Answer:

Interrupts.

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.

The four (4) input-output (I/O) software layers includes the following;

I. User level software: it provides user programs with a simple user interface to perform input and output functions.

II. Device drivers: it controls the input-output (I/O) devices that are connected to a computer system through a wired or wireless connection.

III. Device-independent OS software: it allows for uniform interfacing and buffering for device drivers.

IV. Interrupt drivers (handlers): it is responsible for handling interruptions that occur while using a software on a computer system.

An interrupt is a signal from a program or device connected to a computer and it's typically designed to instruct the operating system (OS) that an event has occurred and requires an attention such as stopping its current activities or processes.

Explanation:

It is a desktop platform that helps a "client" computer can join from a remote location to a "host" computer. Clients can then manage and then use apps and files anywhere on network protocols.

This technology enables users to link from the remote location to a specific machine as if they were sitting beside it. Once this connection is established, users can carry out a variety of tasks as if they actually use the computer directly.

Answer:

The Internet enables effective global communication around the world and has changed the way people socialize and consume media via social networks, and has facilitated teleworking, distance learning and e-learning. The Internet has given rise to new e-commerce companies and industries, and knocked out other traditional players, but also contributed to the development of the IT bubble and burst at the turn of the millennium. To counter piracy of music and movies over the internet, new streaming services have been developed since the 00's and cut out distribution lines. Web magazines and social media have competed with many traditional media, especially the local press, and reduced the labor market for journalists. Social media may have been a tool (but not a catalyst) for revolutions such as the Arab Spring and of significance for an explosive increase in the spread of fake news and misinformation since the 2000s. Social media is believed to have had an impact on election results, but it is debatable whether fake news has had it.

Answer:

Explanation:

If the indicated network switch port has no glowing green LED then that switch port is either off or failing. This can sometimes happen even with newly replaced switches. In this case Carlos should first check to make sure that the switch port is properly installed. If so, then he should switch the port for a new one. If the LED light turns on and is still not green, then it may be an error with a faulty cable, and in this case Carlos should replace the cable with a new one, which should solve the issue.

Answer:

Underwater photography is the process of taking photographs while under water. It is usually done while scuba diving, but can be done while diving on surface supply, snorkeling, swimming, from a submersible or remotely operated underwater vehicle, or from automated cameras lowered from the surface.

Underwater photography can also be categorised as an art form and a method for recording data. Successful underwater imaging is usually done with specialized equipment and techniques. However, it offers exciting and rare photographic opportunities. Animals such as fish and marine mammals are common subjects, but photographers also pursue shipwrecks, submerged cave systems, underwater "landscapes", invertebrates, seaweeds, geological features, and portraits of fellow divers

Some cameras are made for use underwater, including modern waterproof digital cameras. The first amphibious camera was the Calypso, reintroduced as the Nikonos in 1963. The Nikonos range was designed specifically for use underwater. Nikon ended the Nikonos series in 2001[1] and its use has declined, as has that of other 35mm film systems. Sea and Sea USA made the Motor Marine III, an amphibious range-finder camera for 35mm film.[2][3]

Cameras made for dry work can also work underwater, protected by add-on housings, which are made for point and shoot cameras, compact cameras with full exposure controls, and single lens reflex cameras (SLRs). Most such housings are specific to the camera. Materials range from relatively inexpensive plastic to high-priced aluminum. Housings allow many options: users can choose housings specific to their everyday "land" cameras and use any lens. Underwater photographers generally use wide-angle lenses or macro lenses, both of which allow close focus and therefore a shorter distance to the subject, which reduces the loss of clarity to scattering. Digital media can hold many more shots than standard film (which rarely has more than 36 frames per roll). This gives digital cameras an advantage, since it is impractical to change film underwater. Other comparisons between digital and film photography also apply, and the use of film under water has declined, as it has on land.

Information/knowledge resources

Explanation:

The process of looking for answers to questions that will lead to improved knowledge about a subject is known as an inquiry. The theories of enquiry includes abduction, induction, and deduction

An inquiry can provide the reasoning behind observation by making use of the theories of inquiry and sources that provide answers (information) about the (interrelated) events of the inquiry

Therefore, information and knowledge resources are the people, materials, and places, which can be in the printed, verbal, appearance form that have the capacity to proffer answers to inquiries

Answer:

Has a central powerful computer

Explanation:

When operating a client - server network, a certain access mediun is created such that clients can access information, materials and services from a central computer, this poses great advantage in the area of security and control. Clients would be able to gain access from this central computer using either a local or wide area network. The accessibility provided through this powerful, central computer allows the the network to monitor what actions are being performed and make appropriate restrictions on the network, hence, preventing the invasion of malware and viruses. Hence, the central control is a great feature of a client - server network.

Answer:

The program is as follows:

10 INPUT RADIUS, BASE, HEIGHT

20 CIRCLE = 3.142* RADIUS * RADIUS

30 TRIANGLE = 0.5* BASE * HEIGHT

40 PRINT CIRCLE

50 PRINT TRIANGLE

60 STOP

Explanation:

The program description doesn't tally;

In other words, it is impossible to calculate the area of a triangle using the radius of a circle.

So, I designed the program to get input for radius, base and height.

Get input for radius, base and height

10 INPUT RADIUS, BASE, HEIGHT

Calculate area of circle

20 CIRCLE = 3.142* RADIUS * RADIUS

Calculate area of triangle

30 TRIANGLE = 0.5* BASE * HEIGHT

Print area of circle

40 PRINT CIRCLE

Print area of triangle

50 PRINT TRIANGLE

End of program

60 STOP

Answer:

True

Explanation:

Answer:

All data are stored on 1s and 0s computers (bits). We explain how much data we store using conditions such as kilobytes and megabytes.

Explanation:

All are stored in 1s and 0s on a computer. One of only 1 0 is called 'bit' in a computer. It takes 8 1s and 0s if we save a character in a computer, so we could say it needs 8 bits to store a character.

Computer and memory storage is frequently measured in megabytes and gigabytes (GB). A medium-sized novel includes approximately 1 MB of information. One MB is 1024 kilobytes, not a million bytes, or 1,048,576 bytes (1024x1024).

Similarly 1 GB is 1.024 MB (1024x1024x1024) bytes, or 1.073.741.824 bytes.
