Answer:

3 Reasons to Use Cash and 3 Reasons to Choose Credit

Credit and debit cards have become so ubiquitous, you'd be forgiven for thinking physical cash is just a couple years away from being declared obsolete and worthless by the government.

Well, as it turns out, the death of dead presidents is greatly exaggerated, as over $1.25 trillion still circulates around the United States alone.

Way too many people use cash for it to ever go away completely, regardless of how much plastic gets wiped every day.

Easier to Watch and Control Your Spending

Actually seeing the cash you owe, as opposed to simply staring at a generic card with no monetary value of its own, can remind you to spend less overall, since all of a sudden the money is real, and real valuable at that.

Financial guru Ramit Sethi, for example, lost his credit card, and spent nothing but cash until a replacement came. He reported spending 18% less when forced to watch his green wad dwindle in real-time.

Some Places Still Don't Take Plastic (or Require a Minimum Purchase Amount)

Amazingly, over half of all small businesses won't take cards, likely because they can't afford the fees.

It's always good to keep at least some cash on you in case you need to make a purchase from one of these places.

Explanation:

3 Reasons To Use Cash (and 3 Reasons To Choose Credit)

Credit and debit cards have become so ubiquitous, you'd be forgiven for thinking physical cash is just a couple years away from being declared obsolete and worthless by the government.

Well, as it turns out, the death of dead presidents is greatly exaggerated, as over $1.25 trillion still circulates around the United States alone.

Way too many people use cash for it to ever go away completely, regardless of how much plastic gets wiped every day.

So why in the world would anydiv still pay with Georges and Bens? Here are a few good reasons why:

Less Chance of Identity Theft

Few things are scarier than hearing that the store you regularly swipe your card at just had a security breach, and that some anonymous criminal may have your identity at their disposal.

Paying cash eliminates that issue -- chunks of metal and pieces of paper stacked in a register tells fraudsters absolutely nothing, while the information sent to vulnerable computers via your bank card can reveal everything.

Easier to Watch and Control Your Spending

Actually seeing the cash you owe, as opposed to simply staring at a generic card with no monetary value of its own, can remind you to spend less overall, since all of a sudden the money is real, and real valuable at that.

Financial guru Ramit Sethi, for example, lost his credit card, and spent nothing but cash until a replacement came. He reported spending 18% less when forced to watch his green wad dwindle in real-time.

Some Places Still Don't Take Plastic (or Require a Minimum Purchase Amount)

Amazingly, over half of all small businesses won't take cards, likely because they can't afford the fees.

It's always good to keep at least some cash on you in case you need to make a purchase from one of these places.

Even if they accept cards, some of these businesses might only do so if you spend X amount, in order to override the fee.

If you entered the store to spend more than the minimum amount, then swipe away. But if you only want a loaf of bread, and they want you to spend $10 before they'll accept your card, just pay for your bread with bread.

That all being said though, there are several cases where plastic owns cash. Here are a few of those:

Online Purchases

Increasing amounts of items can now only be purchased online and with a credit card, or at the very least are extremely difficult to cover with cash.

Plane tickets, while still technically available at a travel agent's physical office, are usually much, much cheaper online, where you can't obviously use cash. The same thing goes for e-books, MP3s, subscriptions to streaming sites, and the like.

The more you shop online, the more reliant you will become on cards in your everyday life.

Computer system with a 32-bit logical address and 4k-byte page size. assume that each entry of a page table consists of 4bytes.
Annette [7]

The number of bits in the physical address is 26 bits. The number of entries in a page table is \mathbf{2^{20}} entries. The size of the page table in a one-level paging scheme is 4MB.

<h3>
What is paging in Operating System?</h3>

Paging is a storage method used in operating systems to recover activities as pages from secondary storage and place them in primary memory. The basic purpose of pagination is to separate each procedure into pages.

We are given the following parameters:

  • 32-bit logical address
  • Page size = 4 KB = \mathbf{2^{12} \ bytes }
  • Size of each Page table entry = 4 bytes

Suppose the system supports physical memory size = 64 MB = \mathbf{2^{26} \ bytes}

Thus, the number of bits in the physical address is computed as:

= \mathbf{log_2 \{Physical-memory-size\}}

=\mathbf{log_2(2^{26})}}

= 26 bits

The number of entries in a page table = logical address space size/page size

The number of entries in a page table \mathbf{= \dfrac{2^{32}}{2^{12}}}

\mathbf{=2^{20}} entries

In a one-level paging scheme, the size of the table is:

= entire no. of page entries × page table size

= \mathbf{2^{20}\times 4 \ bytes}

= 4 MB

b.

suppose that this system supports up to 2^30 bytes of physical memory.

  • The size of the page table will be the same as 4 MB due to the fact that the number of entries, as well as, the page table entry size is the same.

Since the size of the page table surpasses that of a single page. A page cannot include a whole page table. Therefore, the page table must be broken into parts to fit onto numerous pages, and an additional level of the page table is required to access this page table.

  • This is called the Multi-Level Paging system.

Therefore, we can conclude that the number of bits in the physical address is 26 bits, the number of entries in a page table is \mathbf{2^{20}} entries, and the size of the page table in a one-level paging scheme is 4MB.
