7 Things to Look Out For When Buying A Computer

Azuka awoke with a blinding headache on Saturday. She held her throbbing skull in both hands and wondered what to do next. She wasn’t ill, but after six awful nights spent agonizing over how to avoid another big mistake, her nerve endings were on fire, screaming for relief.

She had paid dearly for buying her last laptop on a whim (she was swayed by the size and colour) but discovered a little too late that it was dysfunctional, out of date and slow.

Thousands of Naira later and after dozens of visits to repair shops, she had learnt her lesson, but now she had no idea where to start, apart from hopping into the first taxi and heading to the closest computer hardware store at Otigba.

Buying a new laptop computer can be both frustrating and expensive. Technology is growing with times, a sign of transformation.

Same can be said in the computer world, previously we used to be happy with just basic PC but now the game has changed with the people wanting more out of their PC.

Luckily, getting a new laptop need not result in moans before or after purchase, as there are a couple of things everyone, including dyed-in-the wool technophobes, can learn to look out for, without needing to present a systems engineering certificate.

According to Chuks, an ICT consultant at the computer village who has been in the business for over 10 years, one needs to read beneath the incomprehensible computer-geek gobbledegook available all over the internet and stick to brass tacks. Here are 7 things to look out for when buying a computer;

Size and Weight
Heavy laptops kill mobility. In 2011, computer processor maker Intel began pushing an Ultrabook category that focuses on lightweight systems — usually weighing about 3 pounds (1.3 kilograms) — to make use of its ultra-low voltage CPUs.

Ultrabooks do away with disc drives and focus on portability, long battery life. These laptops aren’t powerful enough for some users, and do away with a disc drive others find important, but they demonstrate a trend towards lightweight notebooks that are extremely portable.

The best way to get around the weight issue is to select a computer that makes weight and size a priority concern.

The downside however is that such computers are usually more expensive, which largely depends on what brand you drawn to.

Storage and Memory
Now, there are probably so many users who detest keeping an eye out for the memory size. It is however a necessary item on the purchase checklist if you want to avoid your computer freezing like Azuka’s which froze every three hours of every other day.

Storage space may not be a big concern for you — if you not a heavy user and don’t plan to load a computer up with gigabytes of music and video, an  SSD or small HDD will suit you just fine. Random access memory (RAM) is a different story.

Every piece of software running on a computer and the operating system itself (usually meaning Windows) stores data in RAM to function. The more RAM you have, the better.

Google your laptop to see if owners have found it easy to add additional RAM or swap out the hard drive. Either of those upgrades could give your laptop an extended lease on life sometime down the road, but some casings are much easier to open up than others.

Battery Life
The Battery Life is directly or indirectly the first need of any user. If the device’s battery system is of poor quality, then one will face many inevitable problems.

Laptop computing is all about mobility, and battery life is perhaps the most crucial consideration when picking a laptop that’s going to be used regularly on the go.

As laptops get slimmer and designers pay more attention to making them sleek and compact, more and more systems use integrated non-removable batteries.

The very first thing to do as a customer is, first ask about the Laptop’s battery life. So one should check and enquire about maximum support the Laptop’s battery will give, when being used in full capacity.

The size and power of a laptop affects how much room there is in the body for a battery (and how quickly it’s drained). It is in your best interest to find that size and weight sweet spot when purchasing a laptop.

Processors and Graphics
The simplest way to explain the processor is that it’s the brain of the machine. If you want a fast computer that boots up programs in a flash, completes tasks as soon as you start them, and doesn’t keep you waiting, then you want the strongest processor available — and who doesn’t? You just have to know what you’re looking at when you see a processor’s details.

The key to selecting processors is in the number of cores and the speed (labelled in GHz or Gigahertz) of the processor.

The speed of the chip will tell you how much data it can process in how much time, so the bigger the number, the better. (e.g. a single-core 2GHz processor is a lot slower than a four-core 2GHz processor).

Multiple cores can also help with multi-tasking, as each can be working on different tasks. If you don’t use a lot of programs at the same time, you may be content with just one or two cores and don’t need to spend a little extra money to snag a few more.

Make sure to ask how many cores are on the chip and what the clock speed is.

Two computers might both say they have an Intel i5 chip, but the number of models that go into the group are many, and their speeds and core counts can be leagues apart.

If you want to get into really nitty-gritty bits of the processor, you can compare a number of different CPUs to see if you’re getting the best one, and even see if you’re getting the best for your money.

So whether it be for work or play, the simple rule to remember when buying a computer is: the more/higher the processor, the better for you.

Ports and Expandability
Every computer user is familiar with the USB port, but not everyone is aware that a much faster update to the standard, USB 3.0, is slowly spreading through the computer industry.

USB 3.0 can be 10 times faster than its predecessor in real-world usage, delivering transfer speeds of up to 400 megabytes per second [source: EverythingUSB].

Even if you don’t own any USB 3.0 hardware right now, consider future proofing when buying a new laptop. You might be really thankful you have that USB 3.0 port down the road.

