This book covers the most important Internet applications and the methods u=
sed to develop them, the network edge and core, reliable transport and netw=
ork congestion management, malware and security systems, emerging technolog=
ies such as virtualization and cloud computing, and more. It also uses a we=
alth of examples and illustrations to explain complicated concepts simply a=
nd clearly.

In this article, we will give you an overview of the book's main topics, fe=
atures, and benefits. We will also show you how to download the epub versio=
n of the book for free.

What You Will Learn from This Book
This book is divided into six parts, each covering a different aspect of co=
mputer networks and cybersecurity. Here is a brief summary of what you will=
 learn from each part:




Part 1: Internet Applications. This part introduces you to the most common =
Internet applications, such as web browsing, email, file transfer, remote l=
ogin, voice over IP, streaming video, peer-to-peer networking, social netwo=
rking, and online gaming. You will also learn how to develop your own Inter=
net applications using sockets, HTTP, SMTP, FTP, Telnet, DNS, SIP, RTP, RTC=
P, BitTorrent, PNRP, Skype, Facebook API, and HTML5.
Part 2: Network Edge. This part discusses the network edge, which consists =
of hosts (such as computers, smartphones, tablets), access networks (such a=
s DSL, cable modem, wireless LAN), local area networks (LANs), and physical=
 media (such as twisted pair, coaxial cable, fiber optic). You will learn h=
ow hosts communicate with each other using Ethernet, wireless LAN protocols=
 (such as 802.11), Bluetooth, cellular networks (such as 3G/4G/5G), WiMAX, =
satellite networks, RFID tags, NFC devices.
Part 3: Network Core. This part explores the network core, which consists o=
f packet switches (such as routers), circuit switches (such as telephone sw=
itches), and the Internet backbone (such as Tier-1 ISPs). You will learn ho=
w packets are forwarded through the network using routing protocols (such a=
s RIP, OSPF, BGP), switching techniques (such as store-and-forward switchin=
g, cut-through switching), multicast routing (such as IGMP), quality of ser=
vice mechanisms (such as IntServ/DiffServ), network address translation (NA=
T), IPv6 transition technologies (such as ISATAP/Teredo).
Part 4: Reliable Transport. This part examines reliable transport protocols=
 that ensure reliable data delivery between hosts over unreliable networks.=
 You will learn how TCP provides reliable transport using connection establ=
ishment/termination,
flow control/congestion control/error control/windowing mechanisms,
segment structure/header fields/options/flags,
TCP variants/improvements (such as Tahoe/Reno/New Reno/SACK/Cubic),
and TCP performance analysis. You will also learn how UDP provides unreliab=
le transport for real-time applications such as voice/video streaming.
Part 5: Cybersecurity. This part delves into cybersecurity mechanisms that =
protect networks and applications from cyber attacks. You will learn about =
the types of malware (such as viruses/worms/Trojans/rootkits/botnets/ransom=
ware) and the security systems that detect/prevent/mitigate them (such as a=
ntivirus software/firewalls/intrusion detection systems/intrusion preventio=
n systems). You will also learn about cryptography (such as symmetric/asymm=
etric encryption/hash functions/digital signatures/public key infrastructur=
e/certificates) and its applications in network security (such as SSL/TLS/H=
TTPS/IPsec/VPN).
Part 6: Emerging Technologies. This part looks at emerging technologies tha=
t are changing the landscape of computer networks and cybersecurity. You wi=
ll learn about virtualization (such as hypervisors/virtual machines/contain=
ers/Docker/Kubernetes) and its benefits for network management/scalability/=
security/isolation. You will also learn about data center and cloud
