Selma writes the following four answers in her Computer Science examination.
State which computer terms she is describing.
“It is a signal. When the signal is received it tells the operating system that an event has occurred.”
Selma is describing
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.
In conclusion, the computer term that Selma is describing is interrupts.

A top investment bank is in the process of building a new Forex trading platform. To ensure high availability and scalability, you designed the trading platform to use an Elastic Load Balancer in front of an Auto Scaling group of On-Demand EC2 instances across multiple Availability Zones. For its database tier, you chose to use a single Amazon Aurora instance to take advantage of its distributed, fault-tolerant, and self-healing storage system. In the event of system failure on the primary database instance, what happens to Amazon Aurora during the failove
Answer:
Following are the solution to the given question:
Explanation:
Initially, Aurora will try and establish a new DB instance in the same AZ as the previous example. When Aurora can do it, he will try to create a new DB instance in another AZ.
Aurora will try and construct a new DB instance in the same disponibility zone as the original example if there is not an Amazon Aurora Replica (i.e. single instance) that does not execute Aurora Serverless. The replacement of the original example was better managed and may not work if there is, for example, an issue that impacts broadly the entire Access Service.
Carlos, a network technician, replaces a failed switch with a new switch. Carlos informs the users on the subnet served by the switch that they can reconnect to the network. One user calls to report that she is still unable to access any resources on the network. Carlos checks the indicator light for the switch port to which that user is connected. The LED light is not lit. What action should Carlos take next to resolve this problem
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.
What are water proof cameras?( write in detail)
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.

CorpServ is a small company with 14 client systems and a network printer. Because there are only a limited number of networked systems, you decide to use APIPA addressing for the network. With APIPA configured, all systems are able to communicate with each other, but you are having trouble configuring Internet access. What is the likely cause of the problem
Answer: Private addresses cannot directly communicate to hosts outside the local subnet.
Explanation:
Automatic Private IP Addressing (APIPA) allows assigning an IP address by a computer system automatically when there's no availability of a Dynamic Host Configuration Protocol (DHCP) server to perform the function.
Since after the configuration of the APIPA, all systems are able to communicate with each other, but there's trouble configuring Internet access, then private addresses cannot directly communicate to hosts outside the local subnet.

what is the basic unit of measuring storage capacity of computer?
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:
Storage devicesAll 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.
