All you need to do is to lock the Database on which you want to work and after working on it you unlock it by using key words defined by the tool you are using.
As far as my experience is concerned 99.9% of the times we lock the TABLE on which we want to make changes or execute some queries.
Different tools have different syntax to do this for example for MYSQL we use:
LOCK TABLES table_name [READ | WRITE]
to lock the table and when we are done working on it we unlock it by executing :

why is it important for you to understand and describe the internal and external components of a computer in the workplace
Hi! I have been troubleshooting and building PCs all my life and I find it very important to know the the internal core components of a PC and how they function that way when errors occur you can attempt to fix the problem.
Ex1: Lets say your BIOS identifies a problem with a RAM slot you would be able to know that your RAM slot is either shorted or there is a problem with the RAM stick you inserted.
Ex2: Now your monitor is flashing and turning colors randomly. You could make an inference that either your monitor is prongs are broken, your cable prongs could be bent, your cable might not be plugged in all the way, or your external or integrated GPU is toast.
Hope this might've showed you something

Before you enter an intersection on a green light, make sure _____.
Answer:Make sure nobody doesn't go on a red light when you are going on your green light.
Explanation:
Before entering an intersection on a green light, ensure the path is clear and there are no lingering hazards. Adequate distance and timing judgment are critical, along with preparing to stop at a yellow light to navigate safely.
Before you enter an intersection on a green light, make sure the intersection is clear of traffic and it is safe to proceed. Even when the traffic light is green, there may be circumstances where vehicles or pedestrians are still in the intersection, which could lead to potential hazards. It is also essential to be aware of the 'no-win' zone described by traffic engineers, where a driver is too far to safely make it through the intersection before the light changes, yet too close to stop safely. This highlights the importance of judging the distance and timing accurately to make safe decisions when driving. Driving at a moderate speed, being prepared to stop when the light turns yellow, and giving yourself enough time to react are key to safely navigating intersections.
Which of the following is a good technique to use when driving in an urban environment
A. Passing
B. Drowsy driving
C. Cover braking
D. Drifting
Answer:
A. Passing
Explanation:
Passing is a good technique to use when driving in an urban environment .
The correct answer is C. Cover braking
Explanation:
Driving in cities has multiple challenges in comparison to driving in small settlements or highways between cities. One of the techniques that you should use when driving in an urban environment is cover braking that implies hovering your foot over the brake to use if it is required. This technique is recommended because due to high traffic, people or traffic lights in cities, you might need to stop your car suddenly and by using cover braking you can do it effectively and in this way avoid possible accidents. Thus, cover braking is a good technique to use when driving in an urban environment.

Create a horizontal line across middle of the entire form. To code this the ____ values are the same.
To make a horizontal line in mathematics you require some sort of constant function. Where no matter the input x the output y will always equal to a certain number n.
For eg. consider n = 2. Hence the graph of line has an equation of y = n making it always intercept in (x, n). As x increases the y is the same therefore the horizontal infinite line emerges.
So to plot or code this kind of program you need to have the same values of y therefore y is a constant function.
Hope this helps.

The answer is "Y".
Explanation:
In programming language and mathematics both use coordinates to represent horizontal line and both terms description as follows:
In visual programming, To represent an object graphically we use coordinates. The "y" axis is used to represent a horizontal line and it creates a line from the entire form. In mathematics, To make a horizontal line in the entire form the constant function is used.

