Advantages of Laptop compared to Desktop

Portability is usually the first feature mentioned in any comparison of laptops versus desktop PCs. Portability means that a laptop can be used in many places—not only at home and at the office, but also during commuting and flights, in coffee shops, in lecture halls and libraries, at clients' location or at a meeting room, etc. The portability feature offers several distinct advantages:

• Getting more work done – Using a laptop in places where adesktop PC can't be used, and at times that would otherwise be wasted.For example, an office worker managing their e-mails during anhour-long commute by train, or a student doing his/her homework at theuniversity coffee shop during a break between lectures.

• Immediacy – Carrying a laptop means having instant access tovarious information, personal and work files. Immediacy allows bettercollaboration between coworkers or students, as a laptop can be flippedopen to present a problem or a solution anytime, anywhere.

• Up-to-date information – If a person has more than onedesktop PC, a problem of synchronization arises: changes made on onecomputer are not automatically propagated to the others. There are waysto resolve this problem, including physical transfer of updated files(using a USB flash memory stick or CDRs) or using synchronizationsoftware over the Internet. However, using a single laptop at bothlocations avoids the problem entirely, as the files exist in a singlelocation and are always up-to-date.

• Connectivity – A proliferation of Wi-Fi wireless networks and cellular broadband data services (HSDPA, EVDO and others) combined with a near-ubiquitous support by laptops
  means that a laptop can have easy Internet and local networkconnectivity while remaining mobile. Wi-Fi networks and laptop programsare especially widespread at university campuses.

Other advantages of laptops include:

• Size – Laptops are smaller than standard PCs. This isbeneficial when space is at a premium, for example in small apartmentsand student dorms. When not in use, a laptop can be closed and put away.

• Ease of Access - Most laptops have doors on the undersidethat allow the user to access the memory, hard drive and othercomponents, by simply flipping the laptop to access the doors. Fordesktops the user must usually access the backside of the computer,which is harder if it's in an area with little space.

• Low power consumption – Laptops are several times morepower-efficient than desktops. A typical laptop uses 20-90 W, comparedto 100-800 W for desktops. This could be particularly beneficial forbusinesses (which run hundreds of personal computers, multiplying thepotential savings) and homes where there is a computer running 24/7(such as a home media server, print server, etc.)

• Quiet – Laptops are often quieter than desktops, due both tothe components (quieter, slower 2.5-inch hard drives) and to less heatproduction leading to use of fewer and slower cooling fans.

• Battery – a charged laptop can run several hours in case ofa power outage and is not affected by short power interruptions andbrownouts. A desktop PC needs a UPSto handle short interruptions, brownouts and spikes; achievingon-battery time of more than 20–30 minutes for a desktop PC requires alarge and expensive UPS.[40]

• All-in-One - designed to be portable, laptops haveeverything integrated in to the chassis. For desktops (excludingall-in-ones) this is divided into the desktop, keyboard, mouse,display, and optional peripherals such as speakers, and a webcam. Thisleads to lots of wiring. It can also lead to massive power consumption.

• Extras - in comparison to low-end desktops, even low-endlaptops include features such as integrated Wi-Fi, and Express Cardslot, and a memory card reader.

Disadvantages

Compared to desktop PCs, laptops have disadvantages in the following fields:


Performance

While the performance of mainstream desktops and laptops is comparable, laptops are significantly more expensive than desktop PCs at the same or even lower performance level.[41] The upper limits of performance of laptops are a little bit lower, and "bleeding-edge" features usually appear first in desktops and only then, as the underlying technology matures, are adapted to laptops.

However, for Internet browsing and typical office applications, where the computer spends the majority of its time waiting for the next user input, even netbook-class laptops are generally fast enough.[42] Most higher-end laptops are sufficiently powerful for high-resolution movie playback, 3D gaming and video editing and encoding. However, laptops are disadvantaged when dealing with database, math, engineering, financial software, etc.

Some manufacturers work around this performance problem by using desktop CPUs for laptops[43].
Upgradeability

Upgradeability of laptops is very limited compared to desktops, which are thoroughly standardized. In general, hard drives and memory can be upgraded easily. Optical drives and internal expansion cards may be upgraded if they follow an industry standard, but all other internal components, including the CPU, motherboard and graphics, are not intended to be upgradeable.

The reasons for limited upgradeability are both technical and economic. There is no industry-wide standard form factor for laptops; each major laptop manufacturer pursues its own proprietary design and construction, with the result that laptops are difficult to upgrade and have high repair costs. With few exceptions, laptop components can rarely be swapped between laptops of competing manufacturers, or even between laptops from the different product-lines of the same manufacturer.

Some upgrades can be performed by adding external devices, either USB or in expansion card format such a PC Card: sound cards, network adapters, hard and optical drives, and numerous other peripherals are available, but these upgrades usually impair the laptop's portability, because they add cables and boxes to the setup and often have to be disconnected and reconnected when the laptop is moved.

Ergonomics and health
Because of their small and flat keyboard and trackpad pointing devices, prolonged use of laptops can cause repetitive strain injury.[44] Usage of separate, external ergonomic keyboards and pointing devices is recommended to prevent injury when working for long periods of time; they can be connected to a laptop easily by USB or via a docking station. Some health standards require ergonomic keyboards at workplaces.

