A port expander is a hardware device that will allow users to utilize multiple devices on a single port at the same time. It is the same principle as using a power strip for the power in a home or a splitter for the cable. For example, if you only have 1 Universal Serial Bus (USB) port, yet you have a USB mouse and keyboard, then you can use a USB port expander to allow one port slot to become multiple ports and plug in the mouse and keyboard. Allowing multiple devices to be able to connect to a single port is a major advantage to port expanders. However, one of the biggest drawbacks is that the speed of that port is now divided throughout all the expansion ports, an example being a 3Gbps port expanded to accommodate 4 ports will now have to split that 3Gbps between all 4 ports and not 3Gbps per expansion slot. There are two types of port expanders: internal and external. An internal port expander will usually connect to the motherboard and have an expansion plate with multiple ports along the box of the computer. An external port expander will plug into an existing port (such as a USB) and will then have multiple connections off of the port expander. Port expanders are also very generic and will allow expansion on just about any computer. There are many ports available that come with port expansion hardware. Some examples are, but are not limited to, USB Port Expander Hardware, Microphone Port Expander Hardware, FireWire Port Expander Hardware, Serial Port Expander Hardware, SCSI Port Expander Hardware, Audio Port Expander Hardware, RS-422 Port Expander Hardware, SATA Port Expander Hardware, Ethernet Port Expander Hardware, Modbus Serial Port Hardware, SSD Port Expander Hardware, SAS Port Expander Hardware, DB-25 Port Expander Hardware, VGA Port Expander Hardware, Video Port Expander Hardware, and DVI Port Expander Hardware.

Unit 5 Assignment 1: Video Summary 3 Cpus Nt1110

...Fredrick Donaldson Nov.5, 2014 NT1110 Unit 5 Assignment 1 Video Summary 3 CPUs In today’s market there are 2 main manufacturers of CPUs: Intel and AMD. There are also some smaller competitors that manufacture CPUs, but they tend to come and go. The way a CPU is organized varies, but here are the basics: The motherboard system bus carries information into and out of the CPU. When the system bus enters the CPU, it’s called a Front side bus. The Front side bus usually uses a 64-bit wide data path. On the side of the CPU you will find a controller. A controller manages the basic functions of the CPU, and controls communication between the motherboard and other components within the CPU. These other components includes one or more ALUs and internal cache. An ALU (Arithmetic Logic Unit), is responsible for solving complex calculations. Having multiple ALUs in a single processor is what gave the early Pentiums their multi-processing capabilities. Communication between the controllers and the ALU uses a 32-bit wide internal data bus. The bus system that supports communication between the cache, the ALU, and the controllers is referred to as the backside bus. The most important thing a person needs to know about a processor is the speed at which it processes information; (CPU speed). There are several ways to gauge CPU speeds. This may sound like an advantage, but oftentimes, these multiple ways are misleading. The speeds differ inside and outside the processor. Internally...

Having a faulty fan. Another reason would be not enough air flow coming and coming into your computer. 2 Overclocking is to run a microprocessor faster than the speed for which it has been tested and approved. 3 Throttling process is a process responsible for regulating the rate at which application process scene is conducted either static we are dynamically 4 Thermal compound increases the thermal connectivity of a thermal interface five billion microscopic air gaps in imperfect flat smooth surfaces 5 Since the core or processor is a unit that reads and executes programs instructions, such as copy or move data. multiple cores can do multiple instructions at the same time increasing overall speed of the programs itself 6 Hyper threading is used to improve parallelization of computations or doing multiple tasks at once performed on the PCs microprocessor. It addresses two virtual or logic corps and shares the workload between them when possible the main function of hyper threading is to decrease the number of depending instructions to one core. 7 A cache is used to reduce the average time to access memory cache is a smaller faster memory which stores copies of the data from frequently used memory locations.

...Unit 5 Assignment 1: Video Summary NT1110 There are two major manufactures we use in today’s market which are Intel and AMD. 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 cache...
