no...you can buy things like wireless internet cards or drill holes in the wall to hardwire it but having just a wireless thing would be easiest
You will need at least one router with at least 6 lan ports. 5 for lan (if all computers are using cables to connect) and 1 for wlan (internet cable). 5 LAN cables. Usually default automatic setting enable automatic DHCP server which is responsible for automatic IP addresses. But you have to check in router settings.
Also make sure that you PCs are in the same workgroup (win+Pause->Computer Name->Change). If you have to change the workgroup name you will have to restart your PC(s) after that.
After that press Start->Run. In run print "cmd". In cmd ping 192.168.1.1 (if you work in 192.168.1.xxx subnet) and 192.168.1.2. It will check connection with itself and with another PC.
What are the differences between LAN and WAN?
LAN means Local Area Network, as the name implies its used for local areas such as in your home or office for sharing data, informations or play games etc.. and WAN means Wide Area Network, which is used for wide or broad areas to share data or get informations such as across a country. But to transfer data globally, across the world internet is used.
DVR's that have ethernet ports are capable of connecting to the internet. With DirecTV, it is used for On Demand downloads and it is also used to access media on all of your PC's that are connected to the same network as the DVR unit. With TiVO units, you can actually go to YouTube and play media from that site.
1. Convert 7CA4 to binary
2. Locate bits 8 and 9.
3. Write out all possible combinations of the address changing those 2 bits.
4. Convert back to hex to get the answer.
What is divided in TDM multiplexing technique?
TDM means time domain multiplexing. One communication channel transmits for a short time, then another, then another. For example, in modern cell phones, up to 8 users share a frequency; each transmits for a few milliseconds at a time.

What level of the OSI creates packets?
Some textbooks say that the packet is fully created when it reaches the physical layer, although the actual final construction is layer 2 (Data link layer).
Then again, some textbooks will say that the packet is fully created in layer 2 and is transmitted out the physical layer as a frame.

What is switchport mode configuration?
Switchport mode allows for the configuration of a port into certain settings. A few examples are Access, Trunk, and Dynamic. Each mode allows for different functions. Access mode is used for end devices, this allows for certain port security settings. Trunk mode is used for lines between switches and other lines that send multiple VLANs over a single connection. Dynamic will automatically detect what kind of device is connected and initiate its port accordingly.
To which network device or interface does the IP address 192.168.1.254 belong?
That is normally the IP address of a router
What is the purpose of a port in data communication?
How do we know what application to send the data to? Say you have 2 Google tabs open and you search 2 different things at the same time. How does the computer not switch the information between the two tabs? Why is it always the right information? Because of ports. Ports uniquely identify different applications or processes running on a single computer allowing different applications to share a single internet connection.
Your computer created 2 separate ports for the Google searches, thereby distinguishing them.
What are the two characteristics of OSPF?
The first is that the protocol is open, which means that its specification is in the public domain. The OSPF specification is published as Request For Comments (RFC) 1247. The second principal characteristic is that OSPF is based on the SPF algorithm, which sometimes is referred to as the Dijkstra algorithm (Answer is from CCNA 3 guide)
What ip address will a belkin router use?
i have one now, and it uses 192.168.1.1, but they can differ slighty depending if it has been changed in the past.
What is computer network about?
Computer Network is all about sharing Information & Resources amongst Users & Devices within network.
Computer Networks enables efficient usage of Resources (Such as printers, scanners etc) so that multiple devices for same functionality aren't required at every user's place.
Computer Networks can provide Central Stored information & makes them available to all permitted Network users or devices.
Choose this option if you want the server to respond only to known clients that have been prestaged. Prestaging a computer requires that an administrator create a managed computer account in Active Directory before booting the client so that it can be installed over the network.
Which tcp ip architecture makes use of ports?

In this chapter, we will take a look at the TCP/IP protocol stack to help us better understand how TCP/IP functions in the network. We'll look at the Department Of Defense (DoD) protocol layers and the Open Systems Interconnect (OSI) model to help us better understand how protocols and utilities function at various layers. We'll discuss the protocols that comprise the TCP/IP suite of protocols and look at some TCP/IP configuration and troubleshooting information.
At the end of this chapter, you will be able to:
· Discuss the protocols that support the Internet.
· List the layers in the OSI and DoD networking models.
· Describe the TCP/IP suite of protocols.
TCP/IP made early WANS possible. TCP/IP's robust set of protocols provided complete networking support to connect all hosts and sites and rapidly became the standard for such activities. Over time, the TCP/IP suite of protocols and utilities has become much more than just a standard-it has helped us usher in a new era of computing. We can now configure machines around the world and monitor events on distant computers. Although local area networking standards remained in the realm of proprietary vendor standards until the mid 1980's, they have changed so much since then that today there is nearly total interoperability in the TCP/IP world. With TCP/IP, we can connect to the world. Before we do that, however, let's look closer at what the protocol suite is capable of doing
Abstract
This chapter examines the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite in greater detail, analyzing its four layers and the core protocols used within each layer. Network administrators must have an understanding of the core protocols in the various layers and their functions to understand how networking applications work, how data is sent from one application to another, and how to interpret network captures. This chapter also discusses the two main application programming interfaces (APIs) that networking applications for the Microsoft® Windows® operating systems use and the APIs' naming schemes.

What is gateway networking for companies?
Gateway networking is a default gateway device that allows multiple traffic to be combined and transferred with the use of a particular hardware. Many companies use this for their business to help keep their connection secure and up to speed.
What can a content server be used for?
A content server is used for Document Management Systems (DMS) to store and retrieve documents. They can be attached to ECC programs and process PR programs.
A query is sometimes called a logical view of data because?
Queries do not store Is_A_query_datasheet_is_called_a_logical_view_of_the_data_because_a_query_does_not_physically_store_the_data_as_it_is_still_stored_in_the_tables, they only display a view of data.
What is cooperative transmission in wireless sensor network?
In an ordinary wireless network there are hubs set up specifically for connecting the wireless devices to the larger (wired) network. In a cooperative network, a device that can't reach a hub might talk to another device that can, and the second device would pass along the network traffic.
It's similar to one cell phone that can't reach a cell tower talking directly to another cell phone and letting that other cell phone connect it to the tower. (cell phones don't actually do this)
What does LAN and WAN stands for?
LAN stands for Local Area Network & WAN stands for Wide Area Network.
