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 two methods that a hard drive uses to transfer data between itself and memory?
DMA (direct memory access) transfer mode or PIO (programmed input/output) transfer mode
What provides a central access point for all of the network connections on a computer?
Windows Vista Network and Sharing Center
What are the advantages to a workgroup?
WORKGROUP NETWORK A workgroup network, also called a peer-to-peer, is commonly used for home and small business networks. In this type of setup, computers communicate directly with each other and share resources. The computers in a workgroup are called peers because they are all equal. Each user decides on the resources their workstation will share with others on the network. Resources that could be shared include printers, scanners, folders and files. Advantages of Workgroup: * Easy to set-up for small networks * No need for a dedicated network administrator * Less expensive to set up * Can easily share files, folders, printers etc.

What command injects a default route into an OSPF network?
CCNA Guide to Cisco Networking Fourth Edition Ch.8 Answer: OSPF is configured using the router ospf [process id] command.
Which command shows the number of packets sent and received?
Show ip eigrip traffic.
Use 'netstat' for this purpose.
Can a LAN have two DHCP servers?
Yes, a LAN could have two DHCP servers, but it wouldn't make much sense. Typically each LAN has it's own DHCP server or uses a DHCP relay agent to get an address from another subnet.
How do you hook up computer speakers to a 26av502r toshiba?
Question might be old, but I did the exact same thing. The computer speakers usually have an input for a wire that connects to the pc. U can however, buy headphones to rca adapter, whichever cost anywhere from six to fifteen dollars depeneding whereby go. It's really really simple. The headphones to rcaline will plug right into the back of the tv (not to mention speakers.) O added a lot of bass to my tv with the computer speakers I usedc its pretty sweet now.

What two methods are used to assign an IP address to a host?
There are two protocols used for IP addressing . These protocols are IP version 4 and IP version 6. Other than these two protocols DNS is also used to map IP addresses to name .
What is polysynchronous type of network communication?
asynchronous circuit that can handle data stream comming in from multiple sources with multiple clock signals (each with different phase) but of same frequency.
What is difference between routing and switching?
- Switching involves moving packets between devices on the same network. *Conversely, routing involves moving packets between different networks.
- Switching is able to determine where a packet should be sent by examining the MAC address within the data link header of the packet (the MAC address is the hardware address of a network adapter).
- A switch maintains a database of MAC addresses and what port they are connected to.(operate at layer 2 of the OSI model).
- Routers, on the other hand, operate at layer 3 of the OSI Model.
- A router is able to determine where to send a packet using the Network ID within the Network layer header. It then uses the routing table to determine the route to the destination host.
What Information is available to mariner from Admiralty routing charts?

An "Open Network" usually pertains to wireless connections and it means the network is not encrypted so anyone can join the network thus its "open".

Discuss allthe network devices used indifferent layer oftheosi model?
Physical layer = Hub, NIC, Repeater.
Data Link Layer = Switch, Bridge.
Network Layer = Router.
What is the difference between file server and terminal server?
File Server hosts data that can be accessed by Users according to the permissions specified. Where as Terminal Server is the machine that enables usage of Machine simultaneously by many users through remote terminal protocols running on Clients.
File Server provides Central Storage where Terminal Server provides ease of Administration in Desktop Support.
Server migration is the process by which data is moved from one server to another server. Let's use a web server for example. When you have a small website, a small server is adequate. However, when your website gets larger and you have more traffic demands, you will need to use a larger server (which is faster and more powerful). The process of moving from the small server to the large server can be called "server migration". Note that it doesn't always have to be from small to large. Often times, you can move from a large server to a smaller server when you no longer need the computing power. This is still called "server migration".
