1. 1.05: CPUs
There are two major manufacturers of CPUs today which are Intel and AMD. The system bus, carries information into and out of the CPU. The processor is usually measured in GHz and Dual Core processors have incorporated two processors into one CPU. The most common sockets among AMD and Intel processors are the LGA 775 and 754 and ZIF locks hold the CPU into socket. Fans that are placed around or on the CPU are used to draw heat away from it and out of the case. * System bus carries info into and out of the CPU; controls the functioning speed of the computer * Frontside (uses 64 bit) bus is when the system bus enters the CPU * Controllers manage communications between motherboard, basic functions and other components * ALU – Arithmetic Logic Unit * ALU performs multiple calculations. These gave earlier Pentiums their multiprocessing capabilities * Internal bus is used to provide communication between the ALU and the Controller and uses a 32-bit wide data path * Backside is used to provide communication between the ALU and the Cache * Multiprocessors are two CPUs on one motherboard * Cache uses SRAM(static RAM) and is much faster and holds memory without being refreshed unlike DRAM(dynamic RAM) which must be refreshed * 3 types of cache: * L1 is on the processor chip * L2 is inside the processor housing, not on chip * L3 also in processor housing, further away from chip * Optimal temperature is around 90-110 F
Almost all the information from this video I understood and noticed some things that I had no knowledge about and can be found by one looking at the motherboard. The buses are used to connect all these components to one another on the board. I also learned the difference between specific older and newer Multiprocessors and Dual Core processors as well as the components required for these to be considered what type it is. The Cache though it explained the difference between the two quite well but I felt a bit lost with some stuff. When I finally get the change and have the time to build my own personal computer, this information will help tons because as much as I use computers there are things I still need to learn and am learning.…...

...Unit 5 Assignment 3 Cardiovascular The cardiovascular system, also known as the circulatory system, is a system of the body comprised of the heart, the blood, and the blood vessels. This system is responsible for transporting blood. As the cardiovascular system moves blood throughout the body, cells receive oxygen and nutrients. Carbon dioxide and other wastes are removed from the body as well. Carotid artery  The function of this carotid artery is that it carries blood away from the heart. The arteries are made up from blood vessels and these supply blood to the head neck and brain. The artery is on each side of the neck, left and right. Each carotid artery branches into internal and external vessels near the top of the thyroid. The only important function that the carotid artery has is to carry the blood to the head, neck and brain to supply it with blood. The right hand side and left side carotid arteries both link off. The right side is known as the internal carotid artery which supplies blood to the brain and the eyes. The left side of the carotid artery supplies blood to the throat, neck glands, tongue, face, mouth, ear and scalp. They both have different jobs where they have to supply blood too, both these jobs are important to supply the top half of our body with blood. Subclavian arteries  the Subclavian arteries carry blood away from the heart. Subclavian arteries are both on the right and left side of the body. The right Subclavian artery extends......

...CPUs There are two major manufacturers in today’s market – Intel and AMD. How a CPU will vary from CPU to CPU The motherboard system bus carries information into and out of the CPU When the system bus enters the CPU it is commonly called the front side bus and usually uses a 64-bit data path. Inside the CPU you have controllers that manage the basic functions of the CPU and control communication between the between the motherboard and other components within the CPU. These other components include one or more ALUs and the internal cache. An ALU (arithmetic Logic Unit) is responsible for performing complex calculations. Having multiple ALUs inside a single processor is what gave the early Pentiums their multiprocessing capabilities. Communication between the controller and the ALUs uses a 32-bit wide internal data bus. The bus system that supports communication between the cache system, the ALUs and controller is referred to as the backside bus. CPU Speed The most important thing you need to know about a processor is the speed at which it processes information. Unfortunately, there are several ways of measuring speed and they are frequently misleading. First, you should understand that speeds differ inside the processor and outside the processor. Internally, the processor may work up to 3.2GHz, but the system bus may only run at 800 MHz. Consequently, when you buy a new computer the CPU may be rated at 3.2GHz, but the question you really need to ask is what is the...

