18 Next a bit of geek speak
19 19 Computer talk ALL computer communication is done by 1 s and 0 s
20 20 From a bit to a byte! Size Doesn t Matter? Says Who!! Bit A Bit is a value of either a 0 or 1. Byte A Byte is 8 bits. Kilobyte (KB) A Kilobyte is 1,024 (2 10 )bytes. Megabyte (MB) A Megabyte is 1,048,576 (2 20 )bytes or 1,024 Kilobytes 873 pages of plaintext (1,200 characters) 4 books (200 pages or 240,000 characters) b versus B Mb = Megabit MB = Megabyte
21 From a bit to a byte! Gigabyte (GB) A Gigabyte is 1,073,741,824 (2 30 ) bytes. 1,024 Megabytes, or 1,048,576 Kilobytes. 894,784 pages of plaintext (1,200 characters) 4,473 books (200 pages or 240,000 characters) 341 digital pictures (with 3MB average file size) 256 MP3 audio files (with 4MB average file size) Terabyte (TB) A Terabyte is 1,099,511,627,776 (2 40 ) bytes, 1,024 Gigabytes, or 1,048,576 Megabytes. 916,259,689 pages of plaintext (1,200 characters) 4,581,298 books (200 pages or 240,000 characters) 349,525 digital pictures (with 3MB average file size) 262,144 MP3 audio files (with 4MB average file size) 1, MB CD's GB DVD's 40 25GB Blu-ray discs
22 Internal Computer Parts
23 About Your PC How it s put together
24 CPU 2 major brands Intel The name brand A bit more stable, standard More expensive AMD Very close in quality and performance to Intel Less expensive High-end better for gaming
25 25 The CPU
26 26 The CPU The Brains?? Performs calculations Manages data movement Chart sample from:
27 CPU Consider. Overall CPU score A general benchmark indicating overall performance. The higher the better: GREAT to use when comparing computers. Clock Speed How fast the chip is. Referenced in terms of GHz (GigaHertz). 3 GHz=3 billion calculations per second Number of cores Each core is like having a separate CPU. Generally, the more the better. Think of these like the number of cylinders in a car engine.
28 Motherboard The main circuit board that connects all the pieces of the puzzle Comes in different sizes known as the form factor ATX, Mini ATX, Micro ATX, Made specifically for the brand and socket type of the CPU Intel or AMD CPU, socket 1, 2, 3, 4, 7, socket 370, etc. Mad specifically for a certain type and speed of memory (RAM
29 Hard Drive Used to store your Operating system, programs and data New types are Solid State (no moving parts) Contains magnetic disks and moving heads to read/write the data Failure rates increase with time. Consider replacing ever 3 to 4 years. New hard drives cost about $60+
30 Hard Drives It s all about Size and Speed Size Size is referenced by GigaBytes and Terabytes A Terabyte is 1,000 GigaBytes Speed Solid state hard drives have NO moving parts Traditional hard drives operate at either 5,400 rpms, 7,200 rpms or 10,000 rpms
31 Memory The primary memory used when operating your computer Come as small circuit boards referred to as chips Vary based upon speed, Latency and size
32 Power Supply Converts your 120 volt alternating house current to smaller direct current (DC) voltages 3.3 volt, 5 volt and 12 volt Powers the Motherboard and all other devices attached to the computer Cheap ones start at $25 and better quality ones at $50
33 Video (card) Offers improved video capabilities for the PC Price varies based upon speed, amount of memory, etc. Low end - $50 High end - $1,000
34 Multi-media Device Allows your PC to play CDs, DVDs and even Blu-rays Some are read only for playing discs Some are read/write for writing information to as well Cost $25 + for CD/DVD $60 + for Blu-Ray
35 Connecting Your PC ADDING PERIPHERALS
36 Input & Output Devices 36 Everything attached to the computer is either for Getting information in Taking information Out Both
37 PC Connectors
38 Laptop Connectors
39 Keyboards Come in all sorts of shapes & Sizes Standard Keyboard: Qwerty Lit / Unlit Straight, Curved, Ergo dynamic Wireless or wired Price Range: $15 - $300
40 Mouse Trac-ball Old School Laser Current Standard
41 Mouse & Keyboard Connectors USB The current standard PS/2 Old School Wireless
42 Monitors Old School CRT Current Standard LED, flat or curved.
43 Monitor Connectors VGA Old School basic video HDMI Best overall digital standard cable carries audio & video Display Port/Mini Display Port DVI Similar to HDMI but not as widely used Generally video only, similar to HDMI
44 Connecting it all together Your LAN (Local Area Network)
45 Basic PC Startup Makes sure basic components are connected POST Power-On Self Test Sets up communication with keyboard, mouse & Monitor BIOS Loaded Basic Input/Output System MBR Loaded Master Boot Record Sets up communications with audio, video, DVD player, card readers etc. Gets information on where the operating system is on the disc OS Loaded Operating system Drivers Loaded Audio, Video, etc. Loads the operating system Log-in Screen User Accounts Lets you log in
