Agenda Buying a computer What are your needs? Answer to last weeks question ‘What do I look for when buying a computer’
4
Buying a Computer So many options!! Desktop vs Nettop Vs Laptop vs Netbook vs Tablet Each person is going to have their own preferences Maybe even a couple of preference Choose the one that is right for you Few common things all computers share Components CPU RAM (Memory) Storage
5
Desktop Systems Monitor Case Keyboard, Mouse Extras Speaker, printers, joysticks
6
Desktop Considerations Advantages Easily upgradable components make it the best investment More USB ports Disadvantages Big Not very portable Can be noisy Can use a lot of power
7
Laptops vs Netbooks Laptop = Notebook Larger screen size More powerful hardware Netbook Smaller screen size Smaller keyboard Slower processor Limited USB ports
8
Laptop & Netbooks - Considerations Advantages Portable Allow for internet access anywhere there is a Wifi Connection Disadvantages Only a few components are upgradable RAM Hard drive Expensive to fix Prone to being dropped Might not have DVD player Might not have a numeric keypad
9
Nettop = MiniPC or MicroPC Advantages Low power consumption Very quiet Price ($200-400) (not including monitor) Great for email Basic interneting Disadvantages Limited processing power means it won’t do a lot of things at once
10
Tablets Generally operated by touch/finger gestures 5”-10” size Generally Android operating system Ipad runs Mac (iOS7) Windows tablet
11
Tablet Considerations Advantages Total portability— under a pound Very small—fit in any bag Loads of free apps Disadvantages Nearly impossible to upgrade hardware = disposable Surface subject to scratches Small amount of storage There are a lot of poor quality, cheap tablets out there
12
CPU CPU – Central Processing Unit AMD vs Intel Number of Processors/Cores Parallel processing Intel i5 has 4 cores 3.6GHz ($180-$220) AMD Phenom has 6 cores, 4.1GHz ($139) Intel Xeon, 6 core, 2.6GHz ($649) (specialized for servers) Intel Xeon has 12 cores (not released yet) Measured in Hertz – speed Now measuring in GHz (Gigahertz) Many sites will show benchmarks, which measures performance. http://www.tomshardware.com/t/cpus/
13
RAM – Random Access Memory Largely dictates how fast programs will load & how many programs can be running at the same time before things become very slow. Measured in Gigabytes (GB) - Capacity Also measured in speed (MHz) 2x4GB DDR3 1600 ($85)
14
Storage Hard drive Capacity Measured in Gigabytes (GB) 1TB is ~ 1000 GB 3TB Western Digital ($135)
15
Operating System & other Software Windows 7/8/8.1 Mac Linux (not very likely) No operating system Purchase system separately. Windows 7 is currently $139-$350 MS Office Full version currently $500
16
Finding a balance CostValue CPU (speed, type) RAM (speed, amount (GB)) Hard Drive (space, GB or TB) Software & OS Battery (Laptops/netbooks) Extended Warranty? Refurbished? Often include manufacturers warranty
