Lab Review 1.3 1. It is important to know how many system words will fit in a primary device so you will know how big your storage device is. 2.Multiple bytes has more ones and zero as bytes with holds more information a single byte only has a series of 8 bit which has less data then a series of multiple sets of 8bit. 3. When converting a big number you cant just line up the digits, you need to make the number into bytes so that each one can easily convert into a unit of dex. Lab Review 1.4 1.

...The difference in the cost of RAM and ROM in today’s market as well as where is where it came from and where it is going is pretty amazing. It’s easy to find information on this subject as the demand for faster computers with huge memory seems to grow and profit from this demand. Ten years ago you would have spent over $2,000 to get just 1GB of RAM. As computer manufacturers recoup cost of R&D, the prices start to drop. Today it would cost around $20 to purchase the same 1GB of DDR3 providing considerable savings over a decade ago. The best deal for the money is 2GB of RAM which costs around $40 and is enough memory to run most applications. There are other types of memory available to all of us if you’re willing to pay the price of admission. For example, some of the more exotic types of RAM can still run hundreds, even thousands of dollars. For instance, I found Super Talent 1TB STT RAID DRIVE GS RAID0 for $4,815.00 on Memory Suppliers.com. They also offer iRam 2GB (2 x 1GB) DDR2 SDRAM PC2-5300 667MHz for $119.00. I find this is a very nice web site that is easy to navigate through and find and compare the memory you’re looking for. The following table is from Archive Builders web site. It shows the growth to cost difference for 32 years. This was determined by the increase of the density of disks by 60% a year with an average decrease in price of 37.5%. The 60% increase is based on the growth predictions for MR head technology by IBM, which had increased...

...Matt Bristow NT-1110 Unit 6 Research Paper NAS Devices NAS is an acronym for Network-Attached Storage. It is basically a file-level computer built for data storage connected to a computer network providing data access to any computer connected to that network. The speed for any particular NAS device varies from 1 gigabit all the way up to 10 gigabits depending on what upgrades a pc has such as an upgraded network cards. The capacity range for NAS devices also depend solely on the budget set forth. It can be a low range system with 500 gigabytes, all the way up to a wallet-busting 16 terabytes. The fault tolerances when set at RAID 10 are the most stable since more devices can fail while protecting against any potential data loss. The advantages of an NAS device are that since it is a dedicated file storage device, accessing said data is a lot faster than typical in-pc hard drives. Another advantage would be the amount of storage you're capable of having. It far outpaces pc's in storage capabilities because all it is built for is storage. For a family with a lot of pictures or videos, the advantages are that any computer connected to the NAS device can access them. It's a library for any media/documents/or anything else you can think of that can be accessed at any time by any pc connected to it. They might be pricey for a casual pc user but when dealing with multiple pc's connected to a single network, an NAS device would be the perfect option when space becomes an...

...Question 1 The evolution of computer hardware and software has allowed computer systems to become more accessible and user friendly. With computers only being used by programmers in the 1940’s anyone can now successfully operate a computer with very little experience. This evolution has also allowed for more advanced functions that can assist with day to day activities such as scheduling, personal networking, and mobile communications which current generations have become nearly dependent on. Question 2 Insurance adjusters can now operate more efficiently with mobile computers by being able to generate reports in the field versus having to take notes and doing this once they return to their office, losing time and productivity. They can also wirelessly transmit these reports while in the field from their mobile computers allowing claims to be processed faster improving customer satisfaction. General practitioner doctors can also benefit from mobile computers by only having to carry one device on a cloud network to easily access all patient files in one location. He or she can also use this same mobile computer to wirelessly transmit prescriptions, referrals, or other orders instantly and securely improving patient service and confidentiality. Question 3 1 Megabit is 1,000,000 bits and 1 Megabyte is also 1,000,000 bytes but they are actually not the same. There are 8 bits within 1 byte and making 1 Megabyte the same as 8 Megabits.

(one thousand) 10^3 (Kilometer, 1,000 meters) - mega, meaning 1,000,000. (one million) 10^6 (Megawatt, 1,000,000 watts) - giga, meaning 1,000,000,000 (one billion) 10^9 (Gigawatt, 1,000,000,000 watts) - tera, meaning 1,000,000,000,000 (one trillion) 10^12 The smallest amount of transfer is one bit. It holds the value of a 1, or a 0. (Binary coding). Eight of these 1's and zero's are called a byte. Why eight? The earliest computers could only send 8 bits at a time, it was only natural to start writing code in sets of 8 bits. This came to be called a byte. A bit is represented with a lowercase "b," whereas a byte is represented with an uppercase "b" (B). So Kb is kilobits, and KB is kilobytes. A kilobyte is eight times larger than a kilobit. A simple 1 or 0, times eight of these 1's and 0's put together is a byte. The string of code: 10010101 is exactly one byte. So a small gif image, about 4 KB has about 4000 lines of 8 1's and 0's. Since there are 8 per line, that's over (4000 x 8) 32,000 1's and 0's just for a single gif image. How many bytes are in a kilobyte (KB)? One...

...profit sharing 3. free flow of information Employee participation: It is the cornerstone of the semco culture which indicates the participation of every employee in major decisions. Participation gives people control of their work. The company admits that it operates on involvement and participation of its employees. Employees were encouraged to share their ideas and opinions. For example, the purchase of new site or any merger is done via vote of all employees. The main problem according to semler is autocracy. According to him we are still restricted by a system that doesn’t allow democracy in workplace. It’s very important to include our every employee in day today decisions that we take in the company. Profit sharing: The employees determine the profit share that they should get and also decide how to split it. It creates the feeling of ownership, says semler. Employees enjoy 25 % of company’s total profit. It directly affects their efficiency. The way of working is different by the employees when they have a sense of ownership. Profit sharing give them a reason to do things better. They work more sincerely and with more effort. In this way employees themselves can decide that what they will get at the end of the year. Free flow of information: Each piece of information is available to everybody. Nothing is kept as secret.
