In today's modern society, computers are an essential tool for any family because computers have become an important part of a family's day-to-day operations. Computers help with managing the household finances, writing academic papers, and connecting with friends through email and social media applications. Computers are also used in home-based businesses, for playing games, and shopping online. Whatever the need, a computer meets a variety of them because of the device's versatility, accessibility, and ease of use. It is therefore important to choose the right type of computer to ensure that the device is suitable for a family and its specific requirements.
eBay offers listings for a variety of PC desktops and all-in-ones to suit any family's specific needs. These PC desktops and all-in-ones usually come with essential hardware and software included. eBay offers popular brand names at affordable prices. When comparing PC desktops and all-in-ones, it is important to determine which device is best suited to a family's particular needs. It is also important to compare hardware, software, peripherals, and cost when shopping for either a PC desktop or an all-in-one.
Core Components of a Computer
Computers first became available for families in 1977 when the Apple II was introduced. In 1981, IBM introduced its first personal computer to the market. Since then, the personal computer has evolved and is now available in a whole host of shapes, sizes, and prices. The two main types of personal computers are the Apple devices and personal computers that run the Microsoft Windows operating system. These computers use operating systems that include Microsoft Windows, OS X, and Linux. OS X is used almost exclusively to run Apple computers. New versions of these operating systems are routinely issued. Besides the operating system, there are core components of a computer vital to its operation. These components include the computer case, motherboard, power supply, CPU or central processing unit, RAM or random access memory, drives, display adapters, and cables. These core components also determine how fast a computer operates.
The Computer Case
A computer case is where all the computer parts are housed. The type and size of the case is based on the type and size of the motherboard. A PC desktop case does not include the keyboard, monitor, or mouse inside the computer case. An all-in-one computer system does include the monitor and motherboard inside the computer case. It does not include the keyboard or mouse inside of the case.
The motherboard is the main circuit board for a computer. It connects all the components of a computer, both internal and external, including the CPU and memory. Some common types of motherboard include ATX and MicroATX. The motherboard must be compatible with the CPU. Motherboards may also vary according to to whether or not the components are removable and the number and nature of external device ports.
A computer's power supply allows the computer to operate. Portable computers use batteries and a power outlet. PC desktops and all-in-ones use a power outlet only. The computer's power supply is mounted to the inside of the computer case by cables connected to the motherboard or other components. It is then connected to the power outlet by a power connection cable mounted to the outside of the case.
CPU or Central Processing Unit
The CPU is a single chip processor that interprets every computer component code and translates it into a usable format for the specific operating system. How quickly and efficiently the hardware and software operate depends on the CPU. The two most common types of CPUs are Intel and AMD. These CPUs include 32-bit and 64-bit configurations.
RAM or Random Access Memory
The CPU requires RAM to operate quickly and efficiently. The RAM is a temporary storage location that holds information until it is processed or executed. A CPU that needs to run several programmes quickly at one time needs more RAM to execute these tasks. More RAM equates to a faster computer. It is important to determine the maximum amount and type of RAM that the CPU can adequately handle. The types of RAM include DRAM and SRAM.
A computer's drives include the hard drive and optical drive. The hard drive is a core component of a computer. The optical drive reads and writes to certain forms of media.
The hard drive stores the operating system information and software for a computer. It also stores information uploaded to the computer by the user, such as pictures, video, and personal documents. The hard drive is connected to the motherboard and permanently fixed inside the computer's case. Hard drive capacity is measured in megabytes, or MB.
An optical drive connects to the motherboard. It can be either be slot-loading optical drive or tray-loading drive. An optical drive uses light to read and write to media such as CDs, DVDs and Blu-ray discs.
A display adapter connects to the motherboard. Its purpose is to translate video signals. It can be a graphics card or a high-end, gaming adapter that displays 3D graphics at higher resolutions. High-end, display adapters consume a lot of power.
A computer's cables connect the computer's core components and peripherals together. The cables carry information back and forth between the core components and peripherals. They also supply power to the computer through the power supply.
Peripheral Components of a Computer
A computer's peripheral components are the components of a computer that are required for the computer to successfully interact with the user and other computers. They include ports, external hardware, and expansion slots. A family's specific needs can be fully addressed by adding additional peripherals to the family computer.
