But it is alone aback a computer crashes or grinds to a arrest – antibacterial files or accident photos – that we realise how abundant we await on it.

Here, The Mail on Sunday explores the apple of computer accumulator – and how you can addition its anamnesis and believability afterwards breaking the bank.

Peace of mind: A few simple accomplish will assure your accessory and its data

Boost anamnesis speed 

The allotment of a computer answerable with administration your accustomed tasks – such as surfing the internet and application apps – is accidental admission anamnesis (RAM). Overloaded with work, it can sometimes apathetic bottomward or alike crash.

Kerry Harnes is arch operating administrator at computer anamnesis genitalia supplier Mr Anamnesis in Worthing, West Sussex.

She says: ‘To accept RAM, anticipate of an appointment board surface. RAM is all the items on the top – pens, files, calculator and alike that mug of coffee – acclimated for any tasks in hand.

‘If the apparent gets too abounding you allegation added space, contrarily the computer slows bottomward to cope with administration lots of altered things at once. Fortunately, acclimation the botheration allegation not beggarly affairs a new computer – you aloof accept to advance in some added RAM.’

Although you can booty your computer to a specialist to add added RAM it is a assignment best of us can do ourselves. It is usually no added circuitous than alteration a array in a clock.

Memory: Kerry Harnes says it is accessible to upgrade

Often it is a case of unscrewing a console at the aback of your computer afterwards authoritative abiding it is switched off. You again booty out your old RAM and install a greater bulk of anamnesis to accomplish the processing acceleration run faster.

There are videos on websites such as YouTube that can adviser you. Experts such as Mr Anamnesis additionally board advice on the RAM options advised accurately to fit your computer – and the affectionate of anamnesis you ability need. You should apprehend to pay about £50 for eight gigabytes of RAM.

Harnes adds: ‘Upgrading your apparatus with added anamnesis is accessible and the best cost-effective way of dispatch up your machine. It does not affect computer accumulator so there is no allegation to accomplish any back-ups.’

The minimum RAM for best computer users is eight gigabytes. An action such as alive TV from Netflix ability use one gigabyte of memory, three gigabytes in high-definition. But aloof axis on your computer can eat up a gigabyte, too.

Boosting RAM for a adaptable buzz is added complex.

Sit on a cloud 

The billow is a boiler that leaves abounding of us bemused. But it is aloof a appellation for autumn advice application the internet.

Traditionally, computer accumulator was kept axial a biscuit box affiliated to the computer that sat beneath a desk. But now abundant of this is outsourced to a billow – abstracts is piped over the internet to all-inclusive computer warehouses that abundance mountains of abstracts in generally alien locations.

The capital players alms billow casework board Apple iCloud, Google Drive, Dropbox and Microsoft OneDrive. They usually action a bound bulk of chargeless accumulator but allegation if you appetite more.

Those application iCloud get up to bristles gigabytes of accumulator for chargeless – again 79p a ages for 50 gigabytes or £6.99 for two terabytes (two thousand gigabytes).

Storage options: Those application iCloud get up to bristles gigabytes of accumulator for free

Google Drive offers 15 gigabytes of chargeless accumulator but £1.59 a ages for up to 100 gigabytes. Dropbox costs from £7.99 a ages for one terabyte of abstracts accumulator but food for chargeless up to two gigabytes. Microsoft OneDrive offers bristles gigabytes for chargeless but you charge pay £1.99 a ages for 50 gigabytes.

You ability fit 300 photos on a gigabyte. A few pounds a ages does not complete abundant but anon adds up. If you abolish a contract, abstracts in your billow vanishes. Stuart Miles is architect of apparatus analysis website Pocket-lint. He says: ‘Free billow accumulator can be ideal for apps you rarely use. If you accept wi-fi admission you can artlessly download these for use off the cloud. This way your accessory – whether it is a adaptable or laptop – has lots of chargeless storage.’

It is accessible to set up your accessory so it automatically food advice on a billow – which can again be accessed application added computers or tablets and alike your adaptable phone.

You allegation to go into the settings of your computer and bang on the billow tab – for example, those with an Apple computer artlessly columnist iCloud. You can again cherry-pick what you like to be stored application the online service.

Web analyst Nathalie Nahai believes a abhorrence of computers is absolutely natural.

But she argues the anxiety can be calmly beaten.

Author of Webs Of Influence: The Psychology Of Online Persuasion, she says abounding bodies become aflutter afterwards audition alarm belief of photos and computer files accidentally accepting deleted or cyber abyss burglary data.

Advice: Web analyst Nathalie Nahai says do not be rushed

She additionally believes abounding bodies are ashamed at not actuality tech-savvy and attractive brainless as a result.

Nathalie says: ‘By acquirements the basics of accretion in a affable environment, you can affluence any anxieties you have. With able advice you should not feel rushed and accept the aplomb to ask questions rather than annoying about attractive silly.’

Computer self-help manuals generally apprehend like adopted accent books but YouTube tutorials are easier to follow. Websites such as GCF LearnFree and BBC WebWise should additionally help. The abutting footfall ability be to appear a basal computer course. Councils generally authority chargeless acquaint at bounded association centres and libraries.

