Introduction to Networking

What is the difference between a router and a switch?

• resources can be shared on a router, only one computer can be active on a router.

• o computer has more authority than another; each computer controls its own resources, and communicates directly with other computers

• A Switch belongs only to a local area network and a router to two or more local area networks

• as the network grows larger, adding or changing significant elements of the network may be difficult.

 What does the term firmware mean?

• Programs embedded into hardware devices.

• The process of adding a header to data inherited from the layer above.

• A Network layer service that subdivides packets into smaller packets when those packets exceed the maximum size for the network.

• An area at the beginning of a payload where protocols add control information.

 Describe the advantages of using networks relative to stand-alone computers.

• Sharing devices such as printers saves money.

  Data is easy to backup as all the data is stored on the file server.

• Purchasing the network cabling and file servers can be expensive.

  Managing a large network is complicated.

• Viruses can spread to other computers throughout a computer network.

• There is a danger of hacking, particularly with wide area networks.

describes how the parts of a whole work together.

• Physical topology

• Topology

• NOSes(Network Operating System).

• Peer to Peet network

network’s hardware and how computers, other devices, and cables fit together

• Logical Topology

• Topology

• Peer to Peer

• Physical topology

Has to do with software and how access to the network is controlled, including how users and programs initially gain access to the network and how specific resources, such as applications and databases, are shared on the network.

• Logical topology

• Physical topology

• Client-server network

• Topology

A network in which every computer can communicate directly with every other computer.

• Client-server

• Peer to Peer

• Remote desktop

• Local area networn(LAN)

A network where resources are managed by the NOS via a centralized directory database.

• Wide Area Network(WAN)

• Peer-to-peer

• Client network

• Locan Area Network(LAN)

A Windows domain uses the client-server model to control access to the network, where security on each computer or device is controlled by a centralized database on a domain controller

• True

• False

In the context of Windows Server NOSes, a group of users, servers, and other resources that share account and security policies, this logical group is called a Windows domain.

• True

• False