Most computer ports are directly connected to the motherboard. A cable is plugged into the port located on the outside of the computer. The different types of ports include USB, network, video, audio, and legacy ports.
External hardware is located on the outside of the computer's case. These include monitors, keyboards, and mice. All-in-ones house the CPU and monitor together in the computer case. Printers, speakers, webcams, headphones, and microphones are other types of external hardware.
Expansion slots allow a family to customise and add extra cards such as video and network cards to the motherboard. With the use of expansion slots, these cards can connect to additional printers and television receivers. It is important to remember that the type of card should match the type of expansion slot available on the motherboard.
Choosing a Family Computer
A family computer must meet the needs of each member of the family. The family's software requirements may include a word processing programme, a spreadsheet programme, and a money-management programme. Before selecting a family computer, it is important to determine exactly what type of computer is required and what device and software best suits the family's needs. PC desktops and all-in-ones are two types of computers used by families. Once a choice has been made, the buyer then needs to select an operating system, essential hardware and software, as well as peripherals. A family needs plenty of hard drive space and RAM to accommodate the chosen programmes. The computer also needs a good anti-virus and parental control programme to guard against computer viruses and prevent children from logging onto questionable websites. After the main needs have been addressed, the family can determine what add-ons should be included. Add-ons might include additional hard drives, video cards, and thumb drives. It is a good idea to check the computer's requirements for adding additional hardware and software before purchasing the machine.
PC desktops are computers that stay fixed to a specific location. They are not portable like laptops. The power supply is connected to a power outlet. Therefore, such a device consumes less power than a battery-operated computer. Although the word 'desktop' is included in the name, the actual computer case or tower case usually sits on the floor rather than the desk. The screen or monitor, keyboard, and mouse sits on the desktop. This allows more workspace on the desktop, unless the tower case is located on the desk. Most PC desktops also come with CD and DVD drives, CD burners, internal storage, and built-in modems.
PC desktops also use standardised parts that can be easily customised and upgraded. This allows competitive pricing amongst popular brands, resulting in lower prices for the buyer. Many brands also offer competitive packages that include printers and technical support within the overall price of the PC desktop. It is important to determine exactly how many add-ons the family requires and then compare costs and compare package options amongst manufacturers.
All-in-ones are a type of desktop computer that houses the core, internal, computer components, and the monitor in the same unit. The very first all-in-one computers were quite large and expensive. They were also used more within professional settings rather than in private households. With the introduction of the LCD monitor, the size of the all-in-ones decreased, allowing for more workspace. They are also a good fit for smaller work areas or desks, because they don't have as many cables as is the case with PC desktops. All-in-ones are not labelled as portable computers, although some all-in-ones have a handle on the top of the case, allowing for portability.
Although all-in-ones perform the same functions as a PC desktop, they are limited in their processing power, memory, and drive capabilities due to their smaller size. The all-in-ones use less power and generates less heat, but they also do not perform as well as PC desktops. In the past, all-in-ones could not be upgraded or customised like PC desktops, because their internal hardware was located within the same narrow space as the monitor. Now, the latest all-in-one model are using more standardised parts and advanced features, allowing for memory upgrades and lower prices for buyers.
The following table illustrates the basic differences between PC desktops and all-in-ones. These differences relate to space, performance, and cost.
Without tower on desk, more available desktop space
Better processing, memory, and drive performance
Lower costs with competitive packages and the use of standardised parts
Good for smaller workplaces
Lower processing power, memory, and drive performance
Limited upgrades, but newer models offer advanced features, resulting in their lower prices
The table above highlights the basic differences between PC desktops and all-in-ones. eBay offers a wide selection of computers, including PC desktops and all-in-ones, to suit any family's particular needs. The selection available on eBay fits any family's personal lifestyle and budget.

Computers are an essential part of everyday life, especially for a family. Children use word processing programmes to write academic papers for school. Adults use spreadsheet and money management programmes for business and finances. Most members of the family enjoy surfing the Internet, sending and receiving emails, playing games, listening to music, and uploading pictures. It is important to buy the right type of PC desktop or all-in-one to meet these different needs. A low-performing, low-speed computer is not a good fit for a large, tech savvy family.
