Answer:

True.

Explanation:

Microsoft Word refers to a word processing software application or program developed by Microsoft Inc. to enable its users to type, format and save text-based documents.

In Computer science, there are specific key combinations (short cut) that avail end users the opportunity to perform specific functions without having to go through a series of step.

For example, when you press the Alt button and function key 4 (F4) at the same time, it would close the current open window.

Hence, Alt + F4 is a short cut key that can be used to close a document in MS word.

______ is the software that blocks a user from being able to access your computer.

antiseptic1488 [7]

The answer is firewall. It is a network security device that observes inbound and outbound network traffic and chooses whether to allow or block specific traffic based on a well-defined set of security rules. Firewalls have been a first line of protection in network security for over 25 years. The firewall present a barrier between measured and secured internal networks that can be trusted and untrusted outside networks, for example the Internet. A firewall can be software, hardware, or even both.

Which type of app is the best choice when it is critical to be able to use the device's features but performance is not critical

lisov135 [29]

Answer:

Hybrid.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.

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; planning, analysis, design, development (coding), testing, implementation and execution, and maintenance.

Some of the models used in the software development life cycle (SDLC) are;

I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.

Basically, softwares are categorized into three (3) main categories based on the development platform and these are;

a. Web application.

b. Native application.

c. Hybrid application.

A hybrid application is a type of software application that is designed based on the combination of the elements of both web applications and native applications.

Typically, a hybrid application is a web application that is developed in a native application shell, using a standardized web programming language such as CSS, JavaScript, and HTML.

Generally, a hybrid application avails a programmer the opportunity to write a code for a mobile application once while accommodating or being compatible with multiple app platforms such as Android, Windows, iOS, etc.

Hence, a hybrid application is the best choice of an application when it's critical for the end users to be able to use the features associated with a device such as a mobile phone but performance isn't critical.

What are the limits of hashing and verifying that files haven’t changed?

earnstyle [38]

The hashing function can take any number of key-value pairs and there is no specific limit to it.

<h3>What is hashing?</h3>

Hashing is a file-based algorithm for producing a fixed-length bit string value. A file is essentially a collection of data blocks. The length of the data is reduced by hashing to a fixed number or key that represents the original string.

When hashing is employed, the hash function may plot all of the keys and values to what the real size of the table is, demonstrating that the hashing function can take any number of key-value pairs with no restriction.

However, if the passwords are hashed in encryption, recovering the passwords is extremely difficult.

Thus, the hashing function can take any number of key-value pairs and there is no specific limit to it.
