- On behalf of the fathers of the internet,…I would like to apologize for something.…You see, you've been taught that the protocol…that we use to power the internet is called TCP/IP.…But if you look at it very closely…you'll see it says TCP slash IP,…and there's a reason for that.…There really isn't just one protocol called TCP/IP.…There's lots and lots and lots of protocols.…For example, the IP means Internet Protocol,…and that just has to do with the numbering system,…how to give everybody an IP address.…
So on the TCP part, that's really kind of a misnomer too,…because there isn't just a TCP protocol.…Now keep in mind,…this part is how we get data between computers.…This gives us a phone number.…This says, "How do we talk over the phone?"…So TCP is the most common way to talk on the phone,…but there's other ones, for example, UDP and ICMP.…So let's go through each one of these.…First of all, the reason we call it TCP/IP…is because TCP, the Transmission Control Protocol,…is by far the most common protocol that we use with IP.…
The CompTIA A+ 220-901 exam is comprised of six key parts. The fifth, networking, is covered by this course. Instructor Mike Meyers provides an introduction to networking by exploring cables, network IDs, IP addresses, and ports. He explains how to deal with a DNS, configure a router, and set up a wireless network while applying security standards. He also discusses Internet connections, including dial-up, broadband, wireless, and more.
Note: The six courses designed for the CompTIA A+ (220-901) exam preparation include core processing, core hardware, peripherals and building a PC, displays and printers, networking, and laptops and mobile devices.
