Bus Topology http://compnetworking.about.com/od/networkdesign/a/topologies.htm http://fallsconnect.com/topology.htm Bus topology Bus topology refers to a single cable that connects all the workstations‚ servers‚ printers and other devices on the network. The cable runs from device to device by using tee connectors that plug into the network adapter cards. Each end device has a terminator on one end of the tee and a cable going out to the next device on the other end‚ while all devices in the

ISO/OSI Reference Model: Open Systems Interconnection (OSI) is an effort to standardize networking that was started in 1977 by the International Organization for Standardization (ISO)‚ along with the ITU-T. The world has not always been so simple. Once upon a time‚ there were no networking protocols‚ including TCP/IP. Vendors created the first networking protocols; these protocols supported only that vendor’s computers‚ and the details were not even published to the public. As time went on

The four nitrogen bases are Adenine‚ Thymine‚ Guanine and Cytosine. 2. B. Nitrogen bases‚ and hydrogen bonds make the "ladder". C. The phosphate and deoxyribose sugar makes up the backbone of the "ladder". D. They are anti-parallel because the both sides aren’t parallel. 4. Adenine is always attached

Networking In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. Networking software applications are available to manage and monitor networks of all sizes‚ from the smallest home networks to the largest enterprise networks. Networks classification 1.

blocks called nucleotides; adenine (A)‚ thymine (T) guanine (G) and cytosine (C). Purine base always pairs (by hydrogen bonding) with a pyrimidine base thus adenine always pairs with thymine and guanine always pairs with guanine. Guanine and cytosine have 3 hydrogen bonds while adenine and guanine have 2. The three-dimensional model created by Watson and Crick is composed of a nucleotide base strand twisted into the shape of a double helix and held together by hydrogen bonds forming a spiral staircase

Computer Networks Does anyone really know what networking is? “In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come. Network research can be traced back to around the 1960’s.
