Tutorials Web is offering free tutorials on the following which may be useful in Server+ preparation:
        Internet Protocol Version 6 (IPv6) is the next generation protocol for Internet Networking defined by IETF (Internet Engineering Task Force) which is often treated as successor to Internet Protocol Version 4 (IPv4).
 The OSI model defines internetworking in terms of a vertical stack of seven layers. The upper layers of the OSI model represent software that implements network services like encryption and connection management. The lower layers of the OSI model implement more primitive, hardware-oriented functions like routing, addressing, and flow control.
Cisco has wide variety of router types starting from a low end fixed configuration models to that of high-end carrier class routers.
  1. The fixed configuration routers include 850, 870, and 1800(fixed) routers.
  2. The modular class routers include 1800(Modular), 2800, and 3800.
  3. Cisco Access Routers include Cisco SOHO, SB 100, 820/830, 1700, 2600, and 3700 Series;

Computer network planning consists of the following steps:
1. Identifying the applications that you intend to use: Computer networking may be required diverse environments such as Enterprise Resource Management (ERM), Internet telephony, Instant Messaging (IM), eMail and others. It is important to discuss the applications that you intend to use such as the above. These in turn are used for estimating the software, hardware, and traffic requirements.
2. Traffic Requirements: Computing traffic requirements include several factors. A few points to consider include the following:
  1. Identification and documentation of major traffic sources.
  2. Categorization of traffic as local, distributed, client/server, peer-to-peer, terminal/host or server/server.
  3. Estimation of bandwidth requirements for each application.
  4. Quality of Service (QoS) requirements for each application
  5. Reliability requirements.
