...Katherine Lund Unit 5 Assignment PA350 Social Security and Disability Law April 1, 2014 Step 1: Work Test-Is the claimant working and earning more than substantial gainful activity? Johnny Superton is working for his brother’s lawn mower shop and getting paid $320.00 per week which equals $1,376.00 per month. This is over the $1070.00 amount that Social Security has set in place for substantial gainful activity. Therefore, he would be denied benefits in step 1 of the SSA’s five step Sequential Evaluation Process for Determining Disability. Step 2: Severity Test- Does the claimant have a severe impairment that significantly limits his or her ability to do basic work activities and that also meets the duration requirements? Johnny Superton does have a severe impairment that significantly limits his ability to do basic work activities. Because of his accident, the doctors had to amputate his right leg just below the knee due to an uncontrollable MRSA infection, amputate his left foot due to gangrene. Although he has prosthetics, he is unable to use them because they do not fit well. The injury occurred on March 1, 2013 which also means he is within the duration requirements. Step 3: Medical Listing Test-Does the condition meet the SSA’s medical listings, or is the condition equal in severity to one found on the medical listings? Section 1.04 of the Disability Evaluation Under Social Security is disorders of the spine. In his accident Johnny’s L5-S1 disc burst and...

...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...

Unit 5 Assignment 1 Cabling Factors and Tolls Discussion

...Unit 5 Assignment 1 Cabling Factors and Tolls Discussion Flexibility What type of install is the cable going into? Is everything in a fixed position? If you have an install where items are moved around without being disconnected, using highly flexible cable is necessary. Cables in these scenarios need to be flexible to meet those demands of mobility, and also for the life of the wire so that it does not crack, break, fray or short. We had a job at a university where we moved flat panels on a track system to create different screen sizes, and for that we had to make sure the cable would meet the demand. Capacitance Cat 6 is not always better than Cat 5. If a video extender is made for Cat 5e, using Cat 6 may cause you a problem. The electrical properties are different, and the circuitry inside may not be able to reconcile the increased capacitance. You should confirm with the manufacturer before making a substitute in a Category cable. Jacket What type of jacket does your cable need? You have plenum, riser, PVC/non-plenum and direct burial. Plenum cable is often required in commercial work, especially in buildings where there are open-air returns; it is essential to meeting code. Integrators will often use riser grade at the riser, and then transfer to plenum in the plenum space. This saves some cost, but I recommend you second-guess saving that few cents per foot in most cases. The chances of mixing up a box of cable and pulling riser in the plenum space may increase...

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.

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...

...Data Protection Act 1998 The Data Protection Act 1998 covers data in electronic formats and also applies to manual data. This Act ensures that individual’s personal data is kept confidential and only should be broken or approved to see is the individual’s life is at risk. In order to follow this Act the service provider should keep client’s information confidential while safeguarding and protecting them. One example is that a carer isn’t permitted to share their client’s information or detail with family or friend. This is because to protect service user (elderly resident) from harm and danger. However, if they do they will be faced with serious consequences and even get a fine or sacked. This can also lead to establishment being closed down. There are eight principles that are covered by the Data Protection Act. One of those principle clearly state that a client’s personal information should be kept private and confidential and only be broken for any law purposes.
