Course Syllabus

Welcome to the Networking course of the IT Support Professional Certificate! In the first week of this course, we will cover the basics of computer networking. We will learn about the TCP/IP and OSI networking models and how the network layers work together. We'll also cover the basics of networking devices such as cables, hubs and switches, routers, servers and clients. We'll also explore the physical layer and data link layer of our networking model in more detail. By the end of this module, you will know how all the different layers of the network model fit together to create a network.

Course Introduction

The Bits and Bytes of Computer Networking This course, The Bits and Bytes of Computer Networking, covers the key technologies that make computers work together, connecting the myriad pieces of the network together. We'll cover topics such as computer network operations, network protocols, and security and privacy. We'll also cover common challenges in computer networked applications, such as network bandwidth use, privacy concerns, and the like. You'll learn key techniques for monitoring your computer's network operations, like how to troubleshoot your computer's security system, and how to apply key techniques for managing your computer's resources, if you have them. All the while, you'll receive daily video lectures, and other resources, to help you get up to speed on the different components of a computer network. We'll cover topics such as how to get the most out of your computer's resources, how to manage your computer's hardware and software, and the like. You'll also learn how to apply key techniques for monitoring and mitigating against security threats and attacks. And of course, you'll learn how to find security holes in your computer network. This is the second course in the specialization. The first course covered the basic architecture of computers, and covered how computers communicate over a network. We'll learn how the network functions, what protocols and services are provided by the network, and how to identify the components of a networked system. We'll also cover security issues and vulnerabilities in your computer's networking system, as well as how

Bits and Bytes Bits and Bytes was the name of two Canadian educational television series that taught the basics of how to use a personal computer. The first series, made in 1983, starred Luba Goy as the Instructor and Billy Van as the Student. "Bits and Bytes 2" was produced in 1991 and starred Billy Van on his own.
Bits and Bytes The intro sequence featured a montage of common computer terms such as "ERROR", "LOGO" and "ROM", as well as various snippets of simple computer graphics and video effects, accompanied by a theme song that very heavily borrows from the 1978 song Neon Lights by Kraftwerk. The series were produced by TVOntario. The Writer-Producers of both "Bits and Bytes" and "Bits and Bytes 2" were Denise Boiteau & David Stansfield.

Frame (networking) A frame is a digital data transmission unit in computer networking and telecommunication. A frame typically includes frame synchronization features consisting of a sequence of bits or symbols that indicate to the receiver, the beginning, and end of the payload data within the stream of symbols or bits it receives. If a receiver is connected to the system in the middle of a frame transmission, it ignores the data until it detects a new frame synchronization sequence.
Units of information Historically, a byte was the number of bits used to encode a character of text in the computer, which depended on computer hardware architecture; but today it almost always means eight bits – that is, an octet. A byte can represent 256 (2) distinct values, such as the integers 0 to 255, or -128 to 127. The IEEE 1541-2002 standard specifies "B" (upper case) as the symbol for byte. Bytes, or multiples thereof, are almost always used to specify the sizes of computer files and the capacity of storage units. Most modern computers and peripheral devices are designed to manipulate data in whole bytes or groups of bytes, rather than individual bits.
Peer group (computer networking) In computer networking, a peer group is a group of functional units in the same layer (see e.g. OSI model) of a network, by analogy with peer group. See also peer-to-peer (P2P) networking which is a specific type of networking relying on basically equal end hosts rather than on a hierarchy of devices.
Chief networking officer In computer networking, the chief networking officer is "responsible for network strategy, advanced network product development, and translation to line products of future networking and distributed computing technologies."

Frame (networking) Often, frames of several different sizes are nested inside each other. For example, when using Point-to-Point Protocol (PPP) over asynchronous serial communication, the eight bits of each individual byte are framed by start and stop bits, the payload data bytes in a network packet are framed by the header and footer, and several packets can be framed with frame boundary octets.
Frame (networking) In the OSI model of computer networking, a frame is the protocol data unit at the data link layer. Frames are the result of the final layer of encapsulation before the data is transmitted over the physical layer. A frame is "the unit of transmission in a link layer protocol, and consists of a link layer header followed by a packet." Each frame is separated from the next by an interframe gap. A frame is a series of bits generally composed of framing bits, the packet payload, and a frame check sequence. Examples are Ethernet frames, Point-to-Point Protocol (PPP) frames, Fibre Channel frames, and V.42 modem frames.

Computer industry The computer or information technology, or IT industry is the range of businesses involved in designing computer hardware and computer networking infrastructures, developing computer software, manufacturing computer components, and providing information technology (IT) services.
Computer performance In computer networking, bandwidth is a measurement of bit-rate of available or consumed data communication resources, expressed in bits per second or multiples of it (bit/s, kbit/s, Mbit/s, Gbit/s, etc.).

Computer network Computer communication links that do not support packets, such as traditional point-to-point telecommunication links, simply transmit data as a bit stream. However, most information in computer networks is carried in "packets". A network packet is a formatted unit of data (a list of bits or bytes, usually a few tens of bytes to a few kilobytes long) carried by a packet-switched network.
Sound Bytes The focus of the show is computers, computer users, and the computing industry, and also sometimes covers technology in general and its social and political implications. It is hosted by Nick Francesco, Dave Enright, and Steve Rea. The format of the show also allows computer users to call in to try to get assistance with their computer problems. Unlike many strictly local radio station programs, the Sound Bytes crew allows those who are listening to the show via the Internet to get on the air as well.
History of delay-tolerant networking With the growing interest in mobile ad hoc routing and the increasing complexity of the Interplanetary Internet, the 2000s (decade) brought about a growing number of academic conferences on delay and disruption-tolerant networking. This field saw many optimizations on classic ad hoc and delay-tolerant networking algorithms and began to examine factors such as security, reliability, verifiability, and other areas of research that are well understood in traditional computer networking.
