Cisco A+ questions?

Please help me with some questions i tried looking thru my study guide but couldn't find the current benefitial answer. (If you dont know all of them answer what you can please) thanks alot 1. The design department recently doubled the RAM capacity in all of the laptops. After the upgrade the laptop users reported the experiencing improved performance. Which operational benefit have the users noticed after the RAM increases (Choose 1) CPU reduces the number of operations by cycle. BIOS can use more RAM for I/O buffer space CPU Is now able to implement throttling Hard disk swap file is read less frequently hard disk partitions are automatically extended 2. Which portable connection provides the user with the possibility of high-speed Internt connectivity? (Choose 1) Cable Cellular Dial-Up DSL Mobile LAN

  1. 1) Hard disk swap file is read less frequently - your RAM is a lot faster than your hard disk. And with a lot of RAM, you'll have more recently accessed data available in a fast medium. You have more data "hits" is another way to put it. Otherwise your computer would have to constantly swap data in the Hard disk's swap file to the memory and vise versa (a very costly process). 2) DSL - yes, DSL is portable. In the sense that you can carry it around now and the fact that you can use it in most systems no matter what architecture they use. If that doesn't convince you then just note that cable is definitely not portable, cellular is slow as hell (slower than dial-up), dial-up (uhhh), and Moblile LANs don't guarantee internet connectivity (note the words "Local" Area Network).
  2. Answer1 = Hard disk swap file is read less frequently. This is referring to virtual memory, where an amount of the hard drive is allocated to the CPU for memory usage. Also why people with full hard drives experience massive slow-downs. Answer2 = Cellular. Cell technology is starting to be called wireless DSL, exceeding the 1Mb range.
