There are different types of network. This introductory article gives a brief overview of the different types of networks out there.
A network topology is like a framework, although purely in virtual terms. A topology is a layout of how computers should connect, not how they are physically arranged in a space.
Packet switching is the method used to relay data over long distances (utilizing the protocols such as Frame Relay, IP and X.25).
Protocols are a lot like a set of rules. For instance, for networking, protocols are used for packet switching the data by dividing the information into ‘packets’ and sending it
over different links
Routers are much different than hubs or switches; they are more complicated network devices capable of handling more complex tasks. At time routers can even integrate the functions of hubs and switches.

First of all there are routers which are hardware equipment used for connecting many wired/wireless networks to each other. It is a layer 3 gateway; hence it works at the network level of the OSI model.
Whereas wireless networking is the newest leap in technology, many networks still remain wired, mainly due to the speed and security of wired connectivity.
Network adapters allow devices to communicate within a network and are a necessary part of a network. There are different types of adapters such as PCI adapters.
Modems (modulator demodulators) are small box like devices used in dial up network connections. Modems translate data from binary to analog and vice versa. Standard model modems handle data at 56000 bits per second (56 kbps), but this speed usually slows down to 33kbps.
A lag switch is a device which is used to create time lags or delays into the flow of data traffic. This way the modem does not get overloaded. Lag switches are often used for the less noble purpose of cheating in online games.
A lot like a network adapter, an Ethernet card supports the standard for a high speed wired connection. They are also known as network interface cards (NICs).
Cat 5 is the fifth generation of twisted pair Ethernet cabling, and the most popular one these days. Made up of four copper wires, it is limited to a length of 100 meters. Usually it only requires two of the copper wires to connect to faster speeds.
These cables are used usually when you wish to connect two similar type devices through Ethernet. They are also used for a short period of time whilst networking devices without a router or its equivalent.

As the name implies, gigabit Ethernet is a more advanced level of Ethernet networking and communication standards, gigabit supports a transmission rate of up to 1gbps
Hertz is a measurement of the transmission frequency of radio signals in a second. Named after the scientist Hein rich hertz, a single MHz (megahertz) is equivalent to a million cycles/sec
Auto sensing is the ability of Ethernet equipment (hubs, switches, NICs) to choose the speeds at which to operate. Auto sensing employs signaling methods to probe the network and find compatible Ethernet speeds. This technique was invented in order to facilitate the conversion from traditional to fast Ethernet equipment.
Wireless spread spectrum communication is employed in cellular networks and Wi-Fi. It provides stability by reducing wireless interference and increased bandwidth by taking advantage of additional wireless spectrum in order to share bandwidth of other channels. Also it provides increased security and keeps out intruders.
A Wi-Fi hotspot is a wireless access point which provides internet access to network devices in public places. Wi-Fi technology is used by home networks as well as those in schools and businesses. Computers connect to Wi-Fi hotspots through network adapters. Some laptops have this inbuilt facility, but those that don’t have it can always purchase it, there are many kind available from PC cards to USBs.
