Network Design In this paper I will be going over a network design proposal for a building on the UMUC campus in Adelphi‚ Maryland. I would plan to run a fiber optic network to ensure the fastest speeds possible and fiber optics are notorious for not having any signal loss compared to a Cat5e. Using a star topology throughout the building with the servers in each classroom connected to the server room on the respective floor. Equipment used to build the network will consist of servers‚ routers‚ hubs

I have decided to pursue the career of a network system administrator or IT professional. Over the last ten years or so computers have become fundamental parts of everyday life‚ used for a variety of reasons at home‚ in the workplace‚ and at schools. Of course every computer user runs into obstacles from time to time‚ whether it is the blue screen of death‚ the forgotten password‚ or the loss of important data. The explosive use of computers has created a high demand for specialists to provide advice

This is extremely important for the flexibility needed to efficiently utilize network assignments for an ever-shrinking pool of IP addresses. 6 What is convergence and why is it important?

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

addiction is becoming one of the biggest non-drug addictions in the 21st century. Along with the age drop of the mobile phone users and the ease of prepaid method provide by the system operators‚ most teenagers now own their own mobile phone and network service. Teenagers are engaged on their mobile phones all the time‚ no matter on phone calls‚ using SMS text messages‚ personalising the mobile phones with ringtones and pictures etc. Besides this‚ many people are running after the lastest mobile

CHAPTER 4 HARDWARE DESCRIPTION 4.0 Arduino: The Arduino Uno is a microcontroller based on the ATmega328. It has 14 digital input/output pins in which 6 can be used as PWM‚ 6 analog inputs‚ a 16 MHz ceramic resonator‚ a USB port‚ a power jack‚ an ICSP header‚ and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.[11] The Uno differs from all preceding boards in

the security features currently employed by the company. Management outlined a comprehensive plan that included a complete hardware refresh‚ security best practices and end user training. Team “C” will devote resources to assess the physical and network security issues and concerns at each Riordan plant. Once those have been identified‚ Team “C” will identify the data security issues and concerns present at each Riordan plant. Finally‚ Team “C” will address web security issues and concerns present

Network security concepts Network security starts with authenticating‚ commonly with a username and a password. Since this requires just one detail authenticating the user name —i.e. the password— this is sometimes termed one-factor authentication. With two-factor authentication‚ something the user ’has’ is also used (e.g. a security token or ’dongle’‚ an ATM card‚ or a mobile phone); and with three-factor authentication‚ something the user ’is’ is also used (e.g. a fingerprint or retinal scan)

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

Wireless Network A wireless network‚ as its name would suggest‚ is a network of computers and computer peripherals that are connected to each other without wires. This enables ease of communication‚ especially for mobile computing platforms. Further‚ there are a number of other advantages to a wireless network that make them increasingly common in both the workplace and at home. Nearly all wireless networks in the world work on a standard set up by the Institute of Electrical and Electronics
