6 Things to Consider When Buying a Laptop

Published

We’ll all need a laptop at some point in our lives and there are some broad guidelines you should keep in mind when buying a laptop so you can buy the right one.
Jumia Travel, the leading online travel agency, shares 6 of these broad guidelines to help you out.

The Screen
When buying a laptop, be sure to go for the laptop that gives you the best screen within your price range.
A good screen typically considers three things: resolution, viewing angles and size. Laptops with higher resolution screens are generally the best ones to choose.
For portability, smaller screens are better, but if you intend to use the laptop for entertainment and architectural or artistic functions, then a bigger screen is best.
Lastly, in terms of viewing angles, a laptop screen that touts IPS (in-plane switching) technology offers the widest viewing angles for the best user comfort.

Screen Quality
You should consider laptops that are comfortable to look at because you are likely to be looking at it for quite some time during the day.
Many laptops these days have touchscreens, but these touch screens tend to be glossy and glossy screens leads to reflections that negatively affect your eyes.
You should therefore try to avoid these glossy screens and maybe opt for laptops that aren’t touchscreen, but if you must buy one go for the ones that don’t have glossy screens.

RAM
Typically, more RAM is better. For a decent laptop experience, 4GB RAM can be considered, but 8GB RAM is recommended. If you intend to do a lot of video and photo editing, you can consider buying one with 16GB RAM.
More RAM allows for more applications to run at the same time, and for more data to be quickly accessible to the system at any one time. When buying a laptop, it’s always best to consider the ones with more RAM compared to others, within your favoured price range.

Keyboard Quality
It’s advisable to choose a laptop with a keyboard that’s comfortable for you, rather than one that packs in every key and forces you to start hunting for keys.
You should go for a keyboard with a comfortable layout with full sized keys and some space around the arrow keys.
The keys should have a sort of ‘snappy responsiveness’ and should be easy on your fingers.
When buying a laptop, it’s best to get a feel of the keyboard rather than ‘buying blind’ (asking someone to buy it for you or ordering online).

CPU
Intel’s Core-Based CPUs are one of the best to consider when buying a laptop. Core i3, Core i5, and Core i7 offer some of the best performance when it comes to multitasking and multimedia tasks.
However, for Core i7-based systems, though they offer the best performance for your laptop, the heat emitted from the base of the laptop tends to be a cause for concern if you plan to use the laptop for a long time.

Battery Life
Pay attention to the rating of the battery in Watt-hours (Wh) or milliamp-hours (mAh); typically the larger the figures, the longer the battery can last.

Nigeria CommunicationsWeek believes that technology makes life more exciting and helps improve the lives of people around Nigeria and indeed the world. So since 2007, we have devoted our energy to independent reportage of technology and how they affect lives.

By peter oluka

ESET, a leading global cybersecurity company, on Thursday launches Chrome Cleanup, a new scanner and cleaner for Google Chrome designed to help users browse the web safely and without interruption.

Chrome Cleanup will be available for all Google Chrome users running on Windows.

As cyber-attacks become more complex and difficult to spot, browsing the web can lead users to dangerous sites which can install malicious software onto devices.

Chrome Cleanup will alert Google Chrome users to potential threats when it detects unwanted software.

Google Chrome will then give users the option to remove the software. Chrome Cleanup operates in the background, without visibility or interruptions to the user. It deletes the software and notifies the user once the cleanup has been successfully completed.

“Using the internet should always be a smooth and safe experience for everyone,” said Juraj Malcho, chief technology officer at ESET. “For three decades, ESET has developed a number of security solutions that allow users to safely enjoy their technology and to mitigate a variety of cyber threats. Chrome Cleanup addresses unwanted software that can negatively influence a users’ experience on the internet.”

Chrome Cleanup is included in the latest version of Google Chrome. For more information about these tools, read Google’s blog post, here.

For 30 years, ESET® has been developing industry-leading IT security software and services for businesses and consumers worldwide.

With solutions ranging from endpoint and mobile security, to encryption and two-factor authentication, ESET’s high-performing, easy-to-use products give consumers and businesses the peace of mind to enjoy the full potential of their technology.

ESET unobtrusively protects and monitors 24/7, updating defenses in real-time to keep users safe and businesses running without interruption. Evolving threats require an evolving IT security company.

Backed by R&D centers worldwide, ESET becomes the first IT security company to earn 100 Virus Bulletin VB100awards, identifying every single “in-the-wild” malware without interruption since 2003.

A Buyer’s Market in the Global Economics of DDoS Attacks

Published

on

It’s a buyer’s market in the local property arena at the moment, according to certain industry experts.

 

This is largely as a result of the slower economy, which has seen a rise in the number of properties for sale.

 

But did you know that globally, it’s a buyer’s market as well when we look at the economics of Distributed Denial of Service (DDoS) attacks? The second, of course, is an underground market, largely regarded as a criminal one.

 

So said Bryan Hamman, Arbor Network’s territory manager for Sub-Saharan Africa.

 

Referring to recently released information from Arbor Networks, he said, “It is interesting to analyse the current economics in global DDoS attacks, which are attempts to make an online service unavailable by overwhelming it with traffic from multiple sources. Most people who are aware of DDoS attacks understand that there will be a perpetrator and a target.

 

“However, we’re now seeing a growing number of third-party providers of DDoS attacks as a service, who advertise their abilities online in order to either sell would-be attackers access to the tools needed to conduct a DDoS attack, or who perform the attack themselves on the customer’s behalf and provide reports afterwards.”

 

Hamman noted  that the fees of these underworld providers are lessening, due to rapidly expanding competition and the supply of readily available attack resources such as botnets. As a result, he says, the DDoS business is currently a buyer’s market.

 

Arbor reported that the prices for attack services, sometimes called “stressers” or “booters” vary widely, as do estimates of the total cost of an attack to the victim. But the economics are simple: DDoS attacks are becoming cheaper than ever for the perpetrator; are extremely lucrative for the attack service provider, and potentially financially devastating for the target.

 

Arbor noted that an increasing number of operators resemble legitimate service provider infrastructures with significant computing power, typically running their own botnet armies to unleash DDoS attacks. Perpetrators can essentially rent the providers’ botnets by the hour, day or week, or in some cases can buy a specific number of bots outright. The mechanics of transactions follow a classic web service model, meaning the perpetrator and the provider need never come in contact.

 

Providers that conduct attacks-as-a-service even post their services online, with tiered pricing reflecting the different types of attack that they offer. Prices are based on several factors. They can include the duration of the attack, the perceived value of the target, the country in which the attack takes place and/or the different methodologies employed.

 

In Arbor Networks 12th annual Worldwide Infrastructure Security Report, 59 percent of respondents estimated their downtime costs as being more than USD500/ minute in lost revenue (some ZAR6,700 per minute with the rand/dollar exchange rate on around ZAR13.50 to the dollar), with some indicating even higher losses. This also does not factor in the costs of repairing the damage, potential legal costs of settling with customers denied service, or reputational damage to the company’s brand.

 

Hamman concluded, “Here in South Africa, we may not yet face the overtness of DDoS operators advertising their services, as can be seen in the US. However, this does not mean that local companies shouldn’t be vigilant against DDoS attacks – protection is more vital than ever. A hybrid solution that combines on-premises and cloud-based protection is the industry best practice in DDoS defence. When you accept that DDoS attacks aren’t going away, and in fact are projected to escalate, it makes the best economic sense of all to make sure that you are adequately prepared against a DDoS attack.”
