Student advice to buy a computer if you are thinking in buying a computer and looking for advice in how to choose a good computer for you, you are in the indicated place. 1) The first step is to identify your neccesities, since there are a lot of options in the market you don't want to be ripped-off or not get what you expect. think about future situations that you could face as a student, for exmaple are you someone who is going to be in a very dynamic and changing context ? Are you planning on studying abroad ? in these cases you may consider to get a laptop, do you need extra battery life? Are you just aiming to investigate, write, do basic tasks but still have a good and felxible performance ? Basically, the advantage of a laptop is portability and for a PC the performance and endurance, almost always today's laptops are enough for the majority of engineering, health, bussineses, and so on students since technology has evolved and there are a variety of prices and options, but if you can and want a powerful, ergonomic, wider screen, long-lasting computer a PC would be the best option. 2) CPU's Cores, if you have a four core CPU is like having 4 computers in one, the more the cores the faster and expensive the computer becomes. For today's needs I'll recommend you 4GB of RAM, and you won't have problems. 3) compare models and prices,you might don't need 1000GB (1TB) space in hard disk if you are not a gamer, programmer or designer, if you read a lot it may be a good option to choose a wider or touchpad screen, read feedback, but as a rule, try to find what you need and don't get trapped by marketing if you don't want.

What preposition could substitue "with" in this sentence? *substitute, ': ) I've received this corrections, but I'm still not sure which preposition I should use instead of "with" or even better what sentence could express the same using the substantial word? Preposition: 'with' refers that having, possessing, or carrying something. e.g., "Employees look for something more than money. Incentivize them with more substantial rewards such as free days, vouchers or recognition." thanks

What does "wasn't his to take" and "sorry condition" means here? the story reinforces the theodicy of Zeus, who is wise and just, whilst Prometheus, in over reaching for knowledge that wasn't his to take, is to blame for humanity's sorry condition. Thanks : )

would you like to just join a conversation in Spanish? I think learning could be boost if through video conversations partners put themselves in situations like going for shopping, assist a classroom, etc. for example instead of buying a  ticket on the movies allow your partner to interact with the employee to buy it, it may be crazy but for me sounds cool, you have to deal with different real situation and moods
