CONCLUSION REFERENCE 1. 0 INTRODUCTION A information processing system ne twork and communication is definedas a collection of computers and thingummys machine-accessible by communication theory channels that facilitates communications among users and allowsusers to share resources with opposite users. Computer Network A computer network is a system of interconnected computers and peripheral devices.For example, it whitethorn connect computers, printers, scanners and cameras. Using computer hardware and software, these interconnected calculate devices can decease with each other through defined rules of information communications. In a network, computers can exchange and share information and resources. A computer network whitethorn operate on wired connections or tunercommunication connections. When two or more networks are linked or connected and are able to communicate with unrivaled another victimisation suitable hardware and software, it is called an internetwork. Communications Communications is about the transfer of information from a s give the axeer, crosswise a distance, to a receiver.Using electricity, radio waves or light, information and data in the form of codes are transmitted through a physical fair such(prenominal) as wire, argument, or even the atmosphere. Therefore, in order to charter communications possible from computers, across telephones and radios and back to computers and other digital devices again, thither 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. Computer NetworkCommunications 2. 0 MOBILE COMPUTING 2. Definition Mobile computing refers to the use of small and portable computing devices in wireless enabled networks that exit wireless connections to a internet or central important server. These devices include laptops, notebook PCs, tablet PCs, palmtops, personal digital assistant (PDAs) and other hand held devices. A radio-signaling device is installed inside these devices for receiving and transmitting electronic data. Mobile computing has enabled users to remain connected while on the move. High end users can opt for satellite based networking which provides wireless connectivity anywhere in the sphere.However, this technology is costly and testament take many years to cause as affordable as Wi-Fi and WiMax. 2. 2Specification, services, and frequencies of Mobile Computing The latest 4G device fromT- nimble is the Samsung galaxy S4G. This phone works on T-Mobiles HSPA+ 4G network, which uses a different technical standard than Sprint or Verizon radio 4G networks. The SamsungGalaxy S 4Gis the wireless carriers firstsmartphone that is capable of delivering theoretical peak download speeds of up to 21 Mbps while in one of T-Mobiles 4G coverage areas.In addition to fast speeds, theGalaxy S 4G has a large, 4-inch display, aSamsung 1GHz Cortex A8 Hummingbird processor, and a prei nstalled 16GB microSD memory card. akin other phones inthe Galaxy S line, this phone overly has Samsungs superior AMOLED touchscreen display. 3. 0 INTERNET TECHNOLOGY AND SERVICES 3. 1VoIP VoIP (Voice over Internet Protocol) is refered as the transmission of voice traffic over IP-based networks. There are triple ways to connect to a VoIP network which is by using a VoIP telephone, using a normal telephone with a VoIP adapter and using a computer with speakers and microphone. . 2BLOG A blog (web log or weblog) is one of the popular activities on the Internet. Most of these blogs are publicly shared and the autors oft update the content on a regular basis. Blog is normally referred to the text produced by author about his or her thoughts, experiences or interest. The world of blogging is referred as blogosphere. Another new term is the blogonomics, which refers to people using the blogosphere to recall money. The posts to a blog are usually arranged in this order, the well-nigh recent entries will always be on top of the journal. . 0 TYPES of NETWORK 4. 1PAN A Personal Area Network (PAN) is a computer network used for communication among computer devices including PCs, laptops, printers, telephones, digital cameras, mobile phone, painting game consoles and personal digital assistants, close to one person. PAN may be wired with USB port, Firewire port, Infrared(IrDA) and Bluetooth technologies. Bluetooth is the popular wireless PAN used by most people, especially the mobile phone technologies, and it applies the IEEE 802. 15. 1 standards. 4. 2VPNA Virtual orphic Network (VPN) is a network that uses a public telecommunication infrastructure, such as the internet, to remote offices or individuals with secure access to their organisations private network. VPN uses tunnelling mechanism to maintain privacy and security of the data. Tunnelling means transmiting data packets across a public network. VPN is often used by companies to provide access from their int ernal network resources to their home or mobile workers. 4. 3WLAN Wireless Local Area Network (WLAN) is a type of LAN that uses high-frequency radio waves to communicate between nodes.WLAN improves user mobility, speed and scalability to move around deep down a broad coverage area and still be connected to the network. The IEEE standard for Wireless Lans is 802. 11. 4. 4WIMAX Worlwide Interoperability for Microwave Access (WiMAX) is the industry term for broadband wireless access network that is developed based on the IEEE 802. 16 standard. WiMAX is a Wireless Metropolitan Area Network (MAN) technology that will connect WiFi hotspots to the Internet and provides a wireless extension to cable and DSL for larger broadband access.WiMAX would operate similar to WiFi save at higher speeds, over greater distances and for a greater number of users. A WiMAX system will have two major move * A WiMAX base station, similar in concept to a mobile phone tower. * A WiMAX receiver installed at home. 5. 0 CONCLUSION As a brief conclusion, computer network and communication are expanding speedily each and everyday making sharing of information trilion times pause before they exist. Mobile computing is now getting edgier by the day. red-hot technologies are being implemented, tested and apply in mobile computing making us and the future another step closer.The internet is also getting better along the lines of the information age. Meanwhile, types of network available for us adding it on top of making computer networks and communications the new top hat friend.
