About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Guns have been around for centuries, and their history is fascinating. Early guns were simple devices that used black powder to launch a lead ball or shot at a target. These early guns were often inaccurate and dangerous to use, but they were the best weapons available at the time. As gunpowder and metallurgy improved, guns became more reliable and accurate. In the 18th and 19th centuries, guns became increasingly sophisticated, with the invention of rifled barrels, breech-loading mechanisms, and cartridge ammunition. Today, guns are more advanced than ever, but their basic function remains the same: to provide a rapid and accurate way to deliver deadly force. Whether you’re a hunter, a target shooter, or a member of the military, guns play an important role in our lives.

 

Where Did Guns First Appear

The origins of guns are a matter of debate. Some historians believe that the first guns were invented in China during the 13th century, while others believe that guns were first used in Europe during the 14th century. The first official firearm was called the fire lance. It consisted of a tube that was filled with gunpowder and then attached to a spear. The gunpowder would be ignited, sending a burst of flame and smoke out of the tube and towards the enemy.

The First Matchlock Firearm

The first matchlock guns appeared in Europe in the 15th century. It consisted of a curved arm that held a match, and a trigger device that lowered that arm so that the lit match would set off primer powder in the pan attached to it. It was later on replaced by the flintlock in the 16th century, which used a flint held against a steel spring-loaded hammer that struck a spark when rotated into a small opening at the back of its pan, which then ignited the main charge and fired the gun.

19th Century Colt Guns

The first mass-produced, rotating firearms were created in 1835 by Samuel Colt. This was a breakthrough in the industry, as although various revolver designs existed for decades prior, he was the first to apply industrial age mass production. Revolvers went from being extremely rare and costly to own, to being widely available. This also improved reliability and accuracy drastically, which ultimately made the Colt a favorite for soldiers and frontiersmen.

The Winchester Rifle

The Winchester rifle was such a popular and affordable rifle that it became the generic rifle of its time, with the Winchester becoming known as “the gun that won the West.” Winchester’s first repeating shotgun was released in 1887, and it’s widely known as one of the most popular shotguns on the market. One of their biggest breakthroughs was reaching automatic rifles in 1903, which became wildly popular and are still in use to this day.

Automatic Guns

In 1892, the first automatic pistol was created by Joseph Laumann, with many other manufactures soon after releasing their own automatic guns including Browning, Luger, Mauser, and Colt. This eventually led to the modern M1911, also known as the Colt 1911, a pistol that has seen World War 1, World War 2, the Korean War, and the Vietnam War. Today, some variants of the M1911, are still in use by the U.S Army and police law enforcement agencies.