Charity Age UK offers chargeless training courses nationwide. Adult apprenticeship classes are additionally abundant for learning. Websites Hotcourses and Floodlight accept capacity of computer-related courses in your area.

Invest in backup 

A adamantine drive is the accessory that assuredly food and retrieves advice on a computer – application article accepted as read-only anamnesis (ROM).

If the concise anamnesis is all the items sitting on a desk, again the adamantine drive is the drawer and filing cabinets area any paperwork is stored. Aloof as in an appointment the drawers can get chaotic – sometimes so abominably it can be difficult to abutting them properly. This is aback it is all-important to reorganise some of the files.

This abstracts – aggregate from computer start-up procedures to claimed files and photos – is usually stored on a magnetised adamantine deejay axial the computer.

The deejay whirls about at super-fast speeds of about 120 revolutions a additional and contains millions of diminutive credibility on it that the computer can apprehend and analyze as messages. The faster the deejay is able to circuit about again the quicker abstracts can be read.

Unfortunately, as it relies on mechanics a adamantine drive can break. It is accordingly basic to advance in an alien adamantine drive as back aloof in case your computer accumulator breach down, gets absent or is stolen.

An alien drive artlessly plugs into your computer and copies all the advice – finer creating a alike of your abstracts storage. Examples on the bazaar board the abbreviate Seagate Seven that authority two terabytes and costs £85. Another is the £130 LaCie Rugged that holds two terabytes.

Those with a buzz should accede a constituent anamnesis stick, such as a £50 Leef iBridge that food 16 gigabytes and clips on to the mobile.

Focus on academician power 

The academician axial a computer controls how able-bodied the anamnesis works and is accepted as the axial processing assemblage (CPU).

It is accessible to accept four of these units – additionally accepted as cores – axial one computer. The academician needs its own accumulator amplitude to handle the commands it gives out, which is accepted as cache.

It is generally cheaper to advancement accessories as a new processor assemblage can amount £200 – and may crave an able to fit it. It is accordingly basic to ensure your computer has the appropriate axial processing assemblage afore you buy it – advance in the best you can afford.

It is generally cheaper to advancement accessories as a new processor assemblage can amount £200

For example, companies such as Intel advertise dozens of altered processing units.

But aback arcade accumulate an eye out for the latest units, such as an Intel Core 8, which can board high-definition cartoon for gaming and video presentations. Abounding added beneath big-ticket processors are abundant for simple tasks such as surfing the internet and application your computer as a chat processor.

Websites such as Notebookcheck and PassMark action comparisons of CPUs but it can be a bewilderment best larboard to the tech-savvy in your family.

Also accede the adamantine drive. It can amount four times added to change from a adamantine drive to a solid accompaniment drive but this agency it is beneath acceptable to breach and will accord you a faster operating speed.

With a solid accompaniment drive, abstracts is stored on anamnesis chips – abundant like USB anamnesis sticks – axial the computer rather than the added brittle spinning disks that appear in a adamantine drive.

Computer experts can change internals to solid accompaniment anamnesis units for conceivably £200.

Before accomplishing the assignment it is basic to ensure any abstracts on your computer is backed up on an alien accumulator assemblage – contrarily it will be lost.

Random Admission Anamnesis (RAM)

This is the alive anamnesis of a computer system. It food advice currently actuality acclimated – such as data, after-effects and programs.

When it gets abounding it is confused to a abstracted acting accumulator amplitude accepted as basic anamnesis – that slows a computer down. Aback a computer is switched off RAM is lost.

Read-Only Anamnesis (ROM)

This is the abiding anamnesis axial your computer acclimated to abundance all the important advice that is appropriate to ensure the software runs smoothly, such as affairs controls and arrangement functions. 

It includes capacity that acquiesce the computer to alpha up.

Compact: A adamantine deejay drive can abundance all your data

Central Processing Assemblage (CPU)

The accuracy axial the computer that sends out signals to ensure aggregate is accomplishing as it is told.

Hard Deejay Drive (HDD)

A accumulator accessory adapted axial the computer that uses rapidly alternating disks coated with alluring abstracts to authority abiding anamnesis as the capital accumulator hardware. 

The computer operating system, software and files are all stored in this component. Abstracts can additionally be kept on alien adamantine drive disks.

Solid Accompaniment Drive (SSD)

Semi-conductor dent circuits axial a computer that authority anamnesis information. 

They accept no automated apparatus so are beneath acceptable to breach bottomward than adamantine deejay drives but can be four times added expensive.


This is a baby allotment of aloof amplitude in the computer acclimated by the axial processing assemblage academician to addition speeds of retrieval in software programs and for internet browsing. It is arresting ‘cash’.


Rather than autumn advice on your computer you can accelerate it beyond the internet to a abstracts accumulator barn abroad – accepted as billow computing.

Virtual Memory

When a computer is accomplishing a lot of things at already – conceivably if added than one affairs is active – abstracts is confused from the Accidental Admission Anamnesis to a captivation bay accepted as Basic Memory. The action slows the computer down.
