[Must read for beginners !?] Glossary of terms that stumbles when learning programming

Thanks! This is Teppei Mimachi. It's a difficult time for me, who is sweating in the middle of summer.

Well this time There was a memo that I put together in Word when I first learned that Python and Ruby exist in programming languages, so I am modifying it a little and writing it as an article. This is a summary of terms that programming beginners are not familiar with when learning.

CRUD The minimum function required when manipulating data.

pip pip is a tool for managing Python packages

On the package ・ What is officially distributed ・ Distributed by a third party There are two main types.

Third-party packages are distributed on a site called PyPI. Official site URL => https://pypi.org/

Officially distributed ones are usually installed automatically when you install Python, but third-party distributed packages need to be installed separately.

Use pip to install the packages distributed by this third party. Using pip makes it easier to manage your packages.

protocol

The Internet connection uses the TCP / IP protocol. TCP / IP communication can be broadly divided into four functional hierarchies. The following protocols and standards apply to each layer. (1) Application layer HTTP (Hypertext Transfer Protocol) used for Web access, POP (Post Office Protocol) used for exchanging e-mails, SMTP (Simple Mail Transfer Protocol) (2) Transport layer TCP (Transmission Control Protocol) that controls data transmission to another computer, UDP (User Datagram Protocol) that sends datagrams to other hosts on the network (3) Internet layer IP(Internet Protocol) (4) Network interface layer Network standard Ethernet, etc.

Protocols with different roles function in each layer, and communication is realized only when each protocol such as HTTP and Ethernet cooperates in addition to TCP and IP. The communication protocol group is called a "protocol stack" in this way.

Relative path

Tell where your destination (information) is based on where you are (hierarchy).

Forward lookup, reverse lookup

It is to find out the host name corresponding to the IP address using DNS or the like. Also, looking up the IP address from the host name is called "forward lookup".

Example) Forward pull www.example.com → 192.0.2.100 Example) Reverse lookup 192.0.2.100 → www.example.com
