Some common synonyms of adjoining are adjacent, contiguous, and juxtaposed. While all these words mean “being in close proximity,” adjoining definitely implies meeting and touching at some point or line.

transitive verb. 1 : to add or attach by joining. 2 : to lie next to or in contact with.

1 : being in actual contact : touching along a boundary or at a point the 48 contiguous states. 2 of angles : adjacent sense 2. 3 : next or near in time or sequence The fires were contiguous with the earthquake.

adjective. touching; in contact. in close proximity without actually touching; near. adjacent in time: contiguous events.

Contiguous memory allocation is basically a method in which a single contiguous section/part of memory is allocated to a process or file needing it. We can implement/achieve contiguous memory allocation by dividing the memory partitions into fixed size partitions.

Segmentation is another non-contiguous memory allocation scheme like paging. like paging, in segmentation, process isn’t divided indiscriminately into mounted(fixed) size pages. It is variable size partitioning theme….Difference between Paging and Segmentation:

S.NO	Paging	Segmentation
10.	Paging is invisible to the user.	Segmentation is visible to the user.

Advantages of single user operating system:

• Supports one user at a time:- In these systems one user is only active at a time.
• Easy to maintain:-
• Less chance to damage:-
• Concentrate on one task:-
• Tasks take longer time to complete:-
• Idle time is higher:-
• Examples of single user operating system:

Que.	The major disadvantage with linked allocation is that :
b.	external fragmentation
c.	there is no sequential access
d.	there is only sequential access
	Answer:there is only sequential access

Single allocation is the simplest memory management technique. All the computer’s memory, usually with the exception of a small portion reserved for the operating system, is available to the single application. MS-DOS is an example of a system which allocates memory in this way.

Paging is used for faster access to data. When a program needs a page, it is available in the main memory as the OS copies a certain number of pages from your storage device to main memory. Paging allows the physical address space of a process to be noncontiguous.

In many situations, it is not possible to allocate data in a LIFO fashion with a stack. In this case, data is dynamically allocated from a pool of memory commonly called the heap. Heap allocation is considerably slower and more complex than stack allocation and may also result in allocations scattered all over memory.

What is Best Fit Algorithm? Best Fit is a memory management algorithm; it deals with allocating smallest free partition which meets the requirement of the requesting process. So we will take the block size and process size and return the output of the process and which block is to be allocated to a process.

Best fit is not the best allocation strategy, but it is better than first fit and next fit. The reason is because it suffers from less fragmentation problems than the latter two. Consider a micro heap of 64 bytes. First we fill it by allocating one 32 and two 16 byte blocks in that order.

Disadvantages of Best-Fit Allocation : It is a Slow Process. Checking the whole memory for each job makes the working of the operating system very slow. It takes a lot of time to complete the work. Attention reader!

Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. A straight line will result from a simple linear regression analysis of two or more independent variables.

A line of best fit is drawn through a scatterplot to find the direction of an association between two variables. This line of best fit can then be used to make predictions. To draw a line of best fit, balance the number of points above the line with the number of points below the line.

Mentor: A line of best fit is often useful to attempt to represent data with the equation of a straight line in order to predict values that may not be displayed on the plot. The line of best fit is determined by the correlation between the two variables on a scatter plot.

A trendline is a line drawn over pivot highs or under pivot lows to show the prevailing direction of price. Trendlines are a visual representation of support and resistance in any time frame. They show direction and speed of price, and also describe patterns during periods of price contraction.

The five different types of trend lines are:

• Linear.
• Polynomial.
• Exponential.
• Logarithmic.
• Power.

If increase in one set of data causes the other set to increase, then the trend shown is called a positive trend. If one set of data increases, then the other set does not seem to increase or decrease then it does not have any trend.

A trend is the general direction in which something is developing or changing over time. A projection is a prediction of future change. Trends and projections are usually illustrated using line graphs in which the horizontal axis represents time.

The y-value of each point generally increases as the x-value increases. We can add a trend line to this graph by adding a line that goes through the middle of the points. Notice that the trend line has a positive slope.

A “trend” is an upwards or downwards shift in a data set over time. In economics, “trend analysis” usually refers to analysis on past trends in market trading; it allows you to predict what might happen to the market in the future. It might, for instance, be used to predict a trend such as a bull market run.

A trend is a general direction into which something is changing, developing, or veering toward. The term may also mean a fashion or craze, i.e., a fad. The verb ‘to trend’ means to develop or change in a general direction.

Trend is defined as to go in a general direction or to have a tendency to go in a certain way. An example of trend is for a plain to stretch westward across a state. An example of trend is when the number of murders in a city reduce downward. The general direction of a market.
