Review Questions Chapter 4
1. To build your own computer (which I have done a couple time) at a minimum you need a central processing unit, a motherboard, random access memory, graphics processing unit (graphics card), hard drive or a solid-state drive (SSD), power supply unit, and a computer case.
2. A core is usually the basic computation unit of the CPU - it can run a single program context (or multiple ones if it supports hardware threads such as hyperthreading on Intel CPUs), maintaining the correct program state, registers, and correct execution order, and performing the operations through ALUs.
3. Hyper-threading allows the two logical CPU cores to share physical execution resources.
4. Supercomputers are built especially for assignments

Volatile memory is the RAM memory that is lost when your system is rebooted. Nonvolatile memory is the data that gets saved to your ROM memory. An example of Volatile is when a mac computers program is not responding and closes automatically its reopens your latest work rather than losing your work. An example of Nonvolatile is saving your work onto a flash drive or cd.
11. Main qualities to look for in an LCD are the size, brightness, contrast ratio, and pixel pitch.
12. Motherboard store data in a circuit.
13. DVD (digital video disc) come in a variety of recording options and can store 9.4 GB, more advanced DVDs has the capacity of 50GB. CD (compact disc) come in several types: CD-ROM, CD-R and CD-RW.
14. The footprint is the area that a computer occupies. A smaller footprint leaves more desk space for other devices.
15. Important features to consider before purchasing a PC is the power (speed, RAM capacity), expandability, ports, ergonomics, compatibility (with hardware and software), footprint, support, warranty, and cost.
16. If he were looking for a small a storage device I would recommend him to carry a tablet computer. It looks like a notebook computer without a keyboard and mouse. The user can handwrite text, which automatically turns into typed text, it is enthusiastically received among
When building a pc you need to keep a few things in mind such as budget and reasons to build it. Other things you need to keep in mind is what add-ons or things you want with it such as do you want ddr3 or ddr4. Would you need a type c port, usb 2.0 or 3.0. theres also storage do you want an hdd or an ssd. How many sata port do you want or need to run your drives and what watt power supply you need. And finally do you need a gpu or not and would you want to sli.
CPU (Central Processing Unit): processor is the brain of a computer and it does all the calculations of the computer.
1. What is the function of the /etc/hosts file? Which services can you use in place of or to supplement the hosts file?
Building a pc can be more reliable in many ways too. researching each specific part that is going to be in the build by looking at reviews for each one and the specs for each part. Reviews for each part of the computer that are bought prebuilt are not going to be displayed; The reviews for the whole computer are going to be displayed. Another reason building a computer is more reliable than buying one is getting the right price for each component that is going to be used. Companies will charge full price for every part and the price them
Now that I’ve told you about all the components that make up a computer it’s time to start deciding which to use. While deciding make sure you read everything because you’ll need to make sure everything is compatible. Now that you've bought all your components, it's time for the moment of truth: You're ready to actually put together the machine. Assembling your computer can seem daunting, but it's actually pretty easy. Here's what you need to do.
Multicore Cpus is a single computing component with two or more free actual central processing units (called "cores"), which are the units that read and execute program instructions. The directions are common CPU guidelines, for example, include, move information, and extension, however the numerous cores can run different guidelines in the meantime, expanding general pace for projects managable to parallel computing. Manufacturers regularly incorporate the cores onto a solitary coordinated circuit pass on (known as a chip multiprocessor
If the user of the PC is a hardcore gamer and he/she wants the games to play on high or ultra graphics settings without looking glitchy, or lagging out, then, the graphics card, RAM, and CPU are going to be the main focus of spending. Although if the user is just a casual gamer who doesn’t care about the look of the games he/she plays, and just really wants a computer for everyday browsing then the bare essentials are all that is needed. For, a hardcore build the base budget is in the range of twelve hundred to fifteen hundred dollars. The budget for a casual gaming PC is four hundred to six hundred dollars. One big rule when deciding a budget, NEVER try to save money on the power supply. The power supply is the heart of the PC, it gives the computer life. Without the power supply the other components would not be anything but metal and plastic.
A computer is a piece of equipment people use to do many things. People use computer for personal usage and for normal operations when running a business. Computers can range from a reasonable price to being an expensive piece of equipment. Building your very own computer should be based on a budget in which you will be able to afford and do the job you want it to do.
With new technology introduced every day it might be the time to upgrade to a better computer. Now the question is whether to invest in a pre-built computer or invest in time and money to build a custom computer. Even though there are many good pre-built computers being sold today, custom building a computer is more beneficial because it saves the user more money in the future, builders will have the ability to decide on what components go in the computer, and it avoids many of the preposterous tricks that manufacturers pull off. Since many pre-built computers lack the power and performance needed by gamers and photo editors, they often turn to building a custom computer themselves. Custom built computers will ensure the user cheap prices
When deciding to purchase a computer you need to make a decision. Do you want to build your own, or do you want to buy one that is already assembled? I will be explaining some pros and cons along with the risks of each choice and helping you decide which option is the best for you.
Will determine how many programs you can have open at the same time without slowing down the computer.
Why is it important to know this feature and the available options when choosing this device for multimedia purposes? (1 point) It is important to know this feature because this is the most common type of memory on a computer. By knowing the features and available options you can determine the best RAM for your computer needs. There are several different types, sizes and speed.
A portable storage device that can be attached to a desktop computer through a USB, Fire ware connection, or
The lodging is the piece of your PC that holds every one of the parts that make the PC work. In a desktop tower, the lodging does exclude a screen, console or mouse. A comprehensive PC houses both a screen and the segments that make the PC work, however does exclude a mouse or console. A portable workstation incorporates the screen, console, mouse (or mouse elective) and the segments that make the PC work
The CPU or central processing unit is what executes the programs. It is also where a majority of the money that is spent is going. Next, we are going to procure a motherboard which, in a sense, connects a majority of the other components together so that they can work together. RAM (random access memory) is next on the list. Whatever data is in operation at the time is going to be stored on the RAM so that it can be quickly accessed. The amount one gets should be decided on what is being planned on doing with it if just browsing two to four gigabytes if fine, but if editing or coding is planned eight or more should be purchased. A power supply is, as you can probably deduce, what powers the computer itself. Think about this: what happens if you try to start a car with no battery? Well, the same thing is going to happen to a computer should we have decided it was a bright idea not to get one or install it. Now, how are we going to plan to fit all the cool things that are going to be downloaded once we get the computer up and running? By getting a hard drive. It is where all of the crucial data is going to be stored. We are going to put all of this in whichever computer case that the user has chosen. These are all the parts necessary for an average browsing and minimal intensive program build.
