IT331 - Capstone ISA Final 3.0
Topic 1: Hardware
Learning Level 3:
You are building a LAN in a company that develops insurance management software. What hardware requirements should be taken into consideration?
The most important piece of hardware would be the network interface card (NIC). Connectivity devices such as hubs, repeaters, bridges, routers, switches, and gateways can be used to extend the LAN. Transmission media can include coaxial cable, twisted pair wiring, fiber cable, and radio waves.
1. For the desktop stations, you should consider Physical Ram for running the programs, Space on the hard drive for the software they would need to store, and processor strength for test running and for debugging.
2. For the Network you would consider routers for distribution of packets, bridges for physical connections of routers, switches for direct connections and the cabling for the connections and other sorts of informational distribution. Patch Panel connections.

Learning Level 2:
Describe how the memory manager divides up and allocates memory.
Some OS routines directly support application programs as they run and thus must be resident. Other transient routines are stored on disk and read into memory only when needed. Fixed-length partitions can also be used to allocate the set amount of memory that a particular program needs to run. Under dynamic memory management, the transient area is treated as a pool of unstructured free space. When the system decides to load a particular program, a region of memory just sufficient to hold the program is allocated from the pool. Using segmentation, programs are divided into independently addressed segments and stored in noncontiguous memory. Paging breaks a program into fixed-length pages.
1. a) The operating system occupies low memory, starting with memory address 0. Directly afterwards is system control information, then the various resident operating system
