A router is specialized computer connected to more than one network running software that allows the router to move data from one network to another. Routersoperate at the network layer (OSI Model's layer3). The primary...
All networks are made up of basic hardware building blocks to interconnect network nodes, such as Network Interface Cards (NICs), Bridges, Hubs, Switches, and Routers. In addition, some method of connecting these building blocks is required, usually in the form of galvanic cable (most commonly Category...
hierarchical, redundant, and secure topology models are covered. Technologies like Ethernet, Fast Ethernet, FDDI, and Token Ring are also covered in this chapter. This chapter also discusses the characteristics of repeaters, bridges, switches, and routers, as well as how to apply these devices in a LAN...

What is a NIC?
A Network Interface Card (NIC), also called a Network Adapter, is used to connect a computer to the cabling used in a local area network (LAN). Typically, the NIC attaches to the computer’s expansion bus via an ISA slot (8-bit or 16-bit) or a PCI slot (32-bit)...

What is meant by Router ?
What is the Difference between HUB and SWITCH ?
A router is an electronic device that interconnects two or
more computer networks, and selectively interchanges
packets of data between them . A router is a networking
device whose software...
Repeaters are used to boost signals in coaxial and twisted pair cable and in optical fiber lines. An electrical signal in a cable gets weaker the further it travels, due to energy dissipated in conductor resistance and dielectric losses. Similarly a light signal traveling through an optical fiber suffers...

For the first section of this Mid Term, I will describe the fields in the IP version 4 (IPv4) packet header. (What is the structure (each field) of an IPv4 packet?). The first field is a 4-bit version field. Next we have a 4-bit Internet Header Length (IHL) that tells the number of 32-bit words in...
IEEE 802 utilizes various standards and mediums that enable communication between devices. Frequently deployed devices include hubs, switches, bridges, or routers. Wireless LAN technology is designed to connect devices without wiring. These devices use radio waves or infrared signals as a transmission medium...

What is a computer Network?
A network is any collection of independent computers that communicate with one another over a shared network medium. A computer network is a collection of two or more connected computers. When these computers are joined in a network, people can share files and peripherals...
