COM+

(Component Object Model) Microsoft's object-oriented programming architecture and operating system services for developing applications. See also Component Services.

GUI

(Graphical User Interface) An easy to use, intuitive interface for a computer operating system. Most GUIs require a pointing device, such as a mouse, to operate efficiently. One of the world's first GUI-based operating systems was the Apple Mac OS, released in 1984. Thereafter, Microsoft produced their Windows family of products based around their GUI.

CMYK Color Model

(Cyan Magenta Yellow Key [Black] color model) Subtractive color model used by print devices. CMYK printing involves use of halftone screens.

(Demilitarized Zone) A private network connected to the Internet must be protected against intrusion from the Internet. However, certain services may need to be made publicly accessible from the Internet (web and email, for instance). One solution is to put such servers in a DMZ. The idea of a DMZ is that traffic cannot pass through it. If communication is required between hosts on either side of a DMZ, a host within the DMZ acts as a proxy. It takes the request and checks it. If the request is valid, it re-transmits it to the destination. External hosts have no idea about what (if anything) is behind the DMZ. A DMZ is implemented using either two firewalls (screened subnet) or a single three-legged firewall (one with three network ports).

The original 16-bit version (FAT16, but often simply called FAT) was replaced by a 32-bit version that is almost universally supported by different operating systems and devices. A 64-bit version (exFAT) was introduced with Windows 7 and is also supported by XP SP3 and Vista SP1 and some versions of Linux and macOS. There is also a 12-bit version used to format floppy disks.

HCL

(Hardware Compatibility List) Before installing an OS, it is vital to check that all the PC components have been tested for compatibility with the OS (that they are on the Hardware Compatibility List [HCL] or Windows Logo'd Product List).

serial port

Asynchronous serial transmission (RS-232) is one of the oldest PC bus standards. A serial port is a legacy port that can be used to connect devices such as modems, mice, and Uninterruptible Power Supplies (UPS). Serial ports transmit data bit-by-bit using a single data line at a speed of up to about 115 Kbps. Although the original serial port used a 25-pin male D connector, most PCs today use a male DB9 (9-pin) port. The serial port is now little used but does provide an "out-of-band" means of configuring network appliances such as switches and routers.

chipset

The chipset provides communications between different components by implementing various controllers (for memory, graphics, I/O, and so on). Historically, "fast" controllers (memory and video) were part of a "northbridge" chipset, placed close to the CPU and system memory. Slower buses were part of a "southbridge" chipset. In modern PC architecture, video and memory controllers are part of the CPU (on-die), the northbridge would mostly handle PCI Express adapters, and the southbridge would host SATA, USB, audio and LAN functions, plus PCI/PATA legacy bus support.

drive controller

The controller is the circuitry in the disk unit that allows it to put data on the bus, which the HBA shuttles to the CPU or RAM.

desktop

The desktop is at the top of the object hierarchy in Explorer, containing the Computer, Documents, Network, and Recycle Bin objects. The desktop also stores shortcuts to programs, files, and system objects.

In a star topology, nodes are connected to a single point while in a hub topology, all nodes connect to the same media and share bandwidth. A ring topology means that communications travel from node-to-node in a loop. In a full mesh network, each node is linked to every other node, but partial meshes are far more common. A hybrid topology uses elements of different topologies, such as a logical bus but physical star.

Microsoft Windows

Windows started as version 3.1 for 16-bit computers. A workgroup version provided rudimentary network facilities. Windows NT 4 workstations and servers (introduced in 1993) provided reliable 32-bit operation and secure network facilities, based around domains. The Windows 9x clients (Windows 95, 98, and Me) had far lower reliability and only support for workgroups, but were still hugely popular as home and business machines. Windows 2000 and Windows XP workstations married the hardware flexibility and user interface of Windows 9x to the reliability and security of Windows NT, while the server versions saw the introduction of Active Directory for managing network objects. The subsequent client releases of Windows (Vista and Windows 7) featured a substantially different interface (Aero) with 3D features as well as security improvements. The latest client versions—Windows 8 and Windows 10—are designed for use with touchscreen devices.
