Video game designers with mobile software development expertise will be especially sought after as smart phones & tablets, such as the iPhone and iPad, continue to change how video games are accessed and played. Game designers will also benefit from growing public and private sector demand for intelligent simulation programs, e.g., military flight simulators.

       Network Administrator

Demand for network administrators will continue to rise as organizations invest in new systems and network technologies to increase productivity and gain a competitive advantage. The rapid adoption of tablets and smartphones – and “Bring your own device” (BYOD) policies – into corporate culture means more organizations will use the Internet to conduct business online, translating to increased job opportunities for network administrators and network managers who can help businesses securely utilize these emerging technologies to communicate with employees and customers.

     IT Security Specialist

Security will remain a top concern for IT executives and hiring managers as the frequency, scope and complexity of cyber attacks continues to escalate. IT executives interviewed in Computerworld’s 2012 IT forecast survey report actively seeking professionals with information security skills, but finding it difficult to locate good talent. This indicates an incredible opportunity for technology professionals to advance their security skills and credentials. Computer security skills in the greatest demand in 2012 and beyond include IT operations security, mobile device security, risk management, information assurance, network and cloud/virtualization security.

     Computer Systems Analyst

As organizations continue to increase their reliance on technology, computer systems analysts will be hired to architect new systems across all industries. Healthcare is a key field for systems analyst job growth, as aggressive government mandates and funding initiatives continue to drive rapid increases in electronic medical record (EMR) adoption, electronic-Rx services and other healthcare software projects that require the development of custom computer systems. The U.S. Department of Labor also predicts a 43% increase in systems analyst hiring at IT consulting firms, which translates to a huge amount of freelance and contract employment opportunities.

    Web Developer

Each year, a record number of businesses bring their offerings to the Internet. As the number of products and services available online continues to grow, web developers and designers will enjoy increased job opportunities. Proliferation of social media, social networking and other Web 2.0 communities will boost demand for web developers as businesses look to engage a new generation of customers and spur a competitive advantage in these rapidly growing platforms.

     Health Information Technician

Health care will produce more new computer jobs from 2012 through 2020 than any other single industry. Aggressive government mandates and funding incentives for hospitals and private health practices to adopt centralized electronic medical record (EMR) systems, is driving unprecedented hiring of health information technicians who are trained & certified in these new technologies. Health information technicians earn the lowest starting salary on this list, however the required education is the quickest (typically a 2-year degree program in Health IT), plus candidates learning now will be well-positioned for lucrative management positions as the health IT job market continues its rapid expansion.

     Technology Manager

Job growth for information technology managers is directly tied to the growth rates of the IT workers they supervise. Record-breaking growth in a wide range of technical career fields – including networking, mobile development, software engineering, databases and virtualization – will continue from 2013 through 2020 and beyond, in turn fueling demand for talented IT managers. Additional growth will be driven by increased focus on information security and the hiring of additional IT security personnel.

Computers & Softwares · Hardwares

Hardwares

Computer hardware is the collection of physical components that constitute a computer system. Computer hardware is the physical parts or components of a computer, such as monitor, keyboard, computer data storage, hard disk drive (HDD), graphic card, sound card, memory (RAM),motherboard, and so on, all of which are tangible physical objects.By contrast, software is instructions that can be stored and run by hardware.

Hardware is directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system.

Case

Main article: Computer case

The computer case is a plastic or metal enclosure that houses most of the components. Those found on desktop computers are usually small enough to fit under a desk; however, in recent years more compact designs have become more commonplace, such as the all-in-one style designs from Apple, namely the iMac. A case can be either big or small, but the form factor of motherboard for which it is designed matters more. Laptops are computers that usually come in a clamshell form factor; however, in more recent years, deviations from this form factor, such as laptops that have a detachable screen that become tablet computers in their own right, have started to emerge.

Power supply

Main article: Power supply unit (computer)

A power supply unit (PSU) converts alternating current (AC) electric power to low-voltage DC power for the internal components of the computer. Laptops are capable of running from a built-in battery, normally for a period of hours.

Mainboard

Main article: Motherboard

The motherboard is the main component of a computer. It is a board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots.

Components directly attached to or to part of the motherboard include:

  • The CPU (Central Processing Unit), which performs most of the calculations which enable a computer to function, and is sometimes referred to as the brain of the computer. It is usually cooled by a heatsink and fan, or water-cooling system. Most newer CPUs include an on-die Graphics Processing Unit (GPU). The clock speed of CPUs governs how fast it executes instructions, and is measured in GHz; typical values lie between 1 GHz and 5 GHz. Many modern computers have the option to overclock the CPU which enhances performance at the expense of greater thermal output and thus a need for improved cooling.
  • The chipset, which includes the north bridge, mediates communication between the CPU and the other components of the system, including main memory.
  • Random-Access Memory (RAM), which stores the code and data that are being actively accessed by the CPU. RAM usually comes on DIMMs in the sizes 2GB, 4GB, and 8GB, but can be much larger.
  • Read-Only Memory (ROM), which stores the BIOS that runs when the computer is powered on or otherwise begins execution, a process known as Bootstrapping, or “booting” or “booting up”. The BIOS (Basic Input Output System) includes boot firmware and power management firmware. Newer motherboards use Unified Extensible Firmware Interface (UEFI) instead of BIOS.
  • Buses that connect the CPU to various internal components and to expand cards for graphics and sound.
  • The CMOS battery, which powers the memory for date and time in the BIOS chip. This battery is generally a watch battery.
  • The video card (also known as the graphics card), which processes computer graphics. More powerful graphics cards are better suited to handle strenuous tasks, such as playing intensive video games.

Expansion cards

Main article: Expansion card

An expansion card in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus. Expansions cards can be used to obtain or expand on features not offered by the motherboard.

Storage devices

Main article: Computer data storage

A storage device is any computing hardware that is used for storing, porting and extracting data files and objects. It can hold and store information both temporarily and permanently, and can be internal or external to a computer, server or any similar computing device. It refers to computer components and recording media that retain digital data. Data storage is a core function and fundamental component of computers.

Fixed media

Data is stored by a computer using a variety of media. Hard disk drives are found in virtually all older computers, due to their high capacity and low cost, but solid-state drives are faster and more power efficient, although currently more expensive than hard drives, so are often found in more expensive computers. Some systems may use a disk array controller for greater performance or reliability.

Removable media

To transfer data between computers, a USB flash drive or optical disc may be used. Their usefulness depends on being readable by other systems; the majority of machines have an optical disk drive, and virtually all have a USB port.

Input and output peripherals

Main article: Peripheral

Input and output devices are typically housed externally to the main computer chassis. The following are either standard or very common to many computer systems.

Input

Input devices allow the user to enter information into the system, or control its operation. Most personal computers have a mouse and keyboard, but laptop systems typically use a touch pad instead of a mouse. Other input devices include webcams, microphones, joysticks, and image scanners.

Output device

Output devices display information in a human readable form. Such devices could include printers, speakers, monitors or a Braille embosser.
