- DHCP (Dynamic Host Configuration Protocol) is used to dynamically assign IP addresses and other network configuration parameters to clients on a network. It allows for reduced administration compared to static addressing.
- A DHCP lease is the amount of time a client is granted permission to use a particular IP address assigned by the DHCP server. Typical leases are days. The client begins renewing the lease halfway through the period.
- The Client ID is used by DHCP to uniquely identify each client, typically the client's MAC address but can be customized. Proper unique Client IDs are needed for DHCP to function correctly.

Personal computer-hardware
1. Personal computer hardware 1
Personal computer hardware
A personal computer is made up of
multiple physical components of
computer hardware, upon which can
be installed a system software called
operating system and a multitude of
software applications to perform the
operator's desired functions.
Though a PC comes in many different
forms, a typical personal computer
consists of a case or chassis in a tower
shape (desktop), containing
components such as a motherboard.
Motherboard
The motherboard is the main
component inside the case. It is a large
rectangular board with integrated
circuitry that connects the rest of the
parts of the computer including the
CPU, the RAM, the disk drives (CD,
DVD, hard disk, or any others) as well Hardware of a modern Personal Computer. 1. Computer monitorMonitor 2.

ports or the expansion slots.
drive9. Computer keyboardKeyboard10. Computer MouseMouse
Components directly attached to the
motherboard include:
• The central processing unit (CPU) 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 heat sink and fan.
• The chip set mediates communication between the CPU and the other components of the system, including main
memory.
• RAM (Random Access Memory) stores resident part of the current running OS (OS core and so on) and all
running processes (application parts, using CPU or input/output (I/O) channels or waiting for CPU or I/O
channels).
• The BIOS includes boot firmware and power management. The Basic Input Output System tasks are handled by
operating system drivers.
• Internal Buses connect the CPU to various internal components and to expansion cards for graphics and sound.
• Current
• The north bridge memory controller, for RAM and PCI Express
• PCI Express, for expansion cards such as graphics and physics processors, and high-end network
interfaces
• PCI, for other expansion cards
• SATA, for disk drives
• ATA
2. Personal computer hardware 2
• Obsolete
• AGP (superseded by PCI Express)
• VLB VESA Local Bus (superseded by AGP)
• ISA (expansion card slot format obsolete in PCs, but still used in industrial computers)
• External Bus Controllers support ports for external peripherals. These ports may be controlled directly by the
south bridge I/O controller or based on expansion cards attached to the motherboard through the PCI bus.
• USB
• FireWire
• eSATA
• SCSI
Power supply
A power supply unit (PSU) converts alternating current (AC)
electric power to low-voltage DC power for the internal
components of the computer. Some power supplies have a
switch to change between 230 V and 115 V. Other models
have automatic sensors that switch input voltage
automatically, or are able to accept any voltage between those
limits. Power supply units used in computers are nearly
always switch mode power supplies (SMPS). The SMPS
provides regulated direct current power at the several voltages
required by the motherboard and accessories such as disk
drives and cooling fans.
Removable media devices Inside a custom-built computer: the power supply at the

data storage.
• DVD-ROM Drive - a device used for reading data from a DVD.
• DVD Writer - a device used for both reading and writing data to and from a DVD.
• DVD-RAM Drive - a device used for rapid writing and reading of data from a special type of DVD.

information as a CD.
• BD-ROM Drive - a device used for reading data from a Blu-ray disc.
• BD Writer - a device used for both reading and writing data to and from a Blu-ray disc.
• HD DVD - a discontinued competitor to the Blu-ray format.
• Floppy disk - an outdated storage device consisting of a thin disk of a flexible magnetic storage medium. Used
today mainly for loading RAID drivers.
• Iomega Zip drive - an outdated medium-capacity removable disk storage system, first introduced by Iomega in
1994.
3. Personal computer hardware 3
• USB flash drive - a flash memory data storage device integrated with a USB interface, typically small,
lightweight, removable, and rewritable. Capacities vary, from hundreds of megabytes (in the same ballpark as
CDs) to tens of gigabytes (surpassing, at great expense, Blu-ray discs).
• Tape drive - a device that reads and writes data on a magnetic tape, used for long term storage and backups.
Secondary storage
Hardware that keeps data inside the computer for later use and remains persistent even when the computer has no
power.
• Hard disk - for medium-term storage of data.
• Solid-state drive - a device similar to hard disk, but containing no moving parts and stores data in a digital format.
• RAID array controller - a device to manage several internal or external hard disks and optionally some peripherals
in order to achieve performance or reliability improvement in what is called a RAID array.
Sound card
Enables the computer to output sound to audio devices, as well as accept input from a microphone. Most modern
computers have sound cards built-in to the motherboard, though it is common for a user to install a separate sound
card as an upgrade. Most sound cards, either built-in or added, have surround sound capabilities.
Input and output peripherals
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
• Text input devices
• Keyboard - a device to input text and characters by depressing
buttons (referred to as keys or buttons).
• Pointing devices
• Mouse - a pointing device that detects two dimensional motion
relative to its supporting surface.
• Optical Mouse - uses light to determine mouse motion.
• Trackball - a pointing device consisting of an exposed protruding
