Information Systems vs Information Technology What is an Information System What is Information Technology Are they different or the same Information Systems Technical System Most often the hardware software and other technology used to create exchange and use information Can also be a specific process or technical way of doing something ie division of labor Social System Organizational culture norms informal communication as Knowledge System Includes company information which can come from people organizational processes or more Employee s experience and wisdom Information Systems Security Technical System Computers routers antivirus software firewalls etc Formal System Rules security policies regulations ie must have a strong password Informal System Security culture norms ethics etc

Chipset o A set of integrated circuits that orchestrate data to and from components such as the CPU RAM PCI slots hard drive etc Controls communications between the processor and other components o North Bridge links the CPU to high speed devices like RAM and Graphics eg PCI Express amp AGP Also links to the south bridge o South Bridge links slower devices like USB audio and Ethernet and BIOS Buses 0 Front Side Bus Carries data between the CPU and North Bridge On newer processors with some north bridge components built into the CPU it carries data between the CPU and those components 0 Back Side Bus Carries data between the CPU and cache There is no back side bus on newer processors that have all cache built in o PCI Bus carries data to the PCI slots 0 LPC Bus ow pin count bus used for low bandwidth devices like BIOS od keyboards and mice Cache 0 L1 Cache typically resides in the CPU o L2 Cache typically resides on the motherboard 0 L3 Cache typically resides on the motherboard and many times is not present o L2 and L3 cache is connected to the processor through the back side bus but some newer procrassors have all cache built into the processor therefore eliminating the need for a back side bus because the cache is no longer on the motherboard 0 Cache anticipates CPU requests by having frequently accessed instructions preloaded such as launching the web browser 0 Why not have on big cache Because the larger the cache the slowerthe search L1 cache is typically smaller and faster and contains the most frequently accessed instructions 0 L2 cache is typically a little bigger and a little slower to search and contains the second most accessed instructions L3 cache is typically bigger and slower than L1 and L2 cache and has the next most frequently accessed instructions All of these caches are faster than SDRAM Cache 0 Once a request is made eg launch Excel 0 O O 0 L1 cache is searched for the instructions L2 cache is searched for the instructions L3 cache is searched for the instructions RAM is searched for the instructions slower than cache And finally the hard drive is searched much slower than cache and SDRAM Some hard drives have caches as well hybrid solid state hard drives making them faster Finding the instructions in cache is called a cache hit otherwise it is a cache miss into pieces whichever processing do more things simultanercu

that enables communication between a hardware component in a computer and the operating system 0 For example a ngerprint scanner on your laptop will need a driver to tell the operating system how to communicate with the device Without the driver the ngerprint scanner will not operate 0 Almost everything needs a driver Examples are chipsets modems network cards video cards monitors USB ports DVD drives hard drives processor laptop batteries etc 0 Windows operating systems come with built in drivers for many devices and it recognizes them during the operating system installation process 0 Sometimes even though Windows has a driver for a device a better suited driver may be available from the device s manufacturer 0 Devices that Windows fails to recognize need to have drivers installed

possible do not use the drivers that come on the CDDVD with a newly purchased device or part 0 Instead download the latest driver from the manufacturer s Web site Many times there are updated drivers on the Web site The CDDVD could have been made several months ago which is plenty of time for there to be updates online 0 Sometimes Windows recognizes devices and installs a Microsoft created driver but the device is not performing properly Go to the device driver properties to see who supplied the driver and notice driver dates and version Then look for a driver from the devices manufacturer s Web site If you find one install it If not check with Microsoft for a newer version of the driver You can roll back if things get worse 3 0 Download the latest drivers for Windows 7 for your motherboard and video card if separate You do not need the drivers for the DVD or hard drive in most cases Rename the drivers to describe the device and save them on your ash drive Have them ready for installation if needed when we install Windows 7 o If a Windows 7 version of the driver is not available download the Windows Vista version If 7 and Vista are unavailable download the XP version There is a good chance the XP version will not work but it s worth a try 0 Go to your motherboard s manufacturer s Web site and search for drivers for your speci c motherboard 0 Do the same for your video card if you have a separate card
