Answer:
It allows many developers to work on the same project from anywhere at the same time
Project files are maintained in a central repository
The process may require file locking, depending on file type
Explanation:
The two main types of version control system are the centralized version control system and distributed control system
The centralized version control system is a control system whereby all programmers work on and make their individual changes to a single single copy of the project stored and maintained in a central repository, such as a server
In order to solve the problem of several developers working on each others work simultaneously, a centralized version control system makes use of the lock-modify-unlock model
The three options are therefore;
It allows many developers to work on the same project from anywhere at the same time
Project files are maintained in a central repository

A user is configuring an email client application and decides to use the TCP/IP suite protocol that will store all messages on the email server so that they can be synchronized across a laptop, a smartphone, and a web email client. This protocol will store the email messages on the email server until the user explicitly deletes them.Which of the following TCP/IP port numbers will the client application typically use while using this protocol to contact the email server?A. 21B. 80C. 110D. 143
Answer:
D. 143
Explanation:
A server that allows the entire management of an email account through more than one email client such that the clients the messages of the clients are stored on the server pending being deleted by the user, is an IMAP server
The port that the IMAP server listens to is the port number 143, therefore, the client application typically makes use of port 143 while using the TCP/IP protocol to contact the email server
Don's company has contracted with a service provider to receive a computing platform for all employees, complete with an operating system, database services, and a Web server. Don develops applications using tools delivered by the service provider. What type of service has Don's company signed up for?
Answer:
Platform as a Service (PaaS).
Explanation:
Cloud computing can be defined as a form of data computing which requires the use of shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Basically, cloud computing comprises three (3) service models and these include;
1. Platform as a Service (PaaS).
2. Software as a Service (SaaS).
3. Infrastructure as a Service (IaaS).
Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.
The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.
Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).
Hence, the advantage of the Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.
These are the different types of Platform as a Service;
1. Private PaaS.
2. Public PaaS.
3. Open PaaS.
4. Mobile PaaS.
5. Communications PaaS.
6. Hybrid PaaS.
In this scenario, the type of service Don's company signed up for is called Platform as a Service (PaaS).

(c) The average marks of students of G.C.E. (O/L) examination
(d) The top ten total marks of students of G.C.E. (O/L) examination
Answer:
(a) Sithum's G.C.E. (O/L) examination results
Explanation:
Raw data which is also known as primary data, are the data collected when performing a research, investigation or study, which are obtained through a survey, experiment, or observation and from which correlations and distributions can be calculated, only when the data is complete
Therefore, raw data is unprocessed data, and the option which can be considered as raw data is the option which is not processed, which is Sithum's G.C.E. (O/L) examination results.
A company developed a web application and deployed it on a fleet of EC2 instances that uses Amazon SQS. The requests are saved as messages in the SQS queue, which is configured with the maximum message retention period. However, after thirteen days of operation, the web application suddenly crashed and there are 10,000 unprocessed messages that are still waiting in the queue. Since they developed the application, they can easily resolve the issue but they need to send a communication to the users on the issue. What information should they provide and what will happen to the unprocessed messages?
Answer: Tell the users that the application will be operational shortly and then all the received requests will be processed when there's a restart of the web application.
Explanation:
After the development of the application, even though the issue can be resolved, a communication needs to be passed across to the users.
The information that should be provided is that the users should be told that the application will be operational shortly after which the received requests will be processed when there's a restart of the web application.