You should not buy either until you have made a decision about both and the case you need is also determined by these decisions. There are three form factors to determine these. * Atx form factor- has soft power switch and many slots to support different connections and uses a p1 power connector * Replaced older at form factor * Smaller * Better organization * Easier to work on * Wide support for I/o devices * Wake on lan feature * Btx form factor- supports a p1 power connector * Better air flow for cooling with an intake vent in the front and an exhaust in the back * Cpu heatsink fins and memory modules installed parallel to airflow * Nlx form factor- supports riser cards and usually installed on lower end computers * Fit into expansion slots * Provide connectors for additional expansion cards * Also known as daughter boards Bottom of the mother board holds the bus system which lets the board communicate with the different things installed on it, these are called communication buses.

Summary: The video taught me that everything that was developed after series 9x of operating systems is built on the NT platform. Also the NT did not have a device manager or a hardware wizard as well as not supporting plug and play. I also learned that Linux was developed by a Finnish student named Linus Torvalds.

...Unit 7 Assignment 1: Video Summary 5 BIOS is the first program activated during boot. This instruction set is permanent. Power-on self test checks basic system hardware, checks memory, and assigns system resources. The startup BIOS also checks CMOS settings. This is not permanent because it comes from RAM so it may be changed. BIOS and CMOS are different. BIOS is stored in ROM and permanent. CMOS is stored in RAM and volatile. CMOS settings are not lost during power outage because the CMOS battery provide power while shutdown. A common system of low battery is a slow clock. The system will still reboot if you clear the checksum error. The bootstrap loader runs POST, which checks CMOS, which reads MBR, which finds active partition, which loads the 1st OS file. To make changes to the BIOS by changing the Motherboard or flash the BIOS. BIOS is Firmware not hardware, or software. EEPROM stands for Electronically erasable programmable ROM. New BIOS lets you download a copy of new BIOS firmware from the manufacturer’s website. You can run BIOS flash installer. There are four system resources IRQ, I/O addresses, Memory Addresses, and DMA. IRQ is the interrupt request. It’s the communication channel from the hardware device to the CPU. IO address stands for Input/Output address and it’s the Hardware devices assigned address. The CPU sends instructions to address and the Device listens for address. The IO address is similar to device name. CPU communicates with the hard drive by......

There are some minor competitions but don’t stay on the market for long. The system bus for the CPU is also known as the Front-side bus as it inserts the CPU and has a 64 bit data pass. In the CPU theirs a controller that controls communication between the motherboard and other components with the CPU. The ALU is responsible for performing complex calculations. Communications between the controllers and the ALU’s uses a 32 bit wide internal data bus. A processor is usually measured in GHz. A system Bus is usually measured in MHz and has limiting factors of speed. The multiplier is the ratio between processor and the System bus. The system bus speed x multiplier equals the processor speed. CPU manufactures have come up with different ways to make the CPU work faster. Two multi-processing requires multiple processors (In other words your system must be designed to support more than one CPU on a single motherboard). Dual Core Processors have been recently developed, that means incorporating multiple processors with multiple ALU’s inside a CPU. These ALU’s process their information individually. There’s two cache memory’s which are SRAM and DRAM. SRAM is also called Static RAM, it is faster and more expensive then DRAM, it holds memory without being refreshed and DRAM must be refreshed. There are three types of RAM which are L1 cache, L2 cache, and L3......

Unit 6 Video Summary

...The video briefly discussed storage devices for computers. It covered internal storage devices, such as hard disk drives, and external storage, such as 8 ½ floppy disk drives. The video also described the different type of hard disk drive connectors which are as follows: * SATA * PATA * SCSI The video also had a rather detailed breakdown of how an internal hard disk drive works. During the explanation of how the drive works he used several terms that most people might not understand right away which he then defined for clarity. Following is a list of just a few of the terms that were used: * Platter – Disk located in the hard disk drive that data is stored on. * Track – a virtual ring on the platter used as a “groove” that data is written on for access purposes, similar to the grooves on a record. * Cylinder – vertical location of the platters within the hard disk drive. Combinations of platter number in the cylinder as well as track information are needed to retrieve data. * Latency – the delay before a transfer of data begins following an instruction for its transfer. Personally, I believe that the video was rather brief on a lot of the storage devices that were covered. The internals of the hard disk drive were covered very well; however, more time could have been put into describing the other forms of storage as well. Overall it was a very informative video, and I would recommend it to others needing to know more about storage devices....
