Connectors normally called “input-output connectors” (or I/O for short) are interfaces for linking devices by using cables. They generally have a male end with pins protruding from it. This plug is meant to be inserted into a socket, which includes holes for accommodating the pins. However, there are “hermaphroditic” plugs which can act as either male or female plugs, and can be inserted into either one. The computer’s motherboard has a certain number of input-output connectors located on the “rear panel.“ Most motherboards have the following connectors: Serial port, which uses a DB9 connector, for connecting older devices Parallel port, ...

Connectors Repeaters Hubs NIC’s Bridges Switches
Classes of transmission media GUIDED MEDIA Guided media, which are those that provide a conduit from one device to another, include twisted-pair cable, coaxial cable, and fiber-optic cable. Twisted-Pair Cable Difference between UTP & STP STP cables are shielded while UTP cables are unshielded STP cables are more immune to interference and noise than UTP cables STP cables are better at maximizing bandwidth compared to UTP cables STP cables cost more per meter compared to UTP cables STP cables are heavier per meter compared to UTP cables UTP cables are more prevalent in SOHO networks while STP is used in ...

BUS TOPOLOGY A Bus topology consists of a single cable—called a bus— connecting all nodes on a network without intervening connectivity devices Network maintained by a single cable Cable segment must end with a terminator Uses thin coaxial cable(backbones will be thick coaxial cable) Extra stations can be added in a daisy chain manner. Standard is IEEE 802.3 Thin Ethernet (10Base2) has a maximum segment length of 200m Max no. of connections is 30 device Four repeaters may be used to a total cable length of 1000m Max no. of nodes is 150 Thick Ethernet(10Base5) used for backbones Limited to ...

Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network. Topology Types: physical logical Physical topology refers to the placement of the network’s various components, including device location and cable installation while logical topology shows how data flows within a network, regardless of its physical design. PHYSICAL V/S LOGICAL TOPOLOGY The actual layout of a network and its media is its physical topology The way in which the data access the medium and transmits packets is the logical topology. A glance at a network is not always revealing cables emerging from a Hub does ...
