desktop computersdesktop computersA desktop computer is an electronic machine computer that converts raw data into meaningful information, made for use on a desk in an office or home and is distinguished from portable computers such as laptops or PDAs. Desktop computers are also known as microcomputers. There are four types of desktop computers: home computers, or personal computers; workstations, Internet servers, and special communications computers. Desktops are currently the most affordable computers and ubiquitous in businesses, schools, and households; they are used for performing office tasks, organizing digital photos, video editing, and Internet access. Nearly all desktop computers are modular, with components that can easily be replaced or upgraded. Desktop computers come in a variety of case styles ranging from large vertical towers to small form factor models that can be tucked behind an LCD monitor. desktop computers Hardware An exploded view of a modern desktop computer: Display Motherboard CPU (Microprocessor) Primary storage (RAM) Expansion cards Power supply Optical disc drive (ODD) Secondary storage (HDD) Keyboard Mouse The hardware in a desktop computer is modular, making it easy for someone with intermediate knowledge of a computer to modify one. Desktop computers are generally more affordable than notebook computers. This is because no extra effort is needed to miniaturize the components, nor to find design solutions to the thermal management problems that arise from the use of components that emit heat in a compact space. [edit] Components Fan - cools the computer. These are present on most computers. There are often multiple, one to cool the processor(see below), one in the power supply, and possibly additional ones for the graphics card and general cooling. Motherboard (a.k.a. mainboard) - links all of the components together and routes data. HDD (hard disk drive) - location where all information can be stored even when power is off. ODD (optical disc drive) - reads most or all types of CDs and/or DVDs. Processor - The main brain of the computer. CPU Cooler - cools the processing unit. Typically a fan combined with a heatsink. RAM - short-term data storage, volatile (data is erased when the computer is powered off) Graphics card - codes video output and delivers to monitor. Physics card - performs physics computations in some modern games. Sound card - codes sound output and delivers to speakers. Speakers - deliver sound. Modem - used to access data via a telephone line (dial-up connection). Used to access BBS and the Internet. Network card - allows the computer to be linked to a computer network where it can communicate with other computers. Also used as a means of accessing the Internet via a broadband connection.

Alternative terms include attorney-at-law, attorney and counselor (or counsellor) at law, attorney, and lawyer.[1] The U.S. legal system has a united legal profession, and does not draw a distinction between lawyers who plead in court and those who do not. Many other common law jurisdictions, as well as some civil law jurisdictions, have a separation, such as the solicitor and barrister/advocate split in the United Kingdom and the advocate/civil law notary split in France. There is also no delegation of routine work to notaries public or their civil law equivalent in the American system. acting kids acting kids car insurance quote The contract can be renewable annually or monthly.

The term Attorney General is used to designate the chief law enforcement officer of a state or other political jurisdiction. The Attorney General is a lawyer who represents the government, prosecutes criminal cases, defends the government from lawsuits against it, and brings civil lawsuits to enforce consumer protection, antitrust, and other laws. In the Federal Government of the United States, the Attorney General is a member of the Cabinet and as head of the Department of Justice is the top law enforcement officer and lawyer for the government. The attorney general may need to be distinguished from the Solicitor General, a high Justice Department official with the responsibility of representing the government in the Supreme Court. In cases of exceptional importance, however, the Attorney General may choose to represent the government himself/herself in the Supreme Court. The individual U.S. states also have State Attorneys General with similar responsibilities. The majority of state Attorneys General are chosen by popular election, as opposed to the U.S. Attorney General who is a Presidential appointee. voice acting voice acting insurance The type and amount of health care costs that will be covered by the health plan are specified in advance, in the member contract or Evidence of Coverage booklet.

A small-town corporate lawyer in a small firm may deal in many short-term jobs such as drafting wills, divorce settlements, and real estate transactions, whereas a corporate lawyer in a large city firm may spend many months devoted to negotiating a single business transaction. Similarly, different firms may organize their subdivisions in different ways. Not all will include mergers and acquisitions under the umbrella of a corporate law division, for example. Some corporate lawyers become partners in their firms. |
