      How to Increase a WiFi Signal

      The first thing you can try to increase a WiFi signal is to move the laptop computer or mobile device closer to the source of the network that is being accessed. If you have control over the router of the network, you can increase the wireless signal by placing the router on a high area

    • Ethernet Cabling

      Ethernet Cabling

      Ethernet is a media access method that is specified at the Data Link layer and uses specific Physical layer cabling and signalling techniques. It is important to be able to differentiate between the types of connectors that can be used to connect an Ethernet network together. I'll discuss the different unshielded twisted-pair cabling used today

    • How fast is ADSL Speed?

      How fast is ADSL Speed?

      ADSL (Asymmetric Digital Subscriber Line) options are available in many locations. The speeds will vary for the service in many ways depending on several factors. The reason why it is called an Asymmetric Digital Subscriber Line is simple, as the speed for downloads will be significantly faster than the upload speed. This is because consumer DSL services are

    • The OSI Model – What It Is; Why It Matters; Why It Doesn’t Matter.

      The OSI Model – What It Is; Why It Matters; Why It Doesn’t Matter.

      The OSI Model was created based on recommendations from the International Organization for Standardization (ISO) in 1980, which started expanding on the DoD model in the late 1970s. The current standard was published in 1996. The official title for the model is the ISO OSI (Open Systems Interconnection) Reference Model since it describes or relates

      How to Flush DNS

      When surfing the Internet, a problem that can arise for consumers is getting a number of DNS errors or 404 errors in the web browser despite a working Internet connection. If this is the case, then learning how to flush DNS for your computer’s operating system (OS) is key to restoring the proper quality of

      802.11a

      802.11a is one of the many standards used for high speed wireless networks, usually referred to as Wifi. This standard was created by the IEEE (Institute of Electrical and Electronics Engineers) in 1999 and uses several different frequencies including 5.15-5.35/5.47-5.725/5.725-5.875 GHz to send and receive data from one electronic or computer device to another. There

      Fiber Optics

      Fiber optic technology makes use of light to carry digital signals via optical cables. Fiber optic cables are very thin glass wires made from extremely pure optical glass. This technology is based on the concept of light reflection. In the case of fiber optics technology, light carrying digital signals is reflected inside the optical cable

    • Frame vs Packet

      Frame vs Packet

      A packet and a frame are both packages of data moving through a network. A packet exists at Layer 3 of the OSI Model, whereas a frame exists at Layer 2 of the OSI Model. Layer 2 is the Data Link Layer. The best known Data Link Layer protocol is Ethernet. Layer 3 is the

      How Does Wireless Networking Work?

      Wireless networking has grown from only being a tool employed by academia and Fortune 500 companies to being deployed in locations such as McDonald’s, Starbucks, and gas stations for free consumer use over the past decade. Consumers can install a wireless network in the home for minimal cost today, and many home theater set-top boxes
