1970-80s which is when some of the first computers were created like apple computers which looked like a giant cube and a rectangle on the side which is very different than what we have today.
Hope this helps!

Signal processing deals with the analysis and operation of a. mechanical signals b. electrical signals c. biological signals. These can be b. digital c. analog which vary across a range of values or b. digital with only two possible values.
Explanation:
- In signal processing, a signal is a function that conveys information about a phenomenon. In electronics and telecommunications, it refers to any time varying voltage, current or electromagnetic wave that carries information.
- A signal may also be defined as an observable change in a quality such as quantity...
- A signal can be audio, video, speech, image, sonar and radar-related
- Signal processing deals with the analysis and operation of mechanical signals, electrical signals and biological signals.
- The value of the signal is an electric potential which is voltage is also a signal.
- The term analog signal usually refers to electrical signals. Analog signals may also be other mediums such as mechanical, pneumatic or hydraulic.
- An analog signal signifies a continuous signal that keeps changes with a time period. A digital signal signifies a discrete signal that carries binary data and has discrete values. Analog signals are continuous sine waves. Digital signal is square waves
Answer:
d. Individually testing a small part (or unit) of a program, typically a function, using a separate program called a test harness.
Explanation:
A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are;
1. Planning.
2. Analysis.
3. Design.
4. Development (coding).
5. Testing.
6. Implementation and execution.
7. Maintenance.
Unit testing can be defined as a software development procedure that involves the process of individually testing a small part (or unit) of a program, typically a function, using a separate program called a test harness.
This ultimately implies that, if the observed behavior of the small part of a software program is consistent with the expectations, then the unit test is considered a pass. Otherwise, the unit test failed.
