A local area network (LAN) is a computer network that connects computers in an area with limited space such as a home, school, computer laboratory, or office building, using network media.
A Wide Area Network, or WAN, is made up of many computer networks connected together, often over the Internet. In most cases, the networks in WANs all belong to the same company or school.
A Metropolitan area network, or MAN for short, is a computer network that connects multiple other Local area networks (LANs). An example of where MANs are used, are the networks on a campus of a university. MANs use different technologies than LANs.
The 5-4-3 rule, also known as the IEEE way, is a design guideline for computer networks using Ethernet, covering the number of repeaters and segments on shared-access Ethernet backbones in a tree topology.
Depending on the protocols they need to support, packets tend to be constructed in the standard packet format. Packet formats generally include a header, the body containing the message data, also known as the payload, and sometimes a footer which is also known as the trailer. The packet header shows the destination of the packet and often shows the length of the data in the message. The packet footer contains data that implies the end of the packet, such as a special sequence of bits known as a magic number. The packet header and the packet footer may contain error-checking information.
A DNS lookup, in a general sense, is the process in which a DNS record
WAN(Wide Area Network)-Wan is 2 or more local area networks connected together.It is fairly expensive to set up but like the LAN it is very fast.There are many different ways of creating WANS”S like using VPN’s over the internet.A WAN is created when the users of a LAN frequently needs access to rescources of another
2. What is the difference between a WAN and a LAN? Which type of network is the Internet? Which type of network is the classroom network?
A LAN is a ‘Local Area Network’. It is a small network of computers most often
Module 1 establishes the framework of networking standards and protocols for the rest of the class. The module introduces data communications and defines their components and the types of data exchanged. You will learn how different types of data are represented and how data is flowed through the network.
A Wide Area Network ( WAN) is a computer network covering multiple distance areas, which may spread across the entire world. WANs often connect
LAN stands for Local Area Network. LAN is a type of network that interconnects computers and devices either wired or wireless and covers a greater distance. LAN is mainly used in private organisations such as college or university. More or less everyone uses wireless router at home these days and the user is able to connect between 5-10 devices wirelessly. The user can share the broadband or the connection with ADSL by using Ethernet cables. Smaller LANs can connect at least
LANs standards and protocols are Ethernet, IEEE 802.2 [IEEE 802.3, 100BaseT, Token Ring/IEEE 802.5 and FDDI.
Packets also known as frames are grouped amounts of data that are sent across a network. However, packets differ from frames in that a packet contains that data to be sent, including the source and destination Internet Protocol (IP) addresses. A frame is packet that contains the data, the source and destination IP addresses, Media Access Control (MAC) source and destination addresses, and error checking. The MAC addresses are added at the beginning of the data also known as a header. An error checking code is also added to the end of the data which is referred to as a trailer. After the packet has been “framed”, the frame is then sent over the networking medium (i.e. Ethernet cable).
16. Witch of the following statements is true comparing LANs and WANs? LANs generally connect devices that are nearer to each other, compared to WANs. WANs are purchased, and LANs are leased.
NDAS definitely needs a WAN because of its widespread operations as shown in the text. It also needs LANs in the various offices and departments. These LANs would eventually be interconnected to each other and with the WAN.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking
A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.
Local area networks (LANs). DEFINITION The concept of local area networks (LANs) is not new. It represents a logical development of computer technology. With the advent of microcomputers in the 1980s many office workers began bringing their own disks into work, compromising data integrity.
In order to know and apply the ideas during this chapter, you must be acquainted with basic networking ideas. This includes the functions and options of the TCP/IP protocol suite, technologies like the variants of LAN, synchronous optical network (SONET), and wave division multiplexing (WDM), and therefore the basics of network routing, security, performance, and management.
