and channel access control mechanisms‚ and works to transmit data from one Network Interface Card (NIC) to another across a connected network. Carrier Sensed Multiple Access with Collision Detection (CSMA/CD) is the process used by non-switched Ethernet to detect a clear channel between devices helping to decrease the chance of data “colliding” during transmission. Utilizing MAC protocol‚ a devise will “listen” for other traffic between connected devises. If no traffic is detected‚ the device will

1. You are installing a network card in a computer that has several devices configured. There is a printer on LPT 1‚ a mouse on COM 1‚ a modem on COM 2‚ and a SCSI host adapter occupying IRQ 10. The computer also has a sound card using IRQ 5. If your network card supports IRQs 3 through 5 and 9 through 11‚ which of the following IRQs could you set it for in this computer? IRQ7 IRQ3 IRQ10 None of these IRQ4 IRQ5 2. A 100BaseVG network is build on a ______ topology with all computers attached

Routers. In addition‚ some method of connecting these building blocks is required‚ usually in the form of galvanic cable (most commonly Category 5 cable). Less common are microwave links (as in IEEE 802.12) or optical cable ("optical fiber"). An ethernet card may also be required. Network interface cards A network card‚ network adapter or NIC (network interface card) is a piece of computer hardware designed to allow computers to communicate over a computer network.

The data communication media for the networks is UTP CAT5. This cabling follows the Ethernet standards for TCP/IP and ensures decreased propagation and noise. I understand the motivations for creating a network and can apply these technologies to improve communications and access to information‚ as well as support and maintain the infrastructure

extra that shouldn’ t be. So what is overhead in networking or how it’s affecting the entire network performance? It does not seem irrelevant for us to know something that most of us deal in everyday life knowingly or unknowingly. The technology like Ethernet that we use most to transfer data over the network is the main focus on this paper to measure the overhead. We all know the bandwidth we get from ISP‚ that’s what we paid for‚ but are we fully able to use the full bandwidth? No‚ we can’t but why
