Layer 3 Switches • The Layer 3 switch functions at the Network layer and performs the multiport virtual LAN data pipelining functions of a standard Layer 2 switch It can also perform basic routing functions between virtual LANs Layer 3 Switch
Network Classification Based on Geographic Proximity Local Area Network (LAN) The first kind of network based on geography is the Local Area Network or LAN Local area network resides within a small geographic area An example of a local area network would be the network inside a particular company or the network at our home It can have
Different Types of Networks •Depending upon the geographical area covered by a network it is classified as: –Local Area Network (LAN) –Metropolitan Area Network (MAN) –Wide Area Network (WAN) –Personal Area Network (PAN) •
2-3 LAYERS IN THE OSI MODEL In this section we briefly describe the functions of each layer in the OSI model Physical Layer Data Link Layer Network Layer Transport Layer Session Layer Presentation Layer Application Layer Topics discussed in this section:
Three types of bridges are used in networks: Transparent bridge—Derives its name from the fact that the deviceson the network are unaware of its existence A transparent bridge doesnothing except block or forward data based on the MAC address Source route bridge—Used in Token Ring networks
When your laptop or mobile phone is connected into your home or office network, you’re using what’s known as the local area network (LAN). A LAN is a proprietary computer network that enables designated users to have exclusive access to the same system connection at a common location, always within an area of less than a mile and most often within ...
A personal area network (PAN) is a short-range network topology designed for peripheral devices (usually 30ft) used by an individual. The purpose of these types of networks is to transmit data between devices without being necessarily connected to the internet. PANs can also be connected to LAN and higher level network types where one device acts a...
Wireless technologies have been a major breakthrough in commercial and personal connectivity, opening up numerous possibilities ranging from mobile wireless, fixed wireless, portable wireless, or IR wireless. Connected devices on these configurations communicate over what’s known as a wireless local area network (WLAN). WLANs use high-frequency sig...
Private lines, virtual private networks (VPNs), multiprotocol label switching (MPLS), wireless networks, cellular networks, and the internet allow LANs and other types of networks in different geographical regions to communicate and transmit data. This type of computer networking is known as a wide area network (WAN), a telecommunication network th...
In today’s world of computer networking, efficiency and speed are top priorities. Some technologies manage to deliver both, while others have only one feature or none at all. A metropolitan area network (MAN) ticks both boxes by using technologies such as fiber optics, dense wavelength division multiplexing, and optical packet switching. Typical la...
With a campus area network (CAN), universities, colleges, and corporate campuses connect different LANs from various departments sharing a common area. This transforms otherwise scattered networks into a collective network that provides access to information at breathtaking speeds while ensuring the necessary authentication to prevent privacy looph...
With cyberattacks lurking in every click and the risk of having sensitive information mined, intercepted, or even stolen, a virtual private network (VPN) offers users an encrypted connection that effectively hides data packets while using the internet. This is achieved with a VPN tunnelthat’s created between two communicating devices, encapsulating...
Bandwidth-intensive applications use a huge chunk of company network resources, slowing down data transfer and leading to bottlenecks in business operations. An enterprise private network (EPN) is a custom-design network, built and operated by a business to share company resources. It connects a company’s offices across different geographic regions...
Network storage is synonymous with business continuity in an increasingly competitive world. Businesses that want to stay ahead, need to find ways to optimize data access and data storage, and ensure that important backups are done on a regular basis. One way to achieve these aims and more is by using a storage area network (SAN). A storage area ne...
With the use of coaxial cables, optical fiber cables, or twisted wire pair, different types of network topologies, such as bus, star, and branching tree are used to fulfill specific goals. Information sharing and communication between devices over different topologies is possible with Wi-Fi or TCP/IP Ethernet.
On IPX networks, the NetWareLink State Protocol (NLSP) is used. Table 3.1 summarizes the distance vec-tor and link state protocols used with each network protocol. It is necessary to know which distance vector and link state routing protocols areassociated with which network protocols.
Some examples of devices that operate in the 2.4 GHz band over a WLAN include Bluetooth devices, cordless telephones, Wi-Fi radios, and garage door openers. If you’re looking to sacrifice some signal strength for better speed in a WLAN, laptops can be connected to the 5 GHz band.
