Response to “Kitchenette Building” The poem “Kitchenette Building‚” by Gwendolyn Brooks‚ is a rather depressing outlook on those in poverty. The poem reveals how truly horrid the circumstances of the poor are. In the first stanza she says‚ “’Dream’ makes a giddy sound‚ not strong like ‘rent‚’ ‘feeding a wife‚’ ‘satisfying a man.’” By this she means that‚ while the word dream is an enjoyable thing to think about‚ there are too many other things that the poor have to think about‚ like paying the rent

There is nothing more important in any business than securing your network topology from hardware‚ design and software. This plan is called network hardening and this plan needs to be incredibly detailed with how the network will be secured in each area. The first step to the network hardening plan resides in how you will build the network and then from there how you will secure each section of the network. This paper will discuss access control measures‚ encryption‚ PKI‚ certificates‚ OS hardening

Introduction Network architecture is a combination of topology and protocols. In this paper‚ I will discuss topology‚ which is the defined as the shape of a network or how a network is laid out. Topology also consists of how the different components or nodes of a network are connected and how they communicate with each other. Topologies are either logical or physical. In addition‚ in the sections of this paper‚ I will compare and contrast some different conventional architecture and what types of

Carrier Sense Multiple Access with Collision Avoidance. However‚ simple CSMA is susceptible to the hidden node problem‚ especially in so called ad hoc networks where a node may communicate directly with every other node in range or using intermediate nodes as relays otherwise. Hidden nodes cause costly packet collisions and thus significantly affect network performance. In order to combat the hidden node problem‚ a mechanism known as Request to Send/Clear to Send (RTS/CTS) handshake is often used. RTS/CTS
