About Your PC How it s put together

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 The CPU

26 The CPU The Brains?? Performs calculations Manages data movement Chart sample from: http://www.cpubenchmark.net

CPU Consider. Overall CPU score A general benchmark indicating overall performance. The higher the better: http://cpubenchmark.net. 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.

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

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+

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

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

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

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

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