There are other ports to consider as well. Do you want HDMI to output video to a TV? Do you need an SD card slot for downloading digital camera photos to your laptop? Will you need an Ethernet port for Internet or will a laptop’s built-in Wi-Fi connection be enough?

Warranty
Being careful with your laptop is the best way to protect it. Picking a warranty isn’t an easy decision, either. If you’re clumsy and accident prone (or paranoid), opting for a long warranty will put your mind at ease.

But it will also cost you more, depending on the kind of coverage you choose. Total coverage packages for accidents are expensive, but you’ll be glad you have it if you accidentally step on your screen and break the LCD.

There are companies that offer free technical support for a year or less, whatever you are getting, start by trying to understand the terms and conditions stated in the warrant policy when deciding to purchase a computer. And there’s nothing wrong with going for the cheapest limited warranty you can — just don’t drop your new laptop!

Price
Everyone has a budget, and one should buy Laptops bearing same in mind. For instance, if your budget is 25, 000 and you are dreaming of a device which costs 50, 000, this is calling for avoidable debts.

So, in such case, you should concentrate on main functions needed for your use. In cheap price you can’t enjoy latest technology but can surely seek out functions which are basic and required one.

New systems usually come out shortly after Intel launches new processors. Look up review for laptops. See a model that was highly rated but came out nine months ago? A newer version will probably be along within a few months. Don’t buy a laptop months into its release cycle unless you’re shopping on a budget and spy a killer deal.

Buying a laptop isn’t always simple. After all, there are myriad factors to consider, but by arming yourself with knowledge, you can avoid Azuka’s migraine and enjoy easy clicking for much longer.

PwC Reveals AI Scaling Gap Slows Africa’s Digital Transformation

Published

on

Kindly share this post

African CEOs continue to trail their global counterparts in deploying artificial intelligence (AI) across business functions, as they remain stuck in experimental AI phases, finding it difficult to scale initiatives into enterprise-wide deployments.

This is one of the key findings of PwC’s 29th Global CEO Survey: Africa perspective. It found that more than 150 CEOs in Africa who participated in the survey demonstrate strong operational resilience and reinvention as they navigate currency fluctuations, political uncertainty, infrastructure constraints and supply chain disruptions.

It highlights a slower pace of digital transformation that could limit long-term competitiveness in Africa. While awareness and early adoption of AI are growing, enterprise-wide deployment remains limited, according to the survey.

The survey was conducted from 30 September to 10 November 2025 and surveyed 4 454 CEOs across 95 countries, including Africa.

Skills shortages, fragmented data governance, underdeveloped cloud infrastructure and risk-averse investment strategies are preventing African organisations from moving beyond pilot projects into full-scale AI-driven transformation, it finds.

“AI adoption in Africa is real, but scaling it across the enterprise remains a challenge,” says Christiaan Nel, AI Africa leader at PwC South Africa. “Caution must be balanced with urgency − those investing modestly today risk falling behind competitors scaling rapidly.”

 Finding their way

Despite these challenges, African CEOs demonstrate strong operational resilience. The survey shows that 81% are optimistic about improving economic conditions, well above the global average of 65%, while 47% are confident about revenue growth over the next year.

The survey underscores that AI adoption highlights a broader reinvention gap. Only 41% of CEOs have clear AI roadmaps, and 37% formalised responsible AI processes. Skills availability remains a major barrier, with just 37% confident in sourcing and retaining talent for AI initiatives.

PwC research shows that when AI is implemented effectively, African companies experience tangible benefits: 56% report increased employee productivity, 53% gain executive time, 23% see revenue growth, and 25% achieve cost reductions. This confirms that AI can drive efficiency and transformation, but only if infrastructure, governance and investment keep pace, notes the study.

Vikas Sharma, Africa cyber leader at PwC Mauritius, explains: “The challenge is structural. Fragmented cloud environments, unclear data governance and underdeveloped cyber security make scaling AI difficult. Without these foundations, AI initiatives remain tactical rather than transformational.”

Beyond AI, CEOs are using technology to reinvent products, reach new customers and modernise operations. PwC highlights that cloud, analytics and digital frameworks are essential enablers for enterprise-wide AI, helping leaders move from experimentation to transformation.

Importantly, African organisations are using technology to augment rather than replace employees, maintaining workforce stability while improving productivity, it states.

Ambition versus execution

Although 55% of African CEOs consider innovation critical to strategy, only 13% are willing to take high risks in innovation projects.

Underlying capabilities reveal the challenge: just 16% operate dedicated innovation centres, 25% have processes to stop underperforming research and development, and 29% rapidly test ideas with customers.

Lullu Krugel, chief economist and ESG leader at PwC South Africa, adds: “The leaders who build enduring businesses protect their core while creating the future. Operational strength alone is not enough; transformation must be bolder.”

Investment restraint is evident: 59% of respondents report little to no change in IT spending, and only 8% are willing to make large investments despite geopolitical uncertainty. Confidence in acquisitions is lower than the global average, with 40% planning growth through acquisition, compared to 46% globally.

Yet diversification offers a competitive-edge. Nearly half of African CEOs have entered new sectors through services and product offerings in the past five years, generating 24% of revenue from these ventures. Technology leads planned expansion efforts at 17%, followed by real estate, retail and transport/logistics.

