Component and deployment diagrams are different UML diagrams. They both show components - but at different levels.
Component diagram shows components and dependencies between them, interfaces they provide (implement) or require, classes that realize component. It has no deployment nodes - as deployment diagram does.
Deployment diagram shows deployment architecture of system - how components and artifacts are deployed to nodes - execution environments and devices.
Though we can show dependencies between components both on component diagrams as well as on deployment diagrams, but we are not showing implementation of components on deployment diagrams as we do on component diagrams.
Note, that in UML 1.x deployment diagrams components were directly deployed to nodes. In UML 2.x artifacts are deployed to nodes, and artifacts could manifest components. So, on deployment diagrams components are now deployed to nodes indirectly through artifacts, and generally speaking in UML 2 deployment diagram could show only nodes and artifacts, and no components.

To understand what is software key first, we need to understand what software is. Software is a set of programs and instructions for a computer that determine how the device should operate. It controls the hardware of the computer and provides the functionality required by the users.
Software Key A key is an alphanumeric code used to authenticate or authorize software. This is often known as an activation key or serial key. The software key is usually used during the installation process of the software.
Software keys can work in different ways. Some software keys are unique to a particular version or license of the software. In this case, the software key is required to properly install and run the software. Other software keys can be used on multiple computers. In this case, the software key is used only to properly authorize the software.
Why is software key important? Software keys are important for authorization and authentication of software. It helps the authors of the software to protect the copy of their software and protect it from illegal use.

LPU provides a range of scholarship opportunities based on various criteria only. One of the criteria is the candidate's academic performance, where scholarships are awarded to students who have achieved more than 70% in their intermediate exams.
Additionally, scholarships are also available based on the candidate's performance in the LPUNEST exam. This means that students who excel in both their 10+2 percentages and the LPUNEST exam have the chance to receive scholarships. Furthermore, LPU also recognizes the achievements of the toppers in the university by providing them with scholarships.
Apart from academic performance, LPU offers scholarships based on other factors as well. These include national level tests such as JEE (Main), NEET, UCEED, CAT, MAT, GATE, GPAT, as well as performance in sports, cultural activities, research and development, co-curricular activities, social service, and bravery awards. Moreover, there are specific scholarship schemes for PhD students and toppers of school education boards.
In addition to scholarships, LPU also provides financial aid to those in need. This includes financial aid for serving or retired defense personnel, CAPF, para-military personnel, and their dependents.
Financial aid is also available for orphans and individuals with certain disabilities. It is important to note that while applying for any of these scholarship categories, the required set of documents must be submitted as well.
Hope this helps.
Good luck.

It depends of how much education you have.
is the most important part every business must follow, in order to build and release a project successfully, as it is the foundation to key planning and implementation.
It is because a mobile is operated on a battery with low power and therefore it sends signals on low(uplink) frequencies whereas a base station is driven by high power and can easily send signals on high(downlink) frequencies. This can be verified by Friis equation which says Transmitted power and Transmitted frequency are directly proportional.

It is a process of storing data in memory area called Buffers while data is being transferred between two devices or between a device and an application. Buffering is done for 3 reasons:
a. To cope with the speed mismatch between producer (or sender) and consumer (or receiver) of a data stream.
b. To adapt between the devices having different data-transfer size.
c. To support copy semantics for application I/O.
In-House development means that a company has programmers on its staff and develops software internally. Outsourced development is when a company hires a firm to develop a custom applicaation Packaged software is what you purchase when you goto a store and purchase software off-the-shelf.
To help you get an idea of the kind of jobs in software engineering, I took a quick look at online job listings for software engineering. The types of job titles that showed up were Software Engineering Technician, Software Engineering Programmer, Software Engineering Manager, Software Engineering Director, and Technical Writer in Software Engineering.
A combinational circuit's output depends only on its current inputs. This means, it has a truth table. A sequential circuit's output depends on its previous inputs. This means, it's output will depend on which state it is.
It can be cheaper. The people who are doing it are more familiar with the company and the systems within the company. The people commissioning the software are more familiar with their own developers. There can be better communications as the work is being done within the company. The in-house developers can give more time to the project. They will follow in-house standards which can make things easier to work with in the future. These are just some of many advantages.
Software myths are common beliefs that are propogated as truths, may seem to be plausible, but are false. Believing in software myths at best leads to low productivity and poor software quality and at worst leads to failed projects.
Here are just a few myths in the software world:
There are many more myths out there, but the common thread is that these myths are believed because people do not get hard evidence on what works in software development and what doesn't. People confuse their personal biases and beliefs with facts.
If you want facts about what works and what doesn't in software development then you want to get books like: The Economics of Software Quality by Capers Jones (link below), which document hard evidence after considering 10,000+ projects.
Other quality authors are Tom Demarco and Edward Yourdon.
If only one network address is available on a host, all transport connections on that machine have to use it. When a TPDU comes in, some way is needed to tell which process to give it to. This situation, called upward multiplexing. While if a user needs more bandwidth than one virtual circuit can provide, a way out is to open multiple network connections and distribute the traffic among them on a round-robin basis. This modus operandi is called downward multiplexing.
Yes. Whenever a thread needs to read or write to memory shared with concurrent threads, it must prevent other threads from writing to that memory at the same time. That is, the threads need to be synchronised. Typically, a thread will acquire a lock on that memory, releasing it when it has finished with the memory. Only one thread can acquire a lock at any given time, so if the lock is already acquired by another thread, the current thread must wait for it to be released.
However, there are often times where two or more locks need to be acquired. So long as every thread acquires locks in the exact same order this is not a problem. But if a thread acquires the locks in a different order, we can easily end up with a deadlock.
Consider the following pseudocode:
function f ()
{
acquire lock A
acquire lock B
// ...
release lock B
release lock A
}
function g ()
{
acquire lock B
acquire lock A
// ...
release lock A
release lock B
}
If f is invoked in one thread and g in another, we can easily end up with f acquiring lock A while g acquires lock B. Function f is then left in limbo waiting for function g to release lock B while g is waiting for f to release lock A. They are deadlocked because neither can progress any further.
A risk table a.k.a. risk database is a list of all the risks that could affect your software project.
A risk is an event that is not guaranteed to happen (i.e. not 100%) that if triggered would affect your project positively or negatively. Most of the time when people discuss risks in software projects they are assuming that the risk is negative.
If the risk event is triggered, i.e. comes to pass, then there is a severity associated with that event. Risks severity is typically low, medium, high, or catastrophic.
You may have a strategy that would mitigate the risk. Mitigating strategies are invoked after a risk has occurredto reduce the severity of the outcome.
The risk table will at least list the following for each row:
Example of one line of the risk table:
Typical risks include:
As we recheck our answer sheets before submitting to the teacher. We also tests the software before we handover it to the customer, so that we can check if the product meets the requirement of the customer or not.
