As it is very much clear form its name that it is used for expansion of boards in PC. The expansion boards are used to expand address, data and control buses which are used throughout the motherboard. These are of two major types’ 8 bit expansion slots and 16 bit expansion slots.

ETHERNET CARD:
Ethernet card is a type of expansion card. It is a kind of network adapter that is used to connect computer for networking and also to use internet via high speed internet/networking cables.
COMMUNICATION OF CARDS:
Expansion cards communicates with the processor through system bus. The system bus not only provides necessary signals to all the chips, i.e. RAM, ROM and peripheral chips, on the motherboard, but also goes to the expansion slots for any plug in expansion card. So as the expansion card connects with the system bus it indirectly connects with the address pins, data pins and also the control signals to send and receive signals, address and data from the computer and other computers, in case of Ethernet card.

There is also ROM which is used to store BIOS data in it which will require at the startup of the computer.

...him was. I was able to reduce my phone bill by $200 a month just by asking the question, "What's the best deal you can give me? There are a lot of phone companies asking for my business so I want to know what you can do to convince me to stay with you." That's $2,400 back to the bottom line each year. Remember that I'm giving you ideas on how to boost profits. Reducing expenses increases the amount of money you have left over at the end of each month. Don't ignore this. Sure, you can sell more but in a down economy, it's a great strategy to focus on negotiating new terms that benefit you 100% so that when the economy gets strong again, you'll be making more money and spending less of it. Both working together results in fatter wallets! 3. Don't include a lot of extras in your video proposals. Having a lot of extras in the initial video proposal drives cost up which can drive customers away or leave room for your competition to bid lower than you. I recommend that you quote the shooting and editing part of a video and only include 1 copy of the DVD master. Then, in your video proposal, tell them that additional copies and/or website files can be provided for an additional fee. Most of the time, they will forget about the copies or the digital files until the project is complete.

Currently the lead time, after product launch, is eight months, working thirty hours on a five work week. Two hours a day will be dedicated to lunch and at least one-hour long meeting. A team of six production managers are scheduled to complete the launch. The takt time would not be affected since there will be a dedicated team to handle the production of the new program. Traditionally, takt time is calculated by dividing the net available time by the customer demands (Pereira, 2010). The only situation that would impact the takt time is the client becoming more demanding and additional resources needed to help the critical path. Bottleneck: Bottlenecking is a common situation that occurs in production situations. The following situations could adversely affect the cycle time of the new software program: - Inaccurate measurement of resources needed – programmers, space, time - Fluctuation in the key process parameters that would increase the demands of the customer - Unscheduled downtime – internet outages, storms affecting employees work habits, sick time - Slow turnaround between platform launches – delivery of products - Customer needs change - Human Factor and Error Lean Management Impacts: Microsoft has an efficiency pursuit in how their brands are re-engineering and how their business is conducted.

...There are four main categories of MV applications in the industry: inspection, guidance, gauging and identification. Inspection Inspection is the process of comparing the individual manufactured items against some pre-established standard with a view to maintenance of quality. The process of inspection commonly take places in three definable stages: image acquisition, object location and object scrutiny and measurement (Davies, 2012). The inspection category is the broadest in machine vision applications. Machine vision can be used to correct the location, control the quality and check the completeness. A typical machine vision application is to inspect the surface of an object. It is essential to identify the defects like scratches, printed strings on the surface of the objects. In the conclusion part of this paper, I would design an IC orientation inspection equipment with the machine vision system based on this application. First, a digital camera obtains the IC’s surface image. Second, the MV software does image processing to extract some useful and critical information. Third, the MV software compares the extracted information with the template image. Last, MV software outputs a signal to programmable logic controller (PLC) based on the comparing result. If the result is ok, the MV system will check the next IC. If the result is not good, the MV system will trigger an alarm system. The MV system will not perform the next procedure until the operator acknowledges the alarm...

At the end of the day they need to turn these observations into concise reports, a client proposal, or transfer the observation information to others. That's a big job, especially since each site is unique, and requires documenting the complexities of commercial roofing information, and the critical observation areas of the roofing system. In the past John would use his tablet computer to take pictures and make notes to transfer to a word document for his reports. Mike, took lots of photos with digital camera and updated his companies home grown web application. That was fine when buildings were simple. However, John was adding more and more complexity into his homegrown templates, and to be honest the information that made sense to him was not in any industry format. Mike, had other challenges trying keep reports consistent when their company roofing app was not able to support the variety of roofing systems and defects, so it was common, if the internet was down, or the data was not supported, Mike went back to pen and paper.

...support the customer’s business needs. Configuration does not make any changes to the core software code, but instead updates tables with settings and entries specific to the customer’s business. Called configuration tables, these tables enable a company to tailor a particular aspect of the system to the way it chooses to do business. Project team members can use configuration tools to select alternatives through an easy to use GUI. These selections then behave like switches that tell the software to perform differently based on the values selected. For example, configuration may allow the company to specify: • Whether accounting for inventory should be based on LIFO or FIFO. • Whether the company wants to recognize revenue by geographical unit, product line, or distribution channel (or all three) • How many legal entities are reflected in the system • What the default currency will be. SAP has over 3,000 configuration tables and there are approximately 8,000 configuration decisions to make when implementing it. Navigating through them can be a formidable task. For example, when Dell Computers implemented SAP, the configurations alone took over a year to decide upon. As ERP software vendors attempt to gain market share, they continue to provide configuration options to address and increasing number of system requirements, thereby broadening their target customer base. So what happens when the options the system allows don’t exactly fit business requirements? At this point...
