Assign an Address Through a Protocol – Ciscco Certifed Support Technici
Many operators deploy the Dynamic Host Configuration Protocol (DHCP) to • Support IPv4 hosts, which do not have any way to automatically calculate interface addresses • Support naming services (DNS) • Log and control the mapping of interface IP addresses, including controlling who can be assigned an IP address on the network • Control the…

Chapter Review – Ciscco Certifed Support Technici
This chapter used physical world examples to explain the importance and uses of packaging—or encapsulation—and addressing in computer networks. You should also have learned about what a protocol is, what metadata is, and what a tunnel is. One point to remember: addresses in computer networks can refer to many things, including a physical interface, a…

What Is a Protocol? – Ciscco Certifed Support Technici
If you were to meet the queen or president of some country, you would need to follow a protocol—when to speak, when to bow, when to curtsy, when to leave, etc. When you read a book, you read from left to right in some languages and from right to left in others. You introduce yourself…

Hosts and Devices- Ciscco Certifed Support Technici
Before we move more deeply into packaging, it is worth mentioning two other words used in computer networking with overlapping meanings: host and device. When computers were large enough to be shared resources, the host “hosted,” or ran, software, while the terminal allowed users to access the computer. Devices, on the other hand, were things…

Computer Networks- Ciscco Certifed Support Technici
Data moving through a network also has a hierarchy of labels, much like physical shipping; Figure 1-4 illustrates. Figure 1-4 Host Addresses For historical reasons, the names of the different addresses used in computer networks often overlap. A physical interface address was originally tied to an individual, physical computer interface. As computers became more powerful…

The Physical World- Ciscco Certifed Support Technici
It’s not so obvious the address on a package might change over the shipping process; Figure 1-3 illustrates. Figure 1-3 Labels and Addresses Through the Shipping Process The item itself does not have an address. Because it is used by whoever happens to own or have physical possession of it, there is no real need…

The Purpose of Packaging- Ciscco Certifed Support Technici
Packaging is the first step in shipping. Let’s look at packaging in the physical world and then consider how packaging in networking is similar and different. The Physical World Most people package things to protect them during shipment. We usually place an item in at least two packages—the commercial packaging, which tells us about the…

Chapter 1. Shipping Things- Ciscco Certifed Support Technici
This chapter covers the following exam topics: 1. Standards and Concepts 1.1 Identify the fundamental building blocks of networks. TCP/IP model, OSI model, frames and packets, addressing 1.5 Describe common network applications and protocols. TCP vs. UDP (connection-oriented vs. connectionless), FTP, SFTP, TFTP, HTTP, HTTPS, DHCP, DNS, ICMP, NTP Let’s say you have something to…

Per-Device Licensing– Cisco MV Security and MT (IoT) Design
Unlike the Co-termination model, Per-Device Licensing (PDL) requires licenses be directly assigned and tied to specific devices within the organization and tracks the license expiration for each license independently. This model provides a more traditional and consistent experience when planning for license renewals, as the license expiration dates for each license are unchanged once activated.…
