There are bad times to buy a PC graphics card. Or any other component that uses GDDR5 or NAND memory. Chinese media Digitimes, with many confidants in the Chinese-made industry, today released a report stating that NVIDIA graphics cards will go up by 10% in these early days of September. The reason is the decision of Samsung and SK Hynix, its two suppliers of GDDR5 memory, to reduce its manufacturing to increase production of conventional RAM for business computers and mobile phones. The consequence of this is that the price of GDDR5 memory will increase by 30.8% in a matter of days, which will result in a 10% increase in the cost of NVIDIA graphics cards. According to the same report this rise will affect the entire range of NVIDIA, from the affordable GTX 1050 to the rest of the series 10: GTX 1060, 1070 and 1080. The problem is not unique to NVIDIA, as it affects all manufacturers that use all kinds of memories, especially the GDDR5 and NAND memories. To make them requires a number of precious metals that are meager and slow to process, so memory manufacturers can not meet the demand. What they are doing is giving priority to mobile memories, whose manufacturers order tens of millions of units, discriminating against smaller markets, such as PC graphics cards or the Nintendo Switch, which also has stock problems for the shortage of NAND memories. The market for PC graphics cards suffers another additional problem: the massive purchase of graphics cards to mine Bitcoins and other currencies, which is making it very difficult to find them in stock, or their prices are inflated. If you plan to buy an NVIDIA graphics card, now is the time to do it, before prices go up. In Amazon you have a lot of models of discounted NVIDIA cards.

Ever wish you could access some files on your work computer when you’re sitting in your home office? Need a report from your home computer that’s due in class? You can configure your computers to be accessible anywhere in the world, from virtually any other computer. There are a variety of ways to do this, including built-in tools, downloadable programs, and browser-based solutions. Read on after the jump to learn how. Method 1. Windows Remote Desktop (PC) 1. Enable Remote Desktop on the computer you want to access. On the Windows PC that you want to access, you will need to enable Remote Access so that other computers can connect to it. You can enable this on the Pro or Enterprise versions of XP, Vista, 7, and 8. This method requires that you be on the same network as the computer you want to access, either through the router or through a VPN. Press the Windows key + Pause to open the System menu. An alternative method is to click the Start menu, open up the Control Panel, click System and Security, then click System. Click the “Remote settings” link on the left side of the window. Check the “Allow remote connections to this computer” box. You can adjust some of the advanced options, such as length of time an invitation is good for, by clicking the “Advanced” button. 2. Add users. You will need to set which users can log in remotely on that machine. Click the “Select Users” button, and then click the Add button. Choose which users you would like to add. 3. Find the system name. When you connect to the computer, you will need to know the system name. You can find this by pressing Windows key + Pause and looking for the “Computer name” entry. 4. Disable Sleep mode. You will not be able to connect to a computer that is Sleeping or in Hibernate. Make sure to disable these if you want to connect remotely. Open the Control Panel and then select Power Options. You may have to switch views to see the icon. Click the “Change plan settings” link next to your active plan. Set Sleep and Hibernate to Never. Click the “Save changes” button when you are finished. 5. Connect to the computer. Log on to the computer that you want to use to connect to the remote computer. Click the Start menu and enter “remote desktop connection” into the Search field. Click it to open it. Enter in the system name of the computer that you want to connect to. Enter in the user name that you are connecting with. Click the “Show options” button to open the advanced options for your connection.

Computer hardware is the collection of physical parts of a computer system. This includes the computer case, monitor, keyboard, and mouse. It also includes all the parts inside the computer case, such as the hard disk drive, motherboard, video card, and many others. Computer hardware is what you can physically touch. Definitions A computer system consists of two major elements: hardware and software. Computer hardware is the collection of all the parts you can physically touch. Computer software, on the other hand, is not something you can touch. Software is a set of instructions for a computer to perform specific operations. You need both hardware and software for a computer system to work. Some hardware components are easy to recognize, such as the computer case, keyboard, and monitor. However, there are many different types of hardware components. In this lesson, you will learn how to recognize the different components and what they do. Types of Computers Before looking at the various components, it is useful to distinguish between two different types of computers: desktop computers and laptop computers. A desktop computer consists of a computer case and a separate monitor, keyboard, and mouse. As the name suggests, this type of computer is typically placed on a desk and is not very portable. Typical desktop computer with a separate computer case, monitor, keyboard, and mouse A laptop computer has the same components but integrated into a single, portable unit. Typical laptop computer with integrated hardware components While these two types of computers look quite different, they have the same general hardware components. Hardware Components Let's start with the computer case. This is the metal enclosure that contains many of the other hardware components. It comes in various shapes and sizes, but a typical tower model is between 15-25 inches high. Want to know what's inside? Okay, go get a screwdriver and let's open it up. Seriously, if you are really into computers, the best way to learn is to actually get hands-on. To save us some time, however, have a look at this desktop computer case. A computer enthusiast replaced the metal side panel with a transparent one, so we can have a look inside. Although that photo looks pretty cool, it is a bit hard to recognize the individual components, especially with all the connecting wires running through it. This figure shows a more schematic version of a desktop computer, which makes it easier to point out the essential hardware components. The various components of a computer case The computer case contains a power supply unit (#6) to convert general-purpose electricity to direct current for the other components. The most critical component is the motherboard (#2), a plastic board on which several essential components are mounted. This includes the central processing unit, or CPU, (#3), the main memory (#4), and expansions slots (#5) for other hardware components. The internal hard disk drive (#8) serves as the mass storage device for data files and software applications. An optical disk drive (#7) makes it possible to read from and write CDs and DVDs. Other hardware components typically found inside the computer case (but not shown in the figure) are a sound card, a video card, and a cooling mechanism, such as a fan. A computer system also needs input devices, such as a keyboard (#9) and a mouse (#10). To interact with a user, a computer system also needs a display device, such as a monitor (#1)