The integrated screen often causes users to hunch over for a better view, which can cause neck or spinal injuries. A larger and higher-quality external screen can be connected to almost any laptop to alleviate that and to provide additional "screen estate" for more productive work.

A study by State University of New York researchers found that heat generated from laptops can raise the temperature of the scrotum when balancing the computer on one's lap, potentially putting sperm count at risk. The study, which included roughly two dozen men aged 21 to 35, found that the sitting position required to balance a laptop can raise scrotum temperature by as much as 2.1 °C (3.78 °F). Heat from the laptop itself can raise the temperature by another 0.7 °C (1.26 °F), bringing the potential total increase to 2.8 °C (5.04 °F). However, further research is needed to determine whether this directly affects sterility in men.[45]

A common practical solution to this problem is to place the laptop on a table or desk. Another solution is to obtain a cooling unit for the laptop, these units are usually USB powered consist of a hard thin plastic case housing 1, 2 or 3 cooling fans (the whole thing is designed to sit under a laptop) which results in the laptop remaining cool to the touch, and greatly reduces laptop heat buildup. There are several companies which make these coolers.

Heat from using a laptop on the lap can also cause skin discoloration on the thighs.[46]

Durability


Due to their portability, laptops are subject to more wear and physical damage than desktops. Components such as screen hinges, latches, power jacks and power cords deteriorate gradually due to ordinary use. A liquid spill onto the keyboard, a rather minor mishap with a desktop system, can damage the internals of a laptop and result in a costly repair. One study found that a laptop is 3 times more likely to break during the first year of use than a desktop.[47]

Original external components are expensive (a replacement AC adapter, for example, could cost 75 US$); other parts are inexpensive—a power jack can cost a few dollars—but their replacement may require extensive disassembly and reassembly of the laptop by a technician. Other inexpensive but fragile parts often cannot be purchased separate from larger more expensive components.[48] The repair costs of a failed motherboard or LCD panel may exceed the value of a used laptop.

Laptops rely on extremely compact cooling systems involving a fan and heat sink that can fail due to eventual clogging by accumulated airborne dust and debris. Most laptops do not have any sort of removable dust collection filter over the air intake for these cooling systems, resulting in a system that gradually runs hotter and louder as the years pass. Eventually the laptop starts to overheat even at idle load levels. This dust is usually stuck inside where casual cleaning and vacuuming cannot remove it. Instead, a complete disassembly is needed to clean the laptop.

Battery life of laptops is limited; the capacity drops with time, necessitating an eventual replacement after a few years. The battery is often easily replaceable, and one may replace it on purpose with a higher end model to achieve better battery life.

Security

Being valuable, common and portable, laptops are prized targets for theft. The cost of the stolen business or personal data and of the resulting problems (identity theft, credit card fraud, breach of privacy laws) can be many times the value of the stolen laptop itself. Therefore, both physical protection of laptops and the safeguarding of data contained on them are of the highest importance.

Most laptops have a Kensington security slot which is used to tether the computer to a desk or other immovable object with a security cable and lock. In addition to this, modern operating systems and third-party software offer disk encryption functionality that renders the data on the laptop's hard drive unreadable without a key or a passphrase.

Some laptops also now have additional security elements added by the consumer, including eye recognition software and fingerprint scanning components.

Comparison of deskops with laptops

Desktops have the advantage over laptops that the spare parts and extensions tend to be standardized, resulting in lower prices and greater availability. For example, the form factor of the motherboard is standardized, like the ATX form factor. Desktops have several standardized expansion slots, like Conventional PCI or PCI express, while laptops only tend to have one mini PCI slot and one PC card slot (or ExpressCard slot). This means that a desktop can be customized and upgraded to a greater extent than laptops. Procedures for (dis-)assembly of desktops tend to be simple and standardized to a great extent too. This tends not to be the case for laptops, though adding or replacing some parts, like the optical drive, rechargeable battery, hard disk, and adding an extra memory module is often quite simple.

Another advantage of desktop is, that (apart from environmental concerns) power consumption is not as critical as in laptop computers because the desktop is powered from the wall socket. Desktop computers also provides more space for heat to escape. The two large microprocessor manufacturers Intel and AMD develop special CPUs for mobile computers (i.e. laptops) that consume less power and lower heat, but with lower performance levels.

Aku suke ape yg ko paste ler.. ekot dr pnglman aku lah.. laptop n desktop mmg berbeza sgt tp kalau laptop kalau kaki gamer ssh kit ler sbb xdpt nak upgrade die punya graphic card. berbeza lak dgn desktop. tp nasihat aku, kalau nak beli laptop or desktop pastikan pilih yg bgs mcm processor, ram n etc. aku dulu xtau aper2 beli desktop yg low bajet ler. skrang dah addicted dgn game sims2 yg memerlukan pc yg power. skrang terpaksa lagi aku kumpol duit nak tukar graphic card lah, tambah ram to 4 gb lah n nak tukar processor at least dual core. itu suma memakan blnja hmpr seribu.

- Laptops are not for gamers
- Mudah hilang
- susah nak upgrade
- Manja, cerewet. Mudah rosak.
