Running head: information technology Information Technology Affiliation July 28, 2009 Question a- In this scenario of firm the employees need to do a lot of graphic design work. So they need a system that can support the high capacity Graphical Software. For this reason we will choose a system that can process high amount of graphical data and provide effective results. The rendering process in any graphic designing process needs large amount of processing power and memory space. So here the selections for the system configurations for the concerning firm are:
Hard disk- 200 GB
Thumb drive (USB 2.0)- 256 MB
Speed (clock rate)- 5 GHz
Here I have chosen a printer that can print 1200 dots per inch so this provides very sharp results and also the selection of the laser printer will ensure better results. The speed is not a great concern so I have chosen a medium speed for printing
Printer Laser
1200 DPI
Printing speed- 16 PPM
b. In this scenario we have a firm that uses computer only for word processing. The biggest application occupies 24 MB, so we do not require a system with huge capacity drives and processing power. The hardware configuration selected for this firm is given:
RAM- 512 MB
Hard disk- 60 GB
Thumb drive (USB 2.0) 256 MB
Speed (clock rate) 1.7 GHz
Printer Ink-jet Laser
600 DPI
Printing speed 12 PPM
c. In this type of firm we need systems that have extreme processing power and clock speed power. Here we have to process at high speed because scientific applications require more processing power, so configuration of the system is given below;
Hard disk 200 GB
Thumb drive (USB 2.0)- 512 MB
Speed (clock rate) 5 GHz
Printer Ink-jet
600 DPI
Printing Speed - 16 PPM
d. In this scenario we need a better printing power and this can only be achieved through enhanced memory. Because the printing current pages are stored in the RAM so we need better RAM as compared to processing power. Here we need a printer that can print the pages at higher speed. We also need big data travel drive.
Hard disk- 60 GB
Thumb drive- 512 MB
Speed (clock rate) 1.7 GHz
Printer Laser
600 DPI
20 PPM
Question 2
a. Magnetic tapes: In this scenario we need to store thousands of employee records for several years. This storage is only for backup procedure. Here we do not require processing of records. So we will choose the magnetic tapes those provide large storage capacity at less expenses.
b. Magnetic hard disks: Air line reservation requires fast and large record processing. Here in this scenario we require systems that provide high storage and fast processing speed. The selection of magnetic hard disks is the best choice for such areas of working.
c. Recordable optical discs (CD-R: write once, read many): the maintenance manual facility is effectively provided through CR-Rom technology. Main reasons of this technology selection are the less cost and appropriate capacity of medium for the maintenance manual storage.
d. Flash memory USB drives: when we want to take any digital data from one place to another then the flash memory USB drives are the best choice. These are high speed data travel mediums for both storage and retrieval. This flash memory USB drive will be better for this scenario of travelling data.
e. Magnetic hard disks: This scenario involves the huge data storage and faster access for the textual and graphical information from the site. Here customers also need to search products and make purchases from the online web site. Here we will use multiple magnetic hard disks for the storage and faster processing of the web data.
f. Recordable optical discs (CD-R: write once, read many): This situation involves the keeping of multiple copies and making them available for the loaning form the library purposes. For this situation CDs are the best medium: these are less costly and medium capacity data storage for the library tasks.
g. Magnetic hard disks: this medium is best for the database storage. This storage medium can be accessed and manipulated frequently.
h. Recordable optical discs (CD-R: write once, read many): here for the string millions of taxpayers record for several years and providing direct access to specific record we can use the CDs. CDs are recorded and named for the specific period of time. On any need we can pick the CD of concerning time period and access the data. Here can also use magnetic taps but the record retrieval is really difficult in this medium.
