A certain processor has a physical address of 36 bits (a byte addressable memory) and a single word consists of 4 bytes=32 bits. The cache unit is of size 256 Kbytes with line (block) size of 4 words (16 bytes). This cache has a 2-way set associative organization. The processor makes on the average, one instruction fetch and 0.45 data read/write from memory per instruction. For a block size of 4 words the measured miss rate is 1.5%. We want to investigate the possible benefits of increasing the block size to 8 words (32 Bytes). The estimated miss rate (based on simulation) for this larger block size is 1%. The cache miss penalty is equal to (6 cycles + # of words per block). Assuming that the cost of a reference that hits the cache is 1 cycle, what is the average memory access time for the two block sizes and which block size is the better choice based on the AMAT: 4 or 8 (words)? Round your answers to two decimal places. Assume that the given miss rate is same for both instruction and data. Select one: O a. 1.15 1.148 O b. 1.14 1.154 Oc 1.20 1.25 8 Od 1.20 1.254 Question 6 Not yet answ Points out o Rag ques
Answers
The main answer to the question is: The average memory access time (AMAT) for a block size of 4 words is 1.15 cycles, while for a block size of 8 words, it is 1.20 cycles.
To calculate the average memory access time (AMAT) for each block size, we need to consider the cache miss rate and the cache miss penalty.
For the block size of 4 words (16 bytes), the cache miss rate is given as 1.5%. This means that 1.5% of the instructions and data accesses result in cache misses. The cache miss penalty for this block size is calculated as 6 cycles + number of words per block, which is 6 + 4 = 10 cycles.
To calculate the AMAT, we multiply the cache miss rate by the cache miss penalty and add the cache hit time (1 cycle) to the result. So for a block size of 4 words, the AMAT is:
(1.5% * 10 cycles) + 1 cycle = 0.015 * 10 + 1 = 0.15 + 1 = 1.15 cycles.
For the block size of 8 words (32 bytes), the estimated miss rate is 1%. Applying the same calculation, the cache miss penalty for this block size is 6 + 8 = 14 cycles. Therefore, the AMAT for a block size of 8 words is:
(1% * 14 cycles) + 1 cycle = 0.01 * 14 + 1 = 0.14 + 1 = 1.20 cycles.
In conclusion, the average memory access time (AMAT) for a block size of 4 words is 1.15 cycles, while for a block size of 8 words, it is 1.20 cycles. Based on these results, the block size of 4 words would be the better choice since it has a slightly lower AMAT.

Answer:
1. Phishing is a cybercrime in which a target or targets are contacted by email, telephone or text message by someone posing as a legitimate institution to lure individuals into providing sensitive data such as personally identifiable information, banking and credit card details, and passwords.
2. Keyloggers are built for the act of keystroke logging — creating records of everything you type on a computer or mobile keyboard. These are used to quietly monitor your computer activity while you use your devices as normal.
3. Malware is intrusive software that is designed to damage and destroy computers and computer systems.
Explanation:
All of these can be used to steal data & passwords
Phishing, keylogging and malware are different ways of illegally getting hold of user data to be used for fraudulent activities.
Phishing is performed by impersonation, where users or customers of a particular organization or platform are contacted by emails, text or call requesting them to provide sensitive on behalf of the institution. Keylogging occurs when keystrokes of a user is being monitored without consent. The logged or captured keys can be used to log into the individual's information and retrieve sensitive data. Malware involves the use of infected files delivered over a network to carry out cyber attacks capable of capturing tons of data illegally. It is important to withhold sensitive information and contact service providers if any suspicious communication is received. Similarly, visiting unauthorized websites should be avoided and the use of firewalls on computer system should be adopted.Therefore, phishing, keylogging and malware are ways of perpetrating cyber crime.

d) 4Gb ocupados en el sistema operativo.
¿Cuánto espacio me sobre en el disco duro?
Answers
Answer:
Espacio a la izquierda = 858,8439008 Gb
Explanation:
Dados los siguientes datos;
Tamaño del disco duro = 1 Tb
Vídeos = 126 Gb
Archivos de Office = 1376 * 117 Kb = 160992 Kb
Mp3 = 3000 * 3.8 mb = 11400 Mb
Sistema operativo (OS) = 4 Gb
Conversión:
En primer lugar, convertiríamos el tamaño del archivo en kilobytes a megabytes.
1000 Kb = 1 Mb
160992 Kb = 160992/1000 = 160.992 Mb
Memoria total (Mb) = 11400 + 160,992
Memoria total (Mb) = 11560.992 Mb
A continuación, convertiríamos el tamaño del archivo en megabytes a gigabytes;
1000 Mb = 1 Gb
11560.992 Mb = 11560.992/1000 = 11.560992 Gb
Por último, sumaríamos todos los tamaños de archivo en gigabytes;
Espacio total (memoria) utilizado = 126 + 11.560992 + 4
Espacio total (memoria) utilizado = 141,560992 Gb
Conversión:
1000 Gb = 1 Tb
Espacio restante = tamaño del disco duro - memoria total utilizada
Espacio a la izquierda = 1000 - 141.560992
Espacio a la izquierda = 858,8439008 Gb

Answers
The correct syntax to define a generic class with multiple bounded parameters is:
`public class MyClass {...}`
This means that the generic type `T` must be a subclass of `Type1` and implement the interface `Type2`.
Java Generics was introduced to deal with type-safe objects. It makes the code stable.Java Generics methods and classes, enables programmer with a single method declaration, a set of related methods, a set of related types. Generics also provide compile-time type safety which allows programmers to catch invalid types at compile time. Generic means parameterized types. Using generics, the idea is to allow any data type to be it Integer, String, or any user-defined Datatype and it is possible to create classes that work with different data types.
A Generic class simply means that the items or functions in that class can be generalized with the parameter(example T) to specify that we can add any type as a parameter in place of T like Integer, Character, String, Double or any other user-defined type.
