Is UDP a fair protocol why or why not?

UDP is slower than TCP because it does not confirm that the package was delivered, as result UDP it not used for secured connections. Because it does not have delivery conformation it works faster than TCP, that's one of reasons why it's used for many internet pagers.

Why does an application have more control of what data is sent in a segment?

An application has no control over the size of a data segment in a network packet. An application would not know what the segment size would be, because that information is in the OSI layers and not really retrievable for the application, nor should the application care.

The OSI layers are responsible for taking care of transporting, routing, and other network tasks for a message coming from an application. The application and the network protocols are independent of each other.

Networks negociate segment sizes (MTU) during connections, outside of what the application would see.

Why is the OSI model useful in network design and assessment?

The OSI model is useful in network design and assessment because it makes network communications more manageable by dividing the processes up into smaller parts. The processes are broken up into 7 layers and each layer serves the one above it.

Define controlled access and list three protocols in this category?

In controlled access, the stations consult one another to find which station has the right to send. A station cannot send unless it has been authorized by other stations. There are 3 protocols

How can LAN card be checked?

It can be checked easily. You can just search someones LAN card as simple as 123 like some hackers can easily find it in a few seconds.

Addition: If you need a LAN card to be checked you need to run the manufacturers diagnostics utility. This can be done after determining that the card is not working on the network (for example, by pinging the address)

How old do you have to use a Peer to Peer network?

There is no age restriction to use the network.

Although most chat rooms require you to be 18 or 21 years of age.

What is the different between ip and tcp?

Ip is the protocol that figures out how to get data to a certain location on the network.

TCP is the protocol that breaks the data down and gets it ready to be transported. And then again on the other computer, TCP is what builds up the data into its original format before it got broken down by TCP on the first computer.

What is a Zero Slot LAN and Its Advantages Disadvantages?

A zero-slot LAN is a local-area network (LAN) that uses existing serial and/or parallel communication ports on the computers in the network instead of requiring network interface cards (NICs) that would occupy an expansion slot.

Advantages

It leads to transmitting between computers over a serial or parallel port, thus freeing up an expansion slot normally used by LAN cards (NICs).

Disadvantages

Zero-slot LANs are typically slower than LANS that use NICs and are limited to two or three network nodes.

What is the subnetting of 192.168.1.0 24 to provide for 100 hosts?

the /24 at the end of your IP is stating that your subnet is going to be 255.255.255.0 wich would give you 254 hosts so you have alot of room to expand if you are only looks for 100 hosts

What is the difference between a lan and a wan according to access them?

From the user's point of view, accessing a LAN or WAN is the same. If packets need to be forwarded from a LAN via a WAN connection that is taken care of automatically by the router.

What is a good way to contain network traffic to a certain area in a network?

One of ways to do that is to use VLAN, but you need switch or router supporting. Also just single router without VLAN can separate networks isolating broadcast and collision domains. Some switches can limit broadcast domains too but they are rather expensive.

Why to use tcp header?

a tcp header contains the information of the source and destination networks and well as what port to access with out it the packet would not know where to go
