      Port Scanner

      A port scanner is a program which attempts to connect to a list or range of TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) ports on a list or range of IP addresses. Port scanners are used for network mapping and for network security assessments. The first decision to make when running a port

    • Coaxial Cable

      Coaxial Cable

      Coaxial cable, also called coax, is used to transmit radio frequency (RF) signals. It has low emission losses and provides protection from electromagnetic interference, allowing signals with low power to be transmitted over longer distances. Coaxial cable is comprised of an inner core, insulator, shield, and outer cover. It is called coaxial because these sections

    • IKE (Internet Key Exchange)

      IKE (Internet Key Exchange)

      The term Internet Key Exchange refers to the networking protocol that designed to configure a SA (security association) within the IPsec protocol suite of applications. Internet Key Exchange (or IKE) is constructed on top of ISAKMP and the Oakley protocol and is often used in the VPN tunneling process. X.509 certificates are used for authentication

      What Are the Effects of Computer Hacking?

      Hacking as a Destructive Tool The common stance on hacking with the average person is that it is morally wrong. There have been several instances where hacking has proven to have caused problems. Hacking can create a variety of damages to people, groups and systems of broad spectrum. Negative Hacking Interactions: Identity Theft – Some hackers can

    • Fiber Optic Patch Panel

      Fiber Optic Patch Panel

      Fiber optic patch panel, also known as the fiber distribution panel, is used mainly in fiber optic cable management. It helps network technicians in minimizing the clutter of wires when setting up fiber optic cables. It terminates the fiber optic cable while providing access to the cable’s individual fibers for cross connection. They are also

    • UTP (Unshielded Twisted Pair)

      UTP (Unshielded Twisted Pair)

      UTP (Unshielded Twisted Pair) is a regular copper wire that joins many home and many business computers to the telephone company. UTP is the most common form of twisted pair wiring, because it is less expensive and easier to work with than STP (Shielded Twisted Pair). It is used in Ethernet 10Base-T and 100Base-T networks

    • Analog Telephone Adapter

      Analog Telephone Adapter

      An Analog Telephone Adapter (ATA), also known as the Analog Telephony Adapter, is an electronic device used to enable one or more analog telephones or facsimile machines for Voice over Internet Protocol (VoIP) calls and faxes. An Analog Telephone Adapter basically creates a physical connection by use of telephone and Internet cables between a conventional

    • 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

    • DHCP Reservation

      A DHCP reservation is a permanent IP address assignment. It is a specific IP address within a DHCP scope that is permanently reserved for leased use to a specific DHCP client. Users can configure a DHCP reservation in their DHCP server when they need to reserve a permanent IP address assignment. Reservations are used for

    • Routing Software

      Routing Software

      Most networks currently run on hardware-based routers from vendors like Cisco, Foundry, and Juniper. Computing power has advanced to the point where this is not necessary. General purpose computing platforms can replace these expensive dedicated hardware routers. These software routing platforms usually run on some version of free or inexpensive Unix. These are a few
