- 1WHAT IS A HUBHUB IS A DEVICE THAT CONNECTS NODES TOGETHER AND SENDS DATA TO OTHER NODES ACROSS THE SERVER
A - 2WHAT IS A NETWORKAt least two computers (Nodes)
Each having a NIC – network interface card (either wired or wireless) - 3WHAT IS A SWITCHA device that connects nodes together.
An intelligent device that can sends data to the nodes that the data is intended for.
This reduces network traffic because making the network run faster. - 4WHAT DO ROUTERS DORouters work by sending data between networks
- 5WHAT IS A LANA local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building
- 6WHAT IS A WANA wide area network is a telecommunications network or computer network that extends over a large geographical distance. Wide area networks are often established with leased telecommunication circuits
- 7WHAT ARE THE ADVANTAGES OF A COMPUTER NETWORKAdvantages of computer networking. There are several distinct advantages to networking, including: ... Resource sharing – using network-connected peripheral devices like printers, scanners and copiers, or sharing software between multiple users, saves money.
- 8WHAT ARE THE DISADVANTAGES OF A COMPUTER NETWORKPurchasing the network cabling and file servers can be expensive.
Managing a large network is complicated, requires training and a network manager usually needs to be employed.
If the file server breaks down the files on the file server become inaccessible. Email might still work if it is on a separate server. The computers can still be used but are isolated.
Viruses can spread to other computers throughout a computer network.
There is a danger of hacking, particularly with wide area networks. Security procedures are needed to prevent such abuse, eg a firewall. - 9WHATS THE DIFFERANCE BETWEEN A HUB AND A SWITCHEthernet hubs, switches, and routers are all devices that let you connect one or more computers to other computers, networked devices, or even other networks.
- 10WHATS THE INTERNETe Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide
- 11WHATS THE W W WThe World Wide Web is an information space where documents and other web resources are identified by Uniform Resource Locators, interlinked by hypertext links, and can be accessed via the Internet.
- 12WHATS A MODEMA modem converts digital signals generated by the computer into analog signals which can be transmitted over a telephone or cable line and transforms incoming analog signals into their digital equivalents.
- 13What is the purpose of an ISP?An Internet service provider (ISP) is an organization that provides services accessing and using the Internet. Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.
- 14WHATS A BUS TOPOLGYa bus topology is a network setup in which each computer and network device are connected to a single cable or backbone
- 15WHATS A STAR TOPOLOGYA star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch
- 16WHATS A RING TOPOLOGYA ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring
