Helix Software
Helix Software Company, Inc. was a New York City based software company founded in October 1986. The company developed software tools and utilities for DOS and Windows. In 1993, Helix licensed some of its memory management technology to Microsoft for use in MS-DOS 6.0. Microsoft subsequently released Helix's memory management technology as part of the MEMMAKER and EMM386 DOS commands. The company pioneered several technologies, including virtual memory compression systems, switching between multiple protected mode operating environments, use of off-screen video RAM, and highly recoverable fixed storage systems. On 1 December 1997, Helix Software merged with McAfee, Network General, and PGP Corporation in a pooling of interest transaction, the resulting company was named Network Associates. Helix's products were integrated with the other companies' products as well as with products from the subsequent acquisitions of Cybermedia and Dr Solomon's Antivirus. The combined ...

Helix HeadRoom
HeadRoom is a DOS context switching and multitasking memory manager produced by Helix Software Company in the late 1980s and early 1990s. HeadRoom managed multiple terminate-and-stay-resident programs (TSRs) and was the first TSR manager to allow sharing of address space and interrupts among TSRs in DOS. HeadRoom v1.0 was released in September 1988. In April 1989, Helix Software released HeadRoom v1.1 together with the "HeadRoom Network Extensions." This version added support for network communications processes. The HeadRoom Network Extensions intercepted and buffered NETBIOS and TCP/IP communications requests, allowing HeadRoom to manage network communications software such as mainframe Terminal Emulators and e-mail programs. The background communications of these programs would continue while the programs were swapped out. HeadRoom would reactivate the swapped-out programs when activity occurred on the NETBIOS or TCP/IP sockets. In October 1989, Helix Software released He ...

Virtual Memory Compression
Virtual memory compression (also referred to as RAM compression and memory compression) is a memory management technique that utilizes data compression to reduce the size or number of paging requests to and from the auxiliary storage. In a virtual memory compression system, pages to be paged out of virtual memory are compressed and stored in physical memory, which is usually random-access memory (RAM), or sent as compressed to auxiliary storage such as a hard disk drive (HDD) or solid-state drive (SSD). In both cases the virtual memory range, whose contents has been compressed, is marked inaccessible so that attempts to access compressed pages can trigger page faults and reversal of the process (retrieval from auxiliary storage and decompression). The footprint of the data being paged is reduced by the compression process; in the first instance, the freed RAM is returned to the available physical memory pool, while the compressed portion is kept in RAM. In the second instance, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Privately Held Company
A privately held company (or simply a private company) is a company whose Stock, shares and related rights or obligations are not offered for public subscription or publicly negotiated in their respective listed markets. Instead, the Private equity, company's stock is offered, owned, traded or exchanged privately, also known as "over-the-counter (finance), over-the-counter". Related terms are unlisted organisation, unquoted company and private equity. Private companies are often less well-known than their public company, publicly traded counterparts but still have major importance in the world's economy. For example, in 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for $1.8 trillion in revenues and employed 6.2 million people, according to ''Forbes''. In general, all companies that are not owned by the government are classified as private enterprises. This definition encompasses both publ ...

Tech Companies In The New York Metropolitan Area
Technology companies in the New York City metropolitan area represent a significant and growing economic component of the New York metropolitan area, the most populous combined statistical area in the United States and one of the most populous urban agglomerations in the world. New York is a top-tier global high technology hub. Silicon Alley, once a metonym for the sphere encompassing the metropolitan region's high technology industries, is no longer a relevant moniker as the city's tech environment has expanded dramatically both in location and in its scope. New tech establishments include those of Israeli companies in New York City, at a rate of ten new startups per month, and the technology sector has been claiming a greater share of New York City's economy since 2010.

Helix Multimedia Stacker
A disk compression software utility increases the amount of information that can be stored on a hard disk drive of given size. Unlike a file compression utility, which compresses only specified files—and which requires the user to designate the files to be compressed—an on-the-fly disk compression utility works automatically through resident software without the user needing to be aware of its existence. On-the-fly disk compression is therefore also known as transparent, real-time or online disk compression. When information needs to be stored to the hard disk, the utility compresses the information. When information needs to be read, the utility decompresses the information. A disk compression utility overrides the standard operating system routines. Since all software applications access the hard disk using these routines, they continue to work after disk compression has been installed. Disk compression utilities were popular especially in the early 1990s, when microcom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multimedia Cloaking
DOS Protected Mode Services (DPMS) is a set of extended DOS memory management services to allow DPMS-enabled DOS drivers to load and execute in extended memory and protected mode. Not being a DOS extender by itself, DPMS is a minimal set of extended DOS memory management services to allow slightly modified DOS resident system extensions ( RSX) such as device drivers or terminate-and-stay-resident programs (TSRs) (as so called ''DPMS clients'') to relocate themselves into extended memory and run in 16-bit or 32-bit protected mode while leaving only a tiny stub in conventional memory as an interface to communicate with the conventional DOS environment. The DPMS clients do so through DPMS services provided by a previously loaded ''DPMS server''. The necessary size of the remaining stub depends on the type of driver, but often can be reduced to a few hundred bytes for just the header even for complex drivers. By executing the driver in extended memory and freeing up conventional m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helix Netroom
Netroom (originally styled NETROOM) is a DOS memory manager produced by Helix Software Company in the 1990s. Introduced in August 1990, NETROOM was originally titled "LAN Memory Manager." Version 1.0 of NETROOM was a re-packaged version of Helix's HeadRoom with the HeadRoom Network Extensions, bundled together and targeted to network users. NETROOM loaded network drivers into a virtual machine created using an expanded memory page frame. NETROOM allowed this virtual machine to run as a multitasked background process. NETROOM included support for Novell NetWare, Banyan VINES, and LAN Manager networks. NETROOM was originally available only in multi-user packs starting with a four user license. Helix introduced version 1.10 of NETROOM, in January 1991, with a single-user license. This version included support for Microsoft Windows 3.0, and added an integrated 286 and 386 expanded memory manager.
