Which of the following are true, regarding Grace Murray Hopper? Select 3 options.
She wrote the first programming manual.
She used vacuums to enter programming into the Mark I.
She preferred coding using mathematical symbols.
She developed the compiler.
She perfected the subroutine.
Answers
she wrote the first programming manual
she developed the compiler
she perfected the subroutine
explanation:
While working on the UNIVAC I and II, Hopper pioneered the idea of automatic programming and explored new ways to use the computer to code. In 1952 she developed the first compiler called A-0, which translated mathematical code into machine-readable code—an important step toward creating modern programming languages.
After the end of the war, Hopper became a research fellow on the Harvard faculty and in 1949, joined the Eckert-Mauchly Corporation, continuing her pioneering work on computer technology. Hopper was involved in the creation of UNIVAC, the first all-electronic digital computer. She invented the first computer compiler, a program that translates written instructions into codes that computers read directly. This work led her to co-develop the COBOL, one of the earliest standardized computer languages. COBOL enabled computers to respond to words in addition to numbers. Hopper also lectured widely on computers, giving up to 300 lectures per year. She predicted that computers would one day be small enough to fit on a desk and people who were not professional programmers would use them in their everyday life.

What is development tools?
A developer can create, test, and debug software using developer tools, also known as "development tools" or simply "DevTools." Modern browsers come with built-in developer tools that let you examine a website.
how to get started:
1) Prep your backlog:
The product owner should groom all existing product backlog, also known as backlog refinement, before a sprint starts and, ideally, before a sprint planning meeting.
2)Examine team availability:
Make sure to consider your team's ability to complete the suggested workload before making a full commitment to a sprint plan. Confirm any planned vacation time, obligations to other projects, and any other potential time constraints by asking team members. Adapt the workload if team members are unable to fully commit to the sprint workload.
3)Establish velocity for your team:
The amount of work that a team can finish in one sprint is a measure of their velocity. The amount that your team should do during every given sprint isn't standardized. Your team's collective experience, the number of backlog items that have been prepared for completion, and the efficiency with which you planned your sprint will all have a significant impact on your velocity.
