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.

It is the process of forwarding packets in a network so that it reaches its intended destinations. To perform routing there are numbers of routing algorithm .
What does code is case-sensitive mean when it is all numerical?
It means that you are writing code computer generates different names for x and X, also it will understand commands or will not under stand it at all (c++: cout and Cout are different).
What is metropolitan area network?
A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.
A switch will receive the first 64 bytes of a frame before forwarding?
There are actually three options here. Different switches work differently. (1) The switch forward the frame as soon as it knows the destination address. This gives the lowest latency, but more errors. (2) The switch waits until it receives at least 64 bytes. This avoids fragments of less than 64 bytes being accidentally forwarded. (3) The switch stores the entire frame and then resends it. This allows the switch to check the CRC, and reject bad frames. Whatever method it uses, in any case the switch may have to store frames (buffering) if the outgoing port is busy.

What is a hacker most likely not going to steal from a networked computer?
It depends on the hacker.
Most hackers seek to damage, deface, or destroy the computer's normal function.
Some seek to steal credit cards, phone numbers, and mailing addresses for identity theft, spam, or fraud.
A few seek to obtain email account passwords, game passwords, IM passwords, and other passwords.
Rarely, some may seek private data such as pictures, work documents, or industry secrets (such as R&D or marketing papers).
I've never heard of a hacker attempting to steal games themselves from a PC, since games can easily be stolen by easier, less risky means.
Some also hack solely to get in- and never touch anything. Just to prove they can. This is popular to do against security personnel, administrators, and large corporations or banks due to the extreme challenge.
What are the proper requirements for a 10Base2 network?
The requirements for a 10Base2 network:
RG58u Coaxial cable
T-connectors
BNC's
Terminators
Ground, usually a ground chain

802 represents the last two digits of the year in which the first meeting was held (1980) and the month (February).
A computer running Windows (except Windows NT) will use a system named APIPA (Automatic Private Internet Protocol Addressing) to assign itself an IP address.
Using APIPA, the computer will assign itself an IP address from the 169.254.0.0 /16 network which is part of the private class B IP range. The valid address range for this network is 169.254.0.1 to 169.254.255.254 The subnet mask for this network is 255.255.0.0
The computers will use ARP (Address Resolution Protocol) to confirm that the IP address that it has chosen is unique and not being used by any other computer on the local network. When the DHCP server becomes available again, the computers will contact it and attempt to lease or renew a new IP address.
No. A peripheral device is something not part of your computer. So, disk drives (CD Roms DVDs) mice, printers, etc.. Even certain applications can be considered a peripheral devices.
To clarify more. internal peripheral devices such as a CD ROM DVD or tape drive are in fact solely a peripheral device however just as I did; they are commonly referred to as an Internal peripheral device.
Why do we share information through intarnet catting?
We share information through instant messaging to facilitate quick and efficient communication within organizations. This allows for real-time collaboration, enabling teams to exchange ideas and updates rapidly. Instant messaging also fosters a more informal atmosphere, encouraging open dialogue and stronger relationships among colleagues. Additionally, it helps reduce email clutter and streamlines information sharing.
may be ...may be not
It is truly sad that ignorant people post such things as "may be or maybe not..
this is no help!
How do you upload in dan ball the powder game?
I believe there is an upload button above "SAVE" and "LOAD". However, usually a message should appear saying "Upload past 12 hours to a total of 50". This means to upload past 12, (I don't exactly know if it is hourly or every 12 hours, but I know it means past 12 hours) to a total of fifty meaning only fifty people can upload which is the maximum people that can upload after 12 hours. I have not managed to upload yet, so I am trying to stay up until midnight and awake at noon, but when I have that chance to upload I will tell you exactly how I did it. Oh and remember you have to be a member. One thing I don't exactly like about Dan Ball is that you have to remember a code in which is easily forgotten. So when entering the code, put something like your birth date or your phone number, it helps a lot.
If you really want to upload, this is what you should do:
Press the button upload a couple times per day at different hours. So let's say you press upload and it says "Upload past 12 hours to a total of 50. Then you wait maybe a hour and press it at 4:00 pm. Let's say it allows you to input a title and upload. So don't simply rush and make a quick crappy upload and upload it. Make a good upload for the rest of the day. So when tomorrow comes, come around the same time and press upload. If it allows you, great. If it doesn't, that's ok. I'll explain why.
So you pressed upload at 4:00 pm and it allowed. Maybe the uploading time started at 3:45 and it took 20 minutes for 50 people to fill up the space. So the time frame is 3:45-4:05pm. (Just example) So then after 12 hours is 4:05 am, and it takes 46 minutes for 50 people to upload. So now the time frame was 4:05am-4:51am. Now 12 hours later let's say the time frame is 4:51 - 4:53pm ( it happens that quick sometimes!) As you can see, the uploading times keep changing day by day. So this was how I would estimate. If the game allowed me in at 4:00 I would remember that and tomorrow I would come at 4:30. Then 5:00. Just saying. And don't make a crappy upload in a rush to put something on. That will ruin your accounts reputation and you might get 2 votes or something. So just use the time if your missed the upload frame to make you upload better. Hope this helped you.

What is the maximum number of bits that can be borrowed to create a subnet for a Class C network?
You can borrow 6 bits. Which would create a 255.255.255.252 subnet mask, but this subnet only contains 2 usable IP addresses.
7 bits would be 255.255.255.254, but that subnet is too small to have any use in the real world.
What is the difference between framed and unframed?
Unframed E1, you will be able to use the full bandwidth of the circuit of 2048 kpbs. Normally, for various reasons, this mode is not given to customers by telco.
Costly service
Framed E1 ,you will be able to use 1984Kbps only from 2048Kbps where timeslot 0 is reserved for sync and signaling purposes.
Less costly when compared with Unframed.
Hypertext transfers are transfers only consisting of hypertext.
