What are the advantages and disadvantages of using a very large memory cell size, say, W = 64 instead of the standard size W = 8

? If each integer occupies one 64-bit memory cell and is stored using sign/magnitude notation, what are the largest (in terms of absolute value) positive and negative integers that can be stored? What if two cells are used to store integers?

Answer and Explanation:

  • The benefits of an large size memory cell is that you can store a lot bigger numbers (and all information is, eventually, numbers) in one cell, which by and large improves the speed and unwavering quality of information get to.  
  • The inconvenience is that you go through a bigger bit of whatever information stockpiling medium you are utilizing on each expression of information, and accordingly can store less information generally speaking.  
  • The biggest positive integer that could be put away in a framework utilizing sign/size documentation, with 64-piece cells is 263. On the off chance that two such cells were utilized to store numbers, the biggest whole number that could be put away by the framework is 2127.

In a certain computer program, two positive integers are added together, resulting in an overflow error. Which of the following
Airida [17]

The option that best explains why the error occurs is that The program can only use a fixed number of bits to represent integers; the computed sum is greater than the maximum representable value.

<h3>Can programs represent integers?</h3>

An integer value is known to be often listed out in the source code of a program in a way called a sequence of digits that is said to be optionally prefixed with + or −. Note that some programming languages do use other notations, like hexadecimal.

Computers are known to use a a fixed number of bits to show an integer. The most -used bit-lengths for integers are known to be 8-bit, 16-bit, 32-bit or 64-bit.

What changes should be made in OSI model(Open System Interconnection).
saveliy_v [14]

Answer:

Explanation:

When most non-technical people hear the term “seven layers”, they either think of the popular Super Bowl bean dip or they mistakenly think about the seven layers of Hell, courtesy of Dante’s Inferno (there are nine). For IT professionals, the seven layers refer to the Open Systems Interconnection (OSI) model, a conceptual framework that describes the functions of a networking or telecommunication system.

The model uses layers to help give a visual description of what is going on with a particular networking system. This can help network managers narrow down problems (Is it a physical issue or something with the application?), as well as computer programmers (when developing an application, which other layers does it need to work with?). Tech vendors selling new products will often refer to the OSI model to help customers understand which layer their products work with or whether it works “across the stack”.

Layer 7 - Application

To further our bean dip analogy, the Application Layer is the one at the top--it’s what most users see. In the OSI model, this is the layer that is the “closest to the end user”. It receives information directly from users and displays incoming data it to the user. Oddly enough, applications themselves do not reside at the application layer. Instead the layer facilitates communication through lower layers in order to establish connections with applications at the other end. Web browsers (Google Chrome, Firefox, Safari, etc.) TelNet, and FTP, are examples of communications  that rely  on Layer 7.

Layer 6 - Presentation

The Presentation Layer represents the area that is independent of data representation at the application layer. In general, it represents the preparation or translation of application format to network format, or from network formatting to application format. In other words, the layer “presents” data for the application or the network. A good example of this is encryption and decryption of data for secure transmission - this happens at Layer 6.

Anton [14]

The data that is transmitted in plain text is option D: cryptographic failure.

<h3>An established plain text only assault is what?</h3>

The known-plaintext attack (KPA) is a cryptanalysis assault type where the attacker has access to both the encrypted and plaintext versions of the data (also known as a crib) (ciphertext). These can be used to reveal additional hidden information, including code books and secret keys.

Therefore, Plaintext in the context of cryptography typically refers to unencrypted data that is being prepared for input into cryptographic techniques, typically encryption algorithms. Typically, unencrypted data transmission or storage falls under this category.
