The system needs 8000 frames per second to maintain 24 simultaneous voice channels. Each frame is 193 bits in length (24 X 8 bits per channel + 1 control bit= 193 bits). 8000 frames per second is multiplied by 193 bits per frame which yields a rate of 1.544Mbps
What is the networks that allow people to share software called?
They are called Peer to Peer networks, or P2P for short.

Multi-Level Multi-Access (MLMA): The problem with
BRAP is the delay when the channel is lightly loaded.
When there is no frame to be transmitted, the N-bit headers
just go on and on until a station inserts a 1 into its mini
slot. On average, the waiting time would be N=2. MLAM
scheme [41] is nearly as efficient under high channel load,
but has shorter delay under low channel load. In MLAM, a
station wants to transmit a frame sends its identification in a
particular format. A group of 10 bits (called decade) is used
to represent a digit of the station number [48].

Which circumstances are APIPA addresses assigned?
According to Microsoft:
How to use automatic TCP/IP addressing without a DHCP server
"A Windows-based computer that is configured to use DHCP can automatically assign itself an Internet Protocol (IP) address if a DHCP server is not available. For example, this could occur on a network without a DHCP server, or on a network if a DHCP server is temporarily down for maintenance."

What are the special IP addresses. Give the special IP address for loopback?
There are several IP addresses that are special in one way or another. These addresses are for special purposes or are to be put to special use.
- Addresses significant to every IP subnet
- Network Address
- Broadcast Address
- Addresses significant to individual hosts
- Loopback Address
- Special Addresses of Global Significance
- Private Addresses
- Reserved Addresses
Which is one of protocols of transport layer?
The two that are most commonly used are called TCP and UDP.
What type of router is best for downloading large files?
Don't think about the type of router, think about the speed of the network you are downloading from. The faster the connection, the faster the download will be.

What is the combination of a IP address and a port number?
If you are looking for an example of a IP address then a port number, here is one:
192.168.0.1:2712
192.168.0.1 is your IP address and the : means a port number so :2712 is the port number.
This also works on websites. For example: wiki.answers.com:2712
Together, the combination of an IP address and a port number is called a socket.
Are devices in a single collision domain in the same broadcast domain?
What is the network architecture?
Network architecture is a broad plan that specifies everything necessary for two application programs on different networks on an Internet to be able to work together effectively.
Why twisted pair of wires is used in instrumentation?
Because, from total 8 wires 4 wires are used for actual data transmission ( i e for bit transmission ) and remaining four wires are wounded to these wires to avoid crosstalk and radio frequency interference (RFI).
Why wont my digital id match up with my i.p address to allow me to load .exe?
The I.P. address is your address on the Internet (or in a separate network). When you download anything, or communicate in some other way on the Internet, your I.P. address is used to send the information to your computer.
there are 2 available protocols used to encapsulate data traffic over a trunk link on a cisco switch
1. 802.1q is proprietary works only between 2 cisco switches
2. ISL is open standard works with any switch..
What is DHCP and DNS in Network Configuring..What are the purpose?
DHCP stands for Dynamic Host Configuration protocol. it is used to distribute the info that devices which connect to your network need such as IP address, subnet mask, default gateway, dns servers and lease time. It is used because it is easier to just setup the router to do this than do it manually.
DNS stands for Domain Name Server. Its job is to translate easy to remember addresses to the IP address that corresponds to the Web server which hosts the website.
How can you connect a router and 2 switch hub in a network?
You need to use "crossover" cable. Search on google and you can find the schematics.
Router <==> Switch ===Regular Cat 5 Switch <==> Switch Crossover cable
Crossover PIN layout of RJ-45 1 Rx+ 3 Tx+ 2 Rc- 6 Tx- 3 Tx+ 1 Rc+ 6 Tx- 2 Rc-
Argumentable:(
B standard (Most comercially bought cables) :
White Orange, Orange, White Green, Blue, White Blue, Green, White Brown, Brown.
Cross over cables are used primarily between to system NIC (Network Interface Card), not network devices.
**Correction**
Cross over cables are used to connect 2 like network devices. ie a switch to a switch, a router to a router , or a computer to a computer. There is one note though, some switches have the ability to detect if it is connected to another switch and will automatically "crossover" the cable for you.
Router--switch--switch--router are all wired with normal patch cables regardless of using a WAN or LAN port.
How do you install router to Cisco switch?
Loaded question. This depends on the Cisco switch and it's a very technically detailed answer - unique to every switch model. The short answer is that switches that are "modular" allow you to have routing functionality inside one or more "modules" or "cards" of the switch. Some switches allow routing to occur on each "line card", other solution allow a switch to share a single "card" to do all the routing for the entire switch. Routing and switching can be configured via a single terminal interface session - known as "native", whereas some switches separate the routing terminal and switching terminal - known as "hybrid". If that isn't enough info, go to cisco.com and use their search engine to find the "installation guides" of your model.
