You've just installed a new video card in a user's Windows workstation. When the system is powered on the screen is blank. You

After having verified that the video cable is installed correctly we should check to see that the computer's RAM is correctly fastened to the motherboard and functional.

The question states that the video card being installed is new, therefore we can comfortably assume that the card itself is not the issue. Other computer components that can cause a blank screen immediately upon powering on the workstation are:

RAM
Hard drive
Bad video driver.
Monitor input is faulty

however, assuming the installation was performed correctly, it is not likely to be caused by a bad video driver and a faulty monitor input is very improbable given that there are very few ways this can break to begin with.

A bad or missing hard drive may cause this kind of issue because the workstation will not have a windows file to boot. In most cases, this will not cause a completely blank screen without first allowing access to the BIOS.

After having verified that the video cable is installed correctly, the very next thing you should check is if the RAM is installed correctly. This is because the issue explained is exactly what will happen if a workstation attempts to boot without RAM, and also because it is the easiest fix among the possible causes and any troubleshooting should always be performed in order from the easiest fix to the most difficult.

Explain why there is an overlap of skills and qualities in design professions

strojnjashka [21]

The design process is the same in all creative occupations, thus, similar skills and qualities are required. The work of an architect, Craftperson, Fine Artist, or an Interior designer is to design. Whether one occupation designs clothing and associated fashions or another one designs interiors of building, they all design. Most people who work as designers possess similar personal qualities like creativity, better communication skills, and high skill set.

Every telecommunication setup uses two devices: one device to transmit data and one device to receive data. Which device transmi

alexandr1967 [171]

Answer:

Cell.

Explanation:

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.

Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.

Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.

In the field of telecommunication, all telecommunication setup are designed and developed to make use of two network devices: one device is typically used for the transmission of data while the other device is used to receive data that are sent on the network.

Generally, cell towers are tall poles that are used to transmit frequencies to mobile phones.

How are static variables and methods created in Java? What happens if a non-static method of a class tries to access a static va

9966 [12]

Answer:

Static variables are the variables decaraed with keyword static, static variables must be deacraled inside the class body, means we can not declare a static variable inside a method or consttructor, static variable belongs to class, for a class only one copy is created for static variable and used by all the objects/instances.

Static variable can access with class name like

X.i

Static method are the methods defined with static keyword, static method are also part of a class, we can access static meethod using class name like

X.printI()

Explanation:

class X

{

//to create a static variable we need use static keyword with variable name like

public static int i;

// to create a static method we need to use static keyword while defining a method like

public static void printHello() {

System.out.println("Hello");

}

* A non static method can access static variable of a class there is no issue

* with that we can use a static variable in a non static method like

public void printI() {

System.out.println(i);

}

* As long as the class exist in JVM static variables will be there, as static

* variable belong to class not with the instance,

* it does not matters if there are instance exist or not

Two communicating devices are using a single-bit even parity check for error detection. The transmitter sends the byte 10101010

icang [17]

Answer:

The receiver will not detect the error.

Explanation:

The byte sent by transmitter: 10101010

The byte received by receiver due to channel noise: 10011010

If you see the bold part of the both sent and received bytes you can see that the number of bits changed is 2.

The two communicating devices are using a single-bit even parity check. Here there are two changed bits so this error will not be detected as this single bit even parity check scheme has a limit and it detects the error when the value of changed bit is odd but here it is even.

This parity scheme basically works well with the odd number of bit errors.
