Read on to get a clearer picture of what you need to optimize your home network. When do you need a switch? What exactly does a router do? Do you need a router if you have a single computer? Network technology can be quite an arcane area of study but armed with the right terms and a general overview of how devices function on your home network you can deploy your network with confidence.

Here is the simplest network configuration available: This user cannot access the internet with a Wi-Fi device thus no access for smart phones, tablets, or other wireless devices and they lose out on the benefits of having a router between their computer and the greater internet.

When should you use a router? Given the low cost of home routers and the benefits gained from installing one on your network you should always use a router which almost always includes a firewall feature.

Home routers are actually a a combination of three networking components: In a commercial setting the three pieces of hardware are kept separate but consumer routers are almost always a combination of both the routing and switching components with a firewall added in for good measure.

At the most basic level a router links two networks together, the network within your home however big or small and the network outside your home in this case, the Internet. The broadband modem provided to you by your ISP is only suited to linking a single computer to the internet and usually does not include any sort of routing or switch functionality.

A router performs the following functions: A router manages those multiple connections and ensures that the right packets of information go to the right places.

Related to the IP sharing function, NAT modifies the headers in packets of information coming into and out of your network so that they get routed to the proper device. Without DHCP you would have to manually configure and add all the hosts to your network.

This means every time a new computer entered the network you would have to manually assign it an address on the network. DHCP does that for you automatically so that when you plug your XBOX into your router, your friend gets on your wireless network, or you add a new computer, an address is assigned with no human interaction required.

Routers act as basic firewalls in a variety of ways including automatically rejecting incoming data that is not part of an ongoing exchange between a computer within your network and the outside world. On the other hand, if a sudden burst of port probing comes in from an unknown address your router acts as a bouncer and rejects the requests, effectively cloaking your computers.

In addition to the inside-to-outside network functionality outlined above, home routers also act as a network switch. A network switch is a piece of hardware that facilitates communication between computers on an internal network. Without the switching function the devices could talk through the router to the greater internet but not to each other—something as simple as copying an MP3 from your laptop to your desktop over the network would be impossible.Computers store data and the instructions as numbers, because computers can do things with numbers very quickly.

These data are stored as binary symbols (1s and 0s).

A 1 or a 0 symbol stored by a computer is called a bit, which comes from the words binary digit. Understanding what each individual hardware component in your computer does will help you to work out which part (or parts) are causing the issues, and then you can look at .

The information for the web page you are looking at is recorded on a hard disk inside a computer located in New Britain, Connecticut. The hardware components of a computer system are the electronic and mechanical parts. The software components of a computer system are . Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed.
