Because of this it’s becoming the standard type of ROM used in motherboards

Flash Memory is a type of constantly-powered non-volatile memory that can be erased and reprogrammed in units of memory called blocks
RAM (Random Access Memory) It allows the computer to read data quickly and efficiently to be able to run applications efficiently
DRAM (Dynamic RAM) It needs to be refreshed thousands of times per second which makes it slow
SRAM (Static RAM) does not need to be refreshed, which is what makes it faster than DRAM.
SDRAM (Synchronous RAM) is an old and slow type of Random Access Memory. It used to ship with old Pentium systems and is starting to die out

DDR SDRAM (Double data rate synchronous RAM) It’s just like SDRAM except that is has higher bandwidth, meaning greater speed.
DDR2-SDRAM (Double Data Rate Revision 2 Synchronous Dynamic RAM) it’s similar to original DDR memory, but it comes with an external data bus in the memory modules. This doubles the memory’s the clock rate, but at twice the latency. Therefore, DDR2 will operate at twice the speed of DDR …show more content…
It is faster than DDR2 and supports 8GB modules, whereas DDR2 memory only supports 4GB per module
VRAM (VideoRAM) is also known as multiport dynamic (MPDRAM), is a type of RAM used specifically for video adapters or 3-D accelerators. The "multiport" part comes from the fact that VRAM normally has two independent access ports instead of one, allowing the CPU and graphics processor to access the RAM simultaneously

SGRAM (synchronous graphics RAM) Many people are using this instead of VRAM because performance is nearly the same, only the SGRAM is cheaper.

RRAM (Resistive RAM) is a form of non-volatile storage that operates by changing the resistance of a specially formulated solid dielectric material. A RRAM device contains a component called a memristor (contraction of "memory resistor"), whose resistance varies when different voltages are imposed across

...Unit 7. Lab 1. New Building – Safety Plan NT1310 Vincent Mckey March 1, 2014 New Building Safety Plan ​No matter what type of job being done rather it’s building a house or cutting grass. A safety plan should be in place. However safety plans differ pertaining to the job. Example, a person performing a routine task such as washing a car wouldn’t face the same dangers as someone who has the job of an offshore welder. When installing cable in a new building, there is some necessary safety equipment and safety equipment I would implement. ​Some of the safety equipment would be boots or rubber sole shoes, long pants, gloves, and eyewear. Although installing cable in a new building is not as dangerous as building the building itself, some of the same safety equipment or PPE should be worn. Also, there should be rules in place to keep the employees safe. These are ten rules I would implement: 1. No horse playing 2. No running on site 3. Do not climb ladders without having someone on the ground holding it 4. Do not leave tools plugged into electrical sockets unattended 5. Only spill proof bottles in the work area 6. The use of alcohol and drugs are prohibited 7. No fighting 8. No sleeping 9. Clean spills immediately according to the MSDS 10. Always wear PPE In case of a disaster, follow the buildings exit plan. Do not run. Walk swiftly toward the exit keeping your head on a swivel. A designated meeting place will be designed and all team members...

...NT1310 Codi Roebuck Unit 10 Lab 1 01/04/2016 Professor: Ronald j. wojcik Fiber optics for diagnostics and troubleshooting are used in varying capacities to test, measure, analyze, transmit, distribute, and/or simulate an optical signal with which the technician can perform procedures and processes associated with maintenance, problem solving, and calibration of equipment and/or networks. Normally in these applications, fiber optic products are used to create loop tests or transmit signals from point-to-point (either single-point to single-point, or single-point to multiple-points). For loop testing, commonly referred to as loopback testing, a signal is sent from a piece of equipment through a loopback or cable and returned to the source, simulating a complete network connection. This type of test allows technicians to perform function tests and internal diagnostic processes without the equipment being physically tied to an active network. This type of setup provides technicians with the advantage of easily isolating individual components for faster, more comprehensive analysis. With signal transmission applications, technicians generally use cables (multiple types for different applications) to connect one or more pieces of...
