Computer Networking
Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

What are the advantages of Non-Routable protocol?
A non-routable protocol has less overhead and processing to do, and is more compact. This leads to faster transmission.
What is the process name of school computer's Vision Client?
MeSuAx.exe. You will have to end the process tree by right clicking. If you try to end the process a pop-up will likely appear that says "access denied". Good Luck!
What is the beginning ip address of this network id 198.162.10?
You mean 192.168.10?
The first usable IP in that network would be 192.168.10.1, and ending with 192.168.10.254.
What is the purpose of using a coaxial splitter?
The purpose of using a coaxial splitter is so that one can connect more than one device to a single coaxial line. For instance connecting two TV's to one coaxial line for cable television.
How can you mitigate the security risk caused by Telnet?
It is a good idea to change the information associated with Telnet. You should change your password, username and any accounts associated with the company.
What is an arp request packet for?
ARP stands for Address Resolution Protocol. This is IP's way of requesting a MAC address (or hardware address) from a host located at a certain IP address. In order for a host on a network to send a unicast packet across the network, it must know both the source and destination MAC addresses. ARP is used to obtain a MAC address similar to the way DNS is used to obtain an IP address from a domain name (www.anydomain.com).
The Domain Name System (DNS) has a tree structure or hierarchy, with each node on the tree being a domain name. A subdomain is a domain that is part of a larger domain, the only domain that isn't also a subdomain is the root domain.[2] For example, "mail.example.com" and "calendar.example.com" are subdomains of the "example.com" domain, which in turn is a subdomain of the "com" top-level domain (TLD). A "subdomain" expresses relative dependence, not absolute dependence: for example, wikipedia.org comprises a subdomain of the org domain, and en.wikipedia.org comprises a subdomain of the domain wikipedia.org. In theory, this subdivision can go down to 127 levels deep, and each DNS label can contain up to 63 characters, as long as the whole domain name does not exceed a total length of 255 characters. But in practice some domain registries have shorter limits than that.
Discus the different between omnidirectional and unidirectional waves?
An omni directional antenne receives or transmits signals from all directions as in 360 degrees. A directional antenne is aimed in a specific direction so that it may direct an outgoing signal to or receive a signal from a specific source.

What are special IPv4 addresses and what are they used for?
0.0.0.0 --> Current network (only valid as source address) 10.x.x.x --> Private address space for class A networks 14.x.x.x --> Public data network 127.0.0.1 --> Loopback (refers to own computer) 128.0.0.x --> Reserved (IANA) 169.254.0.x --> Zeroconf network 172.16.x.x through 172.31.x.x --> Private address space for class B networks 191.255.0.x --> Reserved (IANA) 192.0.0.x --> Reserved (IANA) 192.88.99.0 --> IPv6 to IPv4 relay 192.168.x.x --> Private address space for class C networks 198.18.0.0 --> Benchmark tests 223.255.255.0 --> Reserved (IANA) 224.0.0.x --> Multicasting 240.0.0.x --> Reserved 255.255.255.255 --> Broadcast
I think I've got that right.
How Many user access remote desktop?
With MS-Windows XP Professional & the Vista line I believe you can use the Remote Desktop feature just one person at a time. With MS-Windows 2000 Server/Advanced Server or MS-Windows Server 2003 Std/Enterprise Editions, it's pretty much unlimited -- it depends on how many CAL's you've purchased (Client Access Licenses). Your server's CPU (or CPU's) and memory must be able to handle the load as well. If you want extra performance with a LOT of users on at the same time, you can make it totally "enterprise-capable" and faster/leaner by using Citrix's add-on software www.citrix.com

What occurs when computers are configured to receive their network configurations dynamically?
Each computer requests configuration information from a server.
Is a simple technique that addresses QoS issues by prioritizing traffic?
DiffServ (Differentiated Services)
How do you connect two computers without using LAN ports?
Get a USB Direct Connect Cable, it is a USB cable that has a special crossover and more to it. This makes the USB cable act like an old NULL Modem cable from the early days. You then plug it into the USB ports on each computer install the software drivers and then set up file sharing and whatever else it has you do to make it network and your good to go.
Do Not use a regular USB cable, you will fry things...
What does UPC in fiber optic mean?
"UPC" its attenuation is smaller than the PC and it has a spherical cross-section
Which type of server assigns ip addresses to clients on a temporary or lease basis?
The DHCP server (Dynamic Host Configuration Protocol)
What is DHCP?Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers (i.e., a scope) configured for a given network.DHCP assigns an IP address when a system is started, for example:
- A user turns on a computer with a DHCP client.
- The client computer sends a broadcast request (called a DISCOVER or DHCPDISCOVER), looking for a DHCP server to answer.
- The router directs the DISCOVER packet to the correct DHCP server.
- The server receives the DISCOVER packet. Based on availability and usage policies set on the server, the server determines an appropriate address (if any) to give to the client. The server then temporarily reserves that address for the client and sends back to the client an OFFER (or DHCPOFFER) packet, with that address information. The server also configures the client's DNS servers, WINS servers, NTP servers, and sometimes other services as well.
- The client sends a REQUEST (or DHCPREQUEST) packet, letting the server know that it intends to use the address.
- The server sends an ACK (or DHCPACK) packet, confirming that the client has a been given a lease on the address for a server-specified period of time.
