In such cases, it would be common for the servers to operate without a dedicated display or keyboard.
However, the size and speed of the server's processor s , hard drive, and main memory might add dramatically to the cost of the system. On the other hand, a workstation might not need as much storage or working memory, but might require an expensive display to accommodate the needs of its user.
Every computer on a network should be appropriately configured for its use. On a single LAN, computers and servers may be connected by cables or wirelessly.
Wireless access to a wired network is made possible by wireless access points WAPs. These WAP devices provide a bridge between computers and networks.
Net-Centric Computing: The Future of Computers and Networking
A typical WAP might have the theoretical capacity to connect hundreds or even thousands of wireless users to a network, although practical capacity might be far less. Nearly always servers will be connected by cables to the network, because the cable connections remain the fastest.
Workstations which are stationary desktops are also usually connected by a cable to the network, although the cost of wireless adapters has dropped to the point that, when installing workstations in an existing facility with inadequate wiring, it can be easier and less expensive to use wireless for a desktop.
See the Topology , Cabling , and Hardware sections of this tutorial for more information on the configuration of a LAN. Dedicated transoceanic cabling or satellite uplinks may be used to connect this type of global network.
Using a WAN, schools in Florida can communicate with places like Tokyo in a matter of seconds, without paying enormous phone bills. Two users a half-world apart with workstations equipped with microphones and a webcams might teleconference in real time.
A WAN is complicated.
It uses multiplexers, bridges, and routers to connect local and metropolitan networks to global communications networks like the Internet. Advantages of Installing a School Network User access control. Modern networks almost always have one or more servers which allows centralized management for users and for network resources to which they have access.
User credentials on a privately-owned and operated network may be as simple as a user name and password, but with ever-increasing attention to computing security issues, these servers are critical to ensuring that sensitive information is only available to authorized users. Information storing and sharing. Computers allow users to create and manipulate information. Network invaders may use public systems as proxies to perform an action known as IP Spoofing.
Application Layer These firewalls work on the application level, and filter out packets coming and going from a specific application. Cables[ edit ] A wired network must contain some type of medium to transfer data over.
The types of media can include: Coaxial Cable - A cable consisting of insulated copper or aluminum. This type is most common, and used for cable television and CCTV networks. Power line communication - This refers to the transfer of data over electrical wires. Ethernet cables - Also known as a twisted pair because the individual wires are twisted into pairs. This is the most common for home networks. Fiber Optic - This is a strand of glass fiber that carries pulses of light to transmit data.
Fiber optic cables can transfer multiple steams of data on different wavelengths of light; this increases data transfer rate.
These cables do not have a high data loss rate and thus are used for long distance lines, such as under sea cables. These cable types are organized in roughly slowest transfer speed to fastest.
Ethernet cables require a repeater a device that cleans and reproduces the data at a higher strength about every meters. Fiber optic cables on the other hand, only require a repeater after about kilometers.
This make them suited for undersea cables such as the Transatlantic cable. Computer Network Diagram Symbolization[ edit ] A computer network diagram is an illustration portraying the nodes and connections amongst nodes in any telecommunications network. Basic symbols and pictures are used to portray common network appliances. In certain depictions you can see lines connecting CPU's and a single switch.
That switch may also be connected to a printer or fax machine and a router. The clouds you see in many pictures are used to portray the external networks connections between external and internal devices, without showing the details of the outside network.
In some cases representative hypothetical devices may be pictured instead of showing every existing node. For example, if a network appliance is intended to be connected through the Internet to many mobile devices, only a single mobile device may be shown.
Internet Protocol IP , is a set of rules that facilitate all of the actions that happen within the connected parts of the World Wide Web. An IP address allows people to send and receive data over the Internet connections so that they reach their intended destination, thus making all two-way communications possible in the modern era.
IP Address can also be static or dynamic. Dynamic IP addresses are randomly assigned to a computing device each time it connects to the internet.

Workstations which are stationary desktops are also usually connected by a cable to the network, although the cost of wireless adapters has dropped to the point that, when installing workstations in an existing facility with inadequate wiring, it can be easier and less expensive to use wireless for a desktop.
Students can begin an assignment in their classroom, save part of it on a public access area of the network, then go to the media center after school to finish their work. Private IP addresses are usually used because they provide a completely separate set of IP addresses that still allow access on a network without taking up any of the public IP address space.
Ethernet Hub[ edit ] A Ethernet Hub multi-port repeater is a small rectangular electronic network hardware device that connects many computers and other network devices to form a single central switching point. These cables do not have a high data loss rate and thus are used for long distance lines, such as under sea cables.
The school can provide network users with access to the internet, via an internet gateway. For example, Although a network server is no more susceptible to failure than any other computer, when the files server "goes down" the entire network may come to a halt. You will learn how to create, record, and visualize data using Xively service.
