Microprocessor theory • Clock time (x mhz, x ghz) • Word size (x bit) • Cache (l1 in chip; l2 close; l3 less close) • Instruction set (categories:CISC, RISC; architectures: IA64,IA-32) • Hyper-threading • Many processors inside one processor • Many separate processors on one board • Manufacturer • See moodle’s useful sites – hardware for updates
Microprocessors on the market • Intel • i-3, i-5, i-7 • Intel Core2 Duo; Extreme; Quad • Pentium dual-core; Pentium 1- 4; • Pentium M: laptop • Celeron : budget • AMD • Athlon II X4 • Phenom; Turion; Opteron : current • Athlon X64 ; old premier • Duron, Sempron : old budget • Transmeta • Crusoe – tablet • Motorola • Power PC – MAC no longer used in mac since OS 10.7
Microprocessor high needs • 3-D animated computer games • Desktop publishing • Video editing • Upgrading later is usually not cost-effective
RAM • Random Access Memory • Lose it when computer off • Like your head’s short term memory • Main measurement is size (Gb, Mb) • More than cache, much less than hard drive • Speed (Mhz) • Has a type: RDRAM; SDRAM; DDRRAM • Expandable limits
ROM BIOS & CMOS • ROM BIOS • Read only memory to start up your system • No relation to CD-ROM • CMOS • Basic hardware path settings • Programmable • Very low battery needed • Neither usually effect your purchase
Motherboard • Traffic cop • Everything connects to it • Hard disk to RAM to CPU via bus • Motherboard chipset moves data faster • 800 MHZ bus last year to
Storage Introduction • CD, DVD, Hard Drive, Floppy, Zip, Tape, flash drive • Media – holds the data • Device - writes and reads the data • Need drive bays • Need expansion slots • Measures • Versatility of drive • Durability • Speed • Capacity
Hard disk - Magnetic • Notebook – Space • Controller • Serial ATA • Ultra ATA – 2 x EIDE (UDMA data transfer) • EIDE - old • SCSI – fast, but expensive • Memory • Sudden Death – backup • Speed (RPM) vs Access Time (MS) • GOOD MOVIE or Hard Disk to RAM
CD / DVD - Optical • Access speed – 2x, 24x or kb/sec • CD-ROM (read only) – just read • CD-R(ecordable) – write once ;read by all • CD-RW (read /write) – write a lot; read by few • Same for DVD, but it has +/- formats • DVD-RAM : video editing • Blu-Ray (Sony, Samsung, Sharp, Thomson, Hitachi, Matsushita, Pioneer and Philips, Mistubishi and LG Electronics ; supported by Warner Bros.)* • HD-DVD (AOD) (Toshiba and NEC; supported by Paramount and Universal ) * * Blue Violet Rays insteadof Red LINK TO INFO ON HD-DVD
Pointing Devices • Track pad • Track ball • Mouse • Pointing stick (the red knob on a laptop)
Expansion Slots • ISA – old / modems • PCI –graphics, sound, video, modem, NIC • ACP – graphics • PCMCIA – laptop • Type I – memory • Type II – modem, sound, nic • Type III – hard drive or two of the other
Expansion Ports • Device plug • Often on expansion card (in expansion slot) • Types • Serial – mouse or modem • Parallel – printer; external drive • USB – lots • SCSI – disk drive; cd rom; scanner; tape backup • IEEE (firewire) – video camera; DVD player • VGA - monitor
Monitors • Graphics card to give a boost • CRT (large, all angles, smaller screen, cheaper) / LCD (small, full screen) / Plasma (expensive) • Resolution – dp (dot pitch –smaller is better) • Viewable image size • Color depth or bit depth (true color is 24) • Graphics card
Terminology • www.webopedia.com • www.hyperdictionary.com • Many others