PwC concludes that Africa’s CEOs have the ambition and resilience but must move from operational excellence to strategic reinvention. This requires embracing risk as a catalyst for transformation, strengthening digital infrastructure, investing in change leadership and aligning AI adoption with enterprise-wide strategy.

Hannelie Gilmour, consulting and transformation platform leader at PwC South Africa, concludes: “Africa is uniquely positioned to leapfrog global peers. Tomorrow’s stability comes from today’s innovation. CEOs who act decisively will shape the continent’s next chapter.”

Firm Reviews the Evolution of Phishing Threats in 2025

Published

on

A new Kaspersky review reveals how cybercriminals revived and refined phishing techniques to target individuals and businesses in 2025, including calendar-based attacks, voice message deceptions and sophisticated multi-factor authentication (MFA) bypass schemes.

The findings emphasise the critical need for user vigilance, employee training and advanced email protection solutions to counter these persistent threats moving forward.

Calendar-based phishing targets office workers

A tactic originally from the late 2010s, calendar-based phishing, has reemerged with a focus on B2B environments. Attackers send emails with calendar event invitations, often containing no body text, hiding malicious links in the event description.

When opened, the event auto-adds to the user’s calendar, with reminders urging them to click links leading to fake login pages, such as those mimicking Microsoft.

Previously aimed at Google Calendar users in mass campaigns, this method now targets office employees. Organisations should conduct regular phishing awareness training, such as simulated attack workshops, to teach employees to verify unexpected calendar invites.

Voice message phishing with CAPTCHA evasion

Phishers are deploying minimalist emails posing as voice message notifications, containing sparse text and a link to a basic landing page. Clicking the link triggers a chain of CAPTCHA verifications to bypass security bots, ultimately directing users to a fraudulent Google login page that validates email addresses and captures credentials.

This multi-layered deception highlights the need for employee training programmes, such as interactive modules on recognising suspicious links and advanced email server protection solutions like Kaspersky SecureMail, which detect and block such covert tactics.

MFA bypass via fake cloud service logins

These sophisticated phishing campaigns are targeting multi-factor authentication (MFA) by mimicking services like pCloud (a cloud storage provider that offers encrypted file storage, sharing and backup services).

These emails, disguised as neutral support follow-ups, lead to fake login pages on lookalike domains (e.g., pcloud.online). The pages interact with the real pCloud service via API, validating emails and prompting for OTP codes and passwords, granting attackers account access upon successful login.

To counter this, organisations should implement mandatory cybersecurity training and deploy email security solutions like Kaspersky Security for Mail Servers, which flags fraudulent domains and API-driven attacks.

“With phishing schemes growing more deceptive, Kaspersky urges users to treat unusual email attachments, like password-protected PDFs or QR codes, with caution and verify website URLs before entering any credentials.

“Organisations should adopt comprehensive training programmes, which includes real-world simulations and best practices for spotting phishing attempts. Additionally, deploying robust email server protection solutions ensures real-time detection and blocking of advanced phishing tactics,” comments Roman Dedenok, Anti-Spam Expert at Kaspersky.

Nigerian Data Protection Commission (NDPC), has expressed its commitment to balance information around data privacy and protection.

NDPC Commits to Balancing Data Privacy, Protection Information

Dr. Vincent Olatunji, national commissioner, NDPC, stated this in Abuja, at the National Data Privacy Summit with the theme, “Privacy in the Era of Emerging Technologies,” organised by the commission.

Olatunji said the NDPC, at the moment, was looking at balancing information around data privacy and protection.

“What we are doing is just to look at how to balance information around privacy and protection, which is really important, because as we are innovating, at the same time, we have to consider issues around privacy and protection,” he stated.

He added that the commission has been very bold in taking risks that would bring about growth.

“Our starting point is growing at a very alarming rate, and we are not afraid of anything. We can take risks. And that is why a lot is happening in Nigeria, and this is the level of clarity,” he explained.

In his address, Dr. Aminu Maida, executive vice chairman (EVC) of the Nigerian Communications Commission (NCC),  stated that Internet of Things holds promise for Nigeria’s economy.

The EVC, who was represented by Abraham Oshadami, executive commissioner, Technical Services (ECTS), noted that, “in an era in which digital assets, Internet of Things, future digital computing and other transformative technologies are key, and both a cornerstone of building trust for the adoption and a prerequisite for sustainable progress.

“Emerging technologies hold immense promise for Nigeria’s grand economy, but they also introduce complex risks to personal and individual rights.

“So, balancing innovation through post-ethical safeguards and public trust is the first step to ensuring that global digital advancement benefits all Nigerians without compromising their privacy or their security,” he added.

“As we just heard from the Nigeria Police, telecom operators have a vast amount of sensitive historical information daily, including connectivity apps and collaboration on privacy, security, and number protection, both to their and their inheritors,” he said.

Dr. Bako Shurkuk, commissioner for Science, Technology and Innovation, Plateau State, who represented Caleb Mutfwang, Governor of Plateau State, said, emerging technologies can be harnessed to attain sustainable growth.
