How to Revamp Your Old, Cheap Computers

old computer

Over time, a computer will certainly become slower and perform poorly. This is certainly the case with cheap Dell computers. There are a number of different options when it comes to revamping old, cheap computers or deciding to find affordable computers for sale.

Updating
Older, cheap computers are often not able to handle the programs and files that are popular today. This causes a computer to slow down and perform poorly. In these instances, you may be surprised to find that by replacing or adding RAM to cheap computers can greatly improve things. A computer uses this memory to efficiently and effectively open and run the programs. Before searching for computers for sale such as the Dell Optiplex, this upgrade may breathe new life into the machine.

Cleaning Up
Over time, it is very easy and very common for cheap computers to get bogged down with lots of unnecessary programs as well as viruses and malware. Purchasing a new Dell OptiPlex is a way to negate this problem, but there are a few things that can be done before looking at the computers for sale.

By looking through all of the installed programs on the computer, you may be able to determine that certain things can be removed. If a program is no longer needed or used, it may be taking up valuable space on the hard drive.

There are many free and inexpensive antivirus and cleaning programs that can be simply installed onto cheap computers to clean them up. New computers for sale will generally come with a trial version of such software, but over time these expire and become outdated. By downloading and running these programs, the computer can be significantly cleaned up and may perform much better.

Computers for Sale
If it is determined that the computer cannot be salvaged or improved, you may need to seek out computers for sale. There are many options to choose from, and it can often be quite confusing if you do not know what to look for. The needs of the individual and the family should dictate the type of computer that is purchased. The Dell Optiplex series is a great range of desktop computers that are reliable as well as affordable. If it is finally time to upgrade your old computer, be sure to look first at the Dell Optiplex series.

Mac or Windows?

The ongoing battle of Mac vs Windows has been discussed for so many years, its an endless war between both systems. For many of us buyers, deciding whether to buy a Mac or Windows can be a very tough decision. Both system has its own advantages and disadvantages, so at the end of the day it may very well depends on your preferences on which you think is better for you. A lot of people’s choices does have to do with people’s influences and the media, so it’s important to do your own research and find out what works best for you. Let’s find out more in the following related articles.

Windows vs. Mac: Who Is The Winner?

Wait. What? Is that whole ‘Windows vs. Mac’ thing still going on? I thought that was settled 20 years ago. Steve Jobs himself said the desktop wars were over. Microsoft won. Is that battle still raging?

Yes, but it depends. Somehow the battle rages on in Matt Weinberger’s head on a very slow news day at the Business Insider Fake News Emporium. You see, Windows vs. the Mac is just exactly like Android vs. the iPhone. They’re false equivalencies but they make for great fodder during the aforementioned slow news days when nothing else matter except presidential tweets.

False equivalencies? Uh, yeah. Windows is an operating system. The Mac is a personal computer. That’s much like Android is an operating system. The iPhone is a smartphone. But people love a good comparison so let’s take a stroll down Business Insider’s ever imaginary yellow brick road to see why the tide is turning in Microsoft’s favor.

Which is Better, Mac or Windows?

Apple’s software has long been heralded as a better designed and easier to use system, with Windows being a less glossy but more adaptable option. Is there still truth to that oversimplification? Well, both systems are now so feature-congruent that the old rivalry doesn’t exactly hold true anymore. Both systems offer all the major features you’d expect of a modern operating system and, for daily usage, most people would be fine with either.

It’s in the details, though, where they differ. If you’re a gamer, you’ll probably want to stick with Windows particularly because you can adapt your own hardware to suit your needs. That might mean building a soup-ed system from scratch or just upgrading your graphics card.

Both macOS and Windows 10 have voice assistants, with Cortana on Windows and Siri on Mac. While they can be helpful when you just want to check the weather or search for something online, we’ve found that we don’t use them all that much. It feels a little less natural than using voice assistants on a phone and laptop microphones don’t always work that well. (read more at lifehacker.com)

Why I left Mac for Windows: Apple has given up

If you ask anyone who knows me, I’m probably the biggest Apple fan they know. Ask for a suggestion of what computer to get, and I’ll almost certainly either tell you the MacBook Pro, or to wait, because Apple is about to update its hardware finally.

