Network requires each(prenominal) computer to have a network card.Advantages of using networksSharing files You can dole out files between computers through using networks instead of using a flash memory to trip out a file from one computer to another.Sharing resources done networks, people working in a same place can helping printers, scanners, fax machines. This is less make uply for institutions with many computer users.Sharing programs Through networks, People working in the same place can share the same program instead of purchasing individual program for each one.Communication Users on a network can communicate with each other by e-mails even if there is no internet familiarity.Types of networks on that point are three types of network which are topical anesthetic commonwealth Network (local anesthetic area network).Wireless Area Network (WLAN).Wide Area Network (WAN).1. Local Area Network (LAN)A LAN is a system where computers are connected together in spite of appearance a company or organization to enable people share files and resources such as printers. A LAN can be within the same building or within a group of buildings close to each other.2. Wireless Local Area Network (WLAN)Computers are connected together through high absolute frequency radio signals. They are used in many office buildings, burnt umber shops and even at groundworks. No wiring is required between the computers and the peripherals (peripheral device is any device that can attach to the computer such as speakers, printers and scanners).3. Wide Area Network (WAN)Computers are connected together everywhere a wi de area such as between towns or countries. Communication between computers can be done through tele skirt lines, fiber optics and radio touchs or satellites. The internet is an example of it. thickening / server computersA client computer is the computer that needs data from another computer known as a server. The server is a powerful computer than client computer in terms of data storage and processing speed.Activity (4-1)ObjectivesUnderstanding what a network is.Identifying the advantages of using networks.1. Complete the following sentencesNetwork is .........Through networks people can share .., .. and ...The three types of networks are .., .. and ...The computer that requests data from the server is called ..LAN is an abbreviation of .. mend WAN is an abbreviation of ..3. Which type of network is the internet? meshThe internet is a global network of interconnected networks around the orb. The take up thing about the profit is the amount of information that you can access from it. The internet is not the same as World Wide mesh (WWW) as the internet is the network but the World Wide Web is a vast collection of linked documents held on computers all all over the innovation and can be accessed using a web browser.Web browser is software that is used to retrieve and display contents on the World Wide Web, including text, image, boob tube and other types of files.
