Do you think wireless networks will totally replace the wired or fixed networks in coming future? Prove validity of your opinion.
Idea Solution:
• Wired Local Area Networks make use of Ethernet cables and network adapters. Numerous computers can be wired to one another by using an Ethernet crossover cable. Wired LANs also need vital devices like hubs, switches, or routers to aid further computers.
• For dial-up connections to the Internet, the computer hosting the modem should administer Internet Connection Sharing or similar software to share the connection with every other computers on the network.
• Broadband routers permit easier sharing of cable modem or DSL Internet connections, furthermore they often include built-in firewall.
• Ethernet cables should proceed from each computer to a different computer or to the central device.
• The accurate cabling configuration for a wired LAN differs depending on the merge of devices, the form of Internet connection.
• Following hardware installation, the lasting steps in configuring either wired or wireless LANs do not contrast a great deal. Equally rely on standard Internet Protocol and network operating system configuration options.
Advantages and Disadvantages of Wired Networking
advantages:
• The equipment is inexpensive.
• Many computers have a wired network adapter.
• Wired networks transfer information more swiftly
• Wired networks are generally more secure than wireless networks
disadvantages:
• Running the wires from each room within the home can be a difficult task.
• Network cables can look disorganized.
• Network cables can disconnect or become faulty consequently causing the connection to fail.
• Adding more computers to a wired network may result in unexpected expense if you run out of connections on your network and could slow down the network.
All wired networks differ from each other. The most familiar type of wired network is an Ethernet network.
Wireless vs. Wired
There are two kinds of network technologies:
• Wireless - communicates through radio waves
• Wired - communicates through data cables (most commonly Ethernet-based)
Why choose a wireless network?
Wireless networks don't use cables for connections, but rather they use radio waves, like cordless phones. The advantage of a wireless network is the mobility and freedom from the restriction of wires or a fixed connection. The benefits of having a wireless network include:
• Mobility and freedom - work anywhere
• No restriction of wires or a fixed connection
• Quick, effortless installation
• No cables to buy
• Save cabling time and hassle
• Easy to expand
Also known as Wi-Fi, or Wireless Fidelity, wireless networks allow you to use your network devices anywhere in an office or home, even out on the patio. You can check your e-mail or surf the Internet on your laptop anywhere in your house. There is no need to drill holes in the wall and install Ethernet cables. You can network anywhere - without wires. Outside your home, wireless networking is available in public "hotspots," such as coffee shops, businesses, hotel rooms, and airports. This is perfect for those of you who do a lot of traveling.
Why choose a wired network?
Wired networks have been around for decades. Wired networking technology found today is known as Ethernet. The data cables, known as Ethernet network cables or wired (CAT5) cables, connect computers and other devices that make up the networks. Wired networks are best when you need to move large amounts of data at high speeds, such as professional-quality multimedia. The benefits of having a wired network include:
• Relatively low cost
• Offers the highest performance possible
• Fast speed - standard Ethernet cable up to 100Mbps.
• Faster speed - Gigabit Ethernet cable up to 1000Mbps
WLAN vs LAN
LAN stands for Local Area Network, which is a collection of computers and other network devices in a certain location that are connected together by switches and/or routers that facilitate the communication of the network elements. Each computer or network element is connected to the switches/routers via a UTP cable. The added letter in WLAN stands for wireless. This is a type of network where the data is not transmitted via cables but over the air through the use of wireless transmitters and receivers.WLANs are deployed in areas where a wide number of computers may connect to the network but not at the same time. Places like coffee shops often add WLAN to their shops to entice more customers who do not stay for extended periods. Even at home where you have a somewhat fixed number of computers that connect to the network, WLAN is also preferred as it gives users the freedom to move around the house and carry their laptops with them without needing to fuss with cables. For areas where the computers are pretty much fixed, a wired LAN is very desirable due to the advantages that it offers.First off, a wired LAN is much faster compared to a WLAN. Most wireless routers nowadays are limited to a theoretical maximum speed of 54mbps while a contemporary wired LAN has a bandwidth of 100mbps. Gigabit network equipment can even ramp this up to 1000mbps or 1Gbps. This might not be such a big issue for browsing the internet or sending email but when you are copying large files, it can take a while with a WLAN.WLANs are also vulnerable to attack as just about anyone with a strong enough transceiver is able to detect the signal. Access can then be achieved by breaking the encryption used by the router through certain software. The information that is being transmitted through the WLAN can also be collected by malicious person and used in a variety, often destructive, ways. In order to intercept data in a wired LAN, you need to physically connect to a switch or a router.Summary:1. LAN refers to a wired network while WLAN is used to refer to a wireless network.2. LAN is commonly used in fixed networks while WLAN is common in areas where computers are moved quite often.3. WLAN is more convenient to users compared to LAN.4. LAN is much faster compared to WLAN.5. LAN is more secure compared to WLAN.
