Sati [7]

Answer:

True

Explanation:

Outsourcing, in a general term, means getting help from an external source. In software development context, outsourcing is an alternative systems building approach that may involve subscribing to an application service provider or hiring an external vendor to design and create software. In outsourcing, a business employs the service of a third-party application developer to design and create a software.

Some reasons why companies outsource a service are;

i. Shortage or lack of experienced developer in-house.

ii. To save time. Outsourcing can help reduce time taken to develop a software application because companies tend to outsource a developer that has designed similar application(s) in the past.

iii. To reduce cost. Outsourcing can help save cost considerably.

Which of the following is not an algorithm?
Kipish [7]

Answer:

The correct answer is: "D. shapoo instructions (lather, rinse, repeat)".

Explanation:

Among the options given, letter D is the only one which does not apply and  may not function as an algorithm. An algorithm is a set of rules and/or instructions which aims at solving a problem and/or task, therefore, "shapoo instructions" do not classify as an algorithm because they are only written informations to explain how to use a product (lather, rinse, repeat), rather than setting a procedure for solving a problem in terms of technology tools. All the other options are examples of algorithms because they already exist as such and also function as technology tools.

(ps: mark as brainliest, please?!)
