“Only Connect…” The Goals of a Liberal Education William Cronon What does it mean to be a liberally educated person? It seems such a simple question‚ especially given the frequency with which colleges and universities genuflect toward this wellworn phrase as the central icon of their institutional missions. Mantra-like‚ the words are endlessly repeated‚ starting in the glossy admissions brochures that high school students receive by the hundreds in their mailboxes and continuing right down to the

Alternating current (AC)‚ which is “food” to PCs and other network devices‚ is normally 110 volts and changes polarity 60 times a second (or 60 Hertz). These values are referred to as line voltage. Any deviation from these values can create problems for a PC or other network device. Power problems fall into three categories: * Overage * Underage * Quality Power Overage Problems During a power overage‚ too much power is coming into the computer. Power overage can take two forms: * A power spike

It will first talk about the Hub and the restrictions and the positive goals the hub can achieve. After‚ it’s going to talk about what the switch can accomplish to help fix the problems the hub caused to the network. To start the hub receives data packet from a sending computer and it sends out to all the computers except the senders on the network. This can cause

Devices ... Hub - commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port‚ it is copied to the other ports so that all segments of the LAN can see all packets. Networking Devices ... Multistation Access Unit (MAU) - a hub or concentrator that connects a group of computers (’nodes’ in network terminology) to a token ring local area network. Networking Devices ...

CHAPTER TWO NETWORKING SYSTEMS AND LOCAL AREA NETWORKS (LAN) A network is a system of two or more computers that are connected in some manner. Each computer on the network has access to the files and peripheral equipment (such as printers or modems) on all the other computers on the network. The origin of local area networks can be traced‚ in part‚ to IBM terminal equipment introduced in 1974. At that time‚ IBM introduced a series of terminal devices designed for use in transaction-processing

Bus Topology Bus networks (not to be confused with the system bus of a computer) use a common backbone to connect all devices. A single cable‚ the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see‚ but only the intended recipient actually accepts and processes the message. Ethernet bus topologies are
