PCI
was introduced in 1992 and doubled both the width (to 32 bits) and speed (to 33 MHz) of the previous expansion slot type, ISA. PCI was a parallel, shared bus design - it used multiple wires to transmit a single large data chunk at one time, and only one device can talk at a time. Later revisions allowed for a 64 bit data path and at a speed of 66 MHz.
The PCI Express (PCI-E) expansion slot standard
was introduced in 2002 to replace PCI and AGP expansion slots (below). The PCI-E uses a high-speed serial bus to transmit small pieces of data in succession and a switched communications pathway, allowing multiple devices to talk simultaneously.

Scheduling
A processor core can only run a single process at any given point in time. That means a dual-core processor can only run two processes simultaneously. Scheduling allows users to have more processes open, providing an illusion of multitasking by rapidly switching the processor core(s) between tasks. The kernel handles scheduling automatically, but some system calls imply that the kernel will switch to a different process, such as calls that quit a running process or wait for user input.

RAM
Every personal computer also has Random Access Memory (RAM). Unlike ROM, RAM loses content when the computer is powered off. RAM provides a storage location for data that the CPU can access and manipulate quickly. It also allows software and other data to run continuously without requiring access to more permanent storage
ROM
Every personal computer has Read-Only Memory (ROM), which will not lose its content when the computer is powered off. ROM chips are loaded with a Basic Input/output System (BIOS) that interfaces between the system hardware and software, and enables the computer to boot successfully
Read-Only Memory (ROM)
Every personal computer has Read-Only Memory which will not lose its content when the computer is powered off. ROM chips are loaded with a Basic Input/output System (BIOS) that interfaces between the system hardware and software, and enables the computer to boot successfully.

If you go to the Chart Layouts pane under Chart Tools - Design, you can choose to edit the graph's fields. Quick Layout will show you preset layouts that could include a Chart Title, Axis Titles, Legend, etc. The Add Chart Element will allow you to add items to the graph individually. If you hover over an element to be added, you can select from the default items, or click More (insert element) Options. From there, a pane will open from the right-side of the Excel window, and you can finish editing your final product there. After the graph is created, it can be resized using the anchors. You may also use the other panes (Chart Styles, Data, Type, Location) and the three floating options (plus "+" sign, paint brush, funnel) on the upper right-hand corner of the selected graph to continue editing the graph.

Papercut is linked to users' unity accounts, and is therefore automatically synced on laboratory machines when the user logs in. This allows for immediate printing directly from the lab computer. This system can only be used while connected to the NC State system from a lab machine or wireless network.
