A nurse jumped into the IT industry! Network glossary

Hello!
This is Inoue, a Persian cat from Beyond Shikoku Office.

I jumped into the IT industry in a different industry with no experience, and
as a first step, I would like to write down the IT terminology related to networks that I learned along with explanations on my blog.

First of all, there are many terms that are abbreviated to the alphabet.
I had heard of it, but I had never thought about its meaning in detail.
There are so many words I've never heard before.
I was wondering if it was the English class I was not good at.
I prefer reading books to searching the internet, so here are some of the IT terms I learned from textbooks!
(My feelings that I can't express out loud) will also be written down.
I would be happy if you could read it without thinking, ``This is an unnecessary extra.''

(Please also include that protocol as standard)

(Welcome!)

・
A generic term for devices connected to a

-
A network is logically divided into multiple networks using one
subnet mask (A net-like mask can't prevent infections, right?)

A computer running DNS is called a DNS server.
(dot com~♪ dot com ♪)

- Firewall
A system installed between the local network and the Internet.
It has the role of preventing unauthorized intrusion from outside.
(It's probably a wall that's ablaze with flames.)

(LOL, that's a weird exchange? Looks interesting♪)

・HTTPS

A URL starting with "https://" indicates that encrypted communication is being performed using HTTPS.
(I never really paid attention to whether or not there was an s after http.)

・SSL
An encryption protocol used to safely exchange information over the Internet.
(M is between S and L, right?)

・
An abbreviation for cloud computing that allows you to use services without being aware of the other side of
the cloud (The other side of the internet is on the other side of the sky.)

・HTML
A language for writing documents for www, which is widely used on the Internet.

(Can you send me colorful Deco-mail as well?)

 

summary

As expected, as I wrote in the previous blog

■There are a lot of katakana!
■Many words are abbreviated in the alphabet!

⇒This is the text I used for studying this time!

“Explanation of important network terms” Written by Ryuji Kitami

I have a hard time remembering so many terms to do my job.
But if you learn one language a day, you can learn 365 languages!
I'll probably forget at least 315 of them... lol
I can't help but forget! After all, I learned something new!
Let's be positive here! The best thing to think about is that!

Growing every day, moving forward every day.
I have to update myself every day! ! !
Thank you for reading to the end.
