The Dynamic Trunking Protocol (DTP) is a proprietary link layer protocol developed by Cisco Systems for the purpose of negotiating trunking on a link between two VLAN -aware switches, and for negotiating the type of trunking encapsulation to be used. VLAN trunks formed using DTP may utilize either IEEE 802.1Q or Cisco ISL trunking protocols. [1]
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface. Packet Tracer makes use of a drag and drop user ...
The DPT vaccine or DTP vaccine is a class of combination vaccines to protect against three infectious diseases in humans: diphtheria, pertussis (whooping cough), and tetanus (lockjaw). [7] The vaccine components include diphtheria and tetanus toxoids, and either killed whole cells of the bacterium that causes pertussis or pertussis antigens.
Pertussis vaccine is a vaccine that protects against whooping cough (pertussis). [1][2] There are two main types: whole-cell vaccines and acellular vaccines. [1][2] The whole-cell vaccine is about 78% effective while the acellular vaccine is 71–85% effective. [1][3] The effectiveness of the vaccines appears to decrease by between 2 and 10% ...
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible. The TLS protocol aims primarily to ...
DTwP-HepB-Hib vaccine is a 5-in-1 combination vaccine with five individual vaccines conjugated into one. [1] It protects against diphtheria, tetanus, whooping cough, hepatitis B and Haemophilus influenzae type B, [1] which is generally used in middle- and low-income countries, where polio vaccine is given separately. [2][3] By 2013, pentavalent ...
A hexavalent vaccine, or 6-in-1 vaccine, is a combination vaccine with six individual vaccines conjugated into one, intended to protect people from multiple diseases. [1] [9] The term usually refers to the children's vaccine that protects against diphtheria, tetanus, pertussis, poliomyelitis, haemophilus B, and hepatitis B, [1] [9] which is used in more than 90 countries around the world ...
58,700 (2015) [9] Whooping cough (/ ˈhuːpɪŋ /), also known as pertussis or the 100-day cough, is a highly contagious, vaccine-preventable bacterial disease. [1][10] Initial symptoms are usually similar to those of the common cold with a runny nose, fever, and mild cough, but these are followed by two or three months of severe coughing fits. [1]
