You want to use a terminal program to terminal into a cisco router. what protocol should i use

Inessa05 [86]

The router could be configured to accept telnet, ssh or http. For terminal use, I'd hope that ssh would work.

Some computer engineering students decided to revise the LC-3 for their senior project. KBSR and the DSR into one status register: the IOSR (the input/output status register). IOSR[15] is the keyboard device Ready bit and IOSR[14] is the display device Ready bit can be done in LC-3.

LC-4 is a poor design.

Explanation:

LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.

It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a theoretically viable target for a C compiler. The language is less complex than x86 assembly but has many features similar to those in more complex languages. These features make it useful for beginning instruction, so it is most often used to teach fundamentals of programming and computer architecture to computer science and computer engineering students.

The LC-3 specifies a word size of 16 bits for its registers and uses a 16-bit addressable memory with a 216-location address space. The register file contains eight registers, referred to by number as R0 through R7. All of the registers are general-purpose in that they may be freely used by any of the instructions that can write to the register file, but in some contexts (such as translating from C code to LC-3 assembly) some of the registers are used for special purposes.

When a character is typed:

Its ASCII code is placed in bits [7:0] of KBDR (bits [15:8] are always zero)
The “ready bit” (KBSR[15]) is set to one
Keyboard is disabled -- any typed characters will be ignored

When KBDR is read:

KBSR[15] is set to zero
Keyboard is enabled
Alternative implementation: buffering keyboard input

The producer thread will alternate between sleeping for a random period of time and inserting a random integer into the buffer.

Llana [10]

Answer:

// Producer Thread

void *producer(void *param) {

buffer_item item;

while (true) {

item = rand() % 100;

sem_wait(&empty);

pthread_mutex_lock(&mutex);

if (insert_item(item))

printf("Can't insert item\n");

else

printf("Producer %d: produced %d\n", *((int*)param), item);

pthread_mutex_unlock(&mutex);

sem_post(&full);

}

// Consumer Thread

void *consumer(void *param) {

while (true) {

buffer_item item = NULL;

if (in > 0)

item = buffer[in - 1];

sem_wait(&full);

pthread_mutex_lock(&mutex);

if (remove_item(&item))

printf("Can't remove item\n");

else

printf("Consumer %d: consumed %d\n", *((int*)param), item);

pthread_mutex_unlock(&mutex);

sem_post(&empty);

}

Explanation:

An outline of the producer and consumer threads appears as shown above.

A user is unable to install virtualization software on a Windows 8.1 computer. The user verified the host has sufficient RAM, pl

Phantasy [73]

Answer:

The correct option is C. The user does not have a valid product license key. Both the OS installed on the bare metal (that the host) and the client OS must have a valid license key.

Explanation:

There is a powerful virtualization tool is built into every copy of Microsoft Windows 8.x Pro and Windows 8.x Enterprise, Client Hyper-V.

This is the very same Type-1 hypervisor that runs virtualized enterprise workloads and comes with Microsoft Windows Server 2012 R2. The virtual machines you create on your desktop with Client Hyper-V are fully compatible with those server systems as well.

If you need to do testing as a software developer, or simply want an additional operating system(s) running on your computer, such as Linux, Hyper-V can be a great feature to have enabled on your PC.

To have the Hyper-V feature on your PC, you'll need to meet some basic requirements like your computer will need 4GB of RAM with a 64-bit processor that has Second Level Address Translation (SLAT).

Many PCs on the market have this feature, while many PC BIOSes have virtualization features turned on by default, your PC might not.

As BIOS menu layouts are not universal, you'll want to consult your PC BIOS documentation as to where the feature is located in your firmware setup and what it is called.

a. Windows 8.1 does not support Type 2 hypervisors.

This option is wrong. All 64-bit Windows 8.1 OS except for the Home version supports hypervisors type 2 as well as type 1

b. The motherboard does not support hardware-assisted virtualization.

Most of the PC that can run Windows 8.1 has visualization, all that is needed is to have it enabled if it was it enabled by default in the BIOS

c. The user does not have a valid product license key.

This is the correct answer. For you to successfully install visualization software on Windows 8.1, both the host OS and the client OS must have a valid product key

d. The system is incompatible with Type 1 hypervisors.

This option is wrong. The Windows 8.1 OS does not only support the installation of visualization software, it came with its hypervisor called Hyper-V.
