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 is the submask of ip 155.61.9.188?
Well only way to find that out is at your computer, heres how. Hold the windows key and R (or just open the run menu) and type cmd. Now type in ipconfig /all exactly how i typed it, feel free to copy n paste. Scroll around until you find something labeled subnet mask. Follow the dots to the numbers, and those numbers are your subnet mask.
What is the purpose of the network command in configuring RIP?
to identify the directly connected networks that will be announced in RIP updates
What layer of the OSI model does a proxy server operate in?
generally layer 4, but SOCKS operates at layer 5, which allows it to work well with applications
How do you transfer flash game save data from one computer to another?
1. Insert flash drive.
1. Put a blank CD in burner.
3. Open burning software. ex. Nero.
4. Choose "Burn Data CD" option.
5. When asked to select data to be burnt to disc, select flash drive contents.
What type of address does the IP protocol use to identify a unique network and name?
An IP Address, or Internet Protocol Address. Each device has one.
Which three layer of the osi model make up the application layer?
The three layers that I could think of are User interface, Client side, and server side.
What is the difference between a physical address and a mailing address?
Real memory uses Physical addresses.These are the members that the memory chips react to on the bus. Virtual addresses are the logical addresses that nrefer to a process' address space. Thus, a machine with a 16-bit word can generate virtual addresses upto 64K, regardless of whether the machine has more or less memory than 64 KB

How does a computer convert data into information?
A computer performs certain operations on the data. Suppose we give any input to the computer . The computer then process the data . Finally it gives the information to us as an output that is nothing but the processed data.
Are there any unblocked proxy servers for school computers?
If you are in MPS, you shouldn't go on blocked sites. But some sites are blocked and they are safe. Talk to a administrator about this idea. MPs head board may be contacted you never know!

What type of network cable is used between a terminal and a console port?
1. Its a rollover cable. 2. I'm not doing all your cisco questions. 1. Its a rollover cable. 2. I'm not doing all your cisco questions.
What is need of private IP address?
1) Private IP addtess is an unique number/address assign to a computer within the organization or private network or intranet.
2) Using private IP address we can locate a computer on private network.
What is a common protocol used on the internet?
IP, the Internet Protocol. It handles routing and package transfer between internet participants.
The http- hyper text transfer protocol may be used to view websites. This part of the internet is called the "world wide web" or "www".
Which Windows command will identify the route that a packet takes through a network?
On windows OS the command is tracert X . instead of the X you input either IP or the destination or a domain name, Google.com for example. On Linux OS i think the command is tracepath.
What are three types of wired home networks?
straight through and crossover. of those there is class A and class B.

That's not exactly accurate. There are a SIGNIFICANT number of difference in types of ethernet cable, especially when you buy it non-terminated! First off, there is a huge difference between having a solid core and stranded copper core inside the individual eight wires. Solid core wire exhibits less signal loss through attenuation for long, static runs (295' typ.) from port to port. Stranded wire is flexible for use in short (16' typ.) patch cords for connecting equipment to a data port. Using flex wire for long runs can cause signal loss. Using solid, non-flexible wire for connecting equipment to data ports can cause wires to break.
After that, the assembly of the wires and sheathing can be vastly different. Some are simple twisted pairs of the eight wires in a plastic sheath. Some cables are shielded to eliminate interference from adjacent electro-magnetic sources. Some cable assemblies are rated as waterproof, or for direct burial, or for exposure to UV light, such as sunlight. Some have a strong fiber thread running inside so they don't stretch and break the small wires when being pulled through conduit.
BTW, class A and B wiring standards for straight through cables represent a different order of arranging the 8 colored wires. As long as both ends of the cable use the same arrangement, there is no difference to the end user between an A wired cable or B wired cable.
Straight through cables have the same wire arrangement (either A or B) on each end. They are the "standard" or "default" patch cables used for every day hookups. If not specified, you would use a straight through cable. Crossover cables are wired differently on both ends and are specialty cables. If you don't know what they are, you don't need one unless you are specifically instructed to use one.

What types of routing protocols allow routers to exchange information?
That would be a distance-vector routing protocol. Examples (taught at Cisco Academies) include RIP, IGRP (obsolete in the new version of the curriculum), and EIGRP - but those are only for IP, and there are also distance-routing protocols for other networking protocols, for example, RIP for IPX.
What is a dhcp server advantages and disadvantages?
An issue that many people have with DNS is when they configure it themselves, if you went and added a DNS entry yourself and were to make a mistake whether it was the IP or the url then when you try to access that site you will not be able to.
This is because your DNS will be pointing to a different location, until you fix that entry your DNS will be pointing to the wrong location which means you will be unable to access the site you want to.

Which network protocol is used to automatically assign an IP address to a computer on a network?
There are many different hosting services but the one that was the most beneficial and cost-efficient for me was this one https ://yazing .com/deals/bluehost/4everblest (just remove spaces, it's an affiliate link but it's a great deal with this link as a coupon code)
The two programs can be used to accomplish terminal emulation for configuring a router from a PC. The first program is known as Syntax Processor and the second is known as Shell Commands. Both programs take input from the user and produce output. The first program can be used to input the desired settings for the router and the second program can be used to produce output that will be used to configure the router.
What type of network cable is least affected by EMI?
STP, shield twisted pair, is recommended by most of us who've had A+ certification training.
