1.0 Introduction
Computer Networks.
A computer network is a system of interconnected computers and peripheral devices. For example, it may connect computers, printers, scanners and cameras. Using hardware and software, these interconnected computing devices can communicate with each other through defined rules of data communications. In a network, computers can exchange and share information and resources.
A computer network may operate on wired connections or wireless connections. When two or more networks are linked or connected and are able to communicate with one another using suitable hardware and software, it is called an internetwork.

Communications.
Communications is about the transfer of information from a sender, across a distance, to a receiver. Using electricity, radio waves or light, information and data in the form of codes are transmitted through a physical medium such as wire, cable, or even the atmosphere.
Therefore, in order to make communications possible from computers, across telephones and radios and back to computers and other digital devices again, there must be a signal translator, which we call – a modem. The modem, which is short for modulator or demodulator, converts digital signals into analog and back again into digital signals for information to move across the telephone line.

3.0 Internet Technology and Services

3.1VoIP Protocol use to carry voice signals over the IP network are commonly referred to as voice over TP or VoIP. VoIP is one of the internet technologies that allows a user to make telephone calls using a broadband internet connection instead of a regular for analogs phone line. VoIP is a method for tacking analog audio signal and turning them into digital data that can be trusmited over the internet. * Three difference VoIP services :-
Analog Telephone Adapter , IP phones , Computer to computer. * Analog Telephone Adapter (ATA)
The simplest and most common may through the use of a device. Allows you to connect a standard phone to your computer or your internet connection for use with VoIp. The ATA is on analog to digital converter it takers the analog signal from traditional phone and convert it into digital data for transmission over the internet. Skype, One VoIP provides, Offers free calling locally and between members and inexpensive long-distance calls to other numbers. * Ip phones.
It looks just like normal phone with a convert, a cradle and buttons. IP phones have an RJ-43 external connecter instead of the standard RJ-11 phone connecter. Ip phones connect directly to your router and have all the necessary hardware and software onboard to handle the IP call. Soon, Wifi IP phones will be avaible, allowing, subscribiry callers to make voze calls from any wifi hot spot. * Computer to computer
Computer to computer is certainly the exviest way to use VoIP. Devices needed to piciep a computer to computer internet telephone call. Example Software, microphone, speaker or headphone, sound car, internet connection. * Advantage of VoIP
Offer features and service that are not avaible with a traditional phone. Not need to maintain and pay the additional cost for a line just to make telephone calls. You can talk for as long as you want with any person the world. You can talk with many people at the fame times without any additional card.

* Disadvantage of VoIP
Do not work during powerof failures and services provider may not offer backup power not all VoIP service connect directly to emergency services. VoIP providers may or may not offer directions assistance or white page listings. As VoIP uses an internet connection, if is subceptible to all the problem normally associated eith home broadband services. 3.2 BLOG
A blog is usuallyreterned to the text produced by the author about his/her through, experiences or interest. The world of blogging referred as blogsphere. Another flew term is the blogonomics, which refers to people using the blogosphere to generate money.
To write a good blog, you need to remember there principle :
Use a consistent writing styre and appropriate one top your subject. Post offen, through your post are short. Allow your readers to leave your comments on your posts. Following are several top blogging resources you should check out :

4.0 Types of network.

5.1 PAN(Personal Area Network) Is a computer network used for communication among computerized devices, including telephones and personal digital assistants. PANs can be used for communication among the personal devices themselves (intrapersonal communication), or for connecting to a higher level network and the Internet (an uplink). A wireless personal area network (WPAN) is a PAN carried over wireless network technologies such as IrDA, Wireless USB, Bluetooth, Z-Wave, ZigBee, or even Body Area Network. The reach of a WPAN varies from a few centimeters to a few meters. A PAN may also be carried over wired computer buses such as USB and FireWire. 5.2 VPN ( Virtual Private Network)
VPN used funelling mechanism to maintain pricacy and security of the data. Funelling means transmitting data packets across a public network. VPN is often used by companies to provide access from their internal network resources to their home or mobile workers. 5.3 WLAN (Wireless LAN)
WLAN is a type of LAN that uses high-freequency radio waves to communicate between nodes. WLAN improves user mobility, speed and scalability to move around within a broad coverage area and still be connected to the network. 5.4 WIMAX (Worldwide Interoperability For Microwave Access)
WIMAX is the industry term for broadband wireless access network. WIMAX is a wireless technology that will connect wifi hotspots to the internet and provides a wireless extension to cable and dsl for longer broadband access. WIMAX would operate similar to wifi but at higher speeds over greater distance and for a greater.

5.0 Conclusion
Computer network and communications are very useful for people to communicate each other and help in any field. It would be more easy to communicate with friends or others .