But recently, I realized I’d gotten tired of Apple’s attitude toward the desktop. The progress in macOS land has basically been dead since Yosemite, two years ago, and Apple’s updates to the platform have been incredibly small. I’m a developer, and it seems to me Apple doesn’t pay any attention to its software or care about the hundreds of thousands of developers that have embraced the Mac as their go-to platform.

Take a look at Sierra: the only feature of note is Siri, which is half-baked as it is, and the things that did get ported over from iOS are half-done too. On the developer side? Nothing, unless you use XCode — the same story it’s been for years. (read more at businessinsider.com)

The New Dell XPS 15 (2017) Reviews

Image by dell.com

It’s 2017 and Dell has just unleashed one of their best laptop of the year. So what is the hype about the Dell XPS 15? First off, this laptop has been comparable to the Macbook Touch Bar, although it’s not to say the Dell XPS is better than the new MacBook Pro, it certainly does have some advantages over the MacBook Pro. One of the most attractive features about the Dell XPS 15 is that it has an excellent battery life and a stunning high-resolution graphics. To find out more, we’ve gathered the following reviews about the new Dell XPS 15. Let’s take a look at the reviews below.

Dell XPS 15 (2017) Review

You want toned, tight, and thin bezels? Dell’s got the bezels. The ones at the top and sides of the screen of the XPS 15 measure just 5.7mm (0.22 inch), helping Dell deliver what it calls the world’s smallest 15.6-inch laptop, with a footprint (9.3 by 14.1 by 0.66 inches) closer to that of many 14-inch models. The family resemblance to the famously petite XPS 13 is obvious, right down to the Webcam being mounted below instead of above the display. (Nice nostrils you have there. Is that a double chin?)

At 4.5 pounds, the touch-screen XPS 15 is fairly light for its class (and non-touch models are half a pound lighter). It’s noticeable in a briefcase, but well-balanced and easy to carry outside of one.

Lift the lid, and you’ll see plenty of carbon fiber below and on either side of the keyboard—the XPS is one of the few 15.6-inch laptops without a numeric keypad, so there’s ample unused space—along with a generous touch pad south of the space bar and a power button in the top right corner.

Dell XPS 15 (2017) To Feature High-End Specs; Next MacBook Pro Killer?

Dell may very well be planning to take on MacBook Pro with their next offering. The high-end 2017 Dell XPS 15 has everything in it to take on MacBook Pro head on. It isn’t necessarily the world’s thinnest, lightest or the most powerful laptop but it has what it takes to make it the MacBook Pro killer.

From design to performance, Dell XPS 15 (2017) has got it all. Featuring a body built with a premium-looking aluminium chassis and carbon-fibre that surrounds the keyboard, the laptop features USB 3.0, USB-C with thunderbolt, HDMI 2 port and charging port. At 2kg, the laptop is probably a bit too heavy but considering the powerful features it comes with, this one’s definitely worth the buy. Packed with a powerful quad-core processor, 15-inch screen and an SD card reader, the Dell XPS 15 (2017) is being touted as the MacBook Pro killer.

What sets apart Dell XPS 15 (2017) and makes it eligible to take the MacBook Pro head on is its stunning Infinity Edge screen – the 15-inch screen looks very vivid and will give Dell an edge over MacBook Pro. It comes in two screen variants – 1080p and 4K. The vivid screen covers 99.9 percent of the sRGB colour standard, 96.9 percent of Adobe RGB and 91.4 percent of DCI P3, making games and videos look stunning. What’s more, the 4K variant has touchscreen capability. (read more at mobipicker.com)

How a Laptop Computer Works

How a Laptop Computer Works

What is a Laptop? A laptop is a personal computer (PC) produced for providing mobility and portability to users. Laptops are designed to work on small desk space or a user’s lap, hence the name. Laptops combine the majority of desktop computer function and components. Laptops feature the abilities to display information, input data, control a mouse, create sound and attach to networks including the Internet. Where desktop computers function on AC electrical current, laptops feature rechargeable batteries which are powered through an AC adapter.

