Computer Hardware Components
A computer can be a very intimidating piece of equipment for someone who is unfamiliar with how one works. So many pieces of equipment, so many buttons and very little instruction on which piece of hardware goes where and why.
Luckily, we’ve put together a glossary illustrating the most popular hardware components of a computer - and the purpose of each piece of equipment.
Keyboard - The keyboard is hooked up to the computer and displays all the letters of the alphabet as well as numbers, grammatical characters and a variety of functions. The keyboard is used to convey controls and functions to the computer.
Mouse - A mouse is a hand-operated device that controls the functionality of a cursor on your computer monitor. It generally has two or three buttons which are used to execute functions on your computer screen.
Monitor - Your computer monitor is a device that displays signals on a computer screen. You can use your monitor to watch DVDs, play games, create documents or surf the web.
Printer - A printer is often hooked up to your computer so you can print a hard copy of your document(s).
Modem - A modem is a component of your computer which converts signals produced by one type of device into a form which is compatible with another. Ex: a computer and a telephone.
Webcam - A webcam is a device hooked up to your computer which allows you to visually communicate with others who also have a webcam installed.
Power Supply - A power supply unit (PSU) is a device which supplies the power to your computer to keep it running.
These are just a few of the hardware components associated with computers. You should also research other devices like computer cases, video cards, computer cables and scanners to become familiar with all of the elements of a computer.
Computer Networking Services
A computer network is the practice of linking two or more computing devices together for the purpose of sharing data. 
Networks are built with a mix of computer hardware and computer software. This interconnected system will share services and interact through a communications link. If data is being sent over the system then the individual computers must follow a set of common communication rules in order for the data to arrive at is correct destination. This is also vital for the systems to properly understand each other otherwise data will not be received. These rules are known as protocols.
So, in order for a computer network to be set up properly four things must be present: two or more systems, something to share (such as data), a communications link or physical pathway, and a set of rules for communication or protocols.
Wireless computer networking uses radio waves and/or microwaves to maintain open communication channels between computers. This version of computer networking is a more modern approach and is an alternative to wired networking. The advantages of wireless computer networking are that this involves mobility and the elimination of a copper or fiber optic cabling running between computers. However, a wireless computer network has the potential to have radio interference due to weather, other wireless devices or obstructions.
If you are unsure what type of computer network you would like you can have a trained professional come to your home, business, or other location and have them recommend what you need depending on what you are using your network for. You should always hire a trained computer specialist when setting up a computer network as there may be complications and it can be very difficult to learn how to set up a computer network by yourself.
Networking Software and Hardware
Networking allows one computer to share information with another. For home office users, this can be a unique advantage. Rather than putting data directly into two computers, you can put it into one computer and then have that computer share the information by using networking software and hardware. Truly, networking software and hardware make life easier and prove to be excellent time saving tools.In order to create a network in your home you will need to purchase the correct hardware if you don’t already have it. You will need, in some cases, a file server, network interface cards, Ethernet cards, local talk connectors, a switch, a router, and/or a bridge. If you are unfamiliar with these products it may serve you well to discuss with the computer hardware distributor, what parts you may or may not require. Further, you might want to hire someone who is knowledgeable to install your network for you.
You might also need to buy networking software. A networking operating system differs from DOS and Windows applications and if your computer does not possess a networking operating system, you may be forced to invest in one. There are two primary network operating systems:- client/server and peer-to-peer networks. If you are looking to establish a small, but simple networking system then you will most likely benefit from a peer-to-peer network. For larger systems, however, a client/server is your best option.When you have a peer-to-peer network, you will not require a dedicated server to share information between computers. Conversely, a client/server requires the use of a dedicated server and this can result in additional expenses for you. Plus, a peer-to-peer network can adapt easily to a Windows Operating System and a knowledgeable individual can easily configure your existing computer to work with your peer-to-peer software.
Before you decide to set up a networking system, you should most definitely research the process. Networking can be a complicated business and if you are unsure of what you are doing, you can actually damage your existing equipment. Again, if you want a networking system established and you are unsure of how to go about it, your best bet is to spend the extra cash to hire someone who can get the process working for you properly as well as advise you about what options are available.
Ultimately, setting up a home network is meant to make your work easier, not harder. Therefore, when considering your network options, do your research, price comparisons and definitely talk to a professional about the best way to set up your system. Once your home networking system is established you will find that you can share information between computers with ease. In the end, that is your goal - to make your work easier, and you don’t need more complications than those that already arise on a regular basis!