Recommendation from I:
Explanation:
I recommend science report, I love science so it would benefit you. The science report title would be the Theory of Cell Evolution.
Column one:
Prokaryotic and Eukaryotic Cells
Prokaryotic cells are simple structured cells such as bacteria and algae. A prokaryotic consists of a thin bio-lipid layer, cytoplasm, scattered dna and little to almost no ribosomes. Prokaryotic cells create their own energy and reproduce with no assistance from splitting based organelles. Eukaryotic cells are more complex cells. Eukaryotic cells come from ancestor Eukaryotic and Prokaryotic cells. Eukaryotic cells are made of different organelles which serves their own purpose in the cell. The cell membrane, cytoplasm, nucleus, golgi apparatus, endoplasmic reticulum, mitochondria, ribosomes, vacuoles, and depending on the type of Eukaryotic, centrioles and chloroplasts.
How modern Eukaryotic Cells came to be
The Theory of Cell Evolution states that Eukaryotics have built from Prokaryotics. The first Eukaryotic cell was believed to be loose cytoplasm and cell membrane. This Eukaryotic cell had it's own Nucleus. This Eukaryotic consumed a Prokaryotic cell which produced it's own energy, which led to the creation of a dependant mitochondria organelle. This Eukaryotic cell later then consumed another Prokaryotic cell which produced it's own proteins. This Prokaryotic led to the creation of the Golgi Apparatus, an organelle. These Eukaryotic cells ended up reproducing therefore creating more present Eukaryotic cells, which consumed more Prokaryotic cell basis with each it's own purpose.
Animal and Plant cells
Animal and plant cells are both Eukaryotic cells. An animal cell consists of all current organelles but no chloroplast or cell wall. Animal cells have centrioles which aid in their cell reproduction. Plant cells consist of all current organelles including chloroplasts, cell wall, and a vacuole which takes up 95% of the cell's structure, but no centriole to aid it's cell reproduction. This is because plant cells rely on their bio-protein and nutrient cell wall to aid in cell reproduction. There are different types of cells for their own based system though, such as muscle cells, brain cells, blood cells, lung cells, and etc.

The Biography and Life of Henry Ford.
Column One: Who was Henry Ford?
Henry Ford was the founder of Ford Motor Company and also the mass producer of the automobile. Henry Ford was born in 1863. At the age of 16, he worked as a machinist apprentice. Later, Henry began to work the family farm while still working on creating steam engines. Henry had a big interest in steam engines, which would later contribute to him building his first working automobile.
Column Two: How did Henry Ford contribute to our society?
After marrying in 1888, Ford was hired to work for Edison Illuminating Company. His position was an engineer, and Ford began to accelerate his position in the company quickly. After a while, Ford created his first operating vehicle. This was called the "Quadricycle." Ford wanted to improve on his models, so he founded the Company Ford with others. Ford then began to develop methods of mass-producing automobiles to sell to the public. After success in business, he bought the whole company and owned it all by himself. Ford began to mass-produce automobiles. It is said that " The mass production techniques Henry Ford championed eventually allowed Ford Motor Company to turn out one Model T every 24 seconds." Ford passed away in 1945. He decided to give ownership to his son Edsel Ford before he died, but Edsel sadly died before Henry Ford. The Ford company's ownership was given to Ford's grandson, Henry Ford II.

the introduction of the 8-bit computer expanded the number of bytes available for encoding. This led to the development of
a: octets.
b: Apple and Xerox.
c: ASCII.
d: Unicode.
Answer:
C. ASCII
Explanation:
ASCII is the abbreviation for American Standard Code for Information Interchange. It is a system of representing characters using 8-bits. The 8th bit is actually a parity bit used for parity check which is a form of error-checking. Since the parity check uses up one bit, only 7 bits are available for characters representation. Therefore, ASCII typically represents only 128 characters (calculated from 2 ^ 7 = 128). For example the ASCII code for the lower case letter b is 98 and that of upper case letter A is 65.

In web developing, what are the differences between front-end developer, back-end developer and full stuck developer?
When it comes to front end, back end and full stack developer, the difference is determined by :
front end (the visible parts of a website)
back end (the “under the hood” databases and infrastructure)
full stack (a hybrid of both)
And front end developers work on technologies that are used to build front end(which is what clients visiting that website see)of application like HTML,CSS, Javascript ( Node js, Angular are also now used ).
Similarly back end developers work on back end technologies like Node js.
Full stack developers work on both front end and back end developers and know both end technologies as well.
For example :
MEAN Stack developer where
M stands for Mongoose ( Back end database technology )
E stands for Express ( Back end technology)
A stands for angular ( front end technology)
N stands for Node ( back end technology)
