3.4 DATA LINKS: Definition: A process of sharing data and resources between two or more connected computers. Resources needed: (fax modem / printer / hard disk / Cd or DVD Rom / database / data files) Devices used in data links: Mainframe computers, terminals, personal computers (desktop), laptop computers, voice recognition devices, screens and printers.
3.4 DATA LINKS( Two ways of connecting computers) Telecommunication Networks: Link computers together using special coaxial cable / wireless radio-like signal within an office/ office building complex. Each connected computer to the network can communicate with any computer on the network. This allows for sharing of files and printers and using intra-office electronic mail. A server is set up to provide storage for important data files and program. The server provides access to resources whenever a user on the network needs them. Establish the link between telecommunication systems. The software determines what happens to the data. You connect computers via telephone lines or cell phone wireless connection with a modem. The person can link up with a specific destination by using the computer keyboard, and data transfer can then take place. The host computer receives and saves calls from other computers Remote computers access the host computer.
3.4.2 MODEMS: DEFINITION: TYPES: stands for modulator demodulator Makes communication possible between 2 or more computers via a telephone line. Internal modems: Inserted into the computer in an expansion slot or built into the system. It does not require a cable to connect it to the computer, but must be connected to a telephone line. PURPOSE: Converts data into a signal that can be sent over telephone lines. Another modem receives information sent and coverts it back into data that the computer can understand. A standard modem contains 2 functional parts. An analogue section for generating signals and operating the phone. Digital section for setup and control. E-mails and faxes can be sent via a modem. Data can be transferred through the modem from one computer user to another in a remote area. External modems: Connects to the computer with a cable. Modern performance is measured in the number of bits of data that can be transmitted per second, called the band rate. The band rate can be measured in terms of bits of data per second. A broadband connection is a fast connection cable of transmitting video, audio and graphics.
3.4.2 MODEMS: Types Broadband technology: New technologies: DSL (Digital Subscriber Line): In small businesses connections may be over the telephone line. ADSL modems: Are not limited to telephone voice band audio frequencies. Cable modems: Use a range of frequencies to carry RF television channels. Multiple cable modems: To be attached to a single cable can use the same frequency band, using a low-level media access protocol to allow them to work together within the same channel. Connect card/ PC -or express card: which slides into a PC card/express card slot on the computer. A cellular router can have an external data card (AirCard) that slides into it. Cellular router: allows multiple people to connect to it, because it can route/support multipoint to multipoint connections Wireless modems / cellular modems: use a mobile telephone system . Made for a single connection. Wireless modems can be embedded inside a laptop or appliance or external to use. Almost all modern modems can incorporate with fax machines. Software running on the host computer can convert any image into fax-format, which can then be sent using the modem. Double way satellite and power line modems.
3.4 DATA LINKS: 3.4.3 Channels: DEFINITION: A medium through which impulses are transmitted. Mediums / channels used for communicating data: 1. E.g. Telephone cable/line: Nowadays microwave and satellite channels are also being used. Telephone cable lines are being replaced by Telkom with fibre optic cables because of cable theft.

3.6 COMPUTER NETWORKING DEFINITION: When the computers of a company within a single office or office building are linked together. 1. PURPOSE: Requires 2 main components: special network hardware and network software. Together they are known as a Local Area Network (LAN). Networks are useful for sharing data, storing large amounts of information and sharing expensive equipment such as printers. Can run multiuser programs such as database and order-entry and accounting systems. Each worker in the office using a computer connected to the network can add or retrieve information or share resources such as printers or hard drives.
3.6 COMPUTER NETWORKING Topology: (Set up of a network) Typologies are named for their information e.g. Ring, star, bus RING: computers and devices are set in a closed loop. STAR: computers and devices are connected to a central computer like spokes to a wheel. BUS: connects the devices in a line with additions installed ate one end. PEER-TO-PEER NETWORK: Linking only 2 computers, sharing a printer or disk drive With a central dedicated computer with a large-capacity disk drive to which all the computers are connected, the central computer is the server, the other remote computers are called nodes.
3.6 Computer networks ADVANTAGES of networking: When employees share hardware, the organisation need to buy expensive devices for each user. Sharing software allows everyone using it to perform tasks in the same way. Sharing software allows multiple users to work on projects together. When working as groups, large projects can be completed in time. Using e-mail software allows users to coordinate schedules.
3.6 Computer Networks: TYPES: LAN(Local Area Network): Limited to a relative small geographical are like a room, building, school network, ship, aircraft, small office Known as single location network. Large LANs are divided into smaller workgroups. CAN(Campus Area Network): connects 2 or small LANs. Limited to a specific geographical area like schools, colleges, Confined to an area smaller than a Metropolitan area network. MAN(Metropolitan Area Network): Connects 2 or more LANs and CANs within a geographical area in a town, city or metropolitan area. A number of communication devices are required to create a MAN like routers, switches, hubs, modems WAN(Wide Area Network): Data communication network that covers a very large geographical area. Can be privately owned like multi-national company network Can be publicly owned like the internet. Other types of communication devices like bank and post office networks are also connected on a WAN. Consist of 2 or more computers physically placed at different locations and may also include connections to dumb terminals and other connecting devices.
3.7 TELECONFERENCING SERVICES: DEFINITION: This is a conference conducted over the telephone among people in different geographical locations. AUTOMATED TELECONFERENCING: (also advantages) This telephone service is a quick effective way to have discussions with customers, suppliers or staff members. Popular with businesses that have branches all over the country or internationally. Enables people to hold relatively inexpensive meetings on short notice, which can speed up decision-making. Bear in mind that people cannot see each other and cannot read your body language. Its important to articulate everything and not just nod your head if you agree. Up to 7 people can connect to this service at the same time without pre-booking or operator assistance. All participants are billed separately. A more popular version of this is video conferencing where people taking part can also see on a video screen while they speak. SETTING UP AN AUTOMATED TELECONFERENCE: Set a date and time. choose a 5-digit PIN Inform all participants of the conference details and the PIN to be used.
