This chapter was a good starting point it discussed and provided suggestions for finding a job in networking field. A few ideas discussed were to search the Web, visit a career center, and network with like-minded professionals. These were only a few of the many suggestions covered. It went on to talk about pursuing a certification and the benefits from doing so, such as better salary, greater opportunities, access to better support, and professional respect.
The lesson began with covering networks. It touched on how networks are used and the various services i.e. file and print, access, communications, internet, and management. Each one plays a different role in “network services”. The two fundamental network models are client/server and peer to peer. The following are the advantages and disadvantages of a peer to peer network.
- Simple to configure.
- Often less expensive to start up and maintain.
Disadvantage:
- Not very flexible.
- Not necessarily secure
- Not particle for connecting more than a handful of computers.
The other type of network is the client/server which has a central computer known as a server, to facilitate communications and resource sharing between other computers on the network. Some of the common elements of a client/server network are:
- Workstation
- Server
- Client
- Nic (network interface card
- Node
- Host
- Nos (network operating system)
- Packet
- Address
- Backbone
- Topology
The book explains these components. It goes to review how networks are classified by size. Very simply they are LAN (local area network), MAN (metropolitan area network), and Wan (wide area network).
I found this chapter to be a good foundation in understanding network principles. It provided many diagrams with good descriptions.