While laptops were once far behind desktops in power, they are now comparable, if not surpassing, in computing ability.Laptop devices are normally 15-by-11 inches in diameter and weigh in the area of 5 to 10 pounds. They use hinge design to open the display screen to access the monitor and keyboard for the user. Newer monitors are incorporating touchscreen technology as well.

How a Laptop Works

A laptop works in a very similar manner to a desktop computer. Laptops use the same ideology in hardware but have differences in the size and connectivity of the components. Desktop computers use motherboards, or centralized circuit boards, to connect other components such as memory, hard drive, optical drives and video cards. Laptops, due to their compact size, must use a system board that has ports that take responsibilities shared by expansion cards in desktops. Laptop system boards will have built-in connections for video, sound and network connectivity. Components that are not part of the system board must be smaller, designed to create less heat and use less energy.

HD-Technology-Wallpaper

Memory chips for RAM function the same as their desktop versions except they are smaller and limited in capacity by physical size. Hard drives are smaller and thinner and connect directly to the system board rather than through a data cable as in desktops. The other major differences are the keyboard and monitor. The keyboard is built into the laptop’s system and is not interchangeable. Data entered from the user goes directly into the system via a system board attachment. The same can be said for the monitor, which receives display information through cables in the hinges of the laptop case.

Netbooks

While laptops are replacing desktop computers with their portability, netbooks are doing the same to laptops. Netbooks are small, light computers measuring less than 10 inches and weighing the area of 3 pounds. Netbooks normally do not use internal components such as CD-ROMs, floppy drives or DVD-drives and function mainly for Internet connectivity and mobility.

What Is a Computer Network Interface Card?

What Is a Computer Network Interface Card?

A network interface card, or NIC, is the hardware component that enables a computer to communicate on a network. NICs act as a computer’s physical interface and hardware address within a network. Without a NIC installed, it is impossible for a computer to communicate on a local area network or the internet.

MAC Address

nic

All NICs have a unique physical address assigned to them called a MAC address. This address consists of 6 pairs of hexadecimal characters separated by dashes or colons (i.e. 01:23:45:67:89:ab.) This address is used to identify the card on the local network and assist in the efficient delivery of data from one location to the next. Generally, a MAC address is burned into the card on ROM and cannot be changed.

Varieties

Network interface cards are designed to use a standardized interface to the transition media. In other words, they only work with specific connectors or wireless standards. Some common examples of these technologies include the ISDN, DSL, Ethernet, Bluetooth and Wi-Fi standards. In order for a local network to function properly, the NIC must utilize the same technology as the other devices on the network.

Standards

The two most common network standards are Ethernet (via RJ45 connector) and Wi-Fi (via 802.11 wireless standards.) An Ethernet NIC will generally have one RJ45 input that can be used to connect a computer to a router or modem with a Cat-5 cable. A Wi-Fi NIC will generally use a small antenna to transmit and receive the 802.11g or n wireless standard signal. There are many less common variations and alternatives to these technologies, but Ethernet and Wi-Fi are by far the most broadly available.

Hardware Interface

internet-wallpaper-17

NICs can interface with a computer in several different ways. Internal NICs can be built directly on the motherboard or installed in a PCI slot. External NICs will often use a USB or Firewire interface. Some are built specifically for use with laptops and can fit in a free PCMCIA card slot.

Considerations

When choosing a NIC the most important factor to consider is the technology utilized by the network it will be interfacing with. If the NIC operates using incompatible cabling or technology it will be unable to communicate on a network. If the network in question is wireless, it is important to make sure the standard of the wireless router is the same as the wireless standard used by the NIC. Other factors that influence the performance of a Wi-Fi NIC are distance from router, radio interference and matching channels of all devices on the network.
