Hard Drive Space

Computer #1 – 20Gb Hard Drive

Computer #2 – 30Gb Hard Drive

Computer #3 – 40Gb 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 16 to 75Gb of hard drive space.
  • Think of Hard Drive space like closet space (Can you ever really have enough?)
slide19

Buying a Computer

Comparing Computer Ads Step 4 - Monitor

Computer #1 – 15” Monitor

Computer #2 – 15” Monitor 13.8” Viewable

Computer #3 – 17” Monitor 15.9” Viewable

  • Monitor
  • General sizes: 15”, 17”, 19”, 20-25”
  • 15” 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
slide20

Buying a Computer

Comparing Computer Ads Step 5 – CD, CD-R, CD-RW, DVD

Computer #1 – 48X Max CD-ROM drive

Computer #2 – 48X Max CD-ROM drive; 8x Max CD-RW

Computer #3 – 48X Max CD-ROM drive; 8x Max CD-RW

CD: Plays CD music and installs programs from CD

CD-R: Plays CD music, installs programs from CD,

and allows you to record (burn) your own CD

CD-RW: Plays CD music, installs programs from CD, and

allows you to record and re-record CDs

DVD: Plays CD music, install programs from CD, and Play DVD

Note: DVDs will eventually totally replace CDs

“Recordable” DVD is here but very expensive…price will

come down

slide21

Buying a Computer

Comparing Computer Ads Step 6 – Printers

Computer #1 – Compaq Color Printer

Computer #2 – HP Color Printer

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
slide22

Buying a Computer

Comparing Computer Ads Step 7 – Can you Upgrade?

  • Upgrade the Processor?
  • Memory Sockets
  • Expansion slots
  • Ports
  • Expansion Bays
  • Hard Drive or Storage
slide23

Buying a Computer

Comparing Computer Ads Step 8 –Internet Service and Modems

Computer #1 – 56k; 1yr MSN

Computer #2 – 56k; 1yr MSN

Computer #3 – 56k; 1yr AOL

  • 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
slide24

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 95/98/ME/XP
  • An “Application Suite” such Microsoft Works – Word Processor, Spreadsheet, Database
  • Internet Connection Software
  • Some basic games
slide25

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, but 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
slide26

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 Kmart and 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
