facilitates the teaching and learning of complex technology concepts. (Cisco Networking Academy, 2014) Cisco Systems created Packet Tracer so people interested in becoming Cisco Certified Network Associates could practice, learn and get the CCNA certification. The tool was made for practice ,and learning only; and it cannot compare to the real Cisco Switches and Routers on real enviroment. Packet Tracer can be utilize for simulation with the different kinds of protocols, devices

Network Design Network Design is very important when it comes to implementing a connection between a computer and a server. According to Network world Websites, Network is defined as a “connected collection or devices and end systems, such as computers and servers, that can communicate with each other”(McQuerry). Network carry data in many types of environment, such as homes, small businesses, and large enterprises. Network Locations Is one of the major factors. There are different types and locations
I am a person with one of the most ancient cultures, studying a very modern and continuously changing profession upon third millennium. My culture has instilled insight within me, encouraging me to study diligently and acquire knowledge as much as possible. This philosophy propelled me to study master of computer science (Distributed computing) at Universiti Putra Malaysia (UPM), and I’m a former B.Sc graduate of computer engineering (Software) at Islamic Azad University of Sari (IAUS). To take
I chose to major in Electronic and Communication Engineering because it is an evolving field and I am enthusiastic about the challenges that it presents. The depth and scope of this discipline and its contribution to the way we live and work in the world today has been phenomenal. Right from school, I had a penchant towards Mathematics and Science. This basic interest led me to take up Mathematics, Physics and Chemistry as my major subjects in high school so as to form the basic building blocks
My fascination for computers started from my school days and gift of a personal computer by my parents further boosted my quest to learn and understand both hardware and software. By enrolling in ‘Jetking’ Institute, I got acquainted with hardware and operating systems such as Red Hat Linux, Windows XP and Windows Server 2003. On completion of high school, I decided that computer science was the most suitable career option. Progressing to Undergraduate studies in Computer Engineering and further
Who is a hacker? Most people see a hacker as someone who exploits vulnerabilities of electronic devices and system, network, and computer to use in malicious activity. About.com wrote "Hacking is any technical effort to manipulate the normal behavior of network connections and connected systems. A hacker is any person engaged in hacking. The term "hacking" historically referred to constructive, clever technical work that was not necessarily related to computer systems. Today, however, hacking and
STATEMENT OF PURPOSE (SOP) Major: Master of Science in Computer Science (MS in Computer Science) When I was 13 years old my father presented a personal computer as a birthday gift to me. Having seen the profound impact which personal computers have made and witnessed its prolific growth right from my childhood, it has been a great fascination for me to study computers and related technologies. This childhood fascination made me opt for Computer Science as mainstream diploma subject. With
The idea of communication and networking has been always my interest, starting from 1999, when I was just 11 years old and I had a very ordinary computer. I had always wanted to connect my computer to other devices or other computers. But I could not because of lack of knowledge as well as information at that time. Moreover, lack of communication devices was another reason. My dream came true when I was accepted at College of science in Computer Department. Immediately after graduating from the
The first time I happened to know about computer networks was when in my third semester, I attended a lecture on networking by one of the university professors. This lecture had left me awed. With the increased curiosity in this field of networking, I enrolled myself in a course called "Networks". Within this course, I got an opportunity to work on various switched networks, FTP, DNS, DHCP, NFS and Telnet configurations, shell programming, apache web server, structured cabling, firewall services
Concepts of Circuit Switching Systems A circuit switched system is one where a dedicated connection must be set up between two nodes before they may communicate. For the duration of the communication, that connection may only be used by the same two nodes, and when the communication has ceased, the connection must be explicitly cancelled. A good example of this is the early telephone exchange systems, where one caller would ask the operator to connect them to a receiver, where the end result
Computer networking has changed our lifestyle tremendously. It provided opportunity for many people to work at home. Today we use computer networking to do our banking from home, communicate with relatives, shop online, and even to entertain ourselves with music or by playing video games. We can get access to information on almost any subject we can imagine at the click of a mouse. Companies can save millions of dollars by sharing resources via computer networks rather than by shipping or traveling
We live in a technologically saturated world. Everyone is connected to one network or another by any number of devices, so that begs the question: “Just how secure are those connections?” Earlier this year, headlines were made when a hospital in California (and several others in other states shortly thereafter) had its network system hacked; its files and patient information encrypted and held ransom. To gain access to their own files, the hospital paid the hackers for the encryption key so that
The Future of Nursing Being a registered nurse affords one the option of working in many diverse healthcare settings. In any practice setting the climate of health care change is evident. There are diverse entities involved in the implementation and recommendation of these practice changes. These are led by the Robert Wood Johnson Foundation (RWJF), the Institute of Medicine (IOM), nursing campaign for action initiatives, as well as individual state-based action coalitions. Nurses need to be
My strong curiosity towards the field of Cybersecurity dates back to my pre-university days when I started reading sci-fi novels. Digital Fortress, a techno-thriller novel written by Dan Brown, explored the theme of government surveillance, security and civil liberties. This theme is brought out in the book by portraying cryptographic techniques, security policies and implications of these policies. This gravitated me towards the field of security. With little programming experience, I was eager
Networking Topologies and TCP/IP Protocol Bus Topology It just doesn't get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus, backbone, or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions
