Unformatted text preview: Motherboard Main System Board, other components connect or are part of the motherboard (main board, system board, logic board) Heart of the computer Other components connect to the motherboard Video on IBM and Microsoft: http:// www.youtube.com/watch?v =R8xIdkw6Zvk Chip = a small piece of semi conducting material that integrated circuits are etched. An integrated circuit is a pathway capable of carrying electrical current and contains millions of transistors or gates that open or close the circuit for the signal  One of the most important ones is the CPU (Central Processing Unit)  Speed (called the clock speed is measure in GHz (gigahertz) for current machines P r o c e s s o r , C a c h e , P r o c e s s o r s p e e d a n d F S B ( f r o n t s id e b u s ) s p e e d Intel (85% of the market) Core Duo, Pentium, Xeon, Itantium, Celeron, Centrino Duo)  AMD (Advanced Micro Devices) 50% of market it outside US Athlon,Opteron, Turion, Sempron, Radeon)  Server Processors, Desktop Processors, Mobile Processors  Processor: Type of processor, speed, amount of cache Intel Core2 Duo Processor (2MB L2 Cache,3.16 GHz,800 MHz FSB) Clock speed  Components: ALU (Arithmetic Logic Unit) and the Control Unit, storage locations called registers  Pace of machine cycle controlled system clock Machine Cycle: what the CPU does each time it performs an instruction  Measured in GHz (modern PC)  Hertz = how many times something happens per second  How do I know the speed of my processor? Right click on the My Computer Icon, select properties and select the General Tab  What is CPU usage  Press: [control][alt][delete]  Select Task Manager, Select Performance High Speed memory used by the processor  Located directly on or next to the processor Level 1 thru Level 3 cache More cache memory = better CPU performance When buying a computer, all other things being equal, buy the computer with the most cache memory Typical sizes on a PC L1: 32 KB OR 64 KB L2: 512 KB TO 4 MB L3: up to 8 MB Formulated by Gordon Moore, Co-founder of Intel. A prediction about the pace of improvement for CPUs (CPUs will get faster). The number of transistors helps determine how fast the CPU can process data. That the number of transistors would double every 18-24 months. There are over a billion transistors on the Intel Dual Core Itanium processor. Motherboard - The motherboard is the main circuit board of a microcomputer. It is also known as the mainboard or system board.  CPU - The CPU is the central electronic chip that determines the processing power of the...
