click on start, and than on all programs click on accessorise, and than click on run.
Now type diskmgmt.msc press ok and not you should be able to see all of your drives right click your pen drive and the click a delete and that should work, if it does not email this address cujok3329@gmail.com

Difference between contiguous and non contiguous memory?
In contiguous allocation there is no overhead during execution of a program. In noncontiguous allocation address translation is performed during execution Contiguous memory allocates single area of memory Noncontigious memory allocates several memory areas - one memory are to each component of a process
WHAT IS SINGLE USER CONTIGUOS SCHEME?
Single user contiguous scheme is a memory allocation technique where a single block of contiguous memory is allocated to a process. This means that the entire memory space needed by a process must be available in a single block without any breaks or fragmentation. It simplifies memory management but can lead to wastage of memory due to fragmentation.
Compare Contiguous memory allocation with internal fragmentation?
in early, computer system has contiguous memory allocation,each process is allocated in a single contiguous(together) memory!!(allocating into memory addresses one by one,)it has tackled memory fragmentation(both internal and external). not allocating for a fixed size memory block.so no internal fragmentation, allocating contiguously ,so no external fragmentation!!!

What are some of the benefits of using an array as opposed to a medium-sized list of variables?
Arrays exist in contiguous memory, so you can use simple pointer arithmetic to access any element by its offset from the start address (the array name is an alias for the start address), and can pass the entire array to functions as a single entity. Lists of variables are not guaranteed to exist in contiguous memory, and cannot be passed to functions as a single entity.

What are the different between array and variables?
A variable is a reference to a single object (often a number, character, or string of characters). An array is a reference to a contiguous block of memory in which zero or more individual objects.
What is the real estate definition of Floor contiguous?
Contiguous Space: Multiple suites/spaces within the same building and on the same floor which can be combined and rented to a single tenant.
When two companies combine to form a single company is called what?
When two companies combine to form a single company, it is called an amalgamation or merger.
What is contiguous memory in c plus plus?
Contiguous memory refers to a single block of consecutive memory addresses. All data types larger than a char require contiguous memory addresses. For any given data type T, sizeof (T) tells us how many bytes of contiguous memory will be allocated to an object of that type: std::cout << "sizeof (char) == " << sizeof (char) << std::endl; std::cout << "sizeof (int) == " << sizeof (int) << std::endl; std::cout << "sizeof (double) == " << sizeof (double) << std::endl; struct X {/* ... */}; std::cout << "sizeof (X) == " << sizeof (X) << std::endl; When we speak of contiguous memory, we don't usually refer to the number of bytes allocated to a given type; it can be taken as read that those bytes will be allocated contiguously such that the low-order byte refers to the whole object, regardless of its length. Typically we use the term contiguous memory when referring to an array of objects. All objects in an array (the array elements) are exactly the same length (in bytes) and because they are allocated contiguously it is trivial to calculate the offset address of any one element relative to any other element in the same array. This is precisely how the array suffix operator works using only a zero-based index; the operator is nothing more than a convenient method of implementing pointer arithmetic. The upshot is that all arrays permit constant-time random access to any element in the array. Arrays are dense data structures. That is, there is no additional memory required to maintain the structure. The only information we need to keep track of is the start address and the number of elements. However, the downside of contiguous memory allocations is that whenever we wish to increase the amount of memory allocated we often have to move the entire allocation to new memory. The larger the allocation the more costly this becomes. Moreover, inserting new data means we must move elements to make room. This is why variable-length arrays typically reserve additional memory for moderate expansion while new elements are always pushed onto the end of the array rather than inserted in the middle. Linked-lists are non-contiguous data structures which make use of additional memory to maintain links between the elements. As such, the elements need not move once allocated. If we want to change the element sequence or insert a new element into the sequence we simply update the affected links; the elements themselves remain wherever they were originally allocated. Some data structures make use of both contiguous and non-contiguous allocations. A deque (a double-ended queue, pronounced deck) is a typical example because it is usually implemented as a linked-list of separate arrays. Each array is contiguous but the list of arrays is not necessarily contiguous.
What is Single-User Contiguous Scheme?
A single user scheme supports one user on one computer running one job at a time. Sharing is not possible.
