I have some confusion about the terms SDLC and Software Process. With respect to these (and more or less similar) terms, a have a few question.
On
SDLC in shortcut for software development life cycle for a software product that contains the process for a product the software from requirement software.. maintenance the SDLC that contain viruses methodologies like waterfall ,scream,agile that follow each the process software from the requirement , design, implementation, testing, maintains but different to how to apply this process some methodologies as agile do the multi-process in same time as implementation with design in want to write Document. in a waterfall, methodology cont go to apply the next process until the previous process finish cont do mult process at the same time example cont be go implementation with the design in the same time you should be complete the design process cont be execution 2 process at same time

Software Process - is a set of activities and associated results that produce a software product. There are 4 fundamental process activities that are common to all software processes
SDLC - is the oldest and the most widely used approach in software engineering.It follows a number of sequential phases and partitioned set of activities. Based in an engineering/construction/production new.
I very much agree with you, SDLC dates back to the 1950s and it was the first framework introduced at the time. However, I have a few notes on the SDLC phases - I'd say that there are 7 stages of the SDLC: 1.Planning 2. Requirements Analysis 3. Design 4. Development 5. Testing 6. Deployment 7. Maintenance and improvement.
Today, there are a lot of SDLC models, Waterfall being the most popular one. Though, Agile is becoming quite popular lately - yet, I find a lot of teams to be highly disappointed of Agile. "We are constantly changing things that we never get anything done" - that's the most common phrase I hear.

Software process is the testing lifecycle as it includes all the phases even the basic phases.

Let's clear these queries one by one.
There are multiple strategies or models available to develop a software. Like, Waterfall, agile, etc.
SDLC provides set of phases for the developers to follow. Each phase is a result of the privious phase.
The Unified Software Development Process or Unified Process is an iterative and incremental software development process framework.

Yes, we can map SDLC with unified process. You can go through this link for more details: https://www2.cdc.gov/cdcup/library/framework/mapping.htm
Unified Process, like most agile techniques, does not expect the general project plan defines when each use case is going to be implemented. So, object oriented analysis is required for the disign of the Information System. For more details, use this reference: https://www.sciencedirect.com/topics/computer-science/unified-process
SDLC stands for System Development Life Cycle, and it is a more or less generic term to describe whatever standard life cycle that you have implemented is.
SDLC is essentially your software process, but in my experience, most people associate it more directly with waterfall processes, as you indicated and more specifically, CMMI standards.
Typically with the SDLC, you will find that different groups have different methodologies to express it.
Since I don't recall the exact definition, there may be more linking it to the waterfall methods than just semantics. For instance, I believe Agile methodologies could be considered a type of SDLC, but I could be wrong about that.
I hope this helps.
