Internet Routing and Structure
Border Gateway Protocol, autonomous systems, peering and exchange points.
The internet's global structure is a set of independently operated networks that agree how to reach one another. One protocol carries those agreements, and the physical places where networks meet are a small but critical piece of infrastructure.
Network Performance and Delivery
Bandwidth, latency, throughput, content delivery networks and load balancing.
Network performance is described by three measures that are routinely confused with one another, and two infrastructure techniques exist mainly to improve them. Distinguishing capacity from delay from actual achieved rate is the key idea.
DNS Security and Local Addresses
DNSSEC, encrypted DNS, and the addresses that always point back to the machine itself.
Ordinary DNS queries travel unencrypted and unauthenticated, which makes them easy to observe or forge. Several extensions address these weaknesses in different ways. This quiz also covers the reserved addresses that always refer to the local machine.
DNS Records and Caching
Address records, aliases, caching and the value that controls how long answers are kept.
The domain name system stores several kinds of record, each answering a different question about a name. Caching those answers is what keeps the system fast, and one value controls how long a stale answer can persist.
Email Protocols and Mail Routing
Sending mail, retrieving it, and the DNS record that directs it.
Email uses one protocol to send and different protocols to retrieve, and a specific DNS record tells the sending server where to deliver. Confusing the sending and retrieving protocols is a common examination error.
Application Protocols and Secure Transport
HTTP, HTTPS, TLS, file transfer and remote login.
Application protocols define what clients and servers say to each other, and a separate security layer wraps those conversations in encryption. Understanding where that layer sits explains why some protocols have a secure variant and others do not.
Transport Protocols and Ports
TCP, UDP, port numbers and the modern transport protocol behind HTTP/3.
Two transport protocols carry almost all internet traffic, and the choice between them is a trade-off between reliability and speed. A third, newer protocol has recently begun to replace one of them for web traffic.
Network Types and Data Units
Local, wide and wireless networks, wired standards and the unit data travels in.
Networks are classified mainly by the geographic area they cover, and data crossing them is broken into standard units. These classifications and the wired standard that dominates local networking are foundational vocabulary.
Network Devices and Local Addressing
Routers, switches, modems, gateways and the hardware address burned into every interface.
Network hardware divides into devices that work within one network and devices that connect separate networks. The distinction between the two is the clearest way to understand what each box on a network diagram is doing.
Internet Basics and Addressing
What the internet actually is, the protocol that runs it, and the two addressing schemes.
The internet is not a single network but a network of networks, joined by a common protocol. That protocol has two addressing versions in use today, and the older one ran out of addresses years ago.
Internet & Web Mixed Previous Year Questions Set 9
Five previous year questions on Internet & Web, drawn from a range of past papers, with answers.
This set collects five genuine previous year questions on Internet & Web, drawn from several different examinations rather than a single paper.
