The heart of a computer is the central processing unit or CPU. This device contains all the circuitry that the computer needs to manipulate data and execute instructions. The CPU comprises of Motherboards, Micro processor, RAM, ROM, Hard Drives, Video Cards, Sound Cards, Adapters, SMPS (Switch mode power supply)
Serial Advanced Technology Attachment (SATA Hard Drive) is a computer bus primarily designed for transfer of data between a computer and storage devices
Parallel Advanced Technology Attachment (PATA Hard Drive) is a computer bus primarily designed for transfer of data between a computer and storage devices
random access memory (RAM)
Memory that can be read from or written to by a computer or other devices. Information stored in RAM is lost when the computer is turned off.
read-only memory (ROM)
A semiconductor circuit that contains information that cannot be modified.
Static random access memory (SRAM) is a type of semiconductor memory the memory retains its contents as long as power remains on. Whereas Dynamic RAM (DRAM) that needs to be periodically refreshed.
The Accelerated Graphics Port (also called Advanced Graphics Port, often shortened to AGP card) is a high-speed point-to-point channel for attaching a graphics card to a computer motherboard
The Peripheral Component Interconnect, or PCI Standard (in practice almost always shortened to PCI card), specifies a computer bus for attaching peripheral devices to a computer motherboard
An adapter is a physical device that allows one hardware or electronic interface to be adapted (accommodated without loss of function) to another hardware or electronic interface. In a computer, an adapter is often built into a card that can be inserted into a slot on the computer's motherboard
The Device Manager is a Control Panel applet included with Microsoft Windows operating systems that allows the user to display and control the hardware attached to the computer. When a piece of hardware is not working, the offending hardware is highlighted where the user can deal with it. Using this we can update, uninstall and disable the device.
How to go to the device manager ?
Right-click My Computer then select Properties
Select the Hardware tab
Click the Device Manager button
The Windows Registry is a directory which stores settings and options for the operating system. It contains information and settings for all the hardware, operating system software, most non-operating system software, users, preferences of the PC, etc
How do you go to the registry ?
Go to the command prompt and type reg.exe
MSConfig, or System Configuration Utility, is a system configuration utility of Windows operating systems. This tool modifies which programs run at startup, edits certain configuration files, and simplifies
compression
Temporary Internet Files
Temporary Internet Files are the pages viewed of the Internet explorer. They are saved on the computer so that if you later decide to open the same page again it will open faster. Temporary Internet Files improve speed of web browsing and also make possible so called offline browsing
Cookies
a message given to a web browser by a web server. The browser stores the message in a text file. The message is then sent back to the server each time the browser requests a page from the server. The main purpose of cookies is to identify users and possibly prepare customized web pages for them
The partition that contains the Windows operating system and its support files. The boot partition can be, but does not have to be, the same as the system partition.
broadband
Of or relating to communications systems in which the medium of transmission (such as a wire or fiber-optic cable) carries multiple messages at a time, each message modulated on its own carrier frequency by a modem. Broadband connections are typically 256 kilobytes per second (KBps) or faster.
defragmentation
The process of rewriting parts of a file to contiguous sectors on a hard disk to increase the speed of access and retrieval. When files are updated, the computer tends to save these updates on the largest continuous space on the hard disk, which is often on a different sector than the other parts of the file. When files are thus fragmented, the computer must search the hard disk each time the file is opened to find all of the file's parts, which slows down response time
